What are the benefits of starting a business while working full time? 

Most people think having a full-time job is an obstacle to entrepreneurship. They couldn't be more wrong. Your job isn't holding you back – it's your secret weapon. Here's why: But how do you start a business while employed? Let’s find out.  Woman Using Laptop

How to start a business while working full-time

You CAN start a business while working full time. We’ve done it, and so have our clients.  Just ask Kathryn, one of our clients who followed this exact approach. She was stuck with a boss who made her work life miserable. Everyone told her she was crazy to think about starting her own business. Eight months after working with us, she walked away from her toxic job into her own thriving consulting business. Now, let me show you exactly how to do the same (without overworking).

1. Find a business idea (without starting from scratch)

Here's the #1 mistake most aspiring entrepreneurs make: They think they need some revolutionary, never-before-seen idea. The truth? The best business for you is hiding in plain sight. That's how Carey and I discovered our business. We weren't productivity experts with fancy certifications. We were just two burned-out professionals who figured out how to reclaim our time and lives. When friends saw our transformation, they begged us to show them how we did it. That demand for good productivity coaches became Lifehack Method – our multimillion-dollar business. Your action plan:
  1. Write down 3-5 skills you already have that solve problems for others
  2. Ask yourself: “What do people constantly come to me for help with?”
  3. Test your idea by offering to help friends or colleagues with this skill
  4. Research similar businesses – if they exist, that's GOOD (it means there's demand!)
Remember: Your ideal business leverages what you already know while solving a problem people will gladly pay to fix.

2. Set goals that actually move the needle

Let me be brutally honest: Starting a business while working full-time will test your limits. Without crystal-clear goals, you'll quickly lose momentum and motivation. Whether they’re long-term or weekly goals, your goals must be SMART – Specific, Measurable, Achievable, Relevant, and Time-bound. But more importantly, they must excite you enough to get you working after an exhausting day at your regular job. List that shows how to plan your week For example: Weak goal: “I want to create a successful membership community.”  Strong goal: “I will create a membership community with 150 paying members in the next 12 months.” Then break that down into actionable milestones: 💡 Pro tip: Write your goals somewhere you'll see them daily. The visual reminder will keep you focused when all you want to do is watch Netflix after a long day.  Get more tips for setting goals in this video: 

3. Create a business plant that actually works

You know what you want to do – but you need to know how you’re going to get there. In other words, you need a business plan. It doesn’t have to be long, confusing, or formal. Think of it as a roadmap to guide you and keep you focused.  It should cover these five essentials:
  1. Your offer: What specific product or service are you selling, and what makes it different?
  2. Your ideal customer: Who needs your solution most desperately? Where do they hang out online and offline?
  3. Marketing strategy: How will you consistently get in front of your ideal customers? Pick just 1-2 channels to start.
  4. Sales approach: How will you convert interested prospects into paying customers? Make this process as simple as possible.
  5. Revenue goals: What specific numbers do you need to hit each month to make this sustainable?
Keep this plan to 1-2 pages max.

4. Get your finances in order (before you actually need to)

Did you know that nearly 40% of entrepreneurs lose sleep over money worries? Don't let that be you. Financial stress is the #1 killer of promising businesses. Here's how to prevent it: Start budgeting like a business owner: Track every dollar and identify expenses you can cut to invest in your business. Even $100/month adds up to $1,200 annually – enough to cover essential business tools. Separate business and personal finances immediately: Open a business bank account even if you're just starting. This simple step will save you countless headaches during tax season and give you clear visibility into your business performance. Know your funding options: While the average business costs around $40,000 to launch, you can start many online businesses for under $1,000. Consider these funding sources: 💡 My advice: Start as lean as possible. Validate your idea before investing heavily – many of our most successful clients started with just a laptop and a few hundred dollars.

5. Focus on the most important tasks

When you're building a business while working full-time, every minute counts. And you can get much more done every day – and use that time to build your business.  However, you’ll need to prioritize the most important tasks.  To do so, use the 1:4:5 rule to create an effective to-do list: How to write effective to-do lists But here's the real secret: leverage. Ask yourself: “What one task will make everything else easier or unnecessary?” For example, spending two hours creating an email template might save you 10 hours of writing over the next month. That's leverage. Finally, don't just list tasks – schedule them. Block specific time chunks in your calendar for business-building activities and protect those blocks ruthlessly. We discuss leverage in this video: 

6. Find time for your side business

“I don't have enough time” is the #1 excuse I hear from aspiring entrepreneurs. But the truth is, you have more time than you realize – you just need to know where to look (and no, you don’t have to burn out in the process). Here's how to find those hidden hours: But here's the game-changer that helped me scale faster than I thought possible: stop doing everything yourself. Carey and I wasted countless hours doing tasks that others could handle better and cheaper. Once we started outsourcing, our business growth exploded. Start with these high-impact areas for delegation: Tasks to outsource Even on a tight budget, you can find affordable virtual assistants and freelancers on platforms like Upwork or Fiverr. Remember: every hour you buy back is an hour you can invest in growing your business. Carey will walk you through delegation in this video: https://www.youtube.com/watch?v=RwtUbF7K4xQ When you start a business while working full time, it needs to be above board. Here's how to protect yourself: First, thoroughly review your employment contract. Look specifically for: Keep your business and day job completely separate: It’s a good idea to consult an employment attorney. One hour of legal advice now can help you get a lot of questions answered and stay safe.  💡 The smart approach: If your business idea directly competes with your employer, consider pivoting to a different niche or checking in with your boss or HR department.  To learn more about legal considerations, check this guide

8. Transition to a full-time business

The biggest mistake new entrepreneurs make is quitting their job too soon. Financial pressure can force you to make desperate decisions that damage your business long-term. Here's how to know exactly when it's safe to make the leap:
  1. Your business consistently generates at least 75% of your current salary for 3+ consecutive months
  2. You have 3-6 months of living expenses saved in an emergency fund
  3. You've eliminated or significantly reduced high-interest debt
  4. You have a clear 90-day plan for scaling your business post-transition
When these conditions are met, it's time to plan your exit. Give proper notice, leave on good terms, and focus on making your business your primary income source. Remember: patience here pays enormous dividends. The extra 3-6 months at your job provides the financial runway to make strategic decisions rather than desperate ones. Now you know how to start a business while working full time. Keep reading to find out what kind of business you can launch.

FAQ: Starting a business while working full time

Is it possible to work full-time and run a business?

Yes! In fact, 44% of people who start new businesses do it while working for an employer. You just need to manage your time and priorities effectively and stay consistent in leveraging your nights, weekends, and free time. 

What side hustles pay the most?

The highest-paying side hustles include consulting and coaching, which can help you make several thousands of dollars per month on the side. Freelancing can also help you tap into your existing skills and get paid for them. 

What are the tax implications of starting a business while working full time? 

Your business WILL be taxable, but the tax rate will vary based on location. And remember, you can also deduct certain business expenses like marketing, software, and home office costs.  I recommend keeping business and personal finances separate and working with an accountant to ensure compliance and maximize tax benefits. Read more about taxation on the IRS website.
