Hello, I would like to know if there is an application that allows you to accumulate prepaid credit that can be spent later slowly. The site in question will sell digital products (obtainable by download).
Example: the customer buys a prepaid credit: he pays € 100 and receives a credit of € 120 (with a bonus); an invoice is issued only for the actual amount paid (€ 100).
When the customer subsequently decides to download a product, the cost is deducted from his credit until it runs out.
At any time the customer can purchase another prepaid credit, the value of which will be added to the residual of the previous one.
