Billit

Billit is a global e-invoicing platform and certified Peppol Access Point.

This plugin gives ChatGPT and Codex secure, read-only access to your Billit account. You can ask questions about your invoices, customers, and suppliers in plain language. No documents are ever created, modified, or sent.

What you can do:

• Invoices and credit notes — Find sales and purchase documents, check payment status, identify overdue invoices, and search by counterparty, date, amount, or free text.

• Spending and revenue insights — Calculate totals per customer or supplier across your order history. For example: “How much did I spend per supplier this year?”

• Customers and suppliers — Retrieve contact details, addresses, VAT numbers, IBANs, and Peppol identifiers for parties in your account.

• Belgian company registry lookup — Search the public Crossroads Bank for Enterprises (CBE/KBO) by company name or VAT number to retrieve official company information.

• Peppol verification — Check whether a company can receive electronic invoices through the Peppol network and see which document types it supports.

Example prompts:

• “Show my unpaid invoices from the last quarter.”
• “How much did I spend per supplier this year?”
• “Can I send an e-invoice to Acme NV?”

Who it’s for:

Businesses, freelancers, and accountants using Billit for invoicing and Peppol e-invoicing. Multi-company accounts are fully supported, allowing you to work with any company you administer.

Authentication uses OAuth 2.0. You sign in using your own Billit credentials and can revoke access at any time. All access provided through this plugin is read-only.
