Create, send, and track invoices — and automate the painful part: chasing payments.
Forma Invoice is a self-hosted invoicing application that handles the full lifecycle of getting paid. Create professional invoices with line items, tax calculations, and payment terms, then download them as PDF or email them directly to clients. The built-in 6-stage automated reminder system emails clients before and after due dates — 1 day before, on the day, then 3, 7, and 14 days overdue — so you never have to manually follow up again. Generate one-click Stripe payment links so clients can pay online instantly; invoices are auto-marked as paid. Store client details, track invoice history per client, and archive inactive accounts. Pull revenue summaries, monthly breakdowns, tax-collected reports, and export everything as CSV for your accountant. Every user’s data is isolated to their own account.
