What Billit does in ChatGPT
The Billit plugin connects ChatGPT to your Billit account so you can ask about your invoices, customers and suppliers in plain language. Billit is an e-invoicing platform and a certified Peppol Access Point, Peppol being the network businesses use to send electronic invoices to each other.
You can find sales and purchase documents, see which are overdue, and search by company, date, amount or text. It can add up totals per customer or supplier, pull contact details, VAT numbers and IBANs, search Belgium's public company register (CBE/KBO), and check whether a company can receive invoices over Peppol.
Access is read-only. No documents are created, changed or sent. You sign in with your own Billit login through OAuth and can revoke access whenever you like. If you run a multi-company account, you can work with any company you manage. Billit's help desk sits behind the Help menu at my.billit.eu.
