# How to start a subcontracting business

Getting work

Put the company identity, licensing checks, insurance, cash plan, and estimating process in place before taking work.

You want a trade business that can quote work, pay its bills, and complete what it promises. Define the work you will sell and the name you will contract under. Confirm licensing, banking, and insurance. Build a pricing method and test the setup on a job you can manage.

The licensing and insurance examples here are from NC. Ask your accountant, attorney, insurance agent, and licensing board about your business.

## Define the work your subcontracting business will sell

Write down what the company will sell. Identify the trade package, customer type, travel area, crew arrangement, and work you will decline. Decide who estimates, supervises, invoices, and handles return visits.

Describe how the company will run at the start. Do not base it on employees you have not hired or equipment you have not secured. If you plan to supply labor only, say who provides materials, lifting, access equipment, and consumables.

Choose the type of builder you want to work with before making a sales list. Show detailed finish work if that is what you sell. Show repeated rough-in packages if those are your work. For the operating tradeoffs, read [custom versus production builder work](/guides/custom-vs-production-builder-work/).

List what could keep you from starting. Check unresolved licensing questions, insurance exclusions, gaps in supervision, and cash shortages for the proposed work. Resolve those before promising a start date.

## Choose the entity and contracting name

Review ownership, liability, tax treatment, and administration with your advisers. The [SBA explains that business structure affects liability, taxes, and registration](https://www.sba.gov/counseling/launch-your-business/). Do not select a structure from a social post or assume every subcontractor must form an LLC.

Choose the name you will use on the subcontract. Match it across the bank account, tax records, insurance, and licensing applications. Record any trade name separately so you can explain the relationship to a builder.

For NC general contracting, the [board says a license is valid for its named entity](https://www.nclbgc.org/faq-contractors/). Check the licensed name before applying or changing your business structure. Ask the board how that change affects your ability to bid and work.

Give one person responsibility for renewals and filing records. Keep a calendar with the source of each deadline. Avoid copying a deadline from another business whose entity or license differs from yours.

## Set up taxes, banking, and a cash calendar

Use the SBA's [launch checklist for registration, tax identifiers, and opening a business bank account](https://www.sba.gov/counseling/launch-your-business/). Confirm which federal and state registrations apply with your accountant. Arrange the account and recordkeeping process before collecting job payments.

Assign each job a name or number for estimates, purchases, timesheets, and invoices. File the job documents under that name or number. Decide how you will record owner contributions, reimbursements, payroll, and business purchases.

Have your accountant explain the records needed for tax filings and worker reporting. Avoid adopting a reporting threshold from an undated template. Confirm the rule for the payment year and arrangement in question.

Prepare a cash calendar as well as an estimate. Enter the dates you expect to buy materials, pay workers, submit an invoice, and receive payment. Use the actual proposed terms. Keep expected payments separate from cash you have.

## Confirm licensing for the proposed work

In NC, [G.S. 87-1 defines general contracting with a $40,000 threshold for covered undertakings and stated exceptions](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_87/GS_87-1.html). Ask the board to evaluate your actual role and scope. Do not assume that subcontracting or splitting a package resolves licensing.

Check the license requirements for your trade separately. The [electrical board publishes electrical license classifications](https://www.ncbeec.org/licensing/). The [plumbing and heating board covers plumbing, HVAC, fuel gas piping, and fire sprinkler contracting](https://nclicensing.org/).

Ask each applicable board what the company needs before bidding, contracting, or starting. Record the answer and its source. If you plan to expand into another state, check that state's requirements separately.

Before listing a license on your capability sheet, check that it covers your company and the work you offer. Keep a renewal record and assign someone to check changes.

## Arrange insurance and crew records

Give your insurance agent a written description of your work. Include employees, owners working in the field, hired businesses, vehicles, equipment, and expected projects. Ask the agent to review exclusions and the requirements in a sample builder subcontract.

NC's [Industrial Commission describes the general three-employee workers' compensation threshold and exceptions](https://www.ic.nc.gov/workers-compensation-claims/employers). Subcontracting adds a separate issue under [G.S. 97-19](https://www.ncleg.gov/EnactedLegislation/Statutes/HTML/BySection/Chapter_97/GS_97-19.html). Have the agent review who is on your crew and the contract with the builder together.

For worker classification, the [IRS evaluates control and the working relationship](https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee). Explain the working arrangement to your accountant or attorney before treating helpers as subcontractors. Prepare payroll and employment processes when applicable.

Separate “coverage arranged” from “builder requirements satisfied” in your checklist. Ask for written confirmation of open insurance questions. Do not sign a promise you have not reviewed with the agent.

## Build a price from the package

Build each estimate from your own costs. Use this worksheet as a template. It does not set market rates or a profit percentage.

| Cost line | What to enter |
| --- | --- |
| Field labor | Expected hours and your full labor cost |
| Materials | Quantities, quoted prices, delivery, and applicable taxes |
| Equipment | Rental, transport, operating costs, or allocated owned-equipment cost |
| Supervision | Site review, coordination, and quality checks |
| Mobilization | Travel, loading, setup, protection, and cleanup |
| Return work | Planned stages, punch work, and closeout |
| Business overhead | Your chosen allocation of administration and operating expenses |
| Risk and profit | Deliberate amounts based on the package and business plan |

Check the quantity basis. State who supplies each item and what would change the price. Use [the subcontract bid guide](/guides/how-to-bid-a-job-as-a-subcontractor/) to turn that estimate into a proposal.

Include the cost of your own labor in the estimate. Working without pay does not make that labor free on future jobs. Review the price with the cash calendar before accepting work.

## Set up the first builder account and job folder

Create a capability sheet with your actual scope, service area, assigned crew, and relevant experience. Get permission to share project photos and references. Put sensitive tax and financial records in a separate onboarding folder.

Ask a suitable builder for its qualification process. Review its contract, payment requirements, site readiness process, and change authority. Choose a first package with a clear scope and commitments you can meet.

Set up a job folder before mobilizing. Include the signed scope, plan revision, estimate, schedule assumptions, credential records, material orders, approved changes, and invoice instructions. Keep each approved document in one place.

At closeout, compare actual costs with the estimate. Check which tasks cost more or less than expected before changing future bids. Update the worksheet and decide whether the account fits your company.

After preparing the business, use [finding subcontracting work](/guides/find-subcontracting-work/) to choose a builder whose package fits your scope and crew.
