Buyers often optimise the first order hard — lowest price, tightest terms — and then wonder why they are deprioritised when capacity gets scarce. The supplier made a rational judgement about which customers to protect.
What suppliers actually value
- Predictability. A smaller order every month beats a large one at random intervals.
- Payment that arrives when it was agreed to arrive, without a reminder.
- Specifications that do not change after tooling. Changes are expensive and they remember.
- Problems raised early and factually, rather than accumulated and delivered as a complaint.
The first problem is the real test
Something will go wrong on an early order. How you handle it teaches the supplier what kind of customer you are far more than any amount of relationship-building beforehand. Asking what caused it, before asking who pays for it, changes the entire shape of the following two years.
