Is FixyBillBook really free?
Yes. Billing, stock, khata, reports and GST files are free, with no ads and no limit on bills or items. It is made by Fixholics as a free tool for small businesses.
Do I need internet?
No. Everything works offline and is saved on your device instantly. Internet is only used when you share on WhatsApp or open a link.
Where is my data stored? Is it safe?
Your data stays in a file on your own device — we never see it. Make a backup from Settings › Backup and keep it on Google Drive, iCloud, OneDrive or a pen drive. You can lock the app with a PIN or fingerprint.
Can I use it on my phone and my computer?
Yes, the same app runs on Windows, Mac, Android and iPhone. Move your data between them with a backup file. Live sync between devices is planned.
Does it work with my printer and barcode scanner?
Any printer your computer or phone can print to works, including 58 mm and 80 mm thermal printers. USB barcode scanners work like a keyboard, and phones can scan with the camera.
Can it make e-invoices and e-way bills?
It prepares the JSON files you upload on the e-invoice and e-way bill portals, and stores the IRN and e-way bill number on your bill.
I am not GST registered. Can I still use it?
Yes. Choose “Not registered” or “Composition” during setup and it makes bills of supply without GST.
