Pro tip: check your vendor onboarding docs BEFORE you sign the contract, cost me 11 days
Last month we signed a new fulfillment vendor and I figured onboarding would take 2 or 3 days tops. It took 11 days because their W-9, insurance cert, and bank letter all had different legal names and nobody caught it until our AP team ran the first payment. I spent 4 days just emailing back and forth between their rep and our billing person trying to match up entity names in the system. Then our ops lead was out sick for a week so the whole approval chain stalled. We missed two client ship dates and ate about $2,400 in rush fees to make it right. Has anyone built a checklist for vendor docs that actually catches this stuff on day one?
