Clean invoice data into any ERP — new or legacy.
A modern cloud ERP, or a legacy system nobody else will touch? Harold reads, checks and matches your supplier invoices, then delivers either way — straight in via Zapier where it's supported, or as an import-ready file where it isn't.
How Harold gets data into your ERP
Train Harold on your suppliers
Upload a few invoices from each supplier. Harold learns the layout and your field mappings automatically — under 10 minutes per supplier.
Harold checks, fixes and matches
Each invoice is read, validated against your rules, and matched to your supplier and nominal codes — VAT checked, totals reconciled — before anything leaves.
Clean data lands in your ERP
Where your ERP has a Zapier app (WinMan, Xero, QuickBooks), Harold writes straight in. Where it doesn't (Sage 200, Pegasus, Syspro), Harold gives you an import-ready file that validates first time.
Why teams choose Harold
New or legacy, Harold connects
A cloud ERP with a Zapier app, or a legacy on-prem system that only takes a file import — Harold delivers to both. It's the layer that doesn't care how old your ERP is.
Clean data going in
Harold validates and matches before it outputs — supplier codes, nominal codes, VAT — so your ERP receives import-ready data, not raw OCR you have to fix afterwards.
Per-supplier intelligence
Harold builds a Supplier Profile for each vendor. The more invoices you process, the more accurate it gets — with no manual reconfiguration.
No rip-and-replace
Harold sits in front of whatever you run. Keep your ERP exactly as it is; Harold just feeds it clean data via the route it supports.
