Overview

Harold is an AI-powered document automation tool designed to extract, validate, and fix data from documents like invoices, receipts, purchase orders, and statements before they enter downstream business systems. Unlike standard OCR tools that only extract text, Harold features a validation step with an advanced rules engine that recalculates totals, catches VAT mismatches, maps supplier aliases to internal IDs, and validates line items. The clean, import-ready data can then be seamlessly exported to various accounting platforms, legacy or new ERPs (such as Sage, WinMan, Pegasus, and Syspro), or automated workflows via Zapier.

How to use Harold?
Upload or email documents directly to your unique Harold inbox. The AI extracts headers, totals, line items, and references. It automatically runs validation checks and flags errors (e.g., VAT or total mismatches). Once verified, you can approve and export the clean data as CSV, Excel, or directly to your ERP/Zapier.
What makes Harold different from standard OCR and extraction tools?
Most OCR tools stop at extraction—they pull data off an invoice and hand it to you with potential mistakes. Harold goes further by recalculating totals, checking line items, matching your price list, flagging errors, and stopping bad data from entering your downstream systems.
Which ERP systems can Harold integrate with?
Harold supports both legacy and new ERP systems, such as Sage 200, WinMan, Pegasus Opera, and Syspro. You can connect it via Zapier or download a ready-to-import file tailored to your ERP's specific format.
