There is a long list of rules and regulations that businesses should be aware of regarding ACH payments. When businesses do not comply with these rules, there are massive fines that can be enforced. It can also lead to ACH payments being voided, which translates into business ACH payments being voided. Here’s a look at several ACH payment rules businesses should know. Businesses Must Verify Their Account Information You should regularly check your business’ account information on ACH payment forms to ensure it is correct. You can take advantage of the ACH validation test tool to check account information. This test requires you to send a negative transaction to your bank to make sure your business’ account information is correct. You can also use a third-party validation tool. If preferred, you can issue micro-deposits or use a customer sign-in tool to check account information. The purpose of micro-deposits is to ensure the payer is the owner of the provided account information. The micro-deposit workflow involves providing your bank account and routing number. You may have to provide the name of your bank as well. An ACH operator can send a request to the Automated Clearing House for micro-deposits to be deposited into your account. Once you verify them, the funds will then be deducted. Micro-deposits usually range anywhere from one to 50 cents.
