GST invoices and payment reminders for shops, freelancers and small businesses in India
Track the Flow, Watch it Grow.
Make GST invoices, see who still owes you money, and send a WhatsApp reminder with the message already written.
Shops, studios and people who bill for their work.
The GintiFlow website and app, drawn with a demo business and sample figures.
A queue at the counter? Bill each customer in seconds and hand over a printed slip. Every bill lands in your GST figures.
Make the invoice, send it on WhatsApp, and your customer pays from the UPI QR printed on it. Mark it paid when the money arrives.
See who is late, and by how many days. One tap writes a polite WhatsApp reminder with the balance due. You press send.
Quote first. When the customer says yes, the quotation becomes an invoice with the same items and prices. Delivery challans work the same way.
Everything you need to get paid on time.
Quotations and delivery challans
Send a quotation with a date until which the price holds. When the customer agrees, turn it into an invoice in one tap, with the same items and prices.
Delivery challans work the same way for goods that leave before the bill does.
The month's GST figures for your CA
The GST tab adds up your invoices the way GSTR-1 asks for them. Add your purchase bills and it sets the GST you paid against the GST you collected.
Download it all as one spreadsheet for whoever files your return. GintiFlow does not file returns.
Also included
- E-way bill file. Fill a short form and get the file the e-way bill portal accepts for bulk upload.
- Saved items. Keep a price list so an invoice line fills in with one tap.
- Credit notes. Reduce or cancel an invoice you have already sent, and the GST figures follow.
- Up to three businesses. Switch between them from the same login, each with its own invoices and GSTIN.
- Monthly customers. Mark who pays every month and see who has been billed and who has paid.
- Reports. What you billed each month and to which customers, with a spreadsheet for your CA.
Simple to start, and your data stays yours.
- Your name on the invoice. No GintiFlow logo or footer on your PDFs, on any plan.
- No bank linking. Sign up with Google or your email. You type in only what you want on the invoice.
- Nothing to sell you. We don't offer loans, insurance or investment products, so the calculators show you the numbers and stop there.
- A person replies. Write to support@gintiflow.com and someone from the team answers.
