How to Make Accurate Electrical Bids for Home Service Jobs

An accurate bid is a bid you can defend

Accuracy isn't about being cheap or being thorough. It's about the number holding up — on the job, and in conversation with the customer.

A bid that's accurate protects your margin, keeps you out of awkward conversations halfway through the work, and gives the customer a reason to trust the rest of what you say.

A bid that's wrong costs you either way. Too low and you eat the difference. Too high and you never find out why you lost.

The four things that go wrong

Material priced from an old list. The most common and the least visible. Copper moves, breakers get a manufacturer increase, your supplier adjusts your tier. Nobody sends a memo.

Hours estimated optimistically. Everyone does it. The job you're picturing is the one that goes smoothly.

Non-billable time left out. Drive time, the supply house run, the callback. If your rate assumes eight billable hours and your techs bill five, the rate is a third short before you price anything.

Hidden costs forgotten. Permits, inspection fees, disposal, tax, the parts you always seem to need and never seem to write down.

Building the bid

1. Get the scope straight

The client's actual requirement, the site conditions, access, permits, and what's specifically not included. Write the exclusions down. Most change-order arguments start with something everyone assumed and nobody wrote.

2. Price material from a maintained catalog

Material costs move month to month. Use a source where keeping the prices current is somebody's job, not a spreadsheet you meant to update.

AccuPrice maintains 1,400+ electrical items with material prices updated every month — quarterly is the industry standard, and a quarter is long enough for a supplier to raise prices twice.

For the jobs you do constantly, price from assemblies rather than item by item. There are 1,400+ prebuilt ones covering panels, conduit runs, spa and mini-split circuits and device upgrades, and because each is built from catalog items, it reprices itself when material costs move.

3. Break labor down honestly

Hours per task, including setup and cleanup. Use what similar jobs actually took, not what they should have. Apply your burdened rate — wages plus payroll tax, workers' comp and benefits, not just the wage. Add after-hours or weekend premiums where they apply.

4. Carry overhead and profit deliberately

Insurance, vehicles, tools, the office, software. Carried as a rate loading or a percentage, but carried. Then set profit as a decision rather than whatever's left at the end.

5. Present it itemised

Material and labor as separate lines. It makes the number defensible, and it makes a change in scope easy to price instead of awkward to raise.

Keeping it accurate without it becoming work

The reason bids drift isn't carelessness. It's that maintaining a price book by hand loses to a busy week, every week.

What removes the work: material prices that update monthly on their own, assemblies that reprice when the items inside them move, and one markup change that recalculates every dependent line. The book syncs into QuickBooks Online and Jobber directly and exports by CSV into ServiceTitan, Housecall Pro, Workiz, ServiceM8, FieldEdge, Service Fusion or any CRM that takes an import — so your techs keep bidding where they already bid.

Frequently asked questions

How do I stop underbidding?

Price material from a catalog that's updated, and compare your estimated hours to actual hours for three months. Those two changes catch most of it.

Should home service bids be itemised?

Material and labor as separate lines is usually right. Enough detail to defend the price, not so much that the quote becomes unreadable.

How often do material prices need updating?

Monthly. Quarterly is the standard in this industry and it's too slow.

What's the fastest way to bid repeat jobs?

Flat rate tasks built from your own material and labor. One price per task, every tech quoting the same number, and it stays current because it's built on assemblies rather than typed in.

Bid from prices that are current.
