Smart Service can send data over to the myriad of job costing features available in QuickBooks, but Smart Service itself cannot perform job costing for you. Smart Service creates job records in QuickBooks Desktop (or Sub-Customers in QuickBooks Online) so you have a convenient place to associate your estimates, sales orders, purchase orders, invoices, timesheet entries, and more in one convenient place for reporting.
Smart Service alone offers profitability reporting, but not job costing. When estimating profitability, Smart Service calculates the difference between the cost of the line items entered on the work order versus the prices entered on the work order. This results in a simple calculation of profit, but does not include the cost of labor, depreciation of assets, or the use of other job materials not accounted for in the job items tab.
