AI USE CASE
Supplier Invoice vs PO Reconciliation
Automatically match supplier invoices to purchase orders and flag price or quantity discrepancies.
What it is
This use case applies OCR and document AI to extract line items from supplier PDF invoices and match them against corresponding purchase orders in your accounting or ERP system. Discrepancies in price, quantity, or item codes are flagged for human review, eliminating manual cross-checking. The solution is low-risk to deploy, requiring no complex infrastructure beyond a basic ERP or accounting tool.
Data you need
Historical supplier invoices in PDF format and a corresponding log of purchase orders, either in an ERP, accounting software, or a structured spreadsheet.
Required systems
- erp
- accounting
Why it works
- Standardise the invoice intake process so all supplier PDFs arrive through a single email inbox or portal before processing.
- Ensure purchase orders are consistently recorded in the ERP or accounting software prior to goods receipt.
- Run a two-week parallel pilot comparing AI flags to manual checks to build team trust before full handover.
- Define clear escalation rules for flagged discrepancies so the AP team knows exactly what action to take.
How this goes wrong
- Invoice PDFs are scanned at low resolution or in inconsistent formats, causing OCR extraction errors that undermine match accuracy.
- Purchase orders are stored in spreadsheets or emails rather than a structured system, making automated matching unreliable.
- Staff bypass the tool and continue manual checks out of habit, meaning discrepancies are still caught late.
- The matching threshold is set too strict, generating excessive false-positive flags that overwhelm the AP team.
When NOT to do this
Avoid this if your company processes fewer than 30 invoices per month, the setup effort and licence cost will outweigh the time saved for very low invoice volumes.
