BirdGPT

BirdGPT automatically processes invoices from your Gmail inbox and adds them to Moneybird. It uses GPT-4o to extract invoice details and can handle Dutch KVK and BTW numbers.

USE AT OWN RISK FOR NOW: I highly recommend testing the application with a separate Moneybird administration before using it with your actual administration. The application is still in development and may contain bugs. You can create a sandbox administration for free here.

• Automatically monitors Gmail for new invoices
• Extracts invoice details using GPT-4o
• Creates contacts and purchase invoices in Moneybird
• Handles Dutch KVK and BTW numbers
• Automatically matches correct tax rates
• OAuth authentication for Gmail
• Configurable email label and check interval
