Hi, Karen,

Total Costs Incurred reflects the total costs 'incurred' as in 'charged to' the job. Not costs paid.

If you are concerned that some costs are not showing, you need to check your Revenue/Expense method for the job. You may need to run Maintenance | Recognize Revenue & Expenses.

If you are concerned because you are in dispute with a vendor and don't want the costs incurred to include the costs for this manufacturer, you can enter a credit note into Payables and the CN will flow over to JobCost and reduce the total costs incurred for the job.
