RE: Bank Charges at the time of Manual Payment Entry or Cash Receipt
Do you send the 1,200 to the Supplier and 25 to the Bank - Correct?
In this case I would do the Supplier payment and the payment for the bank charges as two separate transactions.
The accounting question you need to answer is do you make the 25 part of the cost of the item, or simply a bank charge as part of the cost of overall doing business? YOu will want to talk to the accountant for the company to get that advise.
As to preparing the payment. I would believe that since the invoice for the item was 1,200 in purchasing, then the payment (check / eft / bank draft / manual check) should also be for 1,200 and not make it more complicated.
Let me know if this makes sense in your business application and if needed we can provide more assistance.
