Temporarily Renaming Existing Accounts
In-help popup topic
Point of Sale requires that certain accounts be present in your QuickBooks software to successfully integrate the two programs. These accounts include Accounts Receivable, Accounts Payable, Cost of Goods Sold, Sales Tax Payable, Undeposited Funds, and Inventory Asset.
If you have created custom accounts in QuickBooks of the same types, you may find it easier to temporarily rename these accounts to the default names listed above to enable the initial connection. After the connection has been completed, you can change the names back to your custom names and then edit Point of Sale company preferences to map to those accounts instead.
