A lot of trades businesses pay technicians a percentage of the ticket, or a flat SPIFF bonus every time they sell a membership or maintenance plan, sometimes layered with a tiered rate that increases once someone crosses a revenue threshold for the month. None of that is something Housecall Pro's payroll feature calculates on its own.
The usual fallback is manual: someone exports a job list, cross-references which jobs each technician closed, applies the company's actual commission rules by hand, and re-enters the totals into payroll. That's slow even for one location, and it gets genuinely error-prone the moment a business runs multiple sites with slightly different overtime or commission rules at each one.
