How to bid electrical jobs and win the right ones

What electrical bidding looks like right now

The Billd survey also found that subcontractors who include the cost of working capital in their bids won more often: 32% of them won more than half their bids, against 19% of those who rarely or never account for it.¹ Pricing the real cost of carrying a job is part of bidding, not an afterthought.

Where to find electrical jobs to bid

Most commercial electrical work reaches contractors in one of three ways: invitations to bid from general contractors you already work with, public agencies that advertise their projects, and paid lead services and bid boards that collect projects from both. The best source of profitable work is usually the first one, but new relationships start with the other two. These are the main electrical bidding websites, with what each says about itself.

As described on each site, checked November 3, 2026. Plans and prices change; check with the provider.

For electrical jobs to bid near you, set every service to your market and service radius, and save searches by trade and building type so new projects arrive by email. Local builders exchanges and the plan rooms of the general contractors you want to work for are worth checking too; many private projects never appear on national services. Once invitations come in from several places, a shared bid board keeps due dates from slipping; the guide to construction bidding and bid management software compares the tools that do it.

Decide go or no-go before you estimate

Estimating hours are the scarcest thing in most electrical contracting firms, and they are not cheap: the electrical estimator salary data shows what one of those hours costs once benefits are added. Before opening the drawings, spend ten minutes on these questions. A simple way to use them: score each from 1 (bad) to 3 (good) and set a minimum total for the jobs you will bid.

How to bid commercial electrical jobs

A commercial electrical bid follows the estimate. The electrical estimating guide covers the nine steps in detail: bid documents, scope, takeoff, material, labor units, labor rate, job costs, overhead and profit, review. Bidding adds the parts around the estimate:

• Log the invitation with the due date, bid time, delivery method, RFI deadline and job walk date.
• Request supplier quotes early, with the fixture schedule, panel schedules and one-line attached, so quotes arrive before bid day.
• Send questions before the RFI deadline. Unclear scope becomes a written exclusion if it is not answered.
• Attend the job walk on renovations and occupied buildings; existing conditions drive labor.
• Do the takeoff early. Counts and measurements do not depend on quotes, and they are what takes longest. The guide to AI takeoff software explains which parts of that counting tools can now do for you.
• Watch for addenda until the last day and price each one.

Electrical bid example: a bid summary

Here is what a finished bid summary looks like for a tenant fit-out. All numbers are made up to show the structure and the arithmetic. They are not market prices, published costs or a benchmark for your market.

Before sending, divide the bid by the floor area and compare it with your own completed jobs of the same type. If the number is far from your history, find out why before the bid goes out. The electrical cost per square foot guide shows how to build that history and includes RSMeans medians by building type. To try the same summary with your own lines and margin, the electrical estimate calculator does the markup and margin math in the browser.

The proposal: what an electrical bid should say

The number is only half of the bid. The proposal letter says what the number buys, and it is what you will point to after award. A complete electrical proposal includes:

• Project name, bid date, and the drawings, specifications and addenda the price is based on, listed by number and date
• Base bid price, and each alternate and unit price exactly as the bid form asks
• Inclusions by system: power, lighting, gear, fire alarm, low voltage, site work
• Exclusions and by-others items, in plain words
• Qualifications: assumptions on schedule, working hours, utility charges, owner-furnished equipment
• How long the price is valid, and how long-lead gear pricing is handled
• Contact for questions

The electrical bid template is a free proposal you can fill in and send. When fire alarm, data or security are in your number, list each one by system; the low voltage takeoff guide covers how those scopes are counted and priced.

How to bid electrical jobs by square foot

Bidding by the square foot means multiplying the floor area by a dollars per square foot rate from past jobs. It is fast, and it is fine for budget numbers, design-build pricing before drawings exist, and a check on a detailed bid. It is risky as the basis of a hard bid: Gordian puts square foot estimates at roughly 20% of final cost, against about 10% for a unit price estimate built from quantities.⁹ On a competitive electrical bid, that gap is larger than the margin. If you must price by the square foot, use your own history for the same building type, state the basis in the proposal, and list what the price assumes.

How to bid residential electrical work

Residential and commercial electrical bidding share the arithmetic and little else. If you are learning how to bid residential electrical jobs, or moving from residential into commercial, these are the differences that matter most.

For residential work, a per-opening price list kept up to date with your real costs is the backbone, adjusted for access, panel upgrades and finishes. For builders, price each plan once and update it when material moves. On a panel upgrade, run a load calculation under NEC Article 220 before you quote, so the service size in your price is the one the inspector will accept.

Follow up and track your hit rate

The bid is not over at the deadline. Call the general contractor a few days after bid day, ask where you landed and what the difference was. On many public bids the results are read at the bid opening or posted afterward; some lead services also report awarded contractors and low bidders on public and private projects.⁵ Keep a log of every bid:

• Customer, building type, bid value and estimating hours spent
• Result: won, lost, no award, or never heard back
• When lost: to whom, by how much, and why (price, scope, relationship)

Hit rate = bids won / bids submitted (track it by count and by dollar value)

After a year the log tells you which customers and building types you actually win, which ones you only feed numbers to, and what each win costs in estimating hours. That is the data for your next go or no-go decision. For tools that manage the pipeline, see electrical bidding software.

Where AmpCount fits

More bids with the same team means less time per takeoff. AmpCount counts the devices and fixtures on a vector PDF set from its legend, on every sheet, keeps uncertain marks out of the count until you confirm them, and checks fixtures against the schedule, so the counting part of a bid takes minutes instead of a day. Pricing, labor and the proposal stay in your own tools, whether that is Trimble Accubid, another estimating program or a spreadsheet.
