Electrical Estimating Software That Does the Takeoff for You

SparkQuote is electrical estimating software built for contractors who bid their own work: 1 to 50 people, residential, light commercial and tenant improvement. It replaces hours of clicking symbols and building spreadsheets with a workflow that starts from the PDF plan set and ends with a proposal.

How it works

1. Upload the plan set. Drag in the PDF drawings. SparkQuote reads the sheet index, finds the electrical sheets and detects the scale.
2. AI counts the devices. Receptacles, switches, light fixtures by type tag, panels, disconnects, data outlets. It reads the legend on your drawings so it counts your symbols, not a generic set.
3. You review. Every count is highlighted on the plan. Click to add, remove or re-assign anything the AI got wrong. You approve the takeoff; the AI never submits anything on its own.
4. Labor and pricing apply automatically. Each item carries your labor units and your prices (from your price list or a supplier quote). Adjust conditions by area: ceiling height, remodel, occupied space.
5. Send the proposal. Overhead and margin are applied, and a branded proposal is generated with your standard inclusions, exclusions and terms.

For how the detection works and where it struggles, see AI electrical estimating explained. For the takeoff tools on their own, see electrical takeoff software.

What's included

Takeoff

• AI symbol detection from the drawing legend
• Counts by area, floor or system
• Linear measurement for conduit and cable runs, with drop and waste allowances
• Plan revision comparison: see what changed between addenda

Estimating

• Your labor units by item and difficulty; start from a built-in library and tune it
• Assemblies (for example, "duplex receptacle, 20 A, 3/4" EMT home run")
• Material price lists, CSV import, and supplier quote import
• Burdened labor rate, overhead and margin, with a live margin check

Proposals and handoff

• Branded proposals with inclusions, exclusions, clarifications, alternates and unit prices
• Excel export of the full estimate
• Material list for the supply house, and a labor-hour budget for the foreman

Bidding and learning from your jobs

• A bid log with win rate by customer and job type; see electrical bidding software
• Enter actual hours after the job; SparkQuote shows estimate vs. actual by cost code and suggests updated labor units (Team plan)

How assemblies and conditions work

An assembly is everything that goes into one counted symbol. When the AI counts a 20 A duplex receptacle in an office, the assembly behind it might carry the 4" square box, the single-device mud ring, the receptacle, the plate, a share of 12 AWG branch wiring and fittings, and the labor to install each piece. You count one symbol; the estimate gets every part and every labor unit.

You build assemblies once and reuse them: "GFCI receptacle, weatherproof, exterior wall", "2×4 LED troffer with whip", "occupancy sensor, ceiling mount". The starter library covers common residential and commercial items so you're not starting from zero.

Conditions change the labor, not the count. Split the job into areas and set a condition for each: new construction, remodel, occupied space, ceiling height, access. Example: an open-ceiling warehouse area carries 40 labor hours of device and fixture work at normal conditions. With an example height factor of 15%, that area prices at 46 hours, while the office area on the same job stays at normal. Your factors are yours to set; the NECA labor units guide explains how estimators choose them.

When the addendum lands

Revised sheets usually arrive late, and re-counting a whole floor to find six moved receptacles is where mistakes creep in. Upload the new set and SparkQuote overlays it on the old one: added, removed and moved symbols are highlighted, and only those lines are re-priced. The proposal lists the addenda you acknowledged, so the GC sees exactly which documents your number covers.

Getting set up

The setup order that works best:

1. Set your burdened labor rate, overhead recovery and target margin. The bid calculator shows the math if you haven't worked it out yet.
2. Import your price list by CSV or Excel, or start with the items you buy most and add supplier quotes per job.
3. Load your labor units for the 20 to 30 items that make up most of your jobs. Keep the starter units for everything else and tune them over time.
4. Save your proposal language: inclusions, exclusions, clarifications, validity period and escalation clause.
5. Run a job you've already bid and compare the counts and totals with your original number.

Who it's for

Who it's not for

• Heavy industrial and utility work with deep existing estimating databases and dedicated estimating departments. Established desktop systems may serve you better.
• Contractors who want a full field-service platform (dispatch, GPS, payments) in one product. SparkQuote is the estimating layer and works next to those tools.
• Shops that never price from drawings. If every job is a flat-rate service call, a price book in your field-service software may be enough.

Why contractors switch

Most electrical estimating software was designed for large commercial shops with a full-time estimator trained on a desktop program. Smaller contractors usually end up in one of three places:

If you already run a deep Accubid, McCormick or ConEst database with trained estimators, those tools may still be the right choice for large commercial and industrial work. See our honest comparisons with Accubid, McCormick, PlanSwift, STACK and Procore Estimating, formerly Esticom.

How accurate is the AI takeoff?

AI symbol detection is fast, but not perfect. Drawing quality, custom symbols and cluttered sheets all affect it. That's why every count is shown on the plan for your review before it becomes part of the price.

Is it worth it? Work out your own number

Use your own inputs, measured on a job you've already bid:

Monthly value = hours saved per bid × bids per month × burdened estimator rate

Example inputs only (replace with yours):

Those 24 hours can also be spent bidding: at an example 4 hours per bid, that's time for 6 more bids a month. Compare either figure with the plan price on the pricing page.

Pricing

Plans start at $99 per month, with a free trial on your own plans and no sales call required. See pricing.

Security and your data

• Your plans, prices and labor units belong to you; export them any time.
• Files are encrypted in transit and at rest.
• Your data is not used to train models for other customers.
• User roles control who can see pricing and margin.

Frequently asked questions

What is the best electrical estimating software for small contractors?

The best choice is the one your team will actually use on every bid. Small contractors usually do best with cloud software that has fast takeoff, editable labor units and simple proposals, and that can be tested on real plans before buying.

Can AI do an electrical takeoff?

Yes, for counting symbols like devices, fixtures and panels. The estimator still reviews the counts, checks scope on other sheets, and makes judgment calls on labor and conditions.

Does SparkQuote include labor units?

Yes. It includes a starter library you can edit, and you can import your own. See NECA labor units explained for how labor units work.

Does it work on a Mac or iPad?

Yes. SparkQuote runs in the browser, so it works on Windows, Mac and tablets.

Can I import my existing price list?

Yes, by CSV or Excel. Supplier quotes can also be imported per job.

Should I buy software or use an estimating service?

If you bid regularly in your core work, in-house software keeps your labor units and judgment in the bid. Services suit overflow and unfamiliar job types; see our estimating services comparison.
