FAQ

Frequently Asked Questions

Everything you need to know about Invoice.

Is Invoice really free?
Yes. Invoice is 100% free and open source under the MIT license. There are no hidden fees, no usage limits, and no premium tiers. You can use the hosted version at no cost or self-host on your own infrastructure.
Can I self-host Invoice on my own server?
Absolutely. Invoice is fully open source and self-hostable. Clone the GitHub repository, configure your environment variables, and deploy on any infrastructure that supports Node.js. The frontend deploys to Cloudflare Workers and the backend runs on Convex.
How do I share an invoice with my client?
Every invoice gets a unique shareable link. Copy the link and send it to your client via email, Slack, or any messaging platform. Your client can view the invoice in their browser without creating an account or signing up.
Does Invoice support PDF exports?
Yes. You can download any invoice as a professional PDF directly from the invoice detail page. PDFs include your branding, line items, totals, tax calculations, and payment details.
What currencies does Invoice support?
Invoice supports multiple currencies including USD, EUR, GBP, CAD, AUD, JPY, CHF, and INR. You can set a default currency in your business profile settings.
Is my data secure?
Invoice uses HTTPS encryption, secure authentication via Better Auth with session tokens, and all data is stored on Convex — a secure, real-time serverless database. Since Invoice is open source, you can audit the code yourself.
