I have here the complete steps on how to pay your vendor/contractor through Direct Deposit ( DD) in QuickBooks Online.
To start, you’ll need to set up your payroll bank account. DD requires a US bank account that is set up for ACH transactions. You may refer to this video tutorial on how to connect the bank with or without pay history: Connect your bank to Online Payroll.
Next is to turn on the DD for your vendor by clicking the Payroll or Workers and select Check it out above the list of your contractors. Then tap the Turn on the direct deposit button. See the sample screenshot below.
After that, let's enter your vendor's bank information in QuickBooks. You also have an option to invite them to enter their information for you to save time.
Here's how to add the account info:
Select Payroll, then Contractors.
Choose the vendor names, then select Bank account.
