In Rapido 3.4 the user have to enter both billing and shipping address..
Please consider one of these options
UX guidelines (case A):
Let user enter a billing address.
Have a checkbox "Shipping address same as billing".
UX guidelines (case B):
Let user enter a shipping address.
Have a checkbox "Billing address same as shipping".
In case A, it seems that the primary view of the checkout workflow is to generate an invoice, whereas in case B the checkout process is seen as a step in the workflow to finally ship the actually product being ordered to the customer.
An example for case A is WooCommerce, an example for case B is Shopify. Amazon also seems to prefer case B.
