Open your bank statement and highlight, underline or circle any ACH transactions. The bank should have "ACH" near the transaction. This ensures that any preferred stops are made by determining which merchants are billing directly and which are being paid through check, debit or cash.
Contact the merchant that is billing through ACH transactions. Tell the merchant to send paper bills and request a stop on the ACH transactions from the company. This prevents the merchant or group from billing the bank.
Contact the bank customer service. The numbers are usually available on the bank website. Request a stop on ACH transactions. This will put any new ACH bills on hold.
Fill out any paperwork required by the bank. Banks will differ in the paperwork required. The paperwork will usually need information such as account number, the ACH merchant and whether to stop future transactions or current and future transactions.
Pay any fees. The cost of fees will differ based on a few variables, such as putting a stop on current transactions or only future charges. Each bank will have different rates for stopping ACH transactions.
