You should be on Shopify Plus to modify the Checkout in such way.
Topic summary
-
Goal: Offer an automatic 10% discount at checkout to customers who choose an online payment method instead of Cash on Delivery (COD).
-
Core question: How to enable a payment-method–based discount that applies only when “online payment” is selected during checkout.
-
Update/constraint: A respondent indicates this type of checkout modification requires Shopify Plus, which supports deeper checkout customization. This implies that applying conditional discounts at the checkout stage based on payment method is not available on standard Shopify plans.
-
Outcome: No step-by-step solution was provided beyond the requirement to be on Shopify Plus.
-
Open items: No alternatives or workarounds (e.g., apps or pre-checkout logic) were discussed for non-Plus stores. The request remains unresolved for merchants not on Shopify Plus.
