To better understand which file is a better choice for you, here's how:
Bank File (FAST)
Shows the breakdown of all employees' salaries in the bank statement, which could be a potential confidentiality issue.
FAST essentially allows you to transfer funds between banks instantly. However, each transaction for FAST payment is charged a more expensive rate compared to GIRO.
Not SAL coded.
Bank File (GIRO)
The preferred option because it displays 1 transaction line only in the bank statement for the whole batch payment.
SAL coded by default.
Hope this helps you to make a more informed decision π
