Automate your AP documents. Keep your ERP data clean.
Harold processes invoices, purchase orders, and goods receipt notes for UK manufacturers — trained per supplier, validated against your business rules, and routed to your ERP via Zapier.
How manufacturers use Harold
Invoice processing against PO references
Harold extracts invoice data and uses KeyMatch to validate supplier references against your purchase order list. Invoices without a matching PO reference are flagged before they reach your ERP — not after.
Goods receipt note automation
Harold processes GRNs from your suppliers with the same supplier-specific training model. Line item quantities, product codes, and delivery references are extracted and validated automatically.
GL code assignment by supplier and category
Harold's Rules Engine assigns GL codes based on supplier and document type. Direct materials, subcontractor costs, tooling — each category maps automatically to the right nominal code in your chart of accounts.
Multi-ERP support
Manufacturing businesses often run Sage 200, WinMan, or Pegasus alongside newer tools. Harold outputs via Zapier — system-agnostic by design, so it works with whatever ERP you run today.
