Invoiso is a free, open-source billing app for businesses that need GST-ready PDF invoices, local data storage, and full offline operation — without a Zoho subscription or cloud account.
Zoho Invoice is a cloud-first product — it requires an internet connection and stores your data on Zoho's servers. Invoiso runs entirely on your desktop. All data stays on your device and nothing is sent to any server.
Zoho Invoice requires a paid plan for full access. Invoiso is free forever with no usage caps, no premium tier, and no invoice limits. Every feature is available from the first launch at zero cost.
Zoho Invoice has no Linux desktop app. Invoiso ships AppImage and DEB builds for Linux alongside Windows and macOS installers, making it the practical choice for desktop billing on any platform.
Invoiso is published on GitHub under the MIT licence. You can inspect the source code, self-host, or fork it. Zoho Invoice is a closed commercial product with no source access.
Invoiso embeds a scannable UPI QR code directly in PDF invoices for instant payment via GPay, PhonePe, or Paytm. This is built-in at no cost and does not require a payment gateway integration.
Invoiso supports GSTIN, HSN codes, per-item tax rates, and configurable tax settings out of the box. Generate compliant GST invoices for Indian businesses on the first launch.
