If you choose MBWAY, Credit Card or ATM payments, there is an additional cost from the entities that manage those services.
The value is explained in the payment information page and varies in function of the contribution amount.
Because BoaBoa only charges a success fee to the project owners, we cannot cover these additional costs for all payments. Hence, the payment fees are passed to each and every backer.
For amounts equal or greater than 50 euros, where those payment fees are more meaningful, we also allow (wire) bank transfers.
Because the validation of each receipt with the bank statements is a manual and time-consuming process, this option is only available above that threshold.
