Need guidance: How to start a business while still working a full-time job?

Here’s the reality: you don’t quit your job to start a business—you earn the right to quit by proving you can get customers first.

What you should do instead (practical path)

Build income on the side first (non-negotiable)

If your current job blocks your schedule, you still have:

• Early mornings
• Evenings
• Weekends

That’s enough to validate demand. You don’t need 40 hours—you need consistent paying jobs.

Focus on quick jobs, quick cash, not perfect branding.

Get your first 5–10 jobs manually

Forget fancy marketing at the start. Do this:

• Post in Nextdoor / local Facebook groups (“We’re working in your area this week…”)
• Reply to people already asking for help
• Knock a few doors where work is obvious
• Ask friends, past contacts, coworkers

Your only goal: prove strangers will pay you.

Stack cash, not risk

Don’t quit until you hit at least one of these:

• You’re making 50–70% of your job income consistently for 2–3 months
• Or you have 2–3 months of expenses saved + jobs booked ahead

Right now, you’re trying to jump the gap without a bridge.

Create leverage before quitting

Once you see traction:  

• Line up jobs for 2–4 weeks ahead
• Raise prices slightly (test demand)
• Build repeat clients

That’s when quitting becomes a calculated move, not a gamble.

The uncomfortable truth

You don’t need permission from your job—you need discipline to use your off-hours. A lot of people say “my job won’t let me,” but what they mean is “I’m exhausted.” That’s real—but it’s also the price of transition.

You’ve got two kids. That means your plan has to be boring and reliable, not risky and exciting.

I would agree that starting a business and keeping it going is a process, but also has to be a labour of love to justify the extra time and effort needed to be successful. 

One thing I would add to what Roger said, is also to consider the types of customers you are targeting. At 6 years in I would say I am still somewhat early days haha but in my earlier days I built a relationship with another business that deals in lots of the small jobs (in my case as a plumber/gas fitter that meant replacing peoples faucets and toilets) simple in and out like Roger is saying, quick money. This one relationship was enough for me to make my transition to my own business. Even though the pay for it hasn't always been top end, it has been good in that it has been a consistent source of work and I have also spun off a bunch of other jobs from it. Getting in front of those people for something small and demonstrating your knowledge and personality positions you well to make jumps to something bigger with that customer. Quick example that comes to mind, I turned a $150 job into more then $10k in work with 1 customer. Bottom line would be to explore options to work with businesses that may need your service on an ongoing basis, and that can help make something that feels risky, not risky.

Well - Roger pretty much summed it up , not sure what more anyone  can say following that type of info he just gave you.

Make a commitment to make a certain number of cold calls / day and sign enough contracts needed to quit your job.

Man I was in the exact same spot as you — full time job, kids, wanting to go out on my own but scared I wouldn’t have enough work.

Here’s what actually worked for me:

Start now, while you still have a steady paycheck. Work nights and weekends. Use your current job to pay the bills while you build up customers on the side. Once you’re consistently booked 2–3 weeks out and have some money saved up, then make the jump.

Most people who quit their job first and then try to get customers end up stressed and going back to work.

Slow and steady is the way. You don’t have to go all in on day one.

Wow, All of the GPT Comments are right on they are giving you the recipe for it. but they don't hit how hard it actually is from the legality of incorporating to taxes Licensing, and continuing education,  to juggling family and home life.

I Started my construction company in 2021 working on the weekends and now it has grown to where the weekends aren't cutting it any more. scaling is the game and the catch is to not scale too fast. keep your head on a swivel and watch out for the customers that you know are going to hurt, if they are just coming to you to under cut someone else then they aren't the customer that you want. Keep your morals high and your pricing higher. You'll make more money and work less by being picky. 

Make sure you and your significant other have the same goals and are on the same page, check in often and have open communication. trust is number one, set time aside for family and be present while around them. 

And if you Base your business around Service and Helping Solve a problem you will go a lot further than just trying to stack cash. 

Good Luck with everything.

I am still on my journey, and I will tell you, don't quit your job unless you can survive at least six months without it, even then, that's risky. I left my job and jumped right into starting my business, and that led to some hard lessons, some might say are necessary but for someone who has been through it, I wish I could go back and start differently.

First, pretend you don't have a job, how are your finances today, what are you spending on, what do you truly need. I'm someone who would order out all the time, buy food that would sometimes sit in the fridge so long I had to throw it away. Movies, games, heck even just doing simple things like giving someone a ride, you need to start questioning every cent you spend. I got a chest freezer in the garage, I buy bulk from Costco now, if I want fast food on very rare occasion when I am not cooking then I pick it up. You need to discipline yourself like you have no money, because at some point, you may not. Build that muscle memory now, not when you are in the thick of it.

Your business, do it first while your employed, not just as some hobby, but as a second job, where you are on the clock and people expect results. You don't know the pressure of those first jobs, are you spending too much on materials, are you doing the right steps, are you sure you even want to do this. To get those first jobs you have to find the customers, that trial and error you want to do while you have the cash flow to do it. Calibrate on those, how much did that customer cost you trying to find them, how fast did you find them, what was your actual profit. Then see how you get the next 9, use that information to help understand your cashflow, your actual material cost and usage, and get reviews from actual customers. 

Paid leads will help you get those first customers, but you don't want that to be your only avenue. You want google, its free, its organic and you are not competing with other contractors who paid for the same lead, who will most likely bid lower as they want the job, not to spend money and get nothing. Google is a combination of length you been around, your reviews and your website SEO. The number one is reviews, you need them, not just reviews, but 5 star reviews with pictures. I cannot stress enough about reviews with pictures, the ones with pictures are 10x more important to google then those without.

One last tip, this is just how I got my head around costs. Make a debit account for the business, even if you don't have your LLC yet, just make a personal one you just use for business. Put your starting capital in there, everything you do for the business, you take from here, everything you earn for the business, put in here. It's a pipe dream when you think of profit, what you calculated in your head is not the number, its less. Gas, sundries, toll roads, you name it, it all pecks away at that account, and nothing shows you better on how much you actually spent and made then that month end account balance.

It's a struggle, but now that I am past my major ones I am glad I started my business, and I wish you the best with yours.

I'd be careful about going all in before you've built a steady pipeline of work.

A lot of successful business owners start by taking on jobs evenings and weekends, building referrals, and testing what actually brings in customers before leaving their full-time job.

The goal isn't to quit first and hope it works. The goal is to create enough demand that the business starts deciding for you.

With two kids depending on you, I'd focus on reducing risk while building momentum.

Title: What is one mistake you made when you first started your home service business that you'd tell a new business owner to avoid?

Hi everyone! 👋

I'm a newer business owner and one thing I've learned is that there is always something new to discover. I'd love to hear from those of you who have been in business for a while.

If you could go back to your first year in business, what is one mistake you would avoid or one piece of advice you wish someone had given you?

Whether it's pricing, customer communication, marketing, hiring, scheduling, or operations, I think your experiences could help many of us who are still building our businesses.

Looking forward to learning from everyone. Thanks in advance for sharing your wisdom!
