I'm here to help you today about having multiple markup accounts, 5247719909622897.
In QuickBooks Online, you can set up multiple accounts to track your income. For the markup account, I recommend consulting your accountant since you want to set up another one to track billable items.
Your accountant will provide specific instructions to ensure you have accurate records on your books.
I have setup an expense account and an income account in the products and service. The prior accountant set up a single markup account and I would like these markups to go the the income accounts set up in the individual product/service items. Is this possible?
