Bills that SOS Inventory creates in QuickBooks are generated from item receipts. Thus, it is important to ensure that all bills are successfully synced to QuickBooks and increase the asset account of inventory items and increase the expense account of expense items by the amount on the corresponding item receipt. To check the sync status of the bills created by SOS Inventory, go to the Bills list (Sync > Bills). View the Sync error column to see if any bills have a sync error. If you find any, you will want to re-sync that bill to QuickBooks after correcting the error. To do that, you will:
Once you have completed this process, check the Bills list again to ensure that the sync error is no longer present. Also, check QuickBooks to ensure the bill has posted.
These two situations can sometimes be difficult to recognize. Using the Reconcile item receipts report (Operations > Reports > Accounting > Reconcile item receipts) will help. Also, it might be useful to export item receipts from SOS Inventory and/or the asset and expense accounts used by items in SOS Inventory if it becomes really difficult to track down an issue in QuickBooks.
