Labor, transport, discount, and previous due only print on the invoice when you enter an amount greater than zero.
Print Options
Tip: pair your receipt printer as a system printer on your phone/PC once, then it will appear in this print dialog like any other printer.
Bluetooth POS Printer
Not connected
Works on Chrome/Edge for Android, and desktop Chrome, with 2"/3" ESC/POS Bluetooth receipt printers. The page must be opened over HTTPS (not as a local file) for Bluetooth to be available. English/Latin text prints most reliably — many low-cost thermal printers cannot render Bengali or Hindi script.

Store Setup

Changes save automatically on this device.
Custom Charges
Add your own named charges (e.g. Packing Fee, Installation Charge). They'll appear as extra fields when creating an invoice, but only print on the invoice if you actually enter an amount greater than zero.

Product Catalog & Stock
Your Business Database
Every customer, phone number, address, product, stock level, invoice, and payment you enter is already saved automatically and permanently in a private local database on this device — even offline, with no internet needed. You can search past invoices in History, browse everyone in Customers, and track stock in the Product Catalog above.
What this device-local database can't do on its own is sync across multiple phones/computers or back itself up to the cloud automatically — that needs a backend server, which isn't part of this offline app. Use Export/Import Backup below to move your data between devices or keep an off-device copy.
Backup & Restore
All your data lives only on this device. Export a backup file regularly, and keep a copy somewhere safe (email, drive, another phone) in case this device is lost, reset, or the app data is cleared.
