Built for invoices, not generic documents
Parseur is a general-purpose parser — useful, but you build every template yourself. Harold is purpose-built for accounts payable. It understands invoice structure, line items, VAT, and payment terms without manual template configuration.
Validation catches errors before your accounting system does
Harold's Rules Engine checks every extracted document — does VAT equal net × 0.2? Do line totals add up to the invoice total? Does the supplier name match your records? Parseur has no equivalent. You get raw data; Harold gives you verified data.
Supplier training improves accuracy over time
Harold learns each supplier's format individually. Upload examples once, and Harold extracts correctly for every future invoice from that supplier — even when layouts shift slightly between documents.
Priced for UK businesses in GBP
