How to start a field service business

To start a field service business, pick a trade and a tight service area, handle the legal setup with an accountant and attorney, price from your real costs, win your first customers locally, and run on simple systems until volume forces you to add more. The two numbers that decide whether it works are your break-even jobs per month and how much of each day goes to driving.

Most people who start a field service company are good at the work. That's the easy part. The business fails or succeeds on things nobody taught them in the trade: pricing, cash flow, scheduling and saying no to jobs that don't pay.

This guide walks through the steps in order. It doesn't replace advice from an accountant, attorney or insurance broker. Where those people are needed, it says so.

Step 1: Choose the trade and the work mix

You probably already know your trade. The real decision is the mix of work inside it:

• Repair and service calls. Fast cash, unpredictable demand, high drive time per dollar.
• Installation and replacement. Bigger tickets, longer sales cycles, more working capital tied up in equipment.
• Recurring maintenance. Predictable, lower ticket, builds a customer base you can sell to later.
• Commercial vs residential. Commercial pays slower and expects paperwork. Residential pays at the door and expects you on time. See commercial vs residential field service.

Many successful companies start with repair to generate cash and add maintenance agreements early so the slow months have a floor. The preventive maintenance scheduling guide covers how to run that work once you have it.

Step 2: Draw a tight service area

New owners almost always draw their service area too wide. Saying yes to a job 45 minutes away feels like growth. It's usually a loss.

The arithmetic is simple. Every minute of drive is a minute of paid time with no billable output. A wide area means fewer jobs per day, and jobs per day is what decides whether a truck pays for itself. See windshield time for how this adds up.

Start with a radius you can cross in about 30 minutes in normal traffic. Expand when you have enough demand inside it to fill days, not before. When you do expand, think in zones. See service territory.

Step 3: Set up the business properly

This is where you need professionals. Don't skip it, and don't take legal or tax direction from a blog, this one included.

• Business structure. Sole proprietorship, LLC, S corporation and others have different liability and tax effects. The U.S. Small Business Administration has a plain overview of business structures. Talk to an accountant before choosing.
• Licensing. Most trades require state or local licenses, and requirements vary widely by location. Check with your state licensing board and city or county.
• Insurance. General liability, commercial auto, and workers' compensation once you have employees. An insurance broker who works with contractors can tell you what your trade and state require.
• Bank account and bookkeeping. Separate business and personal money from the first day.
• Employees vs contractors. The tax and legal treatment is different. The IRS explains the basics in independent contractor or employee, and state rules can be stricter. Get advice before you hire or sub out work.

Step 4: Know your startup costs

Make a list before you spend. The SBA has a worksheet-style guide to calculating startup costs. For a field service company, the big categories are:

• Vehicle (purchase or lease, upfitting, shelving, signage)
• Tools and diagnostic equipment
• Opening inventory of common parts
• Licensing, insurance and registration
• Phone, website and basic software
• Working capital to cover expenses until customers pay

Working capital is the one people forget. If you do commercial work on 30 or 60 day terms, you'll pay for parts, fuel and wages well before the money arrives.

Step 5: Run the break-even math

Before you set prices, find out how many jobs you need just to stay open.

Break-even jobs per month = monthly fixed costs ÷ (average ticket − variable cost per job)

Fixed costs are what you pay whether or not you work: truck payment, insurance, phone, software, your own minimum draw. Variable cost per job is parts, fuel and anything else that only happens when a job happens.

These are made-up numbers. Use yours. The point is the comparison: if break-even is 2.1 jobs a day and your service area lets you do 3, you have a business. If your area only allows 2, you're working for free. The break-even labor rate calculator and the jobs per day calculator help with both sides.

Step 6: Price from cost, not from competitors

The most common startup mistake is pricing below cost because a competitor charges less. You don't know their costs, and they may be going out of business.

Build your rate from your own numbers: what an hour of your time actually costs once you count drive time, admin time and overhead, then add the margin you need. The field service pricing guide has the full method, including when to use flat-rate pricing versus time and materials, and whether to charge a trip charge.

Step 7: Win the first customers

Early customers usually come from a few places:

• People you already know, and former customers if you're leaving an employer (check any non-compete or non-solicit agreement with an attorney first)
• Local search, especially a complete Google Business Profile with photos, hours and service area
• Referral partners in adjacent trades, property managers, real estate agents and builders
• Neighborhood density. After a job, the houses next door are your cheapest leads. A finished job in a neighborhood makes the next job there easier to sell and cheaper to reach.

Track where every job came from. Within three months you'll know which sources are worth paying for.

Step 8: Use the simplest systems that work

On day one you need very little:

• A phone number that you or someone answers every time
• A calendar everyone can see
• A way to write up jobs with photos
• Accounting software for invoices and expenses
• A list of customers and equipment

That's a field service management system, even if it's three apps and a notebook. Add software when a specific problem forces it: missed calls, double bookings, lost paperwork, or not knowing which jobs made money.

The first function to outgrow a shared calendar is usually scheduling, around the time a second or third truck goes out. Once two people are booking jobs for several techs, nobody can see where every truck will be. That's the point to think about how travel fits into the times you promise. CrewLink is built for companies from 5 trucks up, so most companies hit that decision a little later.

Step 9: Make the first hire carefully

The first hire is a bigger change than the first truck. You go from doing the work to managing someone who does it.

Common first hires:

• A second technician, so you can spend more time selling, estimating and running the business
• An office person or answering service, so calls are answered while you're under a house

Before you hire, write down how you do each job type, what a complete job write-up looks like, and what you expect on arrival times and customer contact. That becomes your onboarding. See technician onboarding and the guide to managing field technicians.

Step 10: Decide when to add a truck

Add a truck when the current ones are consistently full with work inside your service area, not when you have a good week. A useful test: if you've been turning away or pushing out profitable work for six to eight weeks, and the backlog is inside your territory, the second truck has demand waiting for it.

Run the break-even math again with the new truck's fixed costs and a realistic ramp-up for the new tech. The scaling a field service business guide covers what changes from 1 to 5 trucks and beyond.

Common questions

How much does it cost to start a field service business?

It depends on the trade, whether you buy or lease a vehicle, and how much equipment you need. The main costs are the vehicle, tools, opening parts inventory, licensing, insurance and working capital. List each one with real quotes before you start rather than relying on general estimates.

Do I need a license to start a field service business?

Many trades require a state or local license, and some require several. Requirements vary by trade and location. Check with your state licensing board and local government, and confirm with an attorney if you're unsure.

How do I get my first customers?

Start with people you know, a complete local search listing, and referral partners in related trades. After each job, market to the immediate neighborhood. It's the cheapest lead you'll get, and nearby jobs also keep your drive time down.

How many jobs a day does a field service business need?

Enough to cover fixed costs. Divide monthly fixed costs by the contribution per job (average ticket minus variable costs), then by working days. That gives your break-even jobs per day. Your service area and drive times decide whether that number is realistic.

When should I hire my first employee?

When you're consistently turning away or delaying profitable work, or when time spent on calls, estimates and admin is costing you billable work. Write down your job standards first so the new hire has something to learn from, and get advice on employment law and payroll before hiring.
