Here's the problem with most electrical contractor bookkeeping: it treats an electrical business like one company, when really you're running two. You've got service work — the calls, the repairs, the panel swaps, the troubleshooting that keeps the phone ringing — and you've got project work — the new construction, the commercial wire jobs, the tenant improvements that put six figures on a single contract. Those two sides of your business make money in completely different ways. And if your books can't tell them apart, you genuinely don't know which one is carrying the company and which one is quietly dragging it down.
This is the 2026 owner's guide to electrician bookkeeping — written for electrical contractor owners, not accountants. We'll cover why service and project work have to be costed separately, how to actually track material markup so you stop giving it away, the five numbers every electrical contractor should be able to pull from their books, and what good electrical contractor accounting looks like for a business that runs both sides. Every example is electrician-specific, because generic construction bookkeeping advice misses what makes an electrical business different.
If you're an electrical contractor who can't quickly answer 'is my service department more profitable than my projects?' — or you suspect you're losing markup on material but can't prove it — this guide is for you. As a construction bookkeeper team that sets up bookkeeping for electricians, our goal here is to show you what your books should be telling you.
You're Running Two Businesses, Not One
The single biggest mistake in electrical business bookkeeping is running service and project work through one undifferentiated set of books. They look like the same business — same trucks, same electricians, same supply house — but financially they could not be more different. Here's how the two sides actually compare:
ONE ELECTRICAL COMPANY, TWO DIFFERENT BUSINESSES
Service work and project work cost out completely differently — and your books have to tell them apart
SERVICE WORK | PROJECT WORK |
Service calls, repairs, troubleshooting, panel swaps, small installs | New construction, commercial wire jobs, tenant improvements, large installs |
Costed per: TICKET Hundreds of small jobs, fast turnover, flat-rate or T&M pricing | Costed per: JOB / PHASE Few large jobs, months long, fixed-price or progress-billed |
Material: Pulled from truck stock | Material: Ordered per job, staged, often large |
Margin: Higher % but small $ per ticket | Margin: Lower % but large $ per job |
Cash: Paid fast, often on completion | Cash: Slow, retention, progress billing, 30-90 day pay |

If your books lump these together, you cannot answer the most important question in your business: which side is actually making money? The margins, cash timing, and material flow are completely different — so the bookkeeping has to be too.
Look at the differences. Service work is high-volume, fast-cash, higher-margin-per-dollar but small dollars per ticket. Project work is low-volume, slow-cash, lower-margin-percentage but huge dollars per job. When you blend them into one P&L, the averages lie to you. A great service month can hide a project that's bleeding. A profitable project can mask a service department that's barely breaking even. Service and project job costing done separately is the only way to see the truth.
FROM THE OWNER'S CHAIR: The first question we ask a new electrical contractor client is simple: 'Is your service work or your project work more profitable?' Most owners have a gut answer. When we separate the books and actually show them, the gut answer is wrong about half the time. That's the whole point of trade-specific bookkeeping — it replaces your gut with real numbers. |
Costing Service Work: Hundreds of Small Jobs
Service work breaks the standard construction job costing model because of volume. You're not running five jobs a month — you're running a hundred service tickets. You can't build a full WIP schedule for a two-hour panel repair. So job costing for electricians on the service side works differently: you cost at the ticket level, and you watch the margin in aggregate.
For service work, your books need to track, per ticket:
Labor — the tech's time on the call, at their true loaded cost (wage + burden), not just their hourly wage
Material — what got pulled off the truck and used, at cost, so you know what to mark up
Markup captured — the difference between what you paid for the material and what you billed the customer for it
Ticket margin — what was left after labor and material, per ticket and in aggregate by month
Service and project job costing are two different disciplines, and the service side is the one most electrical contractors get wrong — because the volume makes it tempting to skip costing altogether. Don't. The goal isn't a giant report per ticket — it's a clean rollup. At month-end you should see total service revenue, total service labor cost, total service material cost, and your blended service margin. If your service margin is running below 50%, something is leaking — usually unbilled material markup or tech time that isn't getting captured against tickets. Strong electrical contractor job costing on the service side catches that leak.
⚠ RED FLAG: The most common service-side leak: material markup that never makes it onto the invoice. A tech pulls $80 of wire and devices off the truck, does the job, and bills for labor plus a round number that doesn't actually capture the markup on what was used. Multiply that by a hundred tickets a month and you're giving away thousands in margin you never see. Your books should track material used per ticket so the markup gets billed every time. |
Costing Project Work: A Few Big Jobs
Project work is where electrical contractor job costing looks more like traditional construction. Fewer jobs, much bigger dollars, months-long timelines, and real exposure if a job runs over. On the project side, you cost by job and by phase — rough-in, finish, service, fixtures — so you can see where a job is winning or losing while you can still do something about it.
For project work, your books need to track, per job:
Labor by phase — rough-in labor vs finish labor, against the estimate for each, so you catch a phase running over early
Material by job — wire, panels, gear, fixtures ordered and staged for that specific job, not pulled from general stock
Subcontractor or rental costs — trenching, lifts, anything outsourced or rented for the job
Billing vs cost — whether you're over-billed or under-billed on the job right now, which drives your cash position
This is where proper cost codes matter. Each electrical phase should map to its own cost code, so your project job costing reports show exactly where the money went — and your estimate-vs-actual tells you how to bid the next job better. (For the cost code structure that makes this work, see our cost codes guide → [link to: /post/construction-cost-codes-2026-guide], and for reading the resulting reports, our job costing reports guide → [link to: /post/construction-job-costing-reports-2026-guide].)
OWNER'S TAKEAWAY: On project work, the number that quietly kills electrical contractors is underbilling — you've wired most of the building but you've only billed for half of it. You're funding the rest out of pocket. Your books should flag underbilled jobs every month so you get the invoices out before the cash gap hits. |
Can't Tell If Service or Projects Make You More Money?
Most electrical contractors run service and project work out of one set of books that can't separate them — so the owner never knows which side actually drives profit. CCA sets up electrical contractor bookkeeping that splits the two cleanly, tracks material and labor by job, and shows you real margin on both. In a 30-minute call, we'll review how your books handle the service-plus-project split today.

Material Markup: The Margin Electricians Give Away
Electrical work is material-heavy — wire, conduit, panels, breakers, devices, fixtures, gear. On many jobs, material is 40-50% of the total cost. That makes material markup one of the biggest levers in your business, and one of the most commonly mishandled in electrical business bookkeeping. If you're not capturing markup cleanly, you're leaving real money on the table on every job.
Good electrical contractor accounting tracks material two ways: what you paid for it (your cost, from the supply house invoice) and what you billed for it (your price to the customer). The gap is your markup, and it should be visible — not buried. When material cost and material billing are tracked separately in your books, you can see your actual markup percentage by job and by month. When they're lumped together, the markup disappears and you have no idea whether you're charging enough.
This matters even more with material prices moving the way they have. When copper and gear prices jump, a markup percentage you set two years ago may not cover your real cost anymore. Books that track material cost vs billing let you catch that and adjust — protecting your electrical contractor profit margin instead of watching it erode quietly as prices climb.
The 5 Numbers Every Electrical Contractor Should Track
If your electrical contractor bookkeeping can't produce these five numbers, it isn't built for an electrical business. These are the metrics that tell an electrical contractor owner whether the business is actually healthy:
THE 5 NUMBERS EVERY ELECTRICAL CONTRACTOR SHOULD TRACK
If your books can't produce these five, they're not built for an electrical contractor
1 | Service margin % | Are your service calls actually profitable after material and tech time? Target 50-60% gross on service. |
2 | Project margin % by job | Which project jobs hit margin and which bled? Target 20-30% gross on project work. |
3 | Material markup capture | Are you actually billing the markup on wire, panels, and fixtures — or losing it in the noise? |
4 | Labor cost per tech / crew | Which electricians and crews are profitable, and which jobs run their hours over? |
5 | Unbilled / underbilled work | Service tickets sitting unbilled and project work done but not invoiced — pure cash drain. |
None of these five require an accounting degree to read. They require books that are set up for an electrical contractor — service and project separated, material markup tracked, labor costed by job and crew. With those five numbers in front of you each month, you run the business off facts. Without them, you're running it off the bank balance and a gut feeling, which is how profitable-looking electrical companies end up cash-stressed and margin-thin. Protecting your electrical contractor profit margin starts with being able to see it — by service, by project, and by job.
An electrical contractor who knows their service margin, project margin, and material markup by the numbers will out-earn a better electrician who's guessing — every time. The work wins jobs. The books decide whether the jobs make money. |
Software: QuickBooks for Electricians
Most electrical contractors land on QuickBooks for electricians as their accounting system — and it works well when it's set up for the trade. The key is configuration: a construction-specific chart of accounts, cost codes for your electrical phases, and items set up to separate service from project and to track material cost vs billing. Out of the box, QuickBooks doesn't know you're an electrical contractor. Set up correctly, it handles electrician bookkeeping cleanly.
Many electrical contractors also run a field service platform — for dispatching service calls, scheduling, and invoicing from the truck. That electrician accounting software stack works when the field platform and your books are connected and mapped correctly, so service tickets flow into your accounting without double entry. When they're not connected properly, your service revenue and material usage don't reconcile — and your service margin number becomes unreliable. Getting the electrician accounting software setup right is part of what makes the whole system produce numbers you can trust.

In 2026, the electrical contractors who win aren't always the best electricians — they're the ones who know their numbers. Electrical contractor bookkeeping done right separates your service business from your project business, tracks the material markup you're currently giving away, costs labor by job and crew, and hands you the five numbers that tell you exactly where your money is made and lost.
The owners who run electrical companies well share one habit: they treat service and project as two businesses, track them separately, and make decisions off real margin numbers. The owners who struggle blend everything into one P&L, never quite know which side is profitable, and slowly lose markup they can't see. The difference isn't the electrical work — it's the electrical business bookkeeping underneath it.
Construction Cost Accounting builds electrical contractor bookkeeping that shows you the truth about your business — service versus project, real material markup, and profit by crew.
