Set Loyalty Cashback Percentage (Marketing: Hub) to e.g. 5. From then on, every time a logged-in customer completes a paid order, Sprwt adds that percentage of the order subtotal to their digital wallet with the description "Cashback #ORDER – 5%". Customers can spend the balance on later orders. The customer-facing Earn Rewards page explains it as "For every $1 you spend you receive a X% back" under Cashback Loyalty Rewards Program. Leave the setting empty or 0 to disable cashback.
