If you know the cost of the subcontracted work in advance, you can set up
QuickBooks so that it automatically includes your markup when it enters the
rate for the subcontracted work on an invoice or sales receipt.
To do this task
Set up a service item to represent the subcontracted work.
In the Cost field, enter your cost, either as a flat amount or as an hourly
In the Sales Price field, enter the amount you would charge your customer
after having applied a markup to your cost.
QuickBooks then enters the sales price whenever you use the service item on
an invoice or sales receipt.
If you don't know your cost when you create the service item, leave the
cost and the sales price at $0.00. On an invoice or sales receipt, QuickBooks
enters the rate as $0.00. You can then edit the rate so that it includes your
cost plus your markup.
