Does anyone know of an app that you can use to create and store spend accounts on shopify.
i.e. I'd like to give a group of users $350 apiece, I'd like them to be able to check out using that budget, i'd like them to pay by credit card if their purchase(s) exceed the $350. I'd like to add to the account when the period renews. If there is $15.00 left at point of renewal, new balnace will show $365.00.
