Bookkeeper for Electricians

How does money come into an electrical business?

Your money comes in three ways, and the books keep them apart because each one tells you something different about the job. Time and materials is billed hours plus the materials at a markup. Flat rate charges one fixed price for the finished job, usually quoted after a diagnostic that may carry its own fee. Value based pricing sets the price on what the outcome is worth to the customer, not what the hours add up to. You will mix all three in a single month.

The bigger split is the client type. Residential service calls turn fast and the cash comes back in days. Commercial installations and new construction carry bigger contracts, longer timelines, and almost always a deposit up front. That deposit is not income until the work that pays for it is done. It sits on your balance sheet as a liability with the customer attached. Booked that way, your monthly income shows three streams. Booked as one lump, you know the total and none of the truth.

Why am I busy but the bank never grows?

A calendar full of jobs and a bank that never grows is usually the same problem: labor and materials are not charged to the jobs that used them. The hours out of the truck, the wire, the conduit, the parts, they all add up and live in a large monthly summary. Your profit is in there, just mixed in with overhead, so 3% net looks like overhead that blesses the work. The jobs that made money don't stand out.

That is why a job number matters in this trade. Give every service call and install its own number, then run the labor hours, the materials, and the truck time against that number. The monthly close then gets you the most honest report: the job cost summary. Job costing is the biggest gap between electrical bookkeeping that just feels okay and bookkeeping that shows you what's working.

How do flat rate and time and materials fit in the books?

The books handle both the same way, but the risk is different. Flat rate is one fixed price, and that price is always quoted before you know how long the work actually takes. If the wall turns out to be old wire, or the panel fights the trim ring, the extra hours come out of your margin. Time and materials passes the extra hours to the customer, so the margin is safer and the estimate matters less.

The difference shows up in the job cost report. A flat rate job that lands 30 percent high in hours than you quoted is a pricing problem, not workmanship. A steady stream of time billables that pay the same way is a sign the rate is right. That visibility is what floats a job, and the books expose it.

What does my hourly rate really cover?

An hourly rate that only covers the hours you bill is a rate that's losing you money. The real rate has to carry your truck, your tools, your insurance, the office, and the cost of getting new leads, plus the crew's pay. Add the profit and the number on the invoice is all of that divided by the hours you can actually bill in a year.

Not every hour on the clock is billable. Drive time, truck restock, callbacks, and the blocks where no job is booked still cost you. If your rate only covers the hours you bill, the gaps between jobs come out of your bottom line. Job costing shows you how many hours each job truly takes so you can make sure the rate is not covering you.

What do I need to track separately?

Separate three things: job costs, overhead, and owner's expenses. Material and labor for a specific job go on that job. Overhead, the truck, the fuel, the rent, the insurance, is a monthly fixed cost, not anything one job eats. Your own personal spending or a truck the business bought for you, gets its own line, without turning a job's margins upside down.

And keep materials in two groups on the shelf for future work, and materials bought for a specific install. Uncarbed stock is an asset, not an expense yet. The panel you buy for a scheduled job is that job's cost. With the two groups together, a busy month looks profitable even when it isn't, or looks like a loss that is simply the cost of the next job. Separated, each job and your cash are both honest.

What net margin should I be aiming for?

A healthy electrical contractor nets around 10 percent of revenue after paying themselves and the crew, the trucks, the insurance, and the shop. Below that, the jobs are covering the labor but not the overhead of staying in business. Above it, you are either extremely efficient or you are not quoting enough to cover the real hours.

The number that matters more than the industry benchmark is your job margin. The flat rate jobs you quote with a proper hours estimate land at 12 percent, the ones you quote on the fly come in at 4. That difference is not the crew's effort. It is which pricing you started from. Your books have to be able to show you that gap.
