I used the option transaction [credit] to the client as a bonus CashBack for the order.
I would like to get the opportunity to decide whether the customer will want to use the next time you collect the amount of the contract or it wants to collect on a larger sum.
Something like this works with reward points.
I would like to be able to limit the maximum amount to use the product at the rate of 50% of the product.
Has anyone seen something or someone I could use some help in modifying the code.
