If you have successfully set up your online store, you can start selling your goods immediately with offline invoices. However, if you believe that your store will generate over 1000 EUR of revenue per month, we highly recommend adding bank links or credit card payment opportunities.
Before adding additional payment methods, make sure that:
you have registered the domain under which you will start managing your online store;
To add payment methods, open Store > Settings > Payments. You can see that you already have one payment method – Offline – which, as the name suggests, is for offline payments and doesn't require further setting up. Click on Add payment provider to see a list of payment channels that you can set up on your store.
