Obra for Electrical contractors

Job costing for electrical contractors: wire, panels, fixtures and the margin on each job

Expense tracking for electrical contractors on project work: material runs split by job, panel upgrades as change orders, and a per-job margin that holds up.

Electrical project work has a specific margin problem: the material is bought in runs, on one supply-house ticket for three jobs, and the labor is the largest line. A rewire can be bid at a healthy margin and finish at a thin one without a single obvious mistake, because the wire was split wrong between jobs and the inspector's panel never became a change order.

Obra keeps each job's money separate from the ticket up. A supply-house receipt is read into a draft and split across the jobs it served, each with its cost code. The panel the inspector required is a change order on the contract the day it's quoted. Labor is confirmed to the job at its burdened rate. The page shows the job's expected margin while the trim-out is still ahead.

Material runs, honestly split

The truck stops at the supply house once for three jobs. One receipt, $1,840, three projects. In most systems that receipt goes to whichever job the bookkeeper guesses, or to overhead, and two jobs look cheaper than they were. In Obra the draft is split when it's confirmed, from the photo, and every job carries its share with the ticket attached.

The service upgrade that pays for itself, or doesn't

An inspector requires a 200A service where the bid assumed 100A. The right afternoon looks like this: quote the upgrade, write the change order, get it signed, add the panel to the forecast's remaining to spend, install. The change order guide is the short form, and the pricing calculator makes sure it carries markup. The wrong afternoon is installing it to pass and hoping the client remembers the conversation.

Labor at its real cost

Electrical crews are expensive, and the wage is not the cost. Taxes, insurance, downtime and training push a $34 wage toward $50 an hour; the labor burden calculator finds your number. Obra records labor on the job at that rate, so the margin on the page is the margin you'd see at tax time, not the one that ignores the truck.

What Obra doesn't do for an electrician

Service dispatch, flat-rate price books, invoicing at the door. Those are field-service tools' jobs. Obra is for the contract work with a budget and a finish date, in English and Spanish, from the receipts the crew already sends.

The change orders that eat the margin

The panel the inspector required
A subpanel or a service upgrade the drawings didn't call for. Quoted and signed before the wire goes in, it's a change order; installed to pass inspection, it's yours.
Fixtures the client changed after rough-in
Recessed to pendants, one switch to three-way, a new circuit for the sauna. Each is an hour plus material, and each is only billable if it was written down before the drywall went up.
Copper that moved between bid and buy
A bid written in March and bought in June can be several hundred dollars different in wire alone. Recording the receipt against the bid line shows the gap while the job can still absorb it.

Questions people ask

We buy material for several jobs on one supply-house ticket. How does that work?
Split the draft when you confirm it: one receipt, several entries, each on its job with its cost code. The supply-house photo is attached to all of them.
Does Obra do flat-rate pricing or service tickets?
No. Obra is for project work with a contract and a budget: rewires, service upgrades, tenant fit-outs, new construction. A service-call business is better served by a field-service tool.
Can the apprentice send receipts?
Yes, as a submitter, from their own phone or WhatsApp, without seeing the job's finances. A reviewer confirms each draft.
How does labor get onto the job?
As an expense claim or a labor entry confirmed to the job, at the burdened rate. The labor burden calculator finds that rate; Obra does not track time clocks.
