Holdback is a percentage that can be configured in a user's ClickClaims record in order to create a secondary vendor bill - one for the holdback amount, and the other for the remainder.  The QuickBooks Web Connector service has an optional setting that allows for the holdback vendor bill to sync to QuickBooks.  This setting is not enabled by default and must be requested.  

Once the Holdback setting is enabled for the QuickBooks Web Connector service by E-Claim, a holdback expense Account must be created in QuickBooks (if synching vendor bill items as "Expenses") or a holdback expense Item must be created in QuickBooks (if synching vendor bill items as "Items") to which the holdback related vendor bill items are to be associated.
