Contact
The fastest way to reach us is email: hello@duesetu.com. We usually reply within two business days. DueSetu is built by DueSetu in India. It is not a government portal and it is not affiliated with the GST Network, NPCI or any bank.
What to put in the mail
For a bug, include the browser (Chrome, Samsung Internet, Safari), whether you were signed in as a shop owner or as a customer, and what you expected to happen. A screenshot of the screen, not of a UPI app, is enough. Do not send customer balances, GSTIN copies or Aadhaar photos. We do not need those to fix a button.
For billing, write the Google account you signed in with and whether the question is about the free GO ledger or the PRO invoices and receipts. For a first login that created a duplicate shop, say so in the subject line so we do not treat it as a feature request.
Play Store apps
Shop owners use Abhedyam Owner. Customers use Abhedyam Connect. Both talk to the same backend as this site. If a sale shows on the phone and not on the laptop, say which app version you have (the number under Settings) and we can tell whether it is a sync delay or a real miss.
Public calculators (GST, EMI, interest, late fee, invoice, receipt) run in the browser and never create a ticket on our side. If a number looks wrong, tell us the inputs you typed. We can replay the same arithmetic.
What we will not do over email
We cannot file your GST return, recover a UPI payment from a bank, or tell you which HSN code a product must use. Those answers belong with a practising accountant or the CBIC tariff. We also cannot see a customer's dues unless you are signed in as that shop's owner, and we will not reset a password by mail. Sign-in is Google or the mobile number already on the khata.
