Base Pay + Performance Plan

I"m trying to implement a base pay and performance bonus plan for my technicians. I want to keep it fair but still make some money. Here is a crude concept of my idea, but there still are alot of fuzzy areas



Base Pay (probably near or at minimum wage)



Performance based on gross profit of job (probably around 30-40% based on employee)



Here is my rough idea I may try out. Let me know your thoughts on this





Chunks of jobs come in and we will dispatch to the technician that is best at. Generally, jobs will be $150 - $ 5,000.00 for now. This is a service business so small service calls, service upgrades, ceiling fans, can lights, landscape lighting, emergency commercial troubleshoot, residential troubleshoot etc...



We send a chunck of jobs with all pertinant details to tech, they schedule, plan, design, pick up material (we pay on accounts), make customer happy, then they collect payment (check, cash, CC called into office). No pay, no bonus. :)



Gross Profit will be calculated like this



Revenue - 10% off the top then all expenses related to that job (gas, material, labor (at minimum)) will be subtracted. What's left is gross profit in this case or whatever that's called. They would take care of all facets of the paperwork, scheduling, warranty work etc.. and just turn papers in once a week or so. Papers will include job info and profit including all materials itemized per job.



Our first tech should make 1.25-2x what he normally makes but takes a huge load of work off us in the office in this method. I particularly like they schedule and line up their own jobs. This eliminates alot of problems.



Oh, if they don't get payment they dont get their bonus (is this legal ??)



How does this sound ? Any flaws or additions or subtractions to this needed ??
