Treat the questions below as supplier onboarding best practices: ask them before the first purchase order, and record every answer. They run from confirming who the supplier is to planning how you would leave.
Answers only help if they are recorded and compared. Scale the scrutiny to the risk: a stationery vendor needs a lighter review than the sole source of a key component. Put the early screening questions, such as identity, finances and sanctions, into supplier sourcing so unsuitable candidates drop out before negotiation. Let supplier onboarding software store the answers and documents, and let a supplier management platform compare them with later performance at review and renewal time. Onboarding decides whether supplier management starts on evidence or on guesswork.
