It is often surprising to calculate the true cost of a single invoice. In many UK manufacturing firms, processing a supplier invoice manually can cost upwards of £4 when you factor in data entry, approval chasing, and error correction. For a Hull and East Riding SME dealing with hundreds of suppliers, this is a significant and often invisible drain on profitability.
A manufacturing client we worked with once discovered they had accidentally paid a £15,000 supplier invoice twice. The first copy had arrived by post and was approved by the production manager; the second arrived via email and was processed by finance. Because they relied on disconnected systems and paper records, the duplication wasn’t spotted until the year-end audit. This wasn’t a failure of the staff, but a failure of a system that allowed “data visibility” to remain clouded.

By introducing AP automation through a platform like DocuWare, we help firms eliminate these manual touchpoints. The system uses AI-driven indexing to “read” invoices, automatically checking them against purchase orders and flagging discrepancies or duplicates before they ever reach the payment run. This reduces the cost of processing each document to less than £1, representing a massive return on investment for high-volume businesses.
Furthermore, with Making Tax Digital requirements becoming more stringent in April 2026, moving to a digital-first record-keeping system is no longer a luxury – it is a regulatory necessity. A modern DMS ensures that every financial transaction is backed by an immutable digital source document, making your quarterly submissions to HMRC a matter of clicks rather than a week of stressful preparation.
At McKinney Haarcourt, we create and collaborate with your team to redesign these workflows for maximum efficiency. We help you gain real-time visibility into your cash flow, knowing exactly where every invoice is in the approval chain at any given moment. Don’t let manual admin erode your margins any longer.
