The basket problem
A supplier may allow a low total quantity while requiring minimums for each model or finish. Create one row per SKU and record color, material, dimensions, included parts and individual packing. Then total the rows to see whether the assortment actually meets the terms.
Use different specifications for different families
Fit and construction
Record circumference range, closure, panel structure, fabric and decoration method.
Length and material
Record dimensions, stated material, edge finish, hardware and compartments.
Frame details
Record dimensions, lens description, hinge and included case without making unsupported protection claims.
Size and finish
Record dimensions, stated base material, finish, clasp and individual packaging.
Build a mixed-SKU matrix
SKU A / black / 20 · SKU A / grey / 20 · SKU B / black / 30 · SKU C / silver / 30 · Total 100 · Confirm: minimum per SKU, per finish and total orderAsk whether substitution is allowed and how unavailable colors are handled. Do not let the total hide a model that fails its own minimum.
Small components need a parts check
List removable pieces, spare parts, closures, cases, pouches or cables that should be included. A product photo may show display props that are not part of the quoted unit. Confirm the packing list in words.
Packaging controls count and condition
For small accessories, individual bags, cards, inserts and compartmented cartons can prevent mixing and surface damage. Record units per inner pack and carton so quantity checks and freight estimates use the same configuration.
Check the pack-out against the order matrix
Before comparing the final quantity, ask for a carton or inner-pack list showing SKU, color and count. Match that list to the approved matrix rather than to the catalog cover. This catches substitutions, missing small parts and duplicated variants while the order can still be described clearly.
Choose a sampling method that matches the risk
Inspect every unit when a missing small component would make the item unusable, or agree on a documented sampling plan with the responsible supplier. This guide cannot set a universal inspection standard; the right depth depends on product, claim and consequence.
Avoid claim inflation
Do not turn a material label or supplier message into claims about authenticity, safety, durability or compliance. Ask the responsible party for specific documentation where a regulated use or market requires it, and obtain professional advice when necessary.
