Firm pays for services for a customer. I enter them as a bill to a COGS account and mark them as billable to customer. Firm invoices customer. I expected the markup on the invoice to post to the corresponding income account I setup on the COA COGS account under "use for billable expense- enter income account." However it is posting to a seperate income account called "markup." What good is setting them up on the chart of accounts screen if the billable expense's markup does not post there? How do I get the markup on the items to post to the correct income account?
