Vendor emailed new bank details on their letterhead, invoice due Friday for $62k. AP wants to just update and pay. Stop them?
CLAUDE · WITH THIS SKILL Stop them - banking-detail changes via email are the number one AP fraud vector, and real letterhead means nothing when a mailbox is compromised; the $62k would clear into a mule account by Monday. Verification protocol: call the vendor at a number from YOUR master file or a prior contract - never from the email signature - and confirm with a known contact; genuine vendors expect this, fraudsters push urgency. Then look upstream: how did a change request reach payment without a hold flag? You need mandatory verification with dual sign-off on any bank change, plus a 3-day cooling period before first payment to new details. Want the change-verification checklist for the workflow?

What you're actually buying

Reads incoming invoices from PDF or email, extracts vendor, amount, and line items, matches them against the purchase order, prepares the journal entry, and flags duplicate or suspicious invoices before they get paid — the full AP cycle, not just data entry.

Saves 8-12 hours a week of an AP clerk's time on a mid-volume invoice load, and closes the gap where duplicate payments slip through.

Compatible with: QuickBooks, Xero, Excel. For a QuickBooks-native AP workflow specifically, see the QuickBooks AP Automation skill.

  • How is this different from QuickBooks AP Automation? This is platform-agnostic and covers the full read → match → post → flag cycle; the QuickBooks skill is built specifically around QuickBooks' AP module.
  • Does it detect duplicate invoices? Yes, that's a core check before anything is queued for payment.
  • Does this work for a small business, not just an enterprise AP team? Yes — it's sized for a single owner-operator handling AP alongside everything else, not just a dedicated AP department. No enterprise ERP integration required.

Questions about this product

How do I install it?+

Download the file, paste its full contents into your AI's custom instructions, project instructions, or system prompt field. Takes under 2 minutes.

Is this a course or a tool?+

It's a tool - a structured expert persona and workflow, not a video course. You use it immediately by pasting it into your AI chat.

Why does Petra always verify a vendor banking-detail change by phone?+

Because a change request that arrives by email, however convincing, gets confirmed using a phone number already on file before the AP system's bank record is touched - the change made under deadline pressure is exactly the one that gets verified most carefully.
