ACH uses a formula to calculate the amount of the payment. The order of payment is taken into consideration. Each business has different set-up fees so be sure to check with your provider to see what the maximum allowable number of ACH payments they allow is.

ACH fees vary according to the size of the business. It is up to you to determine what will work best for your company.

Some businesses choose to pay a flat rate based on the business size. The fee could range from a few dollars to hundreds per month.

While other businesses decide on a predetermined ACH payment plan. Some businesses set up a predefined number of such payments per month in order to avoid any unnecessary surprises during the month.
