What Is a Contractor?

A contractor is a person or business that provides specific services for other companies or individuals. They work independently, not as permanent employees.
Think of it this way: You hire them to do a job. They complete it. Then they move on to the next project. Contractors bring specialized skills to solve problems or complete tasks. They might work for a few weeks, months, or even years on a single project.
Here’s what makes contractors different from regular employees:
- They work on a project basis
- They set their own schedules (usually)
- They handle their own taxes and benefits
- They can work for multiple clients at once
Pretty straightforward, right?
Types of Contractors
Not all contractors are created equal. Let me show you the main types you’ll encounter.
Independent Contractors
These are solo professionals who work alone. They might be:
- Freelance writers creating content for websites
- Graphic designers making logos and marketing materials
- Consultants giving expert advice to businesses
- Web developers building websites and apps
General Contractors
These contractors manage entire construction projects. They:
- Hire and coordinate other contractors
- Oversee the whole project from start to finish
- Handle permits and inspections
- Make sure everything gets done on time and on budget
Subcontractors
Subcontractors work under general contractors. They focus on specific trades like:

- Landscapers for outdoor design and maintenance
- IT specialists for computer networks and security
Key Responsibilities of a Contractor

What exactly do contractors do every day? Their responsibilities vary, but here are the common ones:
Project Planning
Every successful project starts with a solid plan. Contractors look at what needs to be done and estimate how long it will take. They figure out what materials and tools they need, then create timelines and milestones to keep everything on track.
Executing the Work
This is where the magic happens. Contractors use their specialized skills to complete tasks and solve problems as they come up. They make sure quality standards are met while documenting their progress throughout the project.
Client Communication
Good contractors are also good communicators. They update clients on project status and explain technical details in simple terms. They handle questions and concerns while providing regular progress reports to keep everyone informed.
Managing Resources
Contractors often juggle multiple resources at once. This includes time management across different projects and budget tracking to stay profitable. They also handle equipment maintenance and procurement, plus team coordination if they have helpers working with them.
But here’s something most people don’t realize.
Continuous Learning
The best contractors never stop learning. They stay updated on industry trends and learn new techniques and technologies. Many attend training sessions and workshops to adapt to changing regulations and standards in their field.

How Do You Become a Contractor?
Thinking about becoming a contractor yourself? Here’s how to get started.
First, you need to be really good at something. Get formal training, learn through apprenticeships, or build skills through practice. Many contractors earn certifications to prove their expertise.
Being a contractor means running a business. Register your business, get proper licenses, and set up insurance. You’ll also need to handle your own accounting and taxes.
Most contractor work comes through referrals. Connect with other professionals in your field and build relationships with potential clients. Create a website, build a portfolio, and ask satisfied clients for testimonials.
How to Work With a Contractor
Ready to hire a contractor? Here’s how to make it work smoothly.
Do Your Research
Not all contractors are equal. Take time to research before you hire anyone. Check their credentials and licenses, then read reviews from previous clients. Ask for references and actually call them to verify their insurance coverage and work quality.
Get Everything in Writing
Handshake deals can lead to headaches. Make sure you have a detailed contract that outlines the work, along with clear timelines and milestones. Include payment schedules and terms, plus change order procedures for any modifications.
Communicate Clearly
Good communication prevents most problems. Be specific about what you want and ask questions if something isn’t clear. Provide feedback throughout the project and address concerns immediately when they come up.
Set Realistic Expectations
Remember, contractors are professionals, but they’re not magicians. Quality work takes time, and changes to the original plan will affect cost and timeline. Weather and other factors can cause delays, and good work costs more than cheap work.
Benefits of Hiring a Contractor
Why should you hire a contractor instead of doing it yourself or hiring employees? Here are the main advantages.
- Contractors bring years of experience and have professional tools you don’t own
- You save money by avoiding employee benefits, office space, and training costs
- They offer flexibility to scale up or down without long-term commitments
- Good contractors carry insurance and handle permits to reduce your risk
- Outside contractors bring fresh ideas and creative solutions to your problems
Common Myths About Contractors (And the Truth)
Let me clear up some misconceptions about contractors.
