Customers, products, invoices, payments, and reports, all in one place on your own computer — built for businesses that have outgrown creating one invoice at a time.
A desktop billing app that lives on your computer
Customers & products

Invoices & payments
Create invoices against your saved customers and products, and record payments against them as they come in.
Reports
See what's outstanding and what's been paid — aging, customer, product, and sales-summary reports.
Local backup
Back up and restore your data on your own terms, stored on your own computer.
Offline-first
Designed to work offline for normal day-to-day billing — no internet connection required just to create an invoice.
One-time license
A single lifetime license, active on one device at a time — no recurring subscription.
Works offline for day-to-day billing
Invoaro Billing is designed to work offline for normal day-to-day billing operations — creating invoices, recording payments, and running reports don't require an internet connection. Internet connectivity is required for online activation and licensing operations, such as activating your license on a device or recovering a lost license key.
One lifetime license, one active device
Lifetime license — ₹4,999.00
A single one-time payment. There's no subscription, and no recurring charge.
1 active device at a time
Your license can be active on one computer at a time. To move it, deactivate the current device from Settings → License, then activate it on the new computer.
Built for businesses that have outgrown one invoice at a time
If you're sending the occasional one-off invoice, the free invoice generator on this site works well on its own, with nothing to install. Invoaro Billing is for businesses that are doing this regularly enough to want saved customers and products, a running record of invoices and payments, and reports on what's outstanding — without needing an internet connection to do any of it day-to-day.
