In-person supplier verification in Mexico
A supplier profile can say anything. Before we introduce a shop, we visit it: we walk the floor, check the equipment list against real parts in production, confirm tolerances and capacity, and cross-reference its track record with other clients.
- What it is: an in-person visit and documented check of a shop before it is recommended to you.
- What it rules out: self-reported capability, staged photos and shops that can't hold your tolerance.
- Where: Querétaro and Nuevo León, Mexico.
- Cost: consulting engagements start at a fixed fee, discussed on the first call. Inquiring is free.
What we verify
- Equipment against real parts. We compare the equipment list with parts actually in production, not just a brochure.
- Tolerances, capacity and volume. Documented tolerances and real capacity are confirmed on site.
- Client references. We validate track record with the shop's other clients, not only the references it chooses to give.
- The people. We sit across the table from the owner and see how the shop responds when something goes wrong.
Problems this solves
- Marketplace and directory profiles are self-reported — no one has seen the shop floor.
- Engineering time is spent on shops that cannot hold the tolerance you need.
- The first purchase order with an unknown supplier carries the most risk.
How a verification works
- Intake call. A short conversation about your part, tolerances, certifications and volume.
- Visit. We go to the shop in person and document what we find.
- Decision. Only shops that pass are introduced to you.
- Introduction. You receive pre-verified shops matched to your specification, with one accountable point of contact on our side.
Verification lowers your risk; it does not replace your own incoming inspection. We still recommend a physical sample part before production — see quoting, sample and first order.
Information that speeds things up
Have these ready for the first call: the drawing with tolerances, material, estimated monthly volume, required certifications and your timeline. Not sure what to include? Use our RFQ checklist. For a deeper look at what a buyer should check, read how to vet a CNC supplier in Mexico.

Frequently asked questions
What does Arzen actually verify before recommending a supplier?
We visit the shop floor in person, confirm the equipment list against real parts in production, check documented tolerances and capacity, and cross-reference the shop's track record with its existing clients.
Do I need to visit the shop myself?
Not necessarily. What matters is that the visit is genuinely in person and documented. Many procurement teams use a partner who has already walked the floor, and still request a sample part.
Does verification guarantee quality?
No. It reduces risk by confirming capability and track record before an introduction. You should still inspect a sample part and incoming lots against your drawing.
How much does verification cost?
Consulting engagements start at a fixed fee, discussed on your initial call once we understand your part, tolerances and volume. There is no cost to submit an inquiry.
