Dynamics AX 2012 R2 and R3 offer good built in functionality for credit card processing for sales orders.
The functionality uses MSPS gate way and can integrate with several of the popular processors including Bank of America and First Data. The service is provisioned thru your partner.
The great feature about the functionality is that it can authorized and then reauthorized for partial shipments automatically for remainder of the sales order amount without having to manually manage reauthorization. This reduces your risk of non-payment or NSF.
Another great feature is that if offers level 2 for most processors and in come cases level 3 credit card processing so you can drive for lower processing fees from your merchant service provider.
We have implement this functionality for our customers successfully. Please contact us if we can assist you.
