Job costing software for electricians: keeping rough-in and finish from eating the bid
An electrical bid is only as good as the copper price on the day you priced it. Wire and panel costs can move meaningfully between the bid and the pull, and if nobody is watching the job's actual material spend against what was estimated, the first sign of trouble is a supply house invoice that doesn't match the number in your head.
Add in rough-in and finish being two very different labor phases, permit and inspection delays that stretch a job's calendar without changing its scope, and service calls mixed in with project work on the same crew's day, and it's easy to see why so many electrical contractors know their company made money this year without being able to say which jobs did it.
Where electrical job costs actually go sideways
- Material price volatility — copper and wire pricing can shift between the day you bid a job and the day you buy for it, and a fixed-price contract eats that difference.
- Rough-in vs. finish labor splits — the two phases have different crew sizes and different pace, and if hours aren't tagged to the phase, a slow finish looks like a slow job instead of pointing at the actual cause.
- Permit and inspection delays — a failed rough-in inspection or a slow permit office doesn't cost material, but it burns calendar days and sometimes a mobilization trip that never gets billed unless someone tracks it.
- Service call vs. project job costing — a truck running both is common, but a two-hour service call and a six-week new-construction job need to be costed completely differently, or the service work quietly subsidizes the project work.
None of these show up on a monthly P&L. They show up on a specific job's numbers, days or weeks after the fact, by which point the panel is already set and the crew has moved to the next address.
What to check before buying
| Question | Why it matters for electrical work |
|---|---|
| Does material cost post to the job the moment it's bought? | A supply house receipt sitting in a truck for two weeks either gets coded to the wrong job or never gets coded at all — and copper isn't cheap enough to lose track of. |
| Can hours be tracked by job site, not just by day? | A crew that does rough-in on one job in the morning and a service call on another in the afternoon needs both legs costed correctly, not lumped into one day's labor. |
| Can you see a job's margin while it's still open? | Rough-in going over on labor is fixable before finish starts. The same overage discovered at close-out is just a number on a report. |
| Does it work without signal? | Panels get set in basements and mechanical rooms with no cell signal. Software that needs a connection to log a receipt or a clock-in gets skipped, and skipped entries are the ones that cost you. |
Rough-in, finish, and service calls as separate jobs
The contractors who get the clearest read on their numbers treat rough-in and finish as trackable phases of the same job rather than one undifferentiated labor bucket, and they keep service work and project work on separate job records even when it's the same crew and the same truck. It sounds like more setup, but it's the difference between "this job ran over" and "rough-in ran two days long because of the inspection delay, and finish came in on budget" — one of those tells you what to fix next time.
A simple test: pull last month's three biggest jobs and see if you can say, right now, what rough-in labor cost versus finish labor cost on each one. If the answer is "I'd have to go back through timesheets," that's the gap job costing software is meant to close.
The callback nobody costs
Electrical work generates a particular kind of unbilled labour: the return visit. A device that does not work at handover, a breaker that trips under load once the tenant moves in, a fixture the customer swapped after finish. Each one is an hour or two and a drive, and almost none of it gets logged against the job that caused it because the job is closed.
Over a year that adds up to a real number, and because it is invisible it never influences pricing. The contractors who get on top of it keep the job record open for a defined warranty window and let return visits post against it. The point is not to bill the customer, it is to know that a certain kind of job reliably costs you three extra visits so you can price the next one accordingly.
What to do this week
Take your last three completed jobs and split the labour into rough in and finish. If you cannot do it without opening individual timesheets, that is the gap. Then check whether any return visits happened after handover and whether they appear anywhere on the job.
Most electrical contractors find the same two things: finish ran longer than they thought, and the callbacks were free work nobody counted. Neither is fixable retrospectively, and both are entirely fixable on the next job once you can see them.
Where SiteLedger fits
SiteLedger gives electrical contractors geofenced time tracking so hours post to the right job site automatically, AI receipt scanning that reads the vendor and total off a supply house receipt in about 4 seconds — including from a phone with no signal, syncing once it's back — and live per-job margin so a rough-in that's running long shows up while there's still time to adjust the crew before finish starts.
It's $8/month for up to 10 workers on the Starter plan, or $15/month for unlimited workers with AI budget alerts and calendar scheduling on Professional. Both start with a 1-week free trial and no credit card. Timesheets export payroll-ready, and it syncs directly with QuickBooks Online; Xero and other payroll providers work through a CSV export rather than a live sync.
Common questions
- How do I track material cost when copper prices change mid-job?
- The fix isn't predicting the price — it's seeing the actual cost as it's incurred instead of at the final invoice. Photographing supply house receipts as you buy, with the cost posting to the specific job immediately, means you see a material overage while the job is still open, not three weeks after you've already closed it out.
- Should rough-in and finish be tracked as one job or two?
- One job, two phases. Splitting them entirely loses the whole-job margin picture; lumping them together loses the ability to tell which phase actually ran over. Tagging labor hours to the phase within the same job gets you both.
- What about time lost to permit delays or a failed inspection?
- That time doesn't disappear from the crew's day even though it's not billable progress. If a mobilization trip or a stalled crew day isn't logged against the job, it quietly erodes margin without ever showing up as a line item you can point to.
- Can the same software handle service calls and new-construction jobs?
- Yes, as long as each is tracked as its own job record with its own budget and its own costs — a two-hour service call and a six-week rough-in-to-finish build shouldn't share a bucket, even when the same electrician works both in one day.
