Add your billing details

CartWhizz can't issue a tax invoice until these are complete. If they're missing, the page says We cannot invoice this store yet and lists what's needed.

1. Open Finance → Billing & Plans → Billing details.
2. Who we invoice: your legal business name exactly as registered (it's printed on every invoice), and the email for invoices and receipts. Leave the email empty to use the owner's email.
3. Your tax registration (GSTIN), if you have one.
4. Billing address: address, City, State and Country. The state decides how tax is split on your invoice, so it must match your registration.
5. Notes on invoices (optional): up to 4 lines, such as a purchase order number.
6. Click Save billing details. When it shows Complete — invoices can be issued to this store, you're done.

Once a tax registration is on file, contact CartWhizz support to change it.
