An ACH (stands for Automated Clearing House) transfer is the most common way to move money electronically from one bank account to another. Each time you schedule a non-wire transfer of funds from one bank account to another, you have initiated an ACH transfer.
Does it cost money to send ACH transfers?
No, it is free to transfer funds in-to and out-of Atmos. There are no limitations on the number of transactions you can process.
