Job costing in QuickBooks can also help you estimate more accurately. Estimating may be the most important—and most difficult—part of running a contractor business. But unless you compare your estimated costs to your actual costs after the work is complete, you have no way to know if you are estimating too high or low, and no way of improving your ability to estimate in the future. The QuickBooks job cost reports make it easy for you to compare your estimated costs to actual costs.

The level of detail in your Item list determines the level of detail in your job cost reports.
Quick Tip: To get a complete job cost picture, make sure to assign all your expenses to jobs. Also, select the appropriate job in the Customer:Job column whenever you enter a bill, check, or time sheet
Quick Tip: If you enter time and expenses on estimates and also on time sheets or bills, you will need to pick one to transfer to an invoice. For example, QuickBooks will not automatically correlate time from an estimate and the same time on a time sheet when adding it to an invoice. You have to do this manually.
