Setting Up Supplier Verification: A Step-by-Step Guide for Buyers

Qualifying a new supplier is not a single check-the-box moment. It is a process with a clear order of steps, and skipping one usually shows up later as a delay or a compliance gap. Here is how to set up supplier verification properly, from the first prerequisite to what to do if something does not go through.

Before you start

Before you can verify a supplier, you need two things ready: the supplier's willingness to create an account, and clarity on what categories and regions they actually serve. Supplier verification only works if the underlying profile data is accurate, so it is worth confirming with the supplier upfront what legal entity they will be registering under.

Setup steps, in order

1. **Supplier creates an account.** The supplier sets up their own account rather than you entering their details on their behalf.

2. **Supplier completes a company profile.** This includes legal name, country, business type, registration number, categories served, and regions covered. Accuracy here matters — mismatches between the registration number and the legal name are a common source of delay.

3. **Supplier submits certifications.** Whatever certifications are relevant to the categories they serve should be uploaded at this stage.

4. **An administrator reviews the certifications.** This is the actual verification step. Nothing is marked verified until an administrator has looked at what was submitted.

Following this order matters because each step depends on the one before it. A profile submitted with incomplete category information will slow down certification review, since the administrator has less context to check against.

How to check it worked

Once an administrator has completed the review, the supplier's status should reflect that certifications were checked. If you are qualifying a new supplier, the simple test is: can you confirm that a named administrator reviewed the certifications on file, and does the profile's registration number match the supplier's legal registration in their stated country. If both are true, supplier verification has done its job.

When it does not go through

If certifications are missing, out of date, or do not match the categories the supplier says they serve, the review will stall. In that case, go back to the supplier and ask for updated documents rather than working around the gap. If the profile information itself looks wrong — a mismatched registration number, an unclear business type — that needs correcting before certifications are reviewed again, since verification is only as reliable as the profile behind it.

Supplier verification is one part of a broader qualification process; if you are still identifying which suppliers to bring into that process, our [supplier sourcing](/supplier-sourcing) page covers that earlier stage.
