Is this service free?

Invobi offers both free and paid options:

  • Free tier — No account required. Generate up to 5 invoices per day using your own API key. You pay only for the AI API calls directly to your chosen provider (like Google Gemini or OpenAI).
  • Paid accounts — Create an account to unlock 500 invoices per day, save invoices to your dashboard, manage and track your invoices, and access the REST API for automation.

The core AI-powered invoice generation is always free — you just bring your own API key.

Are there any usage limits?

Yes, there are rate limits to ensure fair usage for everyone:

  • Guests (no account) — 5 invoices per 24-hour rolling window.
  • Registered users — 500 invoices per 24-hour rolling window, plus the ability to save and manage invoices.

The limits are based on a rolling window, so they reset gradually as time passes rather than all at once.

Is my data secure?

Your privacy and security are our top priority:

  • API keys are never stored — your key is only used for the single request to generate your invoice and is immediately discarded.
  • Free users: no data retention — your invoice is generated on-the-fly and sent directly to you. We don't keep copies.
  • Paid accounts: you're in control — we store your invoices for your convenience, but you can delete any or all of your data at any time from your account settings.

We believe in privacy by design — we collect only what's needed to provide the service, and you always have full control over your data.

How is my API key remembered?

When you check "Remember API key", your API key is stored in your browser's localStorage — a secure, local storage area that only this website can access.

Important points:

  • We never store your API key — it stays entirely in your browser, on your device.
  • We never send it to our servers — except when making the API call to generate your invoice, where it's used once and immediately discarded.
  • You're in control — uncheck the box anytime to remove it from your browser.

This is the same technology used by countless websites to remember your preferences. Your API key never leaves your device unless you explicitly generate an invoice.

We support multiple LLM providers. Choose the one that works best for you:
