"I lost my laptop last year and thought I'd lost all my shop records. With JiiiMu's Google Drive backup, I installed it on a new PC and everything was back in minutes."
"Simple, fast billing and I don't need internet to use it. The backup running quietly in the background gives me real peace of mind."
"Free software that actually works well is rare. Waiting for the Hardware shop edition to launch so I can move my second store to JiiiMu too."
Yes. JiiiMu is free software. You can download, install and use it on your desktop PC without any license fee.
No. JiiiMu is 100% desktop-based and works fully offline for billing and inventory. Internet is only needed for Google Drive backup to sync in the background.
Once you connect your Gmail account, JiiiMu automatically backs up your data to your own Google Drive in real time, similar to how WhatsApp backs up chats.
Simply install JiiiMu on the new PC, sign in with the same Google account used before, and restore your data instantly from Google Drive.
JiiiMu is currently available for Retail & Wholesale businesses. Mobile Shop, Electric Shop, Hotel & Cafe, Pharmacy, Repair Shop, Hardware, and Education editions are coming soon.
