Practical notes for buyers
Cash flow is the quiet constraint behind supplier audit checklist: the cheapest option is rarely the one that frees the most working capital.
Where two suppliers look identical on price, supplier audit checklist is usually the variable that separates them over a full year.
Checklist
- Check carton quantities against the commercial invoice line by line.
- Log sell through by account for the first eight weeks.
- Keep certificates current and filed against the exact model name.
- Record the arrival condition with photographs on the day of delivery.
- Request batch photographs and a packing list prior to shipment.
- Review the reorder point after one full selling cycle.
Commercial terms
Payment history is the single most reliable route to better terms, more than total annual volume.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

|---|---|---|
| Carton (198 units) | Tier 1 | 30-45 days |
| Pallet (1038 units) | Tier 2 | 30-45 days |
| Container (11281 units) | Tier 3 | 7-12 days |
