Important note: If you do not already have customers in QuickBooks Online, enabling this option is recommended as it will help prevent naming conflicts for similar Customer/Vendor/Employees. However, if you already have accounts in QuickBooks Online, then this setting could create new accounts that would seemingly duplicate existing accounts; so, please verify your mapping configurations before batching. Also, please note Employees (Manage Members) are created as Vendors in QuickBooks Online.
Contacts
The Contacts tab stores information related to creating Customers/Vendors in QuickBooks Online
Append account name: If enabled, newly created Customer/Vendor/Employee account names will be created per the Customer Mapping section with Append Account Name Enabled, i.e. newly created Customer/Vendor/Employee account names will be appended to the QuickBooks Online Company Name. If disabled, newly created Customer/Vendor/Employee account names will be created per the Customer Mapping section with Append Account Name Disabled.
