Rapid automation invoice solution achieves zero errors.

The challenge

A £750m construction company was processing supplier invoices through a largely manual workflow. The volume was high, the variability of invoice formats was higher, and the error rate created downstream rework that cost more than the original processing.

• High-volume supplier invoicing across construction sub-contractors and materials suppliers.
• Diverse invoice formats with no standard PO matching.
• Error rate generating rework and delayed payments.
• Finance team capacity stretched, with audit pressure on accuracy.

Our approach

We deployed an AI-led invoice automation capability built on the AI Factory operating model. Ingestion agents handle invoice extraction across PDF, scanned, and EDI formats. Analysis agents validate against PO and contract data. Senior finance ops staff handle the small percentage of exceptions that need human judgement.

The full deployment ran in under a month, including the change-management programme inside the finance team. Implementation investment was £25k. The saving recovered the implementation cost in eight weeks.

What we delivered

A production invoice automation capability with measured outcomes settled against the original investment case.

• Live invoice automation across the supplier base in under one month.
• 99%+ first-time invoice accuracy, with the remaining exceptions routed to senior reviewers.
• 3 full-time-equivalent finance roles redeployed to higher-value work.
• Implementation investment recovered in 8 weeks against the new run rate.
