How to invoice by talking to your AI

Most invoicing tools want you to stop what you're doing, open a tab, click through a form, and type out what you already know. Invoice Badger takes a different route: you just tell your AI what you did, and it keeps the invoice up to date for you.

What is MCP invoicing?

MCP (the Model Context Protocol) is an open standard that lets AI assistants like Claude talk to real tools. Invoice Badger runs an MCP server, so once you connect it, your AI can add clients, log hours, raise invoices and mark them paid on your behalf.

What it looks like in practice

After connecting Invoice Badger to Claude, you type things like:

• "Log 90 minutes on the Acme invoice for the API fixes" adds a line at Acme's hourly rate.
• "What's outstanding?" totals up your unpaid invoices.
• "Mark Acme's March invoice paid" does exactly that.

No forms, no tab-switching, no remembering which button raises a new invoice. You describe the work; the badger does the admin.

How to connect it

Create a free account, open your account page, and copy your MCP URL. Add it as a connector in Claude (or any MCP client), sign in with your Invoice Badger email, and the tools appear. From then on you can drive your whole invoicing from chat.

Prefer clicking?

There's also a plain, fast web dashboard for when you'd rather do it by hand: create invoices, add time or fixed-fee lines, and send a clean public link your client can view and print to PDF. Same data, two front doors.

Invoice Badger is free to start and built for freelancers, in GBP by default. Create your account and give the boring bit to a badger.
