Document automation for accountants and bookkeepers

Stop keying invoices. Start adding value.

Harold processes client invoices automatically — trained per supplier, validated against your rules, and output to any accounting platform your clients use.

Built around how accounting practices actually work

Every client has different suppliers

Your clients don't share suppliers. The invoice formats you process for Client A are completely different from Client B. Harold builds per-supplier profiles that travel with each client — so the training you do once is never wasted.

Manual entry doesn't scale

A practice processing invoices for 20 clients manually is a practice that can't grow without hiring. Harold removes the per-invoice labour cost so your capacity grows without your headcount.

Client ERP variety

Your clients use Xero, Sage 50, QuickBooks, FreeAgent, and everything in between. Harold outputs via Zapier — so the same extraction workflow feeds any system your client uses.

Validation catches what manual entry misses

Harold's Rules Engine checks VAT arithmetic, mandatory fields, and supplier reference matching before data goes anywhere. Errors that would take hours to unpick at month-end are caught at the point of processing.
