Most QuickBooks accounts already have login access to the online service center by default. If you have one of the accounts below, sign in to your online service center using the email address you provided at sign-up.
For other payments accounts an online service center (merchantcenter.intuit.com) username must be created manually using the email on the account.
Note: The email may take up to a couple hours to arrive.
NOTE: To combine payments accounts to view under one username see Combine payments accounts so they can be viewed under one login in the online service center
