Is there a free GST invoice app on mobile for small businesses in India?
Yes. Finocket is a GST invoicing and accounting app that runs on Android, iPhone and in a phone's browser. You add a customer and items, and it applies CGST + SGST or IGST from the place of supply and produces a PDF you can share on WhatsApp. For a one-person business the Solo plan is free until 31 Dec 2026, then ₹99/month. If you only need a single invoice, the free GST invoice generator on finocket.com makes a PDF with no sign-up.
What you can do for free
On the Solo plan, free until 31 Dec 2026, then ₹99/month, you can raise GST invoices from your phone, keep a customer list, record payments and see who owes you. Every new workspace can also switch on every module free for 30 days, so you can try GST returns and TDS before deciding on a plan.
- GST invoices with HSN/SAC codes and the tax split per line
- PDF invoices and receipts, shared on WhatsApp
- Customers, payments and outstanding balances
- Works as an app on Android and iPhone, and entries made with no signal are queued and synced
What needs a paid plan
GST return preparation (GSTR-1 and GSTR-3B), TDS, bank reconciliation, recurring invoices and inviting your CA start on the Starter plan. Finocket prepares GST return files for you or your CA to upload; it does not file returns on the GST portal itself.
When another app may fit better
If you mainly need a counter biller with barcode scanning for one shop, a dedicated billing app such as Vyapar or myBillBook may suit you. If your accountant already works in Zoho Books or Tally, staying close to their tool can be simpler. The comparison pages set out the differences.
