After you approve a pay run, Pay the drivers offers the bank file: an ABA file in Australia, an ACH (NACHA) file in the United States, or a CSV spreadsheet (Canada and India, and available everywhere). Upload it to your bank's business banking to pay every driver at once.
Enter your company bank account in Settings, Pay settings: account name, BSB, account number, bank and APCA user ID for ABA; bank name, routing and account number and ACH company ID for ACH. Tick Add a balancing debit to the company account if your bank requires it.
