Set up your GST and business details

Where it lives

Settings → Business & branding. Everything on this page appears on the invoices and quotations you produce, so it is worth getting right before you send the first one.

Add your GST number

Your GSTIN goes in one field on this page, and that single value drives the rest: the tax split on every invoice, the GSTIN printed on the PDF, and the figures that reach your GSTR-1.

Enter it once. You do not re-enter it per invoice, and you never choose a tax type by hand.

Let your GSTIN fill in the rest

Type a valid GSTIN and Dukaaan looks it up and fills in the registered name and address for you. It is faster than typing them, and it means the details on your invoice match the details on the portal.

If the lookup is unavailable, the fields stay editable and you can type everything by hand. Nothing is blocked.

Your state decides the tax split

The state in your GSTIN is your place of supply. When you bill a customer in the same state, Dukaaan splits the tax into CGST and SGST; when you bill another state, it uses IGST.

This is why a customer's state matters as much as yours. Save it on the customer once and every future invoice gets the split right without you thinking about it.

Logo and bank details

Upload your logo on the same page and it appears on the PDF. Add your bank account or UPI details and they print in the payment section, so a customer paying you does not have to ask for them.

Dukaaan never sees or moves the money. Bank details on an invoice are text you are printing for your customer, nothing more.
