GST invoices

GST invoices with a UPI QR, from one message

Tell Sochen who to bill and for what: it makes a GST tax invoice as a PDF, with CGST and SGST or IGST worked out, numbered for the financial year, and a UPI QR code for the exact amount. Free, and it reminds you when an invoice goes unpaid.

7 days of Plus for $5, then a monthly plan if you want one. Nothing renews on its own.

A Sochen GST tax invoice: business and customer details, items with HSN codes and GST, IGST total, amount in words and a UPI QR code

How it works

  1. 1

    Save your details once

    Business name, GSTIN, address, UPI ID and bank details, on the Business page or just by telling Sochen.
  2. 2

    Ask for the invoice

    “Invoice Rohan Traders, Pune, for 2 days of design at ₹8,000 a day, 18% GST, due in 7 days.”
  3. 3

    Send it, get paid

    Download the PDF and send it with the ready message. The customer scans the QR and pays the exact amount.

What you get

  • The GST done right

    CGST and SGST within your state, IGST to another, per line, rounded to the paise, with the round-off shown.
  • Everything on the page

    HSN or SAC codes, place of supply, the amount in words the Indian way (lakh, crore), your bank details and terms.
  • Paid, or a reminder

    Mark invoices paid in a tap. Overdue ones come up in Heads-ups, with a polite WhatsApp-ready reminder and the UPI link.
  • Not registered? Fine.

    No GSTIN, no GST: a clean plain invoice instead.

Questions

Is it free?+
Making an invoice costs no credits. Asking in a chat uses a little of the model, like any message, and new accounts start with a 7-day trial of Plus for $5.
How does it know CGST and SGST from IGST?+
From where you are and where the supply goes: within your state it charges CGST and SGST (half the rate each); to another state, IGST. Your state comes from your GSTIN, and the customer's from their GSTIN or the state you give.
What if I'm not registered for GST?+
Leave the GSTIN empty and Sochen makes a plain invoice with no GST, saying the seller isn't registered.
How are invoices numbered?+
In sequence for each financial year, like INV/2026-27/001, starting again on 1 April. You choose the prefix.
How does the UPI QR work?+
Save your UPI ID once and every invoice carries a QR for its exact amount, with the invoice number as the note. Your customer scans it with any UPI app and the money comes straight to you; Sochen never touches it.
Does it remind me when someone hasn't paid?+
Yes. Invoices are kept as unpaid until you mark them paid, and Heads-ups tells you when one is overdue, with a polite reminder ready to send.
