The Sales Payment Types Number setting is used internally to identify each Sales Payment Type. It is automatically assigned, sequentially, when new Sales Payment Types are added and must be a unique number. The Number setting may be changed, but only if the payment has never been used on a Sales Transaction.
Note: Sales Payment Type Number 2 is reserved for the Cash Payment Type and cannot be deleted.
Note/Reminder: Once the Payment Type has been used, do not change the Number.
