Key Result

10 days → 5 hours monthly invoicing

The Challenge

Three supplier formats. 10 days. Every single month.

GCO Fuels receives transaction data from three different fuel suppliers — each in a completely different format. Every month, reconciling this data into client invoices was taking 10 full days of manual work.

The process required someone to manually match transactions, convert formats, check for errors, and compile invoices one by one. It was consuming the team's time and creating significant risk of billing errors.

Rod Gabb, the Managing Director, was spending time inside the business doing manual data work rather than running and growing it.

The Solution

AI that reads, reconciles, and builds invoices automatically.

Multi-Format Data Ingestion

AI reads all three supplier transaction files regardless of format — no manual conversion, no template mapping, no human intervention.

Automated Reconciliation

Transactions matched, anomalies flagged, and discrepancies surfaced for review — before a single invoice goes out.

Invoice Generation

Consolidated invoices built per client automatically — with the correct pricing, the correct supplier data, and zero manual assembly.
