What it does
Invoices and estimates
Send estimates, and turn an accepted one into an invoice in one step. Number series can reset each year, month or financial year.
Nine currencies
Bill in INR, USD, EUR, GBP, AUD, CAD, SGD, JPY or AED. Each organization sets its own default currency.
GST and VAT
Tax rates follow your country. For Indian GST, the split between CGST and SGST or IGST comes from the place of supply.
PDFs and share links
Every invoice becomes a PDF with your logo and bank details. Email it, or send a link that works for 30 days without an account.
Payments
Record full or part payments. Invoices move to partly paid or paid on their own, and the dashboard shows what is still outstanding.
Your AI assistant
Connect Claude or another MCP client to ask about invoices, customers and outstanding payments. It signs in as you and can only read.
Two ways to use it
Use the hosted app
Sign up, set up your organization and send your first invoice. It's free, and we keep it running and up to date.
Run it yourself
Clone the repository and start it with Docker. The MIT licence lets you use it, change it and run it for your own clients. The README walks through setup.
