Steps

Trigger: BILL 'New Bill'.
Add Formatter by Zapier to format the amount as currency and the due date as a readable date.
Action: Slack 'Send Channel Message' to #ap-approvals with vendor, amount, due date, and a link to the bill.
Optional: add a Filter so only bills over a set amount ping the channel.

Keep a human check here: Low risk

Approvals still happen inside BILL. Slack is only the alert, so nobody can approve a payment from a chat message.

Node and module names match Zapier's docs as of Oct 2026. Apps rename triggers and actions sometimes, so check yours in the editor. Try it with test data or a sandbox company first.
