Show actual trial spending and repeat-purchase economics separately. The free sample is a real feature of the trial transaction, but it is not automatically the price available for normal fleet supply. Preserve the measured service evidence, obtain a current comparable offer for repeat purchasing and label any future-cost assumptions clearly before deciding whether the candidate is economical.
Separate promotional trial spend from repeat purchase economics
Record what the sample arrangement actually included: the identified blade, associated components and any support or freight that was provided under the trial terms. Do the same for the purchased control. Avoid assigning a zero total cost simply because the blade itself was free; other recorded resources may still have been consumed. Keep the actual transaction accurate without pretending it represents the recurring acquisition cost.
The quote-comparison guide helps normalize the supply scope. For this question, request the candidate's ordinary quoted configuration, unit, included components and applicable delivery scope for the intended purchase. Do not substitute a verbal indication for a confirmed offer when the price is material to the decision. If normal pricing is not yet available, mark the economic comparison incomplete rather than filling in a favorable assumed price from the sample's invoice.
Request the normal supply price and included scope for the candidate
Keep performance observations independent of the promotional acquisition arrangement. Record exposure, condition, service outcome and removal reasons using the same definitions as the control. A free part can provide useful field evidence, but its price should not change how finish quality or wear is scored. Likewise, a supplier-funded trial should not lead the report to omit an unfavorable event or treat support unavailable in normal service as an ordinary operating condition.
Build a repeat-supply scenario using the confirmed quotation and the observed service data at their supported scope. State where extrapolation or other assumptions enter, especially if the sample's service interval is unfinished. Keep required changeover components and workshop effort consistent across options. Do not claim guaranteed future savings from one free sample, and do not assume the supplier will repeat complimentary supply unless an actual approved arrangement establishes that.
Report measured performance independently of a temporary free sample
Present the actual trial outlay as one result and the modeled repeat-purchase comparison as another. Explain which inputs are measured, quoted or assumed. If the purchasing conclusion depends strongly on an unconfirmed price or future lifespan, show the unresolved dependency rather than making the sample appear conclusively cheaper. The fleet can still decide that the candidate merits further evaluation without claiming a completed economic case.
For a production blade enquiry, provide the approved candidate configuration and intended order scope so the supplier can quote something genuinely comparable. Keep any new commercial commitment within the responsible buyer's process. Close the cost review when ordinary supply terms are sufficiently defined and the trial's technical findings remain independent of the promotional arrangement. A useful report lets a reader answer two different questions: what the trial actually cost, and what the evidence suggests normal operation might cost under stated, reviewable assumptions.
