Yes. The desktop app for Windows keeps everything on your own computer and bills perfectly with the internet unplugged — power cut, broadband down, it does not care. You only need a connection to check the licence now and then, to back up to Google Drive, or to file GST.

Yes. EasyBilling Cloud is the same software served over the internet, so you sign in from any computer, laptop or tablet with a browser. Shops often run the desktop app at the counter and the cloud for the owner at home.

Yes. Each shop has its own database file, and you can download it whenever you like from Settings → Backup. If you ever stop paying, you still have your data in a file you can open — nothing is held hostage.

It prepares your GSTR-1 and GSTR-3B for the month from your own bills, shows you what will be filed, and files it on the GST portal from inside the app. You still approve it with the OTP that comes to the registered mobile.

Yes, on the desktop app — 58mm and 80mm rolls over USB, network or serial, plus A4 invoices on an ordinary printer. In a browser you print through your browser’s own print dialog, which can also save the bill as a PDF.

In the cloud, yes — give each person their own login and decide which screens they see. On the desktop, each installed copy has its own data; the cloud is the version to use when the counter, the godown and the owner all need the same numbers.

Nothing is deleted. Your shop stops taking new bills until you pick a plan, and the moment you do, everything is exactly where you left it.

No. A plan covers the shop, not the number of people in it. Staff logins are part of the plan, not an extra line on the bill.
