EV Charger Install Quoting, Load Calc, and Permit Packet Software

The problem

An electrician quoting a home EV charger install spends one to three unpaid hours per job: driving to the property, photographing the panel, doing a service load calculation, guessing at the cable run, pricing materials, writing the quote, and later assembling a permit application for the local authority. Half those quotes never convert, so the wasted time is pure margin loss. Errors in the load calc or the permit packet cause failed inspections and callbacks.

Why now

EV charger install volume is climbing across the US, UK, Canada, and Australia as EV parc grows and utilities and grant schemes subsidise home and workplace chargers. Electricians are the bottleneck. Meanwhile vision models can now read a panel photo and extract breaker sizes and main breaker rating reliably enough to prefill a calculation that a licensed human then signs off on, which was not practical two years ago.

Who pays

Small electrical contractors and EV charge point installer firms with 2 to 25 electricians in the US, UK, Canada, and Australia, doing anywhere from 5 to 100 charger installs a month, currently quoting with spreadsheets and memory.

How it makes money

Per seat SaaS of $79 to $149 per electrician per month, or a per quote credit model for low volume firms. Upsell: white label homeowner facing quote page, and a lead marketplace where charger brands and utilities pay for qualified installs.

Market & demand

Order of magnitude: tens of thousands of electrical contractors across the four markets touch EV work, and only a subset specialise. A few thousand paying seats at roughly $100 per month is a mid seven figure ARR ceiling, with meaningful upside if the lead flow and marketplace layer works.

Vertical software for the trades has been a proven wedge (ServiceTitan, Jobber, Tradify), but those tools are generic scheduling and invoicing. The EV specific workflow, load calculation plus permit packet, is still done manually or in Excel. Utilities and charger OEMs increasingly want a certified installer network, which creates a natural distribution partner for whoever owns the installer workflow.

SWOT

Competition & the gap

Generic field service tools (ServiceTitan, Jobber, Tradify, simPRO), EV specific players such as Qmerit and Treehouse on the install marketplace side, and homegrown spreadsheets.

The wedge: Qmerit and similar players own lead routing but not the electrician's quoting and permitting workflow. Nobody has built the boring, code aware tool that makes an individual electrician faster on the exact task that costs them unpaid hours.

Go-to-market

Start in one jurisdiction with one code set so the calculation and permit templates are unambiguously correct. Sell direct to EV focused electrical firms found through charger OEM installer directories and local licensing registers. Publish free load calculation and permit checklist tools to capture organic search from electricians.

First 10 customers: Pull installer lists from public charger OEM installer directories in one metro, offer to do their next ten quotes for them inside the tool for free, and use the time saved figures as the sales pitch to the next twenty firms.

How to set it up

1. 1Choose a single launch jurisdiction and codify its load calculation rules and permit form fields
2. 2Build panel photo intake with a vision model that extracts main breaker rating and existing loads, always with human confirmation
3. 3Build the quote builder with materials pricing, cable run estimation, and branded PDF output
4. 4Generate a permit packet PDF matching the local authority template
5. 5Pilot with five electrical firms and measure quoting hours saved and win rate
6. 6Add a second jurisdiction only after the first is stable, then launch self serve pricing

How to validate it

Hours saved per quote, quotes created per seat per week, quote win rate lift, permit rejection rate falling, and firms adding seats without being asked.
