At a small freight factor, the same few people underwrite the client, verify the loads and approve the ACH. CarrierKYC's Verified Payee is built for that desk. Before you fund a new carrier, it checks that the person applying controls the carrier and that the bank account belongs to the carrier. Afterwards, it re-verifies every bank or remit-to change before the next payment goes out.
It's in early access, and pilots are open to small factors. It sits next to your back-office software and doesn't replace it. Founding pricing is a free 60-day pilot, then $399 a month with 20 verified onboardings included, $25 for each extra onboarding, and payee-change re-verifications included.
