QuickBooks merchant accounts that have been previously activated will prompt you to transfer service when linking to a new or different QuickBooks company file.
IMPORTANT: When linking a stand-alone GoPayment type payments account to another application (e.g. QuickBooks Desktop, Online or Point-of-Sale) a new connection is created which usually removes any previous inventory items in GoPayment. Be sure to document all your inventory items prior to linking the account to another application.
