Choose a representative first project rather than a demonstration you would rarely make. Record supplier material identification, intended process, finished dimensions, shape and any coating or construction uncertainty. Keep suitability unresolved when identity or processing guidance is unclear.
Write observable acceptance criteria: required text stays readable, small details appear, pieces assemble as intended or decoration lands in the specified area. These are purchasing requirements, not claims that a machine achieves them. Separate essential outcomes from preferences you could change.
Request evidence that matches the workflow
Prepare a sample design without customer names or private artwork. Include intended physical size, material description, desired process and acceptance checklist. When reviewing a demonstration, record differences in stock, geometry, configuration and finish instead of assuming an attractive sample proves your project.
Carry a supported configuration into project-fit and room checks, then the setup budget. Keep a proof log with the question, evidence, outcome and limitation. A changed material, support, attachment or design size may require another check; preserve the conditions attached to the earlier result.
Turn the question into a decision record.
Evidence to collect before a purchase decision
Question
Evidence
Next action
Does the evidence match my stock?
Identified material and a demonstration describing its scope.
List differences and seek confirmation.
Does it meet my requirements?
A sample assessed against written acceptance criteria.
Track quote and used-machine evidence as confirmed, unresolved or conflicting. Create a printable buying record without a false readiness score.
