01Business and payment identity
Record the legal business name, trading name, address, website, business email, invoicing entity and payment recipient. Investigate unexplained differences before payment. A document is useful only when its issuer, scope, date and connection to the transaction are clear.
02Exact product and claim match
Tie photographs, specifications, test reports, certificates, packaging and sample results to one product reference and variation. Note model, material, color, dimensions or configuration only when the evidence supports them. Similar-looking products are not interchangeable evidence.
03Quotation completeness
Check product reference, quantity, unit basis, packaging, setup, sample, inspection, payment, preparation time, quote validity and shipping scope. Separate included, excluded and unknown costs. A clean comparison requires the same commercial question for every supplier.
04Sample and acceptance record
Write the sample version, date, reviewer and intended retail use. Record observable results and any failed acceptance point. Keep reference images or measurements where appropriate. Do not replace category-specific testing or professional review with a visual inspection.
05Quality and change control
Ask how the approved reference is carried into the order, how substitutions are handled and which inspection or packing records will exist before dispatch. Require written approval for changes to product, materials, components, color, branding, packaging or quantity mix.
06Lead time and delivery ownership
Separate preparation, packing, dispatch, freight, customs and final delivery. Record which party owns each stage and which dates are estimates. Confirm the event that starts preparation and the update process when a date or route changes.
07Communication and issue handling
Review whether answers are complete, consistent and linked to the written reference. Ask how shortages, defects, transit damage or document corrections are reported. A clear escalation path matters more than a promise that problems never happen.
08Repeat-order and exit fit
Confirm how product versions, prior approvals, pricing and packaging are revalidated for a reorder. Record which performance facts will be reviewed after the first purchase. Keep an alternative plan when the product, evidence, cost or timing no longer meets the business need.
