Supplier due diligence

How to Evaluate Machinery Suppliers

Machinery supplier evaluation should happen before a deposit. The goal is to verify specifications, proof of performance, spare parts, support capability, and payment risk.

Evaluation Framework

StepWhat to requestPass signal
Spec lockWritten model, dimensions, motor, controller, included accessoriesThe quote matches the invoice and manual.
Application proofVideo or sample test using your material, product, or containerThe supplier proves your use case, not a generic demo.
Parts planConsumables, wear parts, part numbers, and replacement lead timeCritical parts are available after purchase.
Support planInstall guide, training, warranty terms, response channelSupport is specific and documented.
Payment controlMilestones tied to test video, inspection, packing, and shipmentFinal payment follows evidence, not promises.

Documents Worth Requesting

  • Proforma invoice with exact configuration and included accessories.
  • Manual, wiring diagram, consumables list, and maintenance schedule.
  • Photos or video of the exact machine before packing.
  • Sample test evidence using your target material or product.
  • Warranty terms that clearly state exclusions, shipping cost, and support channel.

Risk Signals

  • The seller cannot explain why a machine fits your material, capacity, or budget.
  • The machine quote is unusually low but excludes tooling, compressor, chiller, software, or consumables.
  • The supplier refuses sample testing for a non-standard product.
  • Payment terms require most of the money before any proof of configuration or testing.
