What to agree with a supplier beyond unit price: payment terms, minimum orders, quality tolerances, lead-time commitments and the remedies that make them real.

Unit price is the term buyers negotiate hardest and the one that matters least over a full year. Payment terms, order flexibility and lead-time reliability move more cash than a couple of percent on price.
This checklist covers what to settle before the first purchase order.
Commercial terms
- Unit price with a stated validity period and a mechanism for raw material moves.
- Payment terms in days and the trigger event: order, shipment or receipt.
- Volume rebate structure with a defined measurement period and payment date.
- Currency of invoice and who carries exchange risk.
- Incoterm, explicitly, it decides who pays freight, insurance and clearance.
Order flexibility
- Minimum order quantity per SKU and per shipment; these are often different.
- Change window: how late an order can be amended and at what cost.
- Reorder lead time separate from first-order lead time.
- Capacity commitment for peak, agreed in advance of the season.
Quality and compliance
- Written specification per SKU including materials, dimensions and packaging.
- Acceptable quality tolerance and the inspection standard used.
- Who pays for inspection, and what happens to a failed lot.
- Certifications required by the destination market, with expiry dates tracked.
- Code of conduct acceptance and audit rights.
Reliability and remedies
A lead-time commitment with no consequence is a preference. Agree what happens when a shipment is late: air freight at supplier cost above a threshold, a discount, or the right to cancel without penalty.
| Failure | Typical remedy | Threshold to define |
|---|---|---|
| Late shipment | Supplier pays freight upgrade | Days late before it triggers |
| Short shipment | Credit plus priority on next run | Percentage tolerance |
| Quality failure | Replace or refund, supplier pays return | Inspection standard and sample size |
| Price increase mid-term | Notice period and right to requote | Notice in days |
Questions worth asking before signing
- Who else do you supply in this category and market?
- What share of your capacity would our volume represent?
- Where do your own raw materials come from, and what is their lead time?
- What was your on-time rate last year, and how do you measure it?
- What happens to our order if a larger customer increases theirs?
