Charge flat rate for defined electrical jobs you can estimate well, hourly for troubleshooting and open-ended work, and a mix when a job has both. Whichever method you use, build the price from your own costs and billable hours, tell the customer how you charge before you start, and put permits, materials and labor on separate lines of the invoice.
Flat rate: a set price for a defined job
Flat rate works when you know the job well: swapping a fixture, adding an outlet, replacing a panel, installing an EV charger. Customers like the certainty, and you earn more when you work efficiently. The risk is underestimating. In older homes, walls and panels hide problems, so state in your terms that hidden conditions can change the price, and agree any change with the customer before doing the extra work.
Hourly: you bill the time worked
Hourly suits troubleshooting, where you can’t know the cause until you find it, and any job whose scope is open. It protects you from underestimating, but customers can’t predict the total, so give a rough range and agree an approval point if the job runs past it.
Mixed: flat for the known, hourly for the rest
A common approach is a flat price for the defined work, with hourly billing for troubleshooting or anything beyond the agreed list. State it in your quote, and use the same layout on the invoice.
Build it from your costs and billable hours
Add up your yearly costs: a wage you’re happy with, insurance, vehicle, tools, licensing, software and the taxes on your profit. Divide by the hours you can bill, which is fewer than the hours you work, since driving, quoting and buying materials aren’t billed. That’s the floor for your hourly rate, and flat prices should be built from the same number: your estimated hours times that rate, plus materials, plus your margin.

Common pricing mistakes
- •Flat-rate quotes with no clause for hidden conditions.
- •Counting only the hours on site and forgetting driving, quoting and materials runs.
- •Folding permit costs into labor so the customer can’t see what they were.
- •Never revisiting your rates as your costs change.
- •Sending the invoice days after the job.

Key Takeaways
Flat rate suits defined jobs you can estimate well, like replacing a panel or installing a fixture. Hourly suits troubleshooting and open-ended work. Many electricians use both, and tell the customer which applies before starting.
If you underestimate the job, you absorb the extra time. Hidden problems behind a wall or in an old panel are the usual cause. Include a clause that hidden conditions can change the price, and agree any change before doing the extra work.
Add up your yearly costs — wage, insurance, vehicle, tools, licensing and taxes — and divide by the hours you can actually bill, which is fewer than the hours you work once driving, quoting and buying materials are counted.
On their own lines, with the permit they belong to. If you pulled the permit for the customer, make clear the charge is a pass-through cost, not part of your labor.
Use a template that starts with labor and materials, add service-call and permit lines as needed, and send it the same day. The free LaborMate electrician invoice template is set up this way.
