Transaction Splitting with Inventory Account

Hi there,

I imported all of my business's transactions into QB.

As a part of our business, we purchase a ton of random inventory from a host of suppliers. We manage several client online stores and sell this inventory on their behalf. At the end of each month, we invoice our clients for the COGS along with a labor fee and profit split.

My issue is this: The payments we receive are a combination of those elements so I need to split the payment transaction. I also need to credit our inventory account for the amount of COGS we invoice our clients, but I have to use a non-inventory account when transaction splitting. What is the work around for this?

Should I create a client COGS Revenue account, have the portion of the payment attributed to that, and then create a journal entry to COGS Expense account (and thus decrease the Inventory account by the amount of COGS invoiced to the client without affecting our P&L)? Or perhaps first JE our COGS Account for the inventory value on the invoice, and then attribute the correct portion of the payment to the COGS account to reduce it accordingly? Would this automatically reduce the Inventory Account?

I'd ideally like to make it as clear and simple as possible for my CPA when handing it off while limiting the amount of JEs to lessen potential errors.

Thank you so much for the help,

Jason
