Capturing service related costs

good day all

Scenario …

a Project with some tasks and time sheets capturing time spent on those tasks. Tasks relate
to a service rendered to the customer.

When you invoice your customer, I can see only the Debtors, Sales and bank accounts in GL.
The cost of the labor, as captured in the time-sheets, is not accounted for.

All costs reflect in the project cost.

Just wondering what other ways there are to get those labor reflected somewhere in the COA.

One way I found was to do a payroll-run ( create salary component, salary structure, payslip )
Just thought there may be a short-cut to this ?
