Turn Electrical Blueprints Into Cash: The AI Takeoff Side Hustle

Bobyard, a San Francisco takeoff company, raised a $35M Series A led by 8VC in December 2025 and launched an electrical takeoff product in June 2026. Counting outlets, fixtures and wire runs from drawings is now a venture-funded category. A solo version of that service is possible, but the numbers below show it earns modest money, needs real electrical-estimating knowledge, and competes with the software vendors themselves.

What is the AI electrical takeoff opportunity?

An electrical takeoff is the count of every device, fixture and wire length on a set of drawings, and it is the slowest part of bidding a job. Contractors who cannot get through the counting leave jobs unbid. Wells Electrical's Randi Clark said as much in Bobyard's launch release, paraphrased here: the company passes on jobs because it lacks time to bid them.

Who pays: small and mid-size electrical contractors and lighting distributors with more bid invitations than estimator hours. Why now: vision models can read drawings, and vendors say they cut the counting time. Bobyard says its customers report an average 65 percent reduction in takeoff times, though the release does not say this applies to electrical work, and its product page gives a 50 to 90 percent range. Both are company claims with no cited study.

The service you would sell is simple: a contractor sends drawings, you return a reviewed count in a spreadsheet, usually within a day.

How much can an AI electrical takeoff side hustle make?

On the assumptions below, roughly $900 a month part-time, about $4,500 at a medium scale and about $8,500 at a large one, before income tax. These are example estimates, not predictions. No published market rate for freelance electrical takeoff exists that we could cite, so every price is an assumption you would need to test with real contractors.

Formula: jobs per month × price per job − software − other costs − paid review time.

The $37.86 hourly figure is the BLS median for cost estimators in May 2025. The Togal.AI price comes from ConstructConnect's July 2026 comparison, according to ConstructConnect.

Where it falls short: at the small tier, if each job takes you 1.5 hours, eight jobs is 12 hours of work for about $900, before taxes. The medium and large tiers assume steady customers, which you do not have on day one. Treat the large column as a ceiling that depends on winning repeat contractors, not a typical outcome.

For a price anchor, Drawer AI publishes what its own concierge service charges its customers. Power device detection is $0.28 per device for counts up to 500, so a 400-device job would be about $112 if the whole count is billed at that rate. The page does not say how tiers apply. That is a vendor price for a service available only to its customers, but it shows that a $150 to $350 human-reviewed price needs to cover more than raw counting.

Which companies are already doing this?

Six companies show the range, from a funded software platform to a two-person startup. None is a template you can copy with $5,000, so the table separates what they did from what you can do.

The pattern: Drawer and Beam already sell the done-for-you layer. Your edge would be a narrow niche, faster turnaround for a handful of local contractors, or knowledge of a specific job type such as tenant fit-outs.

What did the funded companies do that a $5,000 side hustle cannot?

They built their own detection models and sold software to many customers. Bobyard says its models are trained on millions of drawings, and Drawer says it launched with six electrical contractors already using the product. Both are company statements.

With $5,000 to $50,000 you buy a seat of existing software, learn it, and sell your time with a quality check. You are an estimator with a tool, not a software company. Bidflow's own pitch shows where the human fits: it describes the AI as an assistant, not a replacement, with the estimator reviewing the AI's mistakes.

Do you need a licence or certification?

A takeoff service counts quantities on drawings. It does not install, design or stamp electrical work, so the electrician licence rules that govern the trade are a different question from the rules for selling an estimating service. Requirements for business registration, local licences and any professional rules differ by state and city, so check your state's business filing office and local clerk before taking money.

Two practical limits. Do not present yourself as a licensed electrical contractor if you are not one. And BLS notes that construction cost estimators typically have a bachelor's degree or several years of construction experience. Estimating is a skill, and "no experience needed" does not describe this work.

How much does it cost to start?

Software is the main cost. Prices below are as of July 2026 from ConstructConnect unless stated.

A realistic first-year outlay is the software plus insurance and registration, which is a few thousand dollars on the software side alone. Bidflow offers a 7-day free trial, but its product covers commercial lighting only, and its site says it excludes receptacles, general power, panels and risers.

How do you start an AI electrical takeoff business, step by step?

1. Learn to read electrical plans. Take the symbol legend, panel schedules and lighting schedules seriously. If you have never estimated, work with a mentor or take a course first.
2. Pick a niche. Choose one job type: commercial lighting, tenant fit-outs or residential remodels.
3. Choose software and trial it on real plans. ConstructConnect advises trialling AI features on your own plans, not a scripted demo, because some tools are calibrated for architectural floor plans and perform poorly on MEP drawings.
4. Learn the correction workflow. Find out how easy it is to fix AI-generated counts before they reach the estimate.
5. Build three sample takeoffs from public or permissioned drawings, with counts in a clean spreadsheet.
6. Set a test price. Quote a flat fee per job and a rush rate, then adjust after five jobs.
7. Offer a free sample to five local electrical contractors, the way Bobyard runs a live takeoff on a prospect's own project.
8. Register the business and get insurance per your state's rules.
9. Deliver in 24 hours and review every count by hand. Drawer's concierge team does a quality check on the AI results before returning them, so you should too.
10. Convert to a retainer for contractors who bid weekly.

Which free tools and resources can you use?

Few good takeoff tools are free, so budget for a paid seat. Use free tools for everything around it.

How can you use AI, and how do you scale it faster?

Where AI fits. AI does the first-pass count, and you do the review. Vendors describe lighting counts, receptacles, switches, circuits, panels and wire routing as the automated parts. Bobyard says each detection carries a confidence score and the estimator verifies it before locking it in. Outside the count itself, you can use a general AI assistant to draft emails and proposals and to summarize spec sections, with you checking the output. Costs for those tools vary.

Scaling. Move from per-job fees to monthly retainers, then add a part-time reviewer. The large column in the math assumes two software seats and paid review hours at the BLS median hourly wage.

Marketing channels worth testing are direct outreach to local electrical contractors and lighting distributors, and a free sample takeoff. Where it breaks: a single seat of software and your own hours cap at a few jobs a day, and a contractor who grows may simply buy the software and bring the work in house.

What are the risks?

The biggest is that the tool you resell is the product. Contractors can subscribe to Togal.AI, STACK or eTakeoff directly, and vendors such as Drawer and Beam sell the done-for-you service. BLS also says that estimation software is expected to reduce demand for cost estimators, with employment projected to fall 3% from 2025 to 2035.

Second, accuracy. A miscount can cost a contractor the job or the margin. Bidflow's YC page says that every missed symbol can cost thousands, and you carry that risk. Write limits of liability into your terms and ask an attorney to review them.

Third, general business risk. According to the Bureau of Labor Statistics, 53.9% of construction establishments born in March 2013 were still operating five years later, and 40.1% after ten. Those figures count all closures, including sales and retirements, and cover construction firms rather than estimating services.

This is research, not legal, tax or financial advice. No income is guaranteed.

What's still unclear?

• Market price. There is no published market rate for freelance electrical takeoff.
• Accuracy. Bidflow's 99% is a company claim on its YC page. Bobyard gives no numeric accuracy figure. There is no independent test.
• Scope of speed claims. Bobyard's 65 percent figure also appears in its Series A post attributed to landscaping customers, and it is not clear it holds for electrical.
• Product scope. Bidflow's YC page describes electrical symbol counting generally, while its product site scopes to commercial lighting.
• Funding. Bidflow has not disclosed its funding.
• Weakest point of the argument. The service layer is the part vendors are also selling, so a side hustle works best as a niche, relationship-driven business.
