Why isn't my Shopify local delivery option appearing at checkout?

Start with the cart and the customer address, because Shopify only shows local delivery when every physical item can be delivered from one location with enough stock, and the address is verified and inside that location’s delivery zone. Then check that local delivery is active for that location and that the order meets any minimum-price rule you set. One easy thing to miss: it won’t appear if the customer starts checkout with an accelerated option other than Shop Pay, and B2B checkouts don’t support it either. Try a normal checkout with a real in-zone address after checking those settings; that usually makes the missing condition obvious.
