Electrical Estimating

Best Electrical Estimating Software for Contractors in 2026

Quick answer

The best electrical estimating software depends on the kind of electrical work you bid. For commercial electrical subcontractors who take off devices, conduit, and wire from plans, apply NECA labor hours, and submit a Schedule of Values to a GC, ScopeTakeoff is the strongest affordable fit. For a deep commercial/industrial specialist with a 55,000-item catalog and patented home-run logic, McCormick is a long-standing choice, and Trimble Accubid is the other established standard with AI symbol detection. ConEst IntelliBid is strong for low-voltage, datacom, and solar. Excel still works for simple, low-volume bids.

Electrical estimating software is not one category. Some tools are deep commercial/industrial estimating systems built around 40,000-to-1-million-item catalogs and NECA labor units. Some are cloud platforms with AI symbol detection and supply-house pricing. Some are low-voltage and datacom specialists. And some are takeoff-and-bid tools for subcontractors who need NECA-based labor hours and a clean Schedule of Values for the GC.

That is why “best electrical estimating software” has different answers for different contractors. This comparison is organized around who each tool is for, so you can match the software to your work — commercial subcontract bidding, deep industrial estimating, or low-voltage and datacom.

Quick guide to who each tool is for: ScopeTakeoff → commercial electrical subs taking off devices, conduit, and wire from plans with NECA labor hours and SOV output. McCormick → deep commercial/industrial electrical estimating with a massive catalog and patented home-run automation. Trimble Accubid → the other long-tenured standard, with AI symbol detection and cloud multi-user. ConEst IntelliBid → low-voltage, datacom, and solar specialist with a large customizable database. Excel → simple, low-volume manual estimates.

  • Best free option: Excel

1. ScopeTakeoff — Best for Commercial Electrical Subcontractors

Top Pick — Commercial Electrical Subs
1 ScopeTakeoff
$100/person/month

Who it’s for: commercial electrical subcontractors who take off devices, lighting, conduit, and wire from plans on commercial, multi-family, healthcare, and institutional projects, apply NECA labor hours, and submit a Schedule of Values to a general contractor. If you estimate heavy industrial work with a 100,000-plus-item manufacturer catalog, the specialists below will fit you better — and that is the honest answer.

For commercial electrical, ScopeTakeoff supports PDF plan takeoff so you can count receptacles, switches, fixtures, and gear, measure conduit runs by linear foot and size, and trace each system directly from the electrical drawings, then push those quantities into electrical assemblies. Instead of measuring in one place and pricing in another, the takeoff feeds the estimate.

Electrical estimators work in labor hours, not just dollars: ScopeTakeoff stores NECA-style labor units as hours per device, per 100 ft of conduit, and per 1,000 ft of wire, with Normal, Difficult, and Very Difficult columns and a labor-factoring stack you control. Conduit runs automatically calculate the conductors inside them — wire footage derived from the run length, conductor count, and a makeup allowance — so you are not tallying wire by hand. The Division 26 assembly library covers branch wiring, feeders, gear, and lighting, with material and labor on separate rails and a burdened composite labor rate. ScopeTakeoff also includes SOV exports for GC submission, unlimited projects, team estimating tools, multi-entity profiles, and proposal output. At $100 per person per month with a 14-day free trial, it runs in any browser, needs no Windows install, and is priced for subcontractors rather than enterprise electrical shops.

Pros
  • Built for commercial electrical takeoff and bidding
  • Web-based — Mac, PC, tablet, mobile; no install
  • NECA-style labor stored as hours (Normal / Difficult / Very Difficult)
  • Conduit-to-wire auto-calc with makeup allowance
  • Division 26 assemblies for devices, conduit, gear, lighting
  • Separate material and labor rails with burdened composite rate
  • SOV output for GC submission
  • $100/person/month with no annual contract
Cons
  • No 100k-item manufacturer catalog with licensed NECA units
  • Not built for deep industrial estimating
  • No live supply-house price syncing
  • Newer product with less name recognition
Bottom line: ScopeTakeoff is the best fit for commercial electrical subcontractors who bid from plans and need device and conduit takeoff, NECA-style labor hours, conduit-to-wire calculation, Division 26 assemblies, SOV output, and proposals in one web-based system. Deep industrial shops should look at McCormick or Accubid.

2. McCormick — Best Deep Commercial/Industrial Specialist

2 McCormick Systems
~$300/mo, quote tiers

Who it’s for: established commercial and industrial electrical contractors who need a deep catalog, NECA labor units, and unified takeoff plus estimating in one platform.

McCormick has been a specialist in electrical estimating since the late 1970s. It combines on-screen takeoff (through its Design Estimating Pro tool) with estimating in a single environment, so quantities flow straight from measurement into a priced bid. It ships with a large prebuilt electrical database — more than 55,000 items and 25,000 assemblies — plus auto-count, NECA Levels 1 through 3 labor units, and the patented Auto Home Run feature that speeds repetitive wiring logic. The tradeoffs are scope and price: it is a full estimating platform with tiered, quote-based pricing reported to start around $300 per month and climb with company size, geared to established shops rather than a sub who mainly needs fast takeoff plus a GC Schedule of Values.

Pros
  • Deep commercial/industrial electrical estimating
  • 55,000+ items and 25,000+ assemblies
  • NECA Levels 1–3 labor units built in
  • Patented Auto Home Run for wiring logic
  • Unified takeoff and estimating in one platform
Cons
  • Tiered, quote-based pricing geared to larger shops
  • Implementation and per-user training costs
  • Learning curve to set up catalogs and assemblies
  • Output geared to a bid summary, not a fixed GC SOV
Bottom line: McCormick is the right tool for established commercial/industrial electrical contractors who want catalog depth and NECA labor. Subs who mainly need fast plan takeoff and a clean SOV at a flat price may prefer a lighter, web-based tool.

3. Trimble Accubid — Best Established Cloud Platform

3 Trimble Accubid
$2k one-time / quote

Who it’s for: mid-to-large electrical contractors and estimating departments that want a long-tenured industry standard with deep databases and multi-user cloud collaboration.

Accubid is the other long-standing standard in commercial electrical estimating, now part of Trimble. It comes in two forms: Accubid Classic, a desktop application available as a one-time purchase (listed around $2,000), and Accubid Anywhere, the cloud-hosted subscription for multi-user deployments. Both ship with deep electrical databases — tens of thousands of items and assemblies — plus advanced labor factoring, and Anywhere adds AI symbol detection through Trimble LiveCount for graphical takeoff and lets multiple estimators work the same project from shared databases. The tradeoffs are cost and complexity: pricing is enterprise-oriented and quote-based for Anywhere, the feature depth carries a learning curve, and the bid output is geared to a summary rather than a built-in GC Schedule of Values.

Pros
  • Long-tenured industry standard for commercial electrical
  • Deep item and assembly databases
  • AI symbol detection on the cloud tier
  • Multi-user cloud collaboration (Anywhere)
  • Advanced labor factoring; Trimble suite integration
Cons
  • Enterprise-oriented, quote-based pricing for cloud
  • Learning curve to set up and maintain
  • More platform than a small sub needs
  • Bid summary rather than a built-in SOV workflow
Bottom line: Accubid is a strong choice for mid-to-large electrical contractors with dedicated estimating staff who want catalog depth and multi-user collaboration. Smaller subs focused on fast bids and SOV output may find it broader than necessary.

4. ConEst IntelliBid — Best for Low-Voltage & Datacom

4 ConEst IntelliBid
Quote-based

Who it’s for: electrical, low-voltage, datacom, and solar contractors who want a large customizable database and a platform that spans those scopes.

ConEst IntelliBid is electrical estimating software aimed at electrical, low-voltage, datacom, and solar contractors, built around one of the largest customizable item and materials databases in the category. It pairs that database with assemblies and digital takeoff so estimators can produce bids faster and more consistently, and its breadth across low-voltage and systems work is a real differentiator for contractors who live in those scopes. The tradeoffs are the usual full-platform ones: it is Windows-based with quote-based pricing and a setup investment, oriented to a complete estimating department rather than a sub who mainly needs fast takeoff and a GC Schedule of Values.

Pros
  • Strong for low-voltage, datacom, and solar
  • One of the largest customizable databases in the category
  • Assemblies plus digital takeoff
  • Consistent, repeatable estimating across systems work
Cons
  • Quote-based pricing geared to established shops
  • Windows-based platform
  • Database and assembly setup takes time
  • Output geared to bid summary, not a fixed GC SOV
Bottom line: ConEst IntelliBid is a strong platform for contractors whose work spans low-voltage, datacom, and solar alongside power. Commercial subs bidding straightforward power scopes from plans with SOV output may want a lighter, takeoff-first tool.

5. Excel — Best Free Option

5 Microsoft Excel
Free / Microsoft 365

Who it’s for: contractors doing a low volume of electrical bids who want a free, familiar starting point.

Most electrical contractors start with Excel — a device count, a conduit-and-wire tally, and a material-and-labor sheet. It works at low volume. The problems start when you are bidding several commercial jobs a week with multiple systems, where manual device counts, conduit-to-wire math, and labor-hour application become error-prone — and miscounting devices or under-figuring wire on a multi-story feeder scope costs real money.

Pros
  • Free and familiar
  • Fully customizable for any electrical scope
  • Useful for simple estimates
  • Works as a backup tool
Cons
  • No electrical item catalog or assemblies
  • No NECA labor units or labor-hour math
  • No PDF plan takeoff; conduit-to-wire is manual
  • SOV formatting is manual for every GC
  • Error-prone at higher volume
Bottom line: Excel is viable for a few electrical bids a month. At higher volume the time cost quickly exceeds the price of dedicated estimating software.

How to choose electrical estimating software

The first question is not features — it is what kind of electrical work pays your bills. Start there, then match the criteria below.

  • Commercial subcontract vs. industrial: Commercial electrical subcontracting needs plan takeoff, NECA labor hours, and SOV output for the GC; deep industrial estimating needs a huge manufacturer catalog and spec-driven takeoff. Weight the side that drives your revenue.
  • Labor stored as hours: Electrical is bid in labor hours, not just dollars. Look for NECA-style labor units per device, per 100 ft of conduit, and per 1,000 ft of wire — with difficulty columns and a factoring stack you control.
  • Conduit-to-wire calculation: Wire footage follows the conduit run, the conductor count, and a makeup allowance. The tool should derive wire from conduit automatically rather than making you tally it by hand.
  • Device and gear takeoff: You count receptacles, switches, fixtures, panels, and gear and measure conduit by size and length. The tool should handle count, linear, and diameter takeoff cleanly.
  • Material and labor on separate rails: Electrical recaps keep material and labor separate, then apply a burdened composite labor rate. Confirm the tool does this rather than blending them into one number.
  • Platform: Windows-only desktop tools tie you to one machine; web-based tools work from the office, the truck, or the field.
  • SOV output: Commercial GCs require a Schedule of Values formatted to spec — confirm the tool produces it, not just a bid summary.

Recommendation for commercial electrical subcontractors: If you bid devices, conduit, and wire from plans and submit to GCs, start with a takeoff-and-SOV estimating tool with real NECA-style labor hours rather than a 100k-item industrial catalog. ScopeTakeoff is built around Division 26 assemblies, plan takeoff, NECA labor hours, conduit-to-wire calculation, and SOV output at $100/person/month.

FAQ

What is the best electrical estimating software for contractors?+
It depends on your work. For commercial electrical subcontractors bidding from plans, ScopeTakeoff offers Division 26 assemblies, NECA-style labor hours, conduit-to-wire calculation, and SOV output at $100 per person per month. For a deep commercial/industrial specialist with a 55,000-item catalog and patented home-run logic, McCormick is a long-standing choice. Trimble Accubid is the other established standard with AI symbol detection, and ConEst IntelliBid is strong for low-voltage, datacom, and solar.
What is the best commercial electrical estimating software?+
Commercial electrical subcontractors need plan takeoff, NECA labor hours, and a Schedule of Values for GC submission. ScopeTakeoff is built for that workflow, with Division 26 assemblies for devices, conduit, gear, and lighting, conduit-to-wire calculation, labor stored as hours, and SOV output. McCormick and Accubid also serve commercial electrical with deeper catalogs aimed at larger shops.
How do you estimate an electrical job?+
To estimate an electrical job, count devices and fixtures off the plans, measure conduit runs by size and length, derive the wire inside each run from the conductor count and a makeup allowance, then apply NECA-style labor hours per device, per 100 ft of conduit, and per 1,000 ft of wire. Material and labor are kept on separate rails, a burdened composite labor rate converts hours to dollars, and commercial work is summarized as a Schedule of Values for the GC. Electrical estimating software automates the device counts, conduit-to-wire math, and labor-hour calculation.
What are NECA labor units?+
NECA labor units are standardized installation labor hours published in the NECA Manual of Labor Units, expressed per device (each), per 100 feet of conduit, and per 1,000 feet of wire, usually in Normal, Difficult, and Very Difficult columns. Electrical estimators apply these hours, then adjust with labor factors for site conditions before converting to dollars at a burdened labor rate. ScopeTakeoff stores labor as editable hours in this structure so you can start from NECA-style defaults and tune them to your crews.
Is there electrical estimating software for Mac?+
Yes. Many specialist tools like McCormick and Accubid Classic are Windows-oriented, but web-based platforms run on Mac. ScopeTakeoff is fully web-based and works in any browser on Mac, PC, tablet, or mobile, with nothing to install — so Mac-based electrical estimators can do takeoff and bidding without a Windows machine.
How much does electrical estimating software cost?+
Pricing varies widely. ScopeTakeoff is $100 per person per month with no annual contract. McCormick is reported to start around $300 per month with tiered quote-based pricing and implementation fees, Accubid Classic is listed around $2,000 one-time with Anywhere quote-based, and ConEst IntelliBid is quote-based. Excel is free if you already have Microsoft 365.
Can Excel be used for electrical estimating?+
Yes. Excel can be used for electrical estimating, especially for simple or low-volume bids. The downside is that device counts, conduit-to-wire math, NECA labor-hour application, and SOV output all require manual setup and ongoing maintenance, which becomes error-prone as bid volume grows.
