Zoho Books GL issue/question with Invoice from AP Bill

Zoho Books GL issue/question with Invoice from AP Bill

Hello All.
   We have been using Zoho books for the last several months.  One thing that we use extensively is during the bill entry in Accounts Payable we enter the customer in the line item section so when we bill the customer we can click on "bills" and it will bring it into the invoice with our markup, etc.  It works well.  Note that we do NOT use inventory and just use the "items" in Zoho books.  An example of the issue below is that on a specific item called Misc Hardware/Software we will have a Sales Account called "Hardware/Software Sales" and the purchasing side we have "Hardware/Software COGS". 

Now if we enter a regular invoice (without using the Bill option to pull from AP) and enter Misc Hardware/Software as the item the GL Account number will properly show up as "Hardware/Software Sales".  However, if we do the bill option where we pull in the the entry in AP the GL Account number shows up as "Hardware/Software COGS". 

We did not really notice this since we do not have the bulk edit option enabled but when we looked at our P&L it was not reflecting the sales properly at all.  Is this by design?  Where it is somehow "netting" the COGS since it is pulled from AP?  That does not seem logical at all to me.

I "Think" I can go into all our past invoices and go into Bulk Edit mode and change the account for those invoices to "Hardware/Software Sales" from "Hardware/Software COGS" but I did not want to do this if this is some sort Zoho designed thing.  And we went through all our settings and can not find any option to change this behavior. 

Am I losing it?  Is this because we are NOT using inventory?

Thanks for any feedback
Much appreciated
Mike
