# AI Invoice Generator: How to Create Invoices From Your AI Assistant With Pocket Invoice By Tim · 21 Oct 2026 · Launch Spotlights > How to create invoices by chatting with an AI assistant: connect Pocket Invoice's free MCP server to Codex, Claude, ChatGPT or Cursor, what to ask, and what the assistant can and can't do with your invoices. --- # AI Invoice Generator: How to Create Invoices From Your AI Assistant With Pocket Invoice "AI invoice generator" can mean a web form that fills in an invoice for you. It can also mean an AI assistant connected to your invoicing account, which creates the invoice, numbers it, saves it and produces the PDF while you describe the work in plain English. [Pocket Invoice](https://www.freedominvoice.com/) supports both, and both are free. It's an invoicing app for freelancers, contractors and small businesses, available on the Web, iOS and Android. It also runs a free hosted MCP server that connects compatible AI assistants to your account. There's no paid tier. This guide covers how the AI connection works, how to set it up and what the assistant can and can't do. ![Pocket Invoice homepage with a Codex chat creating a $500 invoice as a PDF](https://res.cloudinary.com/dhdy0tbpt/image/upload/v1791658787/ShipBoost/screenshots/screenshot-89e24d52-1443-4134-a754-5146803d81c9.webp) ## Three ways to make an invoice with Pocket Invoice | | Web invoice generator | Pocket Invoice account (Web, iOS, Android) | AI assistant through MCP | |---|---|---|---| | Account needed | No registration | Yes | Yes, plus authorization | | How you create it | Fill in a form, preview, download the PDF | Create in the app from saved clients and items | Describe it in a chat | | Saved records | No; download the PDF to keep it | Yes | Yes, in the same account as the apps | | Cost | Free | Free | Pocket Invoice is free; your AI client may charge its own fees | The [web invoice generator](https://www.freedominvoice.com/tools/invoice-generator/) is the quickest way to make a single PDF: 21 designs, your logo, line items, tax, discount, shipping and a balance after partial payment. For ongoing billing you need an account, and that's also what the AI assistant works with. ![Pocket Invoice's free web invoice generator with template, logo and line-item fields](https://res.cloudinary.com/dhdy0tbpt/image/upload/v1791773541/ShipBoost/screenshots/screenshot-18a529b6-778a-4a64-81cc-16f1e3c834f5.webp) ## What MCP is MCP (Model Context Protocol) connects an AI assistant to outside tools. Pocket Invoice's MCP server lets your assistant work with your invoices and business records once you've signed in and approved access. Your company details and PDF template are already in the account, so you only tell the assistant what to bill. Here is what happens to a request like "Invoice Acme $500 for website design, due in 14 days": 1. You describe the work in the chat. 2. Pocket Invoice calculates the total, assigns the invoice number and saves the document to your account. 3. You open the Web preview or download the PDF. If sending is enabled, you confirm the recipient in the chat before anything goes out. ## How to connect your AI assistant The server details are the same for every client: - **Name:** Pocket Invoice - **Type:** Streamable HTTP - **Server URL:** `https://api.freedominvoice.com/mcp` Setup takes four steps: 1. **Sign in to Pocket Invoice**, or create an account on the Web. 2. **Add the MCP server** in your assistant, using the details above. 3. **Authorize the connection.** Sign in when prompted, choose one company and approve the permissions. 4. **Ask for your first invoice** in the chat. Where to add the server depends on the client. These are Pocket Invoice's own instructions from its [MCP setup page](https://www.freedominvoice.com/mcp): - **Codex:** Settings → MCP servers → Add server. Enter the details, save, then choose Authenticate. - **Claude:** Customize → Connectors → + → Add custom connector. Enter the name and server URL, then add and connect. - **ChatGPT:** enable Developer mode in Settings → Security and login, then open Plugins → + and enter the server URL. - **Cursor:** add a `pocket-invoice` entry with the server URL to `~/.cursor/mcp.json`, then restart Cursor. Pocket Invoice has tested the connection with Codex. Other assistants should work if they support remote MCP servers with Streamable HTTP and OAuth. ## What to ask There are no commands to memorize. Requests Pocket Invoice suggests: - "Invoice Acme $500 for website design, due in 14 days." - "Create an estimate for 10 hours of consulting at $80 an hour." - "Generate the PDF for invoice 1042." - "Which invoices still have an unpaid balance?" - "Show my sales for this month." - "Record a $200 payment received for invoice 1042." - "Add Jane Doe to my customers: jane@example.com." ## What the assistant can and can't do | It can | It can't | |---|---| | Draft invoices, estimates and purchase orders; edit, copy or convert existing ones | Send an email without your confirmation (sending starts disabled) | | Generate PDFs with your saved logo and design | Take a card payment, transfer funds or issue a refund | | Find and update clients, products and stock | Go beyond your account or team permissions | | Look up sales, outstanding balances and expenses for chosen dates | Act for a company you didn't authorize; you pick one company per connection | | Record a payment or deposit you've received, which updates the invoice balance | Move money: recording a payment doesn't charge or refund anyone | You can disconnect the assistant at any time from Pocket Invoice's AI connections settings. ## What's free without the AI ![Pocket Invoice invoice list showing status, email status and balance due](https://res.cloudinary.com/dhdy0tbpt/image/upload/v1791773541/ShipBoost/screenshots/screenshot-4fa4f113-035e-4c2b-b699-c2961e625094.webp) Pocket Invoice's [pricing page](https://www.freedominvoice.com/pricing/) lists every feature at $0, on the Web, iOS and Android: - Unlimited invoices, plus estimates, quotes, receipts, purchase orders and recurring documents - Custom PDF templates with your logo, and no Pocket Invoice watermark - Client management, items and inventory, expenses and projects - Payment records, reminders and business reports - Multiple companies in one account, with free team invitations and per-member permissions There are also free [business calculators](https://www.freedominvoice.com/tools/) for billable hours, job costs and profit margins. ## Who it suits, and who needs more Pocket Invoice fits freelancers, consultants, contractors and small studios whose routine is estimate, invoice and keeping track of what's owed, and who don't want a monthly invoicing bill for that. A contractor can invoice from a phone after a job. A consultant can turn an agreed scope into an estimate, then an invoice. Paid accounting suites can still be worth the money if you need broader accounting, payment processing or team workflows. Pocket Invoice records payments; it doesn't process them. If you need something the app doesn't do, the team takes feature requests directly and will discuss custom needs, though a request isn't a promise that it will be built. ## FAQ **Can ChatGPT or Claude create invoices?** Yes, if you connect them to an invoicing tool. With Pocket Invoice, you add its MCP server as a connector, authorize your account, then describe the invoice in the chat. Pocket Invoice has tested Codex; other assistants need Streamable HTTP and OAuth support. **Is the AI invoice generator free?** Pocket Invoice and its MCP server are free, with no paid tier. Your AI client may charge its own fees. **Can the AI send invoices without asking me?** No. Sending starts disabled, and each send needs your confirmation in the chat. **Do I need an account to make an invoice?** Not for a one-off PDF: the web invoice generator needs no registration. Saved records, the mobile apps and the AI connection need an account. **Can the assistant collect payment from my clients?** No. It can record a payment you've received and update the invoice balance, but it can't charge cards, transfer funds or issue refunds. ## Try it [Create a free invoice with Pocket Invoice](https://www.freedominvoice.com/), or follow the [MCP setup steps](https://www.freedominvoice.com/mcp) to connect your assistant.
