You do great work.
Getting paid shouldn't be the hard part.
Most people who freelance or run an agency are great at the work itself. The billing part? That gets pushed to "I'll do it tomorrow" — until a client is three weeks late on a payment you forgot to send. AgentInvoice takes care of the whole thing.
You just wrapped a project.
Open your invoicing app. Fill in the client. Add line items. Set the due date. Hit send. Realize you forgot to add tax. Fix it. 15 minutes gone.
Tell Claude 'invoice Acme Corp for the branding project, $6,000, net 30.' It's sent. You're back to work in 30 seconds.
Someone's invoice is two weeks overdue.
Log in, find the invoice, manually send a follow-up email, feel awkward about it, put it off until it's been a month.
Ask 'what invoices are overdue?' Your AI tells you, and you say 'send reminders to all of them.' Done without the awkward energy.
You have a retainer client for $3,000/mo.
Remember to send the invoice every month. Forget in December. Try to send two invoices in January. Apologize.
Set up recurring billing once. It goes out automatically every month. You never think about it again.
How it works
Connect AgentInvoice to your AI
Works with Claude, ChatGPT, OpenClaw, and more. Claude users connect in about two minutes — no technical setup, just paste a URL and click authorize. Your AI gets access to your invoicing in one shot.
Tell it what to do
Add a client. Create an invoice. Send an estimate before a project starts. Set up monthly billing for a retainer. Your AI understands plain English — no special commands, no forms, no clicking around.
Get paid
Every invoice gets a clean, branded payment link — no client login, no extra steps. They click, they pay by card or bank transfer. You get notified. That's it.
Everything you need.
Nothing you don't.
AgentInvoice is built to do one thing — invoicing — really, really well. No accounting, no payroll, no bloat. Just a clean billing tool that your AI can run for you.
Send invoices in seconds
Create invoices with multiple line items, taxes, due dates, and notes. Your AI handles the math. Every invoice gets its own payment link, a PDF download, and an audit trail.
Estimates that close deals
Send a quote before you start. When the client says yes, convert it to an invoice in one command — all the line items carry over automatically. No double entry.
Recurring billing on autopilot
Got retainer clients? Set up a billing schedule once — weekly, monthly, quarterly, or custom. Invoices go out automatically. Enable auto-send and you never have to think about it.
Automatic reminders
Set reminder rules per invoice: a few days before it's due, the day of, and a nudge after. They send on their own. Your client gets reminded. You stay above the awkwardness.
A portal your clients will love
Every invoice has a shareable link — no login required. Clients who want to see their full history get a magic-link portal with everything in one clean view. No new accounts, no passwords.
Branded like your business
Upload your logo, pick your brand color, choose your invoice template. Classic, Modern, or Minimal. Your invoices look like you made them, not like you pulled them out of a form.
Know who owes you what
Dashboard shows outstanding balances, overdue invoices, and what's been paid this month. Or just ask your AI — "what's still unpaid?" gets you a straight answer.
Team access
Invite teammates to your account. Everyone sees the same clients and invoices. Good for small agencies where more than one person sends bills.
Getting paid is
the whole point.
Connect your Stripe account and every invoice becomes a live payment page. Clients pay by card, bank transfer, or digital wallet — right from the link you send them. Partial payments are tracked automatically. No chasing, no spreadsheets.

The secret behind all of this is that AgentInvoice is built to work natively with AI tools — Claude, ChatGPT, OpenClaw, and others. Not as a hack, not as a workaround. It was designed from day one so that any AI that supports MCP can plug in and take real actions. Connect once. From that point on, your AI has a fully working billing operation at its fingertips.

Any other MCP tool
One URL, one API key
Cursor, Windsurf, Claude Desktop. If it speaks MCP, it speaks AgentInvoice.
Built for developers too.
Under the hood: full REST API, OpenAPI spec, auto-generated TypeScript client, HMAC-signed webhooks, and per-user API keys. Every invoice event fires a webhook. The MCP server runs over SSE with OAuth 2.1 and API key auth. If you're building an agentic workflow and need a billing layer that actually works — this is it.

Frequently Asked Questions
Do I need to be technical to use this?
Not at all. If you can type a message to Claude, you can run your billing on AgentInvoice. The setup for Claude takes about two minutes and requires no coding or configuration files.
What if I want to use it without any AI tools?
That works too. The web app is clean and fast — you can create invoices, manage clients, and send everything directly without ever touching an AI tool. The AI integration is there when you want it, not required.
How does my client pay?
Every invoice has a unique shareable link. Your client clicks it, sees the invoice, and pays by card or bank transfer through Stripe. No account, no login, no friction.
Can I try it before paying?
Yes — the free plan is fully functional, not a trial. 10 invoices/month, 50 clients, full AI integration. You'll know within your first invoice whether it works for you.
Does this replace my accounting software?
No, and it's not trying to. AgentInvoice handles invoicing and client billing. Your accountant or QuickBooks handles the books. They play well together.
What if a client is late paying?
Set up reminder rules — before due, on due date, and after — and they fire automatically. Or just ask your AI: "remind everyone who hasn't paid this month." Both work.
