Check a supplier yourself: guides to the official registers

The free path, honestly explained. Ten guides covering the registers, the cross-checks, and the fraud patterns.

Every check we run in a paid report can be done by hand against the official public sources, and these guides show exactly how, register by register. They are written for the moment that matters: you are about to send a first payment to a supplier you have never met.
