Startup Guide

Starting a contracting business costs less than most people think to get licensed and legal, but more than most people plan for to actually operate until the money starts flowing. The contractors who struggle in year one usually underestimated the working capital they'd need to bridge the gap.
After years of doing the books for residential GCs, here's a realistic breakdown of construction business startup costs, including the expenses new contractors forget and the working capital that determines whether you survive your first year.
These are the one-time costs to become a legal, operating contractor.
Application fees, exam fees, and processing for your contractor license. Varies by state. Budget a few hundred dollars for fees, plus exam prep materials if you use them.
Most states require a surety bond. You don't pay the full bond amount, you pay an annual premium (a percentage based on your credit). Budget a few hundred to a couple thousand for the premium depending on credit.
Setting up an LLC or corporation. State filing fees plus optional legal or service fees. Typically a few hundred dollars.
General liability insurance, and workers' comp if you'll have employees. The first payment or down payment on annual policies. Budget based on your state and coverage.
If you don't already have them, the tools of your trade. This varies enormously depending on what you already own and what your work requires.
A work truck or van, if you don't have one. This is often the largest single startup cost, whether you buy outright or finance.
A simple website, business cards, signage, and a Google Business Profile. Can be modest to start.
Beyond startup, these recur and must be covered by your revenue.
Ongoing general liability and workers' comp. A significant monthly or annual cost.
Fuel, maintenance, insurance, and payments if financed.
Project management, accounting, and any subscriptions. Modern construction management software runs from free to $300+ per month depending on the platform.
Ongoing lead generation, whether that's online presence, advertising, or networking.
If you have employees or use subs, their costs. This is project-related but you need cash to pay them before customers pay you.
Bookkeeping, tax preparation, and the taxes themselves. Don't forget quarterly estimated taxes.
Working capital. This is what sinks more new contractors than any other single thing.
Here's the problem: in construction, you pay for materials and labor before the customer pays you. You buy the lumber, your crew works for two weeks, and you might not collect until a milestone payment or the end of the phase. That gap between when money goes out and when it comes in has to be funded by your working capital.
On a single job, you might need to float thousands of dollars in materials and labor for weeks. Run two or three jobs at once and the working capital requirement multiplies. Many new contractors get profitable jobs but run out of cash because they didn't have enough working capital to bridge the gap.
Plan for working capital. Before you start, have enough cash to cover materials and labor on your active jobs plus your operating expenses for at least a few months. This buffer is what lets you take jobs and operate while waiting to get paid. Underestimating it is the most common financial mistake new contractors make.
You don't need everything on day one. Prioritize.
You don't need an office, a fancy truck, or expensive software to start. Work from home, use the vehicle you have, and choose affordable tools. Keep fixed costs low until revenue is steady.
You need to estimate, track costs, contract, and invoice professionally, but you don't need to overpay. Platforms built for small residential GCs now start free, far less than enterprise tools. A free plan lets you start without upfront cost.
Buy the tools the job in front of you requires. Expand as the work demands it, not in anticipation.
A Google Business Profile, a simple website, and systematic review collection cost little and generate leads. Start here before paying for advertising.
This isn't a cost so much as a discipline, but it saves money. Knowing your real numbers prevents the expensive mistakes (underpricing, cash crunches, tax surprises) that drain new contractors.
Rather than a single number (which varies too much by trade, state, and what you already own), here's how to build your own estimate.
License fees + bond premium + business formation + initial insurance. Often $2,000 to $6,000 depending on state and coverage.
Tools you don't already have + vehicle (if needed). Ranges from minimal (if you're already equipped) to $30,000+ (if you need a truck and tools).
Website + Google profile + business cards + software. Often $500 to $2,000 to start, then ongoing software costs.
The big one. Enough to float materials and labor on your active jobs plus operating expenses for several months. This is highly variable but often the largest requirement. Plan for several thousand to tens of thousands depending on your job size and volume.
The legal and setup costs are modest. The vehicle and working capital are where the real money is. Plan the working capital carefully, because it's what determines whether you make it through year one. If you're earlier in the journey, start with how to become a general contractor, learn how to price a job, and once you're running jobs, the job costing guide keeps the numbers honest.
Phixmo gives a new contractor real-time job costing, invoicing, and change orders free forever, and Pro adds AI estimates, contracts, and e-signature from $169/month. Field workers are always free, so your startup overhead stays low.
It varies widely by trade, state, and what you already own. The legal and licensing costs are often $2,000 to $6,000. The bigger costs are a vehicle (if needed) and working capital to float jobs until you get paid. Many contractors need tens of thousands when working capital is included.
Usually the vehicle and working capital. Working capital especially is underestimated. You pay for materials and labor before customers pay you, and that gap must be funded. It's the most common reason new contractors run into trouble.
No. Most new contractors start working from home and keep overhead low. Avoid fixed costs like office space until your revenue justifies them.
Enough to cover materials and labor on your active jobs plus operating expenses for at least a few months. The exact amount depends on your job size and how many you run at once. Underestimating this is the most common financial mistake.
The legal setup is relatively affordable. You can keep startup costs low by working from home, using tools you have, choosing software with a free plan, and starting with free marketing. The unavoidable cost is working capital to fund your jobs.
