FAQ

Frequently asked questions

Does it work offline?

Yes. Easy GST Billing is a Progressive Web App (PWA) — install it like a normal app and create invoices, record purchases and log payments with no internet at all. Data is stored on your device; you only need the internet to download and activate.

Does it work on mobile and tablet?

Yes. Easy GST Billing is fully mobile responsive and works on desktop, laptop, tablet, and smartphone. Install it as an app (PWA) on any device and create or share GST invoices on the go — all data still stays on that device.

Is it a one-time payment or a subscription?

It is a one-time lifetime license. Pay once and use it forever — no monthly fees, no recurring charges, and free minor updates are included.

Can I file GSTR-1?

Yes. Easy GST Billing exports the official GST offline-tool workbook — with b2b, b2cl, cdnr, sez, de, hsn and docs sheets — so you can upload it straight to the GST portal. Invoices carry the correct CGST/SGST/IGST breakup and HSN-wise summary.

Can I track what I owe suppliers?

Yes. Record supplier purchases, track your input GST / ITC, log part-payments, and generate a vendor statement of account for any date range as PDF or Excel.

How do I handle returns or rate corrections?

Raise a credit or debit note linked to the original invoice. Stock and GST are adjusted automatically, so your books and returns stay accurate.

Can I see a daily summary of money in and out?

Yes — the Daily Ledger (Day Book) groups every invoice, purchase, note and payment by day and shows Money In, Money Out and Net Cash. Export any period to PDF or Excel.

How is cash payment recorded?

You can optionally record cash by note denominations (how many ₹500, ₹200, ₹100…), which auto-total so your cash-in-hand reconciles at the end of the day.

Will I get a tax invoice for my purchase for input credit?

Yes. On purchase you receive a GST tax invoice (PDF) by email. If you provide your GSTIN at checkout, it is included on the invoice so you can claim input tax credit.

I lost my license key. How do I recover it?

Use the "Find my key" page. Enter your registered email, verify with the OTP we send, and your license key is shown instantly. You can also download your invoice from "My Invoice".

Is my business data safe?

Your billing data never leaves your device — it is not uploaded to any server. Only the details needed to process your purchase and provide support are collected.
