LabourCalc will tell you exactly what your Overhead Recovery is, your Payroll Costs and therefore your true Labour Cost.
What about lost time? The difference between the hours you pay your employee versus the number of hours you bill out for that employee. LabourCalc works all of this out for you to ensure you make the best possible decision about your charge-out rates to maximise profitability.
