A coupon that appears as a product and turns into a payment method in the form of a deposit at checkout

We have the following task for Shopify (not Plus, but the basic version):


It is necessary to create a coupon that appears as a product. The customer, when purchasing, pays for example 100€ and should receive

a specified amount in their profile, for example 110€ as a payment method at checkout. That is, on the next order, this amount

should be displayed as a payment method without the need to enter an additional promo code. There should be 10

or more such coupon products, and the seller should be able to set the amount, for example, a 110 euro deposit and a client price of 100€, etc. Ideally, there should be sorting,

so that after some time, it is possible to export and see who has how much remaining. The client should be able to use this deposit for multiple orders,

not all at once. It is desirable to have some status for this client for sorting and for recognition in CRM.
