Invoice Reader

Paste the text of an invoice. It returns the invoice number, issue and due dates in ISO form, seller, buyer, currency, every line item, subtotal, tax and total, and checks that the line items add up to the subtotal and the subtotal plus tax to the total. Anything missing is left empty and named in the notes rather than guessed.

No tools: text in, JSON out

Work order4 Nov 2026

Turns pasted invoice text into clean JSON: number, dates, seller, buyer, line items, tax and total, and flags any totals that do not add up.
