What you will find 

A cheap machine can become an expensive investment if it solves the wrong problem. Before comparing listings, identify what limits production: insufficient operating hours, excessive scrap, difficulty meeting tolerances, lengthy setup, or dependence on an outside supplier. Each constraint calls for a different response. More cutting capacity, for example, achieves little if orders already wait at final inspection.

01 

## Start with the bottleneck the machine must solve

Turn the need into a measurable specification. List the products, materials, dimensions, tolerances, batch sizes, and monthly volume that customers are likely to buy. Add delivery requirements and the hours actually available. Saying the business needs to grow provides little guidance. Specifying another 1,000 acceptable parts per month within a defined tolerance gives the comparison a practical basis.

Separate demonstrated demand from sales expectations. Accepted orders, repeat-purchase history, and contracts support an estimate of utilization, although cancellations and volume changes remain possible. A promising customer conversation carries less weight than a formal order. Neither makes hoped-for sales into existing receivables. This distinction affects how much uncertainty the business can absorb without straining cash.

Summarize the bottleneck, relevant products, required capacity, quality requirements, and demand evidence on one page. Include alternatives such as repairing the existing machine, temporary subcontracting, or reorganizing shifts. Compare new and used equipment only after establishing that a purchase addresses the production problem. Otherwise, an attractive offer may tie up money while leaving the original constraint unresolved.

02 

## Compare usable capacity rather than catalog speed

Advertised speed usually describes particular conditions: a specified material, suitable tooling, continuous operation, and favorable settings. Actual production includes batch changes, cleaning, measurement, adjustments, and interruptions. Usable capacity must therefore combine available time, effective operating speed, and the proportion of acceptable parts. Scheduled hours multiplied by nominal speed alone will often overstate output.

Suppose a machine makes 10 parts per hour under ideal conditions and has 176 scheduled hours per month. Nominal capacity is 1,760 parts. A combined availability, performance, and quality factor of 75% reduces estimated output to 1,320 good parts. At 65%, output is 1,144. These percentages are planning assumptions, not universal characteristics of new or used machinery, and must be supported for each alternative.

Observe a complete cycle using representative parts to support the chosen factor. Time setup, machining or processing, unloading, measurement, and corrections. A demonstration using one simple part can conceal tool changes or deterioration across a batch. Where product families differ substantially, estimate capacity by family and likely order mix. An unexplained average can hide the workload that actually determines delivery performance.

Operating headroom has value. A machine that can barely supply expected demand depends on consistently favorable conditions. Additional capacity can absorb rework, urgent orders, and short stoppages. However, excessive idle capacity ties up resources. Seek a defensible margin relative to demand and disruption risk. In the example, both machines exceed the additional 1,000-part requirement, but their remaining capacity differs.

03 

## New and used machines carry different risks

New machinery often provides a more predictable configuration, organized documentation, and supplier-defined warranty terms. These features can reduce uncertainty without proving suitability for the process. Manufacturing delays, incomplete installation, superficial training, and distant service support remain possible. New condition does not replace performance testing or careful reading of contractual exclusions and responsibilities.

Used machinery may provide capacity for a lower initial payment, but it requires deeper investigation. Maintenance history, operating hours, electrical modifications, collisions, and component availability all affect risk. Two machines of the same model may be in very different condition. Age and appearance help identify questions; neither independently establishes remaining useful life or the cost of keeping the equipment productive.

Used equipment can be a reasonable choice for a familiar process when parts and service are accessible and inspection is satisfactory. New equipment may deserve greater weight where tolerances are critical, downtime is expensive, or integration requirements are specific. Assess refurbished machinery separately: establish what was replaced, by whom, with which components, and under whose responsibility. Fresh paint is not evidence of technical refurbishment.

Compare complete, actual alternatives. A used machine ready to operate differs from one sold dismantled. A new machine without installation differs from a proposal covering delivery and acceptance in production. Standardize scope before negotiating price. Apparent discounts may shrink once transport, modifications, tooling, and support are included. Record exclusions explicitly so that missing work does not disappear from the budget.

04 

## Screen the documents before paying for inspection

Request the seller's identification, manufacturer, model, serial number, configuration, and included accessories. Match these details against the physical identification plate and supplied documents. Establish precisely which asset is being negotiated and whether the seller can transfer it. Previous financing, leasing, or third-party ownership may require further examination of ownership, restrictions, and transfer conditions before proceeding.

Ask for manuals, electrical diagrams, maintenance records, available alarm histories, and evidence of major interventions. Missing documents do not prove a defect, but they increase uncertainty and may raise installation or diagnostic costs. List the gaps and the likely cost of resolving them. If the manufacturer no longer supplies a required manual or component, reflect that limitation in the risk assessment and budget.

Check software, licenses, administrative access credentials, and whether usage rights can transfer. Keep credentials out of proposals and reports. A physically functional machine may depend on a license linked to its previous owner. Controllers, design software, and communication functions need assessment under their applicable contracts. Buying the physical asset does not automatically transfer every associated software right or access entitlement.

Use this screening to decide whether further expenditure is justified. A mismatched serial number, an unexplained ownership history, or refusal to allow tests warrants pausing the negotiation until the facts are clear. Obtain appropriate professional review for ownership, restrictions, or contractual liability. A discount cannot compensate for being unable to establish what is being bought or whether the intended use is legally available.

05 

## Inspect under conditions that reveal wear

Arrange inspection by a professional familiar with the technology and independent of the seller. Agree on the scope beforehand: structure, drives, controls, auxiliary systems, safety, and sample production. Record limitations such as inaccessible components or an inability to process a particular material. A useful report distinguishes observations, measurements, and unresolved questions, rather than presenting an unqualified conclusion.

Where technically appropriate, observe startup from cold and operation after warm-up. Noise, vibration, play, leaks, and thermal variation may emerge at different stages. For a machining center, positioning accuracy, spindle condition, and tool-changing performance warrant specific attention. Select criteria from the intended process and relevant technical recommendations. A machine that runs smoothly briefly may still fail to hold production tolerances.

Produce a test batch using an agreed drawing, raw material, and acceptance criteria. Measure with suitable instruments and examine variation across the batch. A seller-selected sample provides limited evidence. Photographs and videos help document condition, but they do not replace measurements or independently demonstrate sustained accuracy. Preserve the test conditions so that later comparisons can distinguish machine behavior from changes in materials or setup.

Classify findings by consequence: a barrier to operation, repair required before installation, scheduled maintenance, or an optional improvement. Estimate cost, lead time, and confidence for each. Keep critical defects visible rather than burying them among cosmetic details. If a significant fault remains unexplained, make the purchase conditional on investigation. An unsupported precise repair allowance can create confidence that the evidence does not justify.

06 

## Confirm that the factory can receive and operate it

A machine that passes testing at the seller's premises may not operate properly at its destination. Check electrical supply, power demand, grounding, compressed air, cooling, extraction, and environmental conditions. Assess the floor, foundations, maintenance access, and material circulation. Complete these checks before accepting payment commitments that depend on rapid installation. Infrastructure is part of the investment, not an afterthought.

Plan the entire route: removal, lifting, transport, unloading, and positioning. Gates, corridors, available height, and handling capacity can turn a straightforward delivery into a specialist operation. Assign responsibility for packaging, protection, insurance, and damage. Establish who prepares the machine for transport and how alignment, sensitive components, and accessories will be preserved. A transport quote must match the work actually required.

Assess safety against the real application, its hazards, and relevant Brazilian requirements, with appropriately qualified technical assistance where needed. Removed guards, altered controls, and inadequate stopping systems are substantive issues. Budget for identified modifications and resolve conditions that prevent safe operation. Production should not begin simply to recover the investment while a blocking safety issue remains outstanding.

Identify who will operate, program, and maintain the machine. Training costs money and uses hours unavailable for production. If only one person knows the equipment, absence or departure may interrupt the purchased capacity. Include procedures, parameter records, and training for substitutes. Productive capacity comes from equipment, infrastructure, and people working together; acquiring the machine alone does not establish that capability.

07 

## Define the boundaries of total investment cost

Organize the comparison into three groups: spending required to start operation, costs during use, and recoverable value on exit. The first includes purchase, freight, installation, modifications, initial tooling, and refurbishment. The second includes energy, incremental staffing, maintenance, and other attributable operating costs. The third estimates resale or disposal proceeds after the costs required to end use and realize that value.

Give working capital its own line. It represents resources tied up between purchasing inputs, producing goods, and collecting customer payments, net of supplier payment terms. It is not automatically a permanent expense: some may be released when operations end. Nevertheless, the cash must be available during the project. An investment can look attractive over its full life while remaining impossible to fund through its payment schedule.

Apply the same boundary to both alternatives. If each requires a new operator, include the full employment cost in both. If an existing team has available hours, explain the incremental cost and any alternative use of that time. Avoid allocating unrelated overhead arbitrarily, but include costs caused by the purchase. A comparison becomes misleading when one option receives a complete cost estimate and the other only a purchase price.

Prevent double counting. Refurbishment paid for before startup should not reappear in full in monthly maintenance. Accounting depreciation and the purchase payment serve different purposes and should not be indiscriminately added in a cash analysis. Tax and accounting treatment need specific assessment. State what the initial comparison includes, what it excludes, and which unresolved items require specialist input before a final commitment.

08 

## Worked example: two offers for the same production need

Consider a small Brazilian manufacturer already delivering 1,000 parts monthly and assessing another machine to sell 1,000 additional parts. Every amount and operating assumption in this example is hypothetical arithmetic, not a market price, rate, or forecast. Assume both machines meet the drawing. With 176 monthly hours and an ideal rate of 10 parts per hour, combined factors of 75% and 65% yield 1,320 and 1,144 good parts respectively.

The new machine costs R$240,000. Add R$8,000 for freight, R$14,000 for infrastructure, R$6,000 for installation and training, and R$4,000 for initial tooling. These items total R$272,000. Another R$10,000 of incremental working capital brings the initial requirement to R$282,000. That working-capital estimate assumes particular customer and supplier terms, which still need confirmation rather than acceptance as a fixed equipment cost.

The used machine costs R$140,000. Freight of R$8,000, infrastructure of R$14,000, installation and training of R$8,000, initial refurbishment of R$20,000, and tooling of R$6,000 bring the subtotal to R$196,000. Adding the same R$10,000 of working capital gives R$206,000. Its initial cash advantage is R$76,000. Refurbishment appears once, before operation; recurring maintenance is assessed separately.

Each additional part sells for R$80 and incurs R$46 in materials, consumables, packaging, and variable selling expenses. The R$34 difference is contribution before the machine's monthly operating costs. Selling 1,000 additional parts produces R$80,000 of revenue, R$46,000 of variable costs, and R$34,000 of contribution. The company's existing 1,000-part output is excluded because the comparison concerns the incremental investment.

09 

## The lowest initial payment may not mean the lowest accumulated cost

Assume monthly costs for the new machine of R$2,000 in energy, R$8,000 in incremental staffing, R$1,500 in maintenance, and R$1,000 in other operating expenses: R$12,500 altogether. For the used machine, assume R$2,600 in energy, R$8,000 in staffing, R$2,900 in maintenance, and R$1,000 in other expenses: R$14,500. Each estimate requires technical or commercial support; these are not inherent cost differences between all new and used machines.

At 1,000 parts sold monthly, estimated operating cash generation is R$21,500 for the new machine and R$19,500 for the used one, subtracting monthly operating costs from R$34,000 of contribution. Over 36 months of stable operation, operating costs total R$450,000 and R$522,000. Assume net resale proceeds of R$80,000 and R$45,000 respectively, plus full recovery of the R$10,000 working capital in each case.

Within this boundary, nominal total cost for the new machine is R$282,000 plus R$450,000, less R$80,000 resale proceeds and R$10,000 recovered working capital: R$642,000. For the used machine, R$206,000 plus R$522,000, less R$45,000 and R$10,000, equals R$673,000. Materials and variable costs per part are omitted from these totals because both alternatives have the same assumed sales volume and unit variable costs.

The new machine has a R$31,000 lower nominal cost despite requiring more initial cash. As a cross-check, accumulated operating generation after the initial investment and recoveries is R$582,000 for new and R$551,000 for used. These are model outputs, not promised profit or funder returns. Interest, taxes, inflation, and implementation are excluded, and cash flows are not discounted to present value. Including them may change the decision.

10 

## Put the investment on a cash-flow timeline

The preceding comparison covers 36 months of stable operation. It does not establish how much cash is needed between signing and collecting the first customer payment. Build a separate timeline around verifiable events: ordering, site preparation, inspection, transport, installation, acceptance, and collection. Incorporate implementation spending and possible delays into the final decision. Expected operating efficiency cannot fund payments that fall due before production starts.

For the new machine, suppose the seller requests R$96,000 on ordering and R$144,000 at a contractual acceptance stage. Together these equal the R$240,000 purchase price; the other R$42,000 in the initial budget has its own payment schedule. For the used machine, a hypothetical R$14,000 deposit and R$126,000 balance complete the purchase price. The remaining R$66,000 covers the other budgeted items.

Payment order matters as much as total spending. Infrastructure may require payment before delivery, refurbishment before transport, and materials before customers pay. The example's R$10,000 working-capital provision is sufficient only if net payment terms support it. If all R$46,000 of variable costs become payable before any collection, that outflow alone exceeds the assumption. Rebuild the working-capital estimate from actual timing and overlapping obligations.

Maintain a risk-based liquidity reserve separately from expected costs. A hypothetical R$30,000 reserve for either option raises desired available resources to R$312,000 for new and R$236,000 for used. It is not an expense unless consumed. Record the lowest projected cash balance and the event causing it. This shows whether the business can withstand implementation pressures, rather than merely whether the investment eventually appears economical.

11 

## Test weaker demand, breakdowns, and delays separately

First reduce monthly sales to 600 parts while retaining R$34 contribution per part and the model's monthly operating costs as a conservative assumption. Contribution falls to R$20,400, leaving R$7,900 for new and R$5,900 for used before financing and other excluded items. Energy may change with output in practice. Holding it constant here isolates the demand effect and makes the scenario easier to interpret.

Within this simplified boundary, covering monthly operating costs requires approximately 368 parts for new and 427 for used, rounding upward after dividing R$12,500 and R$14,500 by R$34. These figures are not full investment break-even volumes. The initial outlay, financial obligations, and other applicable costs still need coverage. A loan installment would increase monthly cash requirements beyond the operating-cost calculation.

Next assume a breakdown affecting only the used machine: an extraordinary R$18,000 repair and 200 lost sales that cannot be recovered. Lost contribution is R$6,800. With other costs unchanged, the combined impact is R$24,800 beyond the base budget. If production can be subcontracted or delivered later, recalculate the impact. Do not record sales as permanently lost while simultaneously assuming their full recovery elsewhere in the model.

Also test a delayed startup. Postponing a month that would generate R$21,500 or R$19,500 delays that cash; the lasting effect depends on the horizon, recoverable orders, and costs incurred while waiting. Do not automatically add lost net generation to every cost already included in it. For each scenario, identify the cause, affected cash-flow lines, and available response. This prevents overlapping assumptions from exaggerating or concealing exposure.

12 

## Negotiate terms that reduce identifiable uncertainty

Start negotiation with scope and evidence. If inspection identifies a worn component, obtain a diagnosis and repair estimate before requesting a discount. A R$10,000 reduction may be insufficient if repair costs R$8,000, requires specialist transport, and interrupts deliveries. Separate estimated expenditure, lead time, and residual uncertainty so that the negotiated response reflects the full consequence rather than one repair invoice.

Possible arrangements include seller repairs before delivery, a discount with work performed by a third party, component replacement, or payment linked to acceptance. Each allocates responsibility differently. Specify what must happen, how completion will be demonstrated, and what follows if the condition is unmet. A verbal promise of assistance does not establish response time, coverage, or a workable remedy when the machine cannot produce.

Tie acceptance criteria to the actual process: test product, tolerance, cycle time, accessories, and installation conditions. Define who supplies materials and measuring instruments, who witnesses the trial, and how disagreements are handled. Avoid demanding performance that cannot be reproduced at the destination. A useful test reflects the contracted application and records its limits clearly enough to support an objective discussion.

Recognize conflicts of interest. A seller-recommended technician may know the equipment well while having an incentive to minimize defects. Buyers may overstate problems to obtain a discount. Independent assessment and agreed criteria help reduce this tension. Where access is insufficient for a conclusion, suspending the purchase may be the appropriate response. Missing information should remain an uncertainty, rather than becoming an unsupported favorable assumption.

13 

## Build an investment file another person can review

A stronger project connects demand, capacity, inspection, and cash through a reviewable chain. Assemble the production specification, comparable offers, technical report, installation quotations, and calculation details. Identify the source of each figure. An entrepreneur's estimate, an inspector's measurement, and a supplier's formal commitment have different evidential weight. Record assumptions and unresolved items so that a reviewer can challenge the reasoning.

KEZS connects entrepreneurial projects and potential funders through technology and intermediation. Presenting an equipment purchase as a structured project can help explain its needs, assumptions, and risks. Investors perform their own diligence and make their own decisions; KEZS does not assign a credit score. Documentation should support scrutiny rather than imply approval. Neither a project presentation nor the purchase itself guarantees funding.

Match any external funding structure to the equipment's cash cycle and its distinct rights. Loans create repayment obligations. Existing eligible receivables require verifiable rights and conditions and differ from hoped-for sales. Equity carries ownership rights and business risk; convertible instruments depend on their conversion and payment terms. A donation to a nonprofit is neither an equity investment nor a promise of financial return.

Brazilian legal boundaries also matter. An MEI cannot admit equity partners while remaining MEI. Public securities distribution and regulated financial activities require appropriate structures and providers; technology or a CNAE classification is not authorization. Document obligations, fees, conflicts, uncertainty, and potential loss. No structure guarantees approval, repayment, profitability, liquidity, or preservation of capital, and these possibilities must remain visible beside potential benefits.

14 

## Assign responsibility for the decision and acceptance

Equipment purchases require skills rarely concentrated in one person. Production defines products, volume, and pace; maintenance assesses condition and support; quality validates measurements and acceptance criteria. Finance builds the payment timeline and tests commitments. The safety lead evaluates installation and operating hazards. The entrepreneur integrates these assessments into a decision while retaining technical reservations in the record.

Disagreements are useful when their causes and consequences are explicit. Production may favor used equipment for faster delivery while maintenance identifies unavailable parts. Finance may prefer a smaller deposit while quality requires demonstrated dimensional stability. Turn each objection into verifiable information: confirmed replacement lead time, another trial, a quotation, or a contractual condition. Rank alone does not resolve the underlying production risk.

Record who recommends purchase, who authorizes payments, and who confirms acceptance. In a small company, one person may perform several roles; seek a second review of critical points in proportion to the business's size. This reduces pressure to pay merely to fulfill a commercial promise before verifying the machine. It also prevents later problems from becoming ownerless because responsibility was never assigned.

After installation, acceptance should combine technical evidence and documentary conditions required by the contract. Physical delivery does not prove validated capacity. Record outstanding items, owners, and deadlines, distinguishing issues that block operation from adjustments that can safely occur during use. Start production only within those conditions. Pressure to invoice customers does not make a critical unresolved safety or performance issue less consequential.

15 

## Correct the errors that distort the comparison

A common mistake is treating additional revenue as money available to pay for the machine. The example's R$80,000 monthly revenue is not free cash generation. It must cover R$46,000 of variable costs and R$12,500 or R$14,500 of operating costs, plus excluded items. Reconstruct receipts, payments, and due points, including sales not yet collected. An invoice may support revenue recognition without providing cash for the next obligation.

Another error is extending a seller's demonstration beyond its conditions. An easy material and a long batch do not establish the same cycle for complex parts and short batches. Use representative samples and an estimated range where the sales mix is uncertain. If testing cannot occur before purchase, reflect that gap in contractual terms and the decision. A spreadsheet should preserve the uncertainty rather than silently replace it with nominal performance.

Do not let resale assumptions decide the result without scrutiny. Removing all resale and working-capital recoveries gives nominal outflows of R$732,000 for new and R$728,000 for used. The apparent advantage switches to used by R$4,000. This does not imply zero exit value; it shows dependence on the assumed recoveries. Examine whether R$80,000 and R$45,000 are plausible net proceeds and whether the working capital can actually be released.

An organized file is not automatically truthful evidence. An invoice, photograph, or report may be incomplete or concern a different machine. Control versions, authorship, access, and links to the serial number. Keep private documents off public blockchains. Blockchain integrity does not establish the truth of source information, legal ownership, reserve solvency, or payment guarantees. A tamper-resistant record still requires verification of what it records.

16 

## Conclude with purchase conditions and a review of actual results

Explain why the chosen option best addresses the bottleneck within the business's cash constraints and tolerable risk. Here, used equipment requires R$76,000 less initially, while new equipment has a lower nominal cost over the assumed horizon. Neither result settles the decision without checking available funds, installation, support, and residual-value sensitivity. Correcting one important assumption may change the preferred alternative.

Set objective conditions for proceeding: satisfactory documentation, completed inspection, budgeted infrastructure, demonstrated performance, and payments compatible with liquidity. Also define reasons to withdraw or renegotiate, such as structural damage, nontransferable software rights, or additional costs above an agreed limit. Money already spent on visits and analysis should not force completion of a poor purchase. Those sunk costs cannot make unsuitable equipment suitable.

After startup, track good parts per hour, scrap, stoppages, setup time, maintenance, and actual cash flows against the project's assumptions. If capacity falls, determine whether equipment, process, tooling, or training is responsible before buying another machine. If demand falls short, revise scheduling, purchasing, and commitments. Correct the cause rather than expanding investment impulsively on the assumption that more equipment will solve it.

Close the cycle with a documented review of what was delivered, what commissioning actually cost, which assumptions held, and what actions remain. Keep supporting records and reports under appropriate access controls without unnecessary disclosure of personal or commercial information. A sound purchase turns a production need into usable capacity, with understood obligations and room to manage events the original budget could not fully predict.

FAQ 

## Frequently asked questions.

### Should a used machine cost a fixed percentage of a new one's price?

No single percentage resolves the decision. Compare the discount with technical condition, configuration, accessories, estimated remaining life, support, and commissioning cost. A machine at half the price may need expensive refurbishment and scarce components. A more expensive used unit may offer complete documentation and immediate availability. Compare equivalent scopes and use inspection findings to explain price differences. Neither age nor the size of a discount proves quality, and a percentage alone says nothing about whether the machine can meet the required process.

### How should a business decide if new equipment has a lower total cost but used equipment fits its cash position better?

Assess the lowest cash balance during implementation and resilience under adverse scenarios. In this example, new equipment requires another R$76,000 initially and has a R$31,000 nominal advantage over the assumed horizon. That estimated saving cannot solve an immediate liquidity shortage. Examine the cost and obligations of obtaining additional funds, account for cash-flow timing, and confirm that the used alternative remains technically acceptable. If neither leaves adequate operating liquidity, postponement or subcontracting may be more coherent than forcing a purchase.

### What is the payback period for the example machines?

Dividing the initial requirement by stable monthly operating generation gives simple payback of approximately 13.1 months for new equipment: R$282,000 divided by R$21,500. For used equipment, R$206,000 divided by R$19,500 gives approximately 10.6 months. This measure excludes implementation, the time value of money, interest, taxes, and operating variation. It does not guarantee capital recovery. The used machine's shorter simple payback does not contradict the new machine's lower total cost over the assumed horizon: one measures a simplified recovery interval, while the other compares accumulated costs and recoveries.

### Can a machine be bought without producing a test part?

A purchase can be negotiated on that basis, but uncertainty increases and must be acknowledged. Disconnected or dismantled equipment prevents observation of important behavior. Establish why testing is unavailable, which independent checks remain possible, and the consequences of an undetected defect. Payment conditions, rejection rights, or later inspection can be addressed contractually, with appropriate review of their practical enforceability. They do not themselves establish performance. If the essential risk cannot be bounded adequately, the lack of a test may justify abandoning the purchase.

### Does a warranty eliminate the need for maintenance and downtime reserves?

No. Coverage depends on the contract and may exclude wear, travel, consumables, incorrect installation, or production losses. Even a covered repair may involve waiting for diagnosis and parts. Review coverage, response times, transport responsibilities, and the procedure for obtaining service. Size the reserve around the exposure that remains and establish an operating response, such as an alternative supplier. Warranty, preventive maintenance, and liquidity serve complementary purposes. None ensures that a stoppage will be brief or that every related cost will be reimbursed.

### What should be shared with a potential funder without exposing excessive information?

Present the production need, appropriately detailed demand evidence, equipment offers, inspection results, complete budget, and cash-flow scenarios. Identify assumptions, unresolved issues, and responsible people, allowing further examination during diligence. Restrict personal information, industrial know-how, and sensitive commercial terms to authorized recipients with a defined purpose and suitable access controls. A public summary need not reproduce entire contracts or customer records. Transparency means providing enough reliable information for assessment while protecting material that does not need wider circulation; it does not require placing private documents on a public blockchain.

### What should happen if the delivered machine produces less than expected?

Distinguish a failure to meet agreed acceptance criteria from a planning error. Compare actual conditions with the agreed trial: material, tooling, program, operator, infrastructure, and measurement. Record cycle times, rejected parts, and alarms to locate the cause. Invoke contractual responsibilities where a demonstrable discrepancy exists, and correct process or training problems where they explain the shortfall. Rebuild the cash forecast using observed capacity and restrain commitments based on output not yet achieved. Buying additional capacity before completing this diagnosis may increase spending without resolving the constraint.
