Tell us your GST scheme. That's all.
Two common GST schemes, in plain words. Pick the one your business is registered under.
Regular scheme
The standard way most businesses registerYou charge GST on your sales and can usually claim credit for the GST you pay on purchases.
- GST shown on every invoice
- IGST, or CGST and SGST, worked out per order
- Sales and GST data ready for your returns
Composition scheme
A simpler option for some smaller businessesYou pay tax at a fixed rate on your turnover and have fewer filings. The rules are different, including for selling online.
- Choose it during setup
- Change it in Settings if your registration changes
- Your sales records stay in one place

GST questions, answered
Can I sell on Submerce without a GSTIN?

Do I have to create invoices myself?
No. Submerce creates a GST-ready invoice for every order, using your business details and the order details.
What happens when a customer returns an order?
A credit note is issued against the original invoice. Your sales and GST reports reflect the return.
