About This Automation

Supplier invoice matching requires lining up an invoice against a purchase order and a goods receipt before payment can be approved. Doing this by hand across separate systems is slow and prone to missed discrepancies that surface only after payment.

The automated version extracts invoice data, checks it against purchase order and receipt records, and routes only real exceptions to a manager. Clean invoices post and file themselves, so approval turnaround shortens and fewer errors reach the ledger.

Key features:
Extracts invoice details automatically from incoming emails and attachments
Pulls matching purchase order and receipt records without manual lookup
Compares quantities, prices, and totals across all three documents
Escalates only genuine mismatches to a manager with variance detail attached
Posts approved invoices to the accounting system without re-keying
Files invoices and supporting documents automatically for audit readiness

How The Automation Works

The full workflow, from trigger to completion.

1. Invoice Receivedtrigger

Incoming supplier invoice email lands in the shared AP inbox and starts the workflow.

2. Extract Invoice Data

An extraction reads the PDF or email body and pulls vendor, PO number, line items, and totals.

3. Pull PO and Receipt

The matching purchase order and goods receipt records are retrieved automatically.

4. Match Invoice to PO and Receipt

A matching compares quantities, unit prices, and totals across all three documents.

5. Auto-Approve

When totals match within tolerance, the invoice is approved and posted for payment automatically.

6. Manager Reviews Discrepancy

When variances exceed tolerance, the AP manager gets a alert with a side-by-side comparison to approve or reject.

7. Archive Invoice and Notify Team

The approved invoice and supporting documents are archived and the AP team is notified.
