Set one rule: for each step of spend in an order, the customer earns a coupon code worth a set amount. When the order ships, the app creates the codes in Shopify as discount codes for that customer alone, one use each, and shows them on the order status page in a block you add with no code. Codes expire after the days you choose. A refund or cancellation voids the unused codes an order no longer earns. Expiry reminders go through your own Shopify Flow workflow and Shopify Messaging.
