Invoice Generator
Open Source Invoicing
A self-hosted Django application for creating professional invoices, tracking payments, and generating PDFs. Built for developers, freelancers, and anyone who wants full control over their invoicing. Perfect for UK sole traders—or adapt it for anywhere.
Your invoices. Your server. Your rules.
Invoice Generator is a Django-based invoicing application you host yourself. No subscriptions, no third-party access to your client data, no vendor lock-in. Clone the repo, spin up Docker, and you're running.
Built for UK sole traders with UK tax year tracking (April to April), professional PDF generation, and recurring invoice support. Everything you need to bill clients and track payments.
Whether you're a developer invoicing consulting clients, a freelancer managing multiple projects, or a student learning Django—Invoice Generator is yours to run, modify, and extend.

Built For People Who Can Self-Host

What You Get
Professional PDF Invoices
Generate branded PDFs with your logo, bank details, payment links, and custom footer. Ready to send to clients.
UK Tax Year Tracking
Invoices auto-sort into April-to-April tax years. Switch between years and see revenue totals at a glance.
Recurring Invoices
Set up weekly, monthly, quarterly, or yearly templates. Generate invoices with one click for regular clients.
Payment Integration
Add Stripe or PayPal payment links to invoices. Clients can pay online directly from the PDF.
Why Not Just Use a Template?
You could. Many people create invoices in Word or Google Docs. But templates don't track payments, manage client history, or generate sequential invoice numbers. And cloud invoicing tools? They cost money every month and store your client data on someone else's servers.
Invoice Generator sits in the middle—more structured than templates, simpler than full accounting software, and entirely under your control.
Get Running in Minutes
git clone https://github.com/djangify/invoice-generator.git
cd invoice-generator
cp .env.example .env
docker compose up -d
Then open http://localhost:8000 and log in with your admin account.
Originally Built for UK Sole Traders
Invoice Generator follows UK tax year conventions with April-to-April tracking and VAT support. If you're self-employed in the UK, this gives you professional invoicing without the monthly fees of cloud services.
Not in the UK? The codebase is MIT licensed. Fork it and adapt the tax year logic and currency for your region.
