That's why I'm a huge advocate of always starting a side business while working full-time, so that you can test your way into your new product or service, get feedback, validate the business idea, and start generating income before you quit your job. If you can master the art of scaling a side business idea while keeping your day job, you'll have no trouble succeeding once you're fully self-employed.
I've long been drawn to the passive income supplied by creating an ebook and publishing an accompanied print-on-demand paperback. By using platforms like KDP and CreateSpace, both by Amazon, you can create an easily create and sell an ebook that costs nothing to produce, and a paperback that earns you money only when it sells, removing much of the prior friction it took to get published.
I have worked as an SEO and digital marketing consultant for over 10 years and booked side gigs ranging from $500 to over $100,000. This has been by far my most successful side hustle. And even though SEO has become more of a commodity service – it feels like everyone and their mother does SEO these days, I have built a referral network that continues to generate new clients.
It’s funny that you put baking of all things on this list. I’d often considered the idea of baking cookies and things and selling them on Facebook garage sale sites and things like that – until I made Christmas cookies last week and found out how difficult it is. Let’s just say it gave me a healthy appreciate for the people who make all the tasty desserts I regularly enjoy!

Using your skills for profit is a common trend with all of the best side business ideas. If you're an expert at something, there's likely an audience of people online who would be willing to pay to become an expert in your field—just like you. If you want to take your skills and turn them into an online course that teaches others how to get the same results you've achieved in your life, career, or business, start with How to Create an Awesome Online Course on Udemy, where instructor Miguel Hernandez covers how he makes over $90,000/yr teaching online. You'll learn from more than 8 hours of video instruction.
With made-to-order fashion going mainstream, this industry is fueling a lot of side hustle opportunities. If you know how to mend clothes, then you have a growing market of budget-conscious and personalization-obsessed customers readily available. As long as you can get your hands on a commercial-grade sewing machine, start by offering to partner with local drycleaning and laundry services in exchange for referral fees every time they send you a new customer.
If you enjoy writing, find a topic you’re passionate about and start a website dedicated to covering that topic and anything else interesting you want to talk about. All you need is a computer, some time, and some energy to consistently write. It can start as a hobby and turn into a business over time. And blog hosting can cost less than $12 per month.
However, it’s important to understand that working from home doesn’t mean relaxing in your pajamas all day. In fact, you will probably end up working more from home than in-office. And be careful when searching online for remote work, though. There are an estimated 60 to 70 scam jobs for every genuine one. Only use vetted sites such as FlexJobs to ensure you’re not being taken advantage of.
Selling real flowers is where things can get tough. Many people already have a green thumb, and often they already supply flowers to friends and family. You will need to figure out which flowers will survive the shipping process, and decide how great of a distance you are willing to deliver across. Again, clear, attention-grabbing images will be key for successful selling.
I can’t say enough about dog walking and pet sitting. I’ve been doing this for over two years, and my business has grown to the point where I was only home 4 days last May. The place I’m at now has a pool, and the next place has a pool table. I love dogs but can’t have one of my own, so I also get all the puppy snuggles I could want. And the startup cost is very low.
