Questions

What shop owners ask us first.

Do I need a laptop, or does it work on my phone?

Works on any device with a browser: phone, tablet, laptop, POS terminal. We recommend a tablet for the best experience at the counter.

What if my internet goes down?

SmartBill is offline-first. Everything is stored on your device, so bills, products and customers stay available with the WiFi down, and it syncs to the cloud once you are back online.

Can I use it on more than one device?

Yes. Your access URL works on any device you open it on, and all of them share the same data through the cloud sync.

Do I need to install an app from Play Store?

No. SmartBill is a PWA. Open the URL once, tap Add to Home Screen, and it behaves like an installed app after that.

What about GST invoicing?

HSN codes, CGST/SGST split, and amount in words. Add your GSTIN in settings and every sale within your own state bills correctly. Interstate IGST is not supported yet.

How do I pay?

UPI or bank transfer. We share the payment details once your shop is onboarded. The first 5 days are free, with nothing paid upfront.
