How to Create Accurate Electrical Estimates

Accuracy is mostly one number

An estimate has four parts — material, labor, overhead, profit. Three of them you set once and revisit occasionally. One of them moves on its own.

Material is the one that moves. Copper shifts, breakers get a manufacturer increase, your supplier adjusts your tier. If the prices in your estimate are from last spring, the estimate is wrong before anyone reads it — and it's wrong in the direction that costs you money, because prices rise more often than they fall.

Everything below is about getting that number right and keeping it right.

Step 1: Work from a catalog that gets maintained

Not a spreadsheet someone built once. Not a supplier PDF from last year. A maintained catalog where the prices are somebody's job.

AccuPrice maintains 1,400+ electrical items — wire, conduit and fittings, boxes, devices, breakers, panels, and the hardware between them — with material costs updated every month and prices reviewed by working electricians.

The list being comprehensive matters less than it being current. A thousand items priced last year is worse than five hundred priced last month.

Step 2: Set your markup and tax once

Material cost isn't your price. Your price is material plus markup, plus labor at your rate, plus tax where it applies.

Set markup by category if your categories behave differently — wire and gear often warrant different treatment. Set your sales tax rules. Then leave them alone until something changes, and when it does, change them in one place so every line recalculates.

The mistake is applying markup by hand, job by job. It's slow and it drifts.

Step 3: Use assemblies for the work you repeat

Most service work is the same twenty jobs over and over. Pricing each one from individual items every time is wasted effort and an invitation to leave something off.

An assembly is the material for a whole job bundled together — a panel change, a conduit run, a spa circuit, a receptacle upgrade — with labor included. AccuPrice ships 1,400+ prebuilt assemblies plus 75 prebuilt labor services, and you can build your own.

The part that matters: because an assembly is built from catalog items, it reprices itself when those items move. You build it once. It stays current on its own.

Step 4: Get it into the software you already use

Estimates should be written where you already write them.

Direct sync into QuickBooks Online and Jobber — items, descriptions and prices land in your catalog and stay updated
CSV export and bulk import into ServiceTitan, Housecall Pro, Workiz, ServiceM8, Service Fusion or any CRM that takes an import
FieldEdge through QuickBooks

No retyping, no second system for your techs to learn.

Step 5: Update monthly, not quarterly

Quarterly is the standard across this industry, and it's the wrong cadence.

A quarter is long enough for a supplier to raise prices twice. By week ten you're quoting numbers that have been wrong for two months, and you have no way of knowing by how much.

Monthly updates cut that exposure to a few weeks. On a $400 material package, the difference between being three weeks behind and three months behind is the difference between a rounding error and real money.

Then show the customer what they're paying for

Break material and labor onto separate lines. It does two things: it makes the number defensible when someone questions it, and it makes a change in scope easy to price instead of awkward to raise.

A customer who can see where the money goes argues about the price far less often than one looking at a single figure.

Frequently asked questions

How often should I update material prices in my estimates?

Monthly. Quarterly is the industry standard and it's long enough for a supplier to raise prices twice inside one cycle.

What's the most common cause of an inaccurate estimate?

Material priced from a list that's months old. Labor estimates get scrutinised; material prices get trusted.

Do I need estimating software?

Not necessarily. You need current material prices inside whatever you already use. AccuPrice syncs into QuickBooks Online and Jobber directly and exports by CSV to other CRMs.

Should I show customers a full breakdown?

Material and labor as separate lines is usually the right level. Enough to defend the price, not so much that the quote becomes a document nobody reads.
