  • W-9 Agent emails vendors to request, collect and validate W-9 forms, and is on by default

Choosing between Stampli and BILL

Start with what you already run. If one documents an integration with your ledger and the other doesn’t, that usually settles it. Then compare the data-safety fields: ask whichever vendor shows unconfirmed for SOC 2 or training on customer data to put its answer in writing. Pricing is the last step, because published starting prices rarely match the plan a growing team ends up on.
