Ask ten electricians how they charge and you will get ten opinions delivered like scripture. The hourly camp says flat-rate is a way to overcharge for a twenty-minute breaker swap. The flat-rate camp says hourly is a way to hand your best years back to the customer for free. The truth is that both are right about the jobs they are describing, and wrong about the jobs they are not. This is the working owner’s version of the math, sorted by the kind of work actually rolling across your schedule.
Hourly is the model you can always explain. The customer sees the clock, sees the rate, and nobody feels tricked. That is a real advantage on work where you genuinely do not know what you are walking into. The trouble is what hourly does to a defined job. You bill your time, which means you never get paid for your skill. The dead circuit you trace to a backstabbed connection in fifteen minutes bills as fifteen minutes, even though it took you a decade to find it that fast. The faster you get, the less you make on the same job. That is a strange thing to build a business on.
Flat-rate charges what the job is worth to the customer, not how long your particular Tuesday takes. A 200-amp panel upgrade is a set price installed, whether the tie-in goes clean or you spend an extra hour fighting the meter base. A Level 2 EV charger on a straightforward run is one number, quoted before you start. What the homeowner hears is certainty instead of an open meter, and certainty is what closes the sale. Your fast jobs finally pay like fast jobs, and your slow-by-bad-luck jobs are covered by the average.
Very few good electrical shops are purely one model. The ones that make money tend to split the work by how knowable it is, and they do it on purpose instead of by mood:
The move that makes the hybrid clean is converting the moment scope is known. You arrive hourly on a troubleshooting call, find the fault, and then hand over a flat number to actually fix it. The customer stops watching a meter the second there is a fixed price on the table, and that is usually where the ticket size grows.
Here is the part both camps agree on once the arguing stops. Flat-rate without a written price book is just guessing with a confident face, and it falls apart the day a second tech quotes the same panel swap $400 lower than you would have. Hourly without a book means re-deriving material pricing in a driveway on every call, which is how margin leaks. The book is the asset: your parts, your real cost, your sell price, and your standard jobs, written down once so the driveway is never where you do pricing math.
That is the whole reason we built FieldForge around a price book instead of a blank invoice. Your catalog lives in a simple sheet you control, and when a tech says out loud "installed a 60-amp EV charger, forty feet of ten-two, one hour labor," the invoice prices itself from your numbers. Same panel swap, same charger install, same number from every tech, every time, with no meter running and no napkin math in front of the customer. You can build the book once and produce a consistent flat-rate estimate in the time it used to take to write the address. Free to start.
If you want to go deeper, our guide on how to price electrical work walks through building the book itself, and the plumbing version of this same flat-rate versus hourly question is worth a read if you run mixed trades or sub work to a plumber. When you are ready to put a number on it, the pricing page lays out the plans, and you can rough out a clean invoice right now with the free invoice generator.
