Error Syncing Invoice: Transaction with inventory products can't be dated earlier than the Inventory start date of the product.
Fixing inventory sync errors in QuickBooks Online by adjusting inventory start dates.
In QBO, there is a date attached to an inventory item as a 'start date '; you cannot use an inventory item before that start date. If we add inventory into the system, we do it as of the invoices on or after that date.
To fix this, the user needs to edit the inventory item in QBO and back up the start date to before the invoice date.
