Before we get into the full estimating platforms, here are two free tools built for electricians. No signup, no software to install, works from your phone on the job site.
CloseCrew Wire Size Calculator
Wire sizing is a dual-constraint problem every electrician solves daily. The conductor must carry the load current without exceeding its ampacity after temperature and bundling derating. It must also deliver acceptable voltage at the load end over the run length. Get it wrong and motors fail to start, lights dim, and you're pulling wire a second time.
The CloseCrew Wire Size Calculator implements the full NEC screening procedure: 125% multiplier for continuous and motor loads, Table 310.16 ampacity lookup at your insulation and termination ratings, ambient and bundling correction factors, voltage drop using NEC Chapter 9 Table 8 resistance values, NEC 240.4(D) small-conductor OCPD limits, and equipment grounding conductor sizing from Table 250.122.
Enter load and circuit details. Set amperage or motor HP, voltage, phase, run length, and maximum voltage drop. Or use a quick-start preset for common circuits like EV chargers (32A, 48A), ranges (50A), or subpanel feeders (100A, 200A).
Set installation conditions. Choose insulation and termination temperature ratings, ambient temperature, and number of current-carrying conductors for NEC derating.
Review copper and aluminum sizes. Get the governing AWG/kcmil size for both copper and aluminum, adjusted ampacity after derating, recommended OCPD, and copper EGC per Table 250.122.
Use it to quote jobs accurately, verify plans before you pull permits, and confirm wire sizing before you open the conduit. It's the fastest way to go from "what size wire do I need?" to a code-compliant answer in the field.
CloseCrew Missed Call Cost Calculator
You sized the wire correctly. You built the estimate. The homeowner said they'd think about it. Then they called back while your crew was in a panel. The call went to voicemail. They called the next electrician in Google results.
Industry research shows electrical contractors miss 27-62% of inbound calls. Roughly 85% of callers who hit voicemail never call back. The CloseCrew Missed Call Cost Calculator puts a dollar amount on this problem.
The default electrical inputs show 45 calls/month, 32% miss rate, 28% booking conversion, and $650 average job value. The result: $31,450 in annual revenue lost. Every unanswered call is worth $182 in booked work on average.
The math behind it: missed calls x booking conversion rate x average job value. Defaults are sourced from industry benchmarks (WhatConverts, Dexcomm). Trade-specific presets available for HVAC, plumbing, and electrical.
This is where estimating and operations collide. You can price every job perfectly and still lose $31,000 a year because nobody answered the phone. We'll show you how to fix that later in this guide.
Before choosing a tool, understand the two categories:
Standalone estimating and takeoff software (Trimble Accubid, McCormick, ConEst, STACK, TurboBid, Esticom) handles one job exceptionally well: calculating material, labor, and overhead costs from blueprints and plans. These tools are disconnected from the rest of your operations. You'll need separate apps for scheduling, dispatching, invoicing, and accounting.
All-in-one field service platforms (BuildOps, Housecall Pro, Jobber, FieldEdge) include estimating as one module alongside scheduling, CRM, dispatching, and invoicing. The estimate data flows into the rest of your workflow without rekeying.
The tradeoff is clear. Standalone estimating tools go deeper on takeoff accuracy. All-in-one platforms go wider on workflow integration. Most electrical shops under $2M revenue get more value from an all-in-one platform. Shops doing high-volume commercial plan-and-spec bidding need a dedicated takeoff engine.
For service-side quoting (residential and light commercial): speed-to-quote, mobile use, good-better-best options, customer-facing proposals, integrated financing, and seamless invoicing after approval.
For commercial takeoff (plan-and-spec bidding): deep NEC/NECA assembly databases, on-screen digital takeoff, labor-unit accuracy, AutoCAD/BIM integration, and change order management.
Most shops under $2M revenue need service-side features. Most shops over $5M with dedicated estimators need commercial takeoff. Many shops in between need both, and the honest answer is using one tool for each job rather than forcing a takeoff engine to do field quoting or vice versa.
Here is where estimating software and business operations collide.
You invested in the right estimating tool. You're quoting faster. You're winning more bids. But what happens when a homeowner who received your estimate calls back at 7 PM to accept? If that call goes to voicemail, the job goes to the competitor who answered. Home service contractors miss:
You can't answer the phone when you're pulling wire through a wall. A full-time receptionist costs $35,000-$45,000/year plus benefits.
That's exactly the gap CloseCrew is built to close.
Larry doesn't just answer. He books.
Larry, CloseCrew's AI Employee, answers every call 24/7 with Voice AI that sounds like your best employee. He qualifies the lead, books jobs directly into your FSM calendar, sends text confirmations to reduce no-shows, and follows up on open estimates automatically.
Most AI stops at the answer. Larry goes further because he works inside the same system that runs your business. He has a complete view of every customer, job history, and past conversation. So Larry always knows who he's talking to and what to do next.
What the wrong tools cost you: Most contractors run on five disconnected tools. Leads that come in after hours go cold. Your team chases callbacks instead of running jobs. Revenue slips through the cracks between the estimate, the follow-up, and the booking. CloseCrew replaces all of that with one system.
What contractors are saying
Arctic Air: 30% more revenue in one year. Hired Larry, added a truck to their fleet.
Air Texas: Booked a $20,000 job after hours. Larry answered when no one else could.
Premier Heating and Air: Response time dropped from 12 minutes to under 1 minute. Converted 3x more leads.
Air Design: 13 extra appointments in the first 30 days. Estimate conversion went from 5-10% to near 100%.
Run the numbers for your own shop with the Missed Call Cost Calculator. Most electrical contractors discover they're losing $31,000+ per year in revenue from unanswered calls alone.
Your best employee doesn't take days off. Ready to hire Larry?
The right estimating software gets your quotes in front of customers faster. CloseCrew makes sure every callback, every follow-up question, and every "yes, let's do it" gets captured and booked, 24 hours a day, 7 days a week.
Getting started takes days, not months. White-glove onboarding within 48 hours. Data migration from your existing software. Staff training for your entire crew. We test and refine Larry until he reflects your business.
