A low quote means little if the vendor can't hold tolerance at volume, document quality the way your industry requires, or hit the lead time they promised. Before you sign a purchase order, these five questions will tell you more than the price line ever will.
- 1. What certifications do you hold? ISO 9001, IATF 16949, RoHS compliance, and PPAP III capability each signal a different level of process control — ask which apply to your industry.
- 2. Can you support my full wire diameter and material range? A vendor that only covers part of your range today may become a bottleneck as your product line grows.
- 3. What's your realistic lead time, including tooling? Get the full timeline — not just production time, but tooling design and first-article approval as well.
- 4. Can you scale from prototype to volume production? Confirm the same facility that builds your prototype can also support your forecasted annual volume without re-tooling elsewhere.
- 5. Do you offer in-house finishing? Plating, heat treatment, and stress relieving done in-house reduce handoffs, lead time, and quality risk compared to outsourced finishing.
WHY THIS MATTERS
The cheapest quote that can't scale, can't certify, or can't finish in-house often ends up the most expensive one. Asking these questions upfront surfaces the gaps before they become your problem.
