You’re a freelancer, not a finance department.
- FreshBooks wants $19 a month.
- Zoho wants you to learn Zoho.
- Stripe wants 0.4% of every invoice, forever.
- Google Docs wants you to realign the totals column one more time.
All you need is
- An invoice that looks like you made it on purpose
- A link your client can open and pay from
- A record of who still owes you
That’s the whole product.
Three steps, then back to real work
No accounting jargon and no setup marathon. Sign up and send your first invoice in the same sitting.
- Step 1
Fill in the blanks.
Client, line items, due date. Your logo, your colors, your payment details. Saved for next time.
- Step 2
Send it in one click.
Email it with your business name on it and replies going straight to your inbox. Or share a link, or download the PDF.
- Step 3
Watch it get paid.
Sent, paid, overdue. Record partial payments, and a nudge button for the ones that go quiet.
Why this instead of the big ones
Built for how freelancers actually bill.
Hourly or fixed, partial payments and credit notes, recurring invoices for retainers. Bill in any currency, and set a tax rate per line, so GST, VAT and sales tax all work without a plugin.
Looks like you, not like software.
Every invoice is designed to be the nicest-looking document your client receives that month. Pick one of six templates, then add your logo and set your own colors.
Yours to keep.
Download any invoice as a PDF, any time. Self-host it from the repo if you'd rather. Your billing history shouldn't live inside someone's subscription.
Know who still owes you.
Sent, paid and overdue at a glance. Record partial payments, and nudge the invoices that go quiet in one click.

Questions, answered
Is it really one payment?
Yes. Lifetime is $29 once and you have Pro for as long as the product exists. If we ever added something that cost us real money per user, it would be an optional add-on, never a surprise bill.
Can my client pay directly from the invoice?
Add your bank details, PayPal email or UPI ID and they appear on every invoice, with a scannable QR code for UPI. Clients pay you directly and we don't take a cut.
Does it handle my country's taxes?
Set a tax rate on any line item, so GST, VAT and sales tax all work. Indian GST invoices also get their own template with your GSTIN and the tax breakdown.
What happens to my invoices if you shut down?
You can download any invoice as a PDF at any time, and the whole app is open source under the MIT license, so you could run it yourself tomorrow.
Why is it so cheap?
Because it does one thing, and because one person built it instead of a company with a sales team.
Can I email invoices to clients?
Yes, on Pro and Lifetime. Invoices go out with your business name on them, and when your client hits reply it lands in your inbox, not ours. Payment reminders are one click.
Can I turn a quotation into an invoice?
Yes. Once a client accepts a quotation, convert it to an invoice in one click. The client, line items and taxes carry over.
