How to start a construction business (and survive year one)

The nine steps to launch a contracting company, with the financial groundwork that tackles the cash‑flow problems that sink most new construction firms.

Starting a construction business takes more than a license and a truck. You need a business plan, the right licenses and permits, insurance, bonding, and enough working capital to cover payroll and materials while you wait for draws. Roughly half of new construction companies close within five years, and well over half are gone by year ten — usually because they run out of cash, not customers or craftsmanship, according to BLS-based construction survival data.

This guide walks through the nine steps to start a construction company — and the financial setup that lets you bid, win, and survive the gap between doing the work and getting paid for it.

9 steps to start your construction company

Step 1: Write a construction business plan

A construction business plan answers four questions: what kind of work you'll bid, who your customers are, how you'll staff and run jobs, and what the numbers look like for the first one to three years. It doesn't have to be long. It does have to be specific enough that a bank, a surety, or a backer can read it and say yes.

Construction is a fragmented industry with very different economics by segment. A residential remodeler, a commercial general contractor, and a specialty subcontractor all operate in construction — but their overhead, bid cycles, and working-capital needs look nothing alike. Decide which one you are before you write anything else.

What to include

• Company overview: Legal structure, owners, location, licenses you'll hold, trades you'll self-perform vs. sub out
• Service lines: New construction, remodel, tenant improvement, ground-up, service and repair — the mix drives your pricing model
• Target customers: Homeowners, property managers, general contractors (if you're a sub), developers, public agencies
• Competitive landscape: Who else bids your work and where you win (speed, price, specialty trade certifications, relationships)
• Staffing plan: Which trades you hire in-house, which you sub, union vs. non-union, prevailing-wage work
• Startup costs and year-one revenue forecast: Tools, vehicles, insurance, licensing, working capital — plus the revenue and margin you realistically expect
• Billing model: Fixed-price, time-and-materials, cost-plus, or unit-price — each has different implications for how and when you get paid

Where most plans go wrong

First-time contractors underestimate working capital. You can't invoice until work is in place, owners often take 30 to 60 days to pay, and subs and suppliers expect payment on their own terms. The plan has to model the cash-flow gap, not just the profit margin.

Step 2: Register the business and get an EIN

Registering your construction business means picking a legal structure, filing with your state, and getting a federal Employer Identification Number (EIN) from the IRS. An LLC or S-corp is typical; the right choice depends on how you want profits taxed, whether you have partners, and whether you plan to seek bonding or outside capital.

Why structure matters

• Sole proprietor: Simplest to set up, but your personal assets are on the hook for anything the business does
• LLC: Shields personal assets, passes profits through to your tax return, works for most startup contractors
• S-corp: Potential self-employment tax savings if profits clear a certain threshold; more admin overhead
• C-corp: Usually only if you're raising outside capital; double taxation is a drag for most contractors

Talk to a CPA before you pick. Construction has revenue-recognition rules (completed contract vs. percentage of completion) and tax elections (Section 460 for long-term contracts) that your structure should support, not fight.

What you'll need

• State business entity filing (articles of organization or incorporation)
• EIN from the IRS (free, online, takes minutes)
• State tax registration and any local business licenses
• A DBA filing if you're operating under a trade name

Step 3: Get licensed at the federal, state, and local level

Construction licensing rules vary by state, by city, by trade, and by project size — and starting work without the right license is the fastest way to lose a job, pay penalties, or get barred from bidding.

Three levels to check

• Federal: If you'll bid on federal projects, you need a System for Award Management registration and, for most work over a certain contract value, compliance with the Miller Act (which requires payment and performance bonds)
• State: Most states require a general contractor license, a specialty trade license (electrical, plumbing, HVAC, roofing), or both. Requirements typically include an exam, proof of experience, proof of insurance, and financial statements
• Local: Cities and counties often require a separate business license and may require pulling permits through a registered contractor of record

Check your state's contractor licensing board website for the specific requirements. A good accountant or construction attorney can walk you through it — spending a few hundred dollars here beats finding out you need a fresh exam six months into operations.

Step 4: Secure insurance and start building bonding capacity

Insurance and bonding are two different things that both get lumped under "what you need to work." Insurance protects you. Bonds protect the people who hire you. Most of your early bids will require proof of both.

Insurance you'll likely need

Bonding capacity, not just bonds

A surety bond guarantees you'll perform the contract and pay your subs. A surety underwriter sets your bonding capacity — the total value of bonded work you can carry at once — based on your balance sheet, liquidity, backlog, and project history. You don't need bonding capacity to work as a residential remodeler. You absolutely need it to bid public work or commercial projects of any size.

You can start building bonding capacity before you have any. Open your books to a surety broker, show clean financials, demonstrate working capital discipline, and keep your balance sheet strong.

Step 5: Set up construction accounting

Construction accounting is job-based, not period-based. You track revenue, cost, and profit per project (sometimes per cost code within a project), not just month-by-month. That's what lets you see which jobs are making money, which are bleeding, and which are going to bust before they do.

What makes it different

• Job cost accounting: Every expense — labor, materials, subs, equipment, overhead allocations — is coded to a job and cost code so you can compare actual to estimate
• Revenue recognition: Long-term contracts usually use percentage-of-completion (recognize revenue as work progresses) or completed-contract (recognize at the end). The choice affects taxes and financial statements
• WIP (work-in-progress) reporting: A WIP schedule shows, per active job, the contract value, cost to date, estimated cost to complete, percent complete, and over- or under-billing
• Retainage: A percentage of every invoice (often 5 to 10 percent) that the owner holds until the job is complete — you book it, but you don't collect it for months
• Chart of accounts: Construction charts of accounts have job-cost, retainage, and over/under-billing accounts that standard small-business charts don't

Software choice

Most construction startups begin with QuickBooks Online or Xero for general ledger and add construction-specific layers (job costing, certified payroll, AP) as they grow. Mid-market contractors migrate to Sage Intacct, Sage 300 CRE, Viewpoint Vista, Foundation Software, or Acumatica when reporting complexity or project volume outgrows entry-level tools. Pick a system you can grow into for 3 to 5 years.

Step 6: Open business banking and a corporate card

Separate banking and a corporate card program are two of the cheapest wins you can set up on day one. They keep personal and business funds clean, make tax and audit prep easier, and — if you pick the right card — give your crews a way to buy materials from the field without burning personal cash.

What to open

• Business checking account: For deposits and operating expenses
• Business savings or money-market account: For holding retainage and emergency reserves
• Corporate card program: For crew purchases, supplier payments, fuel, and per-diem spend
• Line of credit: Even a small one, early — it's easier to qualify when you don't need it

Why the card matters more than you think

Construction is a field-first industry. Crews buy materials at supply houses, fuel at gas stations, and meals on the road. If you're running that through a personal card and reimbursing, you lose visibility into job costs in real time and spend the first two weeks of every month chasing receipts.

A corporate card program with controls by job, cost code, and crew lets purchases show up tagged and coded the moment they happen.

Step 7: Plan for the cash flow gap (this is where most startups fail)

Construction is a negative-working-capital industry for most contractors for most of a project's life. You pay payroll every two weeks, materials on 30-day terms, and subs on progress billings. Your owner pays you 30 to 60 days after you invoice, and holds retainage for months after that. The gap between money out and money in is where year-one contractors go under.

Where the gap comes from

• Payroll and sub payments go out weekly or biweekly
• Material purchases often net 30, sometimes COD until you establish credit with a supplier
• Owner payments net 30 to 60, often longer on public projects
• Retainage (typically 5 to 10 percent) sits until substantial completion — sometimes a year out
• Draw schedules can shift if the architect or owner is slow approving pay applications

How to close the gap

• Front-load the schedule of values so earlier line items bill higher (legitimately — talk to your estimator about how to do this without unbalanced bids)
• Negotiate supplier terms aggressively; net 45 or net 60 with key suppliers dramatically improves the gap
• Invoice the day work is in place, not monthly, where the contract allows
• Release retainage mechanically — track due dates, request releases on time, don't leave money on the table
• Keep a working-capital line of credit sized to at least one payroll cycle plus one month of material spend
• Use supplier credit (net terms) instead of card float for large material buys when rates are comparable

Financing options ranked by founder cost

Factoring is the last stop for a reason — it works, but the effective cost compounds quickly if you make it your default. Get the cheaper options set up first.

Step 8: Bid your first jobs and track costs by job

Winning bids at the right price is the hardest thing a first-year contractor learns. Bid too high, you don't win. Bid too low, you win and lose money. The discipline is in separating estimating (what the job should cost) from pricing (what you charge for it) and in tracking actual cost against estimate in something close to real time.

Build a bid the same way every time

• Take off quantities from the plans and specs
• Price labor, materials, equipment, and subs line by line
• Apply overhead and profit (as separate line items, not a blended percentage)
• Add contingency for unknowns — tighter on well-defined scopes, wider on renovations and ground-up work
• Review against historical job costs (if you have them) before submission

Track actuals the same way every time

Every purchase, labor hour, and sub payment gets coded to a job and cost code on the day it happens. At month-end (or better, weekly) you compare actual to estimate per cost code, flag anything over, and decide whether to issue change orders or absorb the variance. Job cost discipline from day one is the single biggest predictor of which contractors are still in business at year three.

Step 9: Grow without outrunning your working capital

More work is the goal. But the fastest way to go from profitable to insolvent is to double your project volume without doubling your working capital. Growth has to be paced against your cash position, your bonding capacity, and your operations bandwidth.

Signals you're outgrowing your working capital

• You're consistently using your line of credit to make payroll
• You're pushing supplier payments past terms to manage cash
• Your backlog is climbing but your bank balance is flat
• You're winning bigger jobs than your bonding capacity supports

What to do about it

• Raise bonding capacity in lockstep with backlog — talk to your broker before you need it
• Build cash reserves equal to at least one payroll cycle plus one month of overhead
• Refuse (or sub out) jobs you can't cash-flow, even if they look profitable on paper
• Reinvest in systems — accounting, job costing, AP, and payroll — before you hire more crews
