How to automate ap invoice approvals on Starch

AP invoice approval is the process of reviewing incoming vendor bills, confirming they match purchase orders or contracts, getting the right sign-off, and releasing payment. It sounds simple until you have forty vendors, a part-time bookkeeper, and a founder who's also the de facto CFO. Invoices sit in inboxes, approvals happen over Slack DMs with no paper trail, and you only find out something slipped when a vendor follows up or a duplicate payment clears your account.

What this looks like in practice depends on your setup — how many approvers you need, whether you're running on QuickBooks or NetSuite, how many invoices come in per week, and how much of the process lives in email versus your accounting system. The persona-specific pages below go into those details.

On Starch, the end state looks like this: new invoices trigger a review task automatically, approvers see exactly what needs sign-off and by when, and your transaction feed flags anything that hits your bank account before it's been reconciled against an approved bill. No chasing down approvals in Slack. No end-of-month surprise charges. The workflow runs in the background; what you get is a clean queue, a clear audit trail, and an alert when something looks off.
