1. Quality and specification
The contract should state that every batch comes with a specification carrying the figures and the batch number. Without this clause, a quality claim turns into an argument about taste.
2. The batch replacement procedure
What happens when the figures deviate: the response time, who collects the goods, at whose expense, and what replaces them. The wording «as agreed between the parties» means «however we settle it once it is too late».
3. Deadlines and the delivery window
A regular schedule beats the phrase «within a reasonable time». If you have a production window, it belongs in the contract, not only in the email thread.
4. Price and how it is fixed
Define how long the price holds and how changes are announced. Fixing it for a month under contract is a working practice that makes the budget predictable.
5. Payment terms and the credit limit
Deferral, the limit, and how it is reviewed. It works best when the criteria are transparent and the customer can see their standing, rather than discovering it at the moment a shipment is refused.
We keep these five clauses in our standard contract — not out of love for paperwork, but because they remove 90% of future disputes.
