Hello there, Smith.
I know how efficient it is to use your Automated Clearing House (ACH) when paying a vendor. Allow me to provide additional information to ensure a better understanding.
When paying a vendor in QuickBooks Online (QBO), you can use your ACH. However, you'll need a merchant service account since QBO lets you send your ACH bank payments quickly and easily. In addition, please know that QBO will charge a fee whenever there are transactions created.
For more detailed information on this topic, kindly refer to the material: QUICKBOOKS BILL PAY.
