To explain,  I am accounting only,  I am in no way involved in inventory management or entries.   Newly thrown into managing the P&L, Trial balance, etc.   When pulling information to close out the 2019 year.  The COG's account was greatly misconstrued.   Upon review,  i found that build assemblies are crediting the COGS account and skewing the numbers.   My accountant is currently at a loss and I have spent countless hours trying to hunt this down.  A little more info is that the current Purchasing manager doing this is completing unaware of what could be throwing these numbers off or what she could be doing to cause this.  I am unable to create an JE as I have no idea where this dollar amount is coming from.  I am talking hundreds of thousands of dollars.  Upon deeper review, i found that in the entry of the actual items entries, I found the sales acct and the expense account are BOTH PURCHASE COST OF GOODS.  This is a years worth of item entries.  To fix this would be hours and hours of entries in single user mode that I do not have. I wanted to simply do a JE to adjust Debiting the COGs account and crediting another account. However, i do not know what account to put this to.  The actual invoice billed out correctly to sales.  I cannot put to sales because this number would double.   Please forgive,  I have spend most of the day on this and I am just over it at the moment.
