> Matches vendor invoices against purchase orders and receipts in the ERP and drafts clarification emails for mismatches. An accounts payable reviewer resolves any exception it cannot match.

An AI workflow Blueprint — a documented use case for Finance in Manufacturing & Distribution. Complexity: Advanced. Deployment: HeyQuinn recommended.

## The problem

Accounts payable teams in manufacturing reconcile vendor invoices against purchase orders and goods receipts across separate ERP and procurement systems. Invoice formats vary by vendor, currency conversions introduce errors, and missing receipt records or pricing mismatches force staff into manual, line by line comparison.

- Invoice formats differ across vendors and defeat rule based automation
- Missing goods receipt notes stall matching until someone tracks them down
- Currency conversion and pricing errors require line item comparison against contracts
- Vendor clarification emails are drafted one at a time by hand
- Reconciliation backlogs delay month end close and vendor payment terms

## The solution

A reconciliation workflow reads incoming invoices, retrieves the matching purchase orders and receipts from the ERP, and applies contract terms to identify mismatches, while accounts payable staff resolve what it cannot match.

1. Parses inbound invoice documents from the shared inbox using OCR and text extraction
2. Retrieves the corresponding purchase order and goods receipt from SAP
3. Applies contract specific pricing and discount logic to check each line item
4. Identifies mismatches in price, quantity or missing receipt records
5. Drafts a clarification email to the vendor for unresolved discrepancies
6. Pushes matched and resolved entries back into SAP once confirmed

## Where people stay in control

- An accounts payable reviewer resolves any exception the workflow flags rather than processing every invoice
- Vendor clarification emails are drafted for review before staff decide whether to send them
- Only confirmed, matched entries are written back to the ERP

## Systems and data

The workflow reads invoice documents, purchase orders and goods receipt notes from SAP and Ariba, references contract clauses and vendor history, and writes reconciled entries back to SAP once matched.

- SAP
- Ariba

## Results

- Reconciliation cycle time reduced from 5 days to 5 hours in the documented deployment
- Error rates cut to under 1 percent in the documented deployment
- Manual staff involvement reduced by over 70 percent in the documented deployment

## Why HeyQuinn is recommended

The workflow coordinates several specialized agents for parsing, retrieval, mismatch analysis, communication and ERP updates, and touches financial and vendor contract data, which argues for HeyQuinn recommended deployment with monitoring and governance across the agent handoffs.

## Frequently asked questions

### Does AI post reconciled invoices without review?

No. Accounts payable staff review any invoice the workflow cannot confidently match, and only confirmed entries are written back to SAP.

### What happens when a goods receipt is missing?

The workflow flags the invoice as an exception for staff review rather than guessing at a match.

### Does it send emails to vendors automatically?

The workflow drafts the clarification email, and staff decide whether to send it.
