To add a markup using the time/cost or reimbursable expenses in QuickBooks.
Note: QuickBooks fills in the Markup Amount or % field with the markup set in the Sales & Customers preferences. If you decide to change the markup here, it applies only to this invoice. You can enter the markup either as a flat amount or as a percentage. For example, you could enter 10.00 (which QuickBooks would interpret as ten dollars), or 10% (which QuickBooks would interpret as ten percent). If you enter a percentage, be sure to include the % sign.
For example, if an expense is $50.00 and you want to mark it up by $10.00, you would change the $50.00 amount to $60.00.
Effect on your accounts: When you use this method to mark up an expense, QuickBooks does not post the difference between the original amount and the edited amount to your markup account. Instead, the entire amount posts to the account you use to track income from that type of reimbursed expense. To track markup income separately, you must use the "Markup amount or %" field to apply a single markup to all the expenses you select.
You can't split an expense. If you reduce the amount of an expense, QuickBooks assumes that you do not intend to charge your customer for the balance. You will not see the balance the next time you open the Choose Billable Time and Costs window for the customer.
