Invoice Processing Automation
A manufacturing business was processing hundreds of thousands of supplier invoices annually — a slow, labour-intensive, and error-prone process. We built an AI extraction and workflow automation system with full ERP integration.
The Challenge
The client's accounts payable team was manually keying data from supplier invoices into their ERP system — a process that was slow, costly, and prone to errors. With invoice volumes growing year on year, scaling the team was not a viable path. They needed an automated system that could handle varied invoice formats, match against purchase orders, route exceptions for review, and post validated invoices directly to the ERP.
Our Solution
We designed and built an end-to-end intelligent document processing pipeline. AI models extract structured data from any invoice format — PDFs, scanned images, and email attachments. The system validates extracted data against PO records, flags discrepancies, routes exceptions to the appropriate reviewer, and posts approved invoices to the ERP via REST API. The entire workflow is logged with a full audit trail.
Solution Highlights
- AI-powered extraction from any invoice format — PDFs, images, email attachments
- Automatic PO matching and 3-way validation (PO, receipt, invoice)
- Approval routing by value threshold and vendor rules
- ERP integration via REST API with error handling and retry logic
- Exception queue with human review workflow and resubmission
- Full audit trail for every transaction
Results
Processing cycle time reduced significantly. Near-elimination of manual data entry for standard invoices. Documented annual cost savings against previous headcount requirements. The system handles exceptions intelligently, routing only genuinely ambiguous cases to human review — reducing reviewer workload to a fraction of the original volume.
