I think you failed to grasp my question.  I do not want to let them select,  I want to dictate which they can use such that when the Sales Receipt is processed they can ONLY choose what I offer them.

Specifically, I do NOT want to offer Credit Cards to most of my clients as they already pay by bank draft.  This would only increase my costs with no real benifit.

Please detail the process to set the payment options at the customer level as an admin task such that the acceptable options show when processing a Sales Receipt.

Also, if set at the Customer card level, can these be locked such that the Sales person can NOT override them when processing a document?
