About this template
What This Workflow Does
AP clerks open every vendor PDF, look up the PO and goods receipt in SAP Business One and key the invoice by hand, so backlogs and overpayments build up. This template reads new invoices from the Outlook AP inbox with OpenAI, finds the matching purchase order and GRPO, runs a 3-way check on vendor, price tolerance, quantity and duplicates, and posts the A/P invoice or holds it with an email to the vendor.
Key benefits
- Invoices read for you — OpenAI extracts vendor, invoice number, lines, tax and PO reference.
- PO and GRPO checked — Billed quantities are compared with what was received.
- Four outcomes — Approved, Approved with variance, Hold or Reject.
- Vendors told why — Held or rejected invoices trigger an email to the vendor.
Inside the flow
How the template works
A new email in the AP inbox starts the flow; OpenAI extracts the invoice data and appse ai fetches the PO and GRPO from SAP Business One. OpenAI runs the 3-way check, and the result decides whether the A/P invoice posts, posts with a variance, or is held or rejected with a vendor email.
Read it with OpenAI
OpenAI pulls the vendor, invoice number, line prices, tax and PO reference from the PDF or image.
Find the purchase order
If a PO number is present, the matching purchase order is fetched from SAP Business One; if not, Microsoft Teams is alerted.
Check the goods receipt
The matching GRPO is fetched to compare delivered and billed quantities.
Run the 3-way check
OpenAI checks vendor details, price tolerance, quantities and duplicates, and returns Approved, Approved with variance, Hold or Reject.
Post or hold
Approved invoices post as A/P invoices linked to the PO and GRPO; held or rejected ones trigger an email to the vendor.
Business Benefits
Post clean vendor invoices in SAP Business One and stop the rest before payment.
01

03

Price and quantity mismatches are stopped before posting.
04
Duplicate protection
Repeat invoice numbers are rejected before they reach the payment run.
05
Faster vendor resolution
Vendors get an email explaining the discrepancy instead of chasing AP.
