Do I need an Invoice Generator account?

No. You can open a prefilled document without an account. If you're already signed in, it works there too.

Does the AI create the final invoice?

The AI fills out the document and gives you a link to open it in Invoice Generator. You review and edit it before finishing.

Does Invoice Generator have its own AI chatbot?

No new chatbot is required. You can use an AI assistant you already use, such as ChatGPT, Claude, Gemini, or Perplexity.

Can AI use information we've already discussed?

Yes. If the information is available in your conversation, ask your AI assistant to use it when preparing the document.

What if the AI doesn't know something?

It should leave unknown information blank rather than inventing it. You can fill in anything missing after opening Invoice Generator.

Can I create documents other than invoices?

Yes. Invoice Generator supports invoices, receipts, credit notes, quotes, estimates, pro forma invoices, purchase orders, account statements, and timesheets.

AI invoice generator

Invoice with AI

Tell your AI assistant what you're billing for—customer, work, rates, and due date. It can prepare the document and give you a link to open it, already filled out in Invoice Generator.

Grok

Your invoice

Describe what you're billing for

Share the basics with your AI assistant: who you're billing, the work or items, quantities or hours, your rate or price, when payment is due, and the currency.

If you're starting a new chat, the assistant will ask for anything that's missing.

Create an invoice for Acme for 12 hours of design work at $150 per hour. Make it due in 30 days. Use USD.

Your AI can turn those details into a prefilled Invoice Generator link.

Open the link, review the invoice, make any changes, and finish it in Invoice Generator.

How it works

From details to invoice

Tell your AI what to invoice

Describe the work, customer, pricing, and other details—or answer the questions your assistant asks. If you're already in a chat about the project, it can use that context too.
Open your invoice

Your AI creates a link to Invoice Generator using the information you provide. Open it and the invoice is already filled out.
Review and finish

Check the invoice, fill in anything that's missing, and make any changes you need. Then finish the invoice as you normally would in Invoice Generator.

No retyping into Invoice Generator—your assistant builds the first draft for you.

Or copy this prompt

I want to create an invoice in Invoice Generator. Read https://invoice-generator.com/ai.md and follow those instructions. Ask me for the details you need—such as who I'm billing, what work or items to include, quantities or hours, rates or prices, due date, and currency—then create a prefilled Invoice Generator link I can open and review.

Documents

More than invoices

Your AI assistant can prepare quotes, estimates, timesheets, receipts, credit notes, pro forma invoices, purchase orders, and account statements—not just invoices. Ask for the document type that matches what you need.

Review first

AI fills it out. You stay in control.

Your AI prepares the document using the information you provide.

You open it in Invoice Generator before anything happens.

Review the customer, line items, prices, dates, taxes, terms, and other details. Add anything that's missing or change anything that's wrong.

Your AI should leave information it doesn't know blank rather than guessing.

Accounts

Already have an Invoice Generator account?

Prefilled invoices work whether you're signed in or not.

If you're signed in, open the AI-generated link and continue using Invoice Generator normally.

There's nothing additional to connect or configure.

For builders

For AI assistants and developers

Invoice Generator publishes AI instructions specifically for AI assistants.

The OpenAPI specification defines the supported document fields and data structures.

Developers can also use the Invoice Generator API to generate documents programmatically.
