## The challenge

Finance teams manually cross-checked thousands of purchase orders, packing slips, and supplier invoices each month, creating massive invoice bottlenecks and human errors.

- Automate three-way matching at enterprise scale with line-item precision

- Isolate pricing variances and quantity discrepancies before payment release

- Integrate cleanly with legacy ERP systems like Oracle and SAP

## How we structured it

We designed an automated audit pipeline with human-in-the-loop exception handling:

Sync → Match → Resolve

### Sync

Stream purchase orders and invoices from ERPs and billing platforms.

### Match

Execute deterministic multi-variable validation rules across line items.

### Resolve

Route exceptions to accounting specialists with contextual root-cause data.

## What we built

### Three-way match automation

Continuous automated validation of invoices against purchase orders and receipts.

### Real-time exception queue

Prioritised dispute resolution queue with automated supplier communication workflows.

### ERP synchronisation engine

Bi-directional synchronisation with enterprise ledger and procurement infrastructure.

## The outcome

- **Transactions audited**: 140k+
- Transactions audited
- **Automated match rate**: 97.8%
- Automated match rate
- Drastic reduction in manual payment delays and audit preparation overhead

- Granular audit trails providing complete compliance assurance
