12 Best Online Business Ideas With Low Investment You Can Start With Less Than $100

Honestly, you don’t need a lot of money. At all.

I used to think you needed like $10,000 to start a business. I was so wrong. So wrong.

My first business? I started with $47. Literally just a domain and Canva. That’s it. It made $200 in the first month. Not huge. But proof.

Let’s be real. If you have a laptop and wifi, you have 90% of what you need. The rest is just picking one idea and starting.

I spent weeks testing stuff. A lot of it was trash. But some worked. So here are the best online business ideas with low investment that I would actually tell my brother to start in 2026. No guru stuff. Just real.

For example, I already tried some of these low-cost AI business ideas myself, and they actually paid me before I even had a website. So this list is legit.

1. Freelance Writing – People Pay For Words

Do you write okay? Like, not even perfect. Just okay?

Brands will pay you. Every single website needs articles. They are too busy or too lazy to write. So they pay strangers on the internet.

You can charge $50 for 500 words as a beginner. Later? $300. Easy.

How to start? Make 2 sample articles on Google Docs. Create a Fiverr gig. Done. Zero dollars needed. You just need to start typing. Think about it: someone got paid to write what you are reading right now.

2. Print On Demand – No Boxes In Your Room

I love this one. Seriously.

You make a cool design. Like “Dog moms are cool” or something funny. You upload it to a site. When someone buys a T-shirt with that design, the company prints it and ships it. You get the profit.

You never touch the shirt. No inventory. No post office line. My friend does this. He makes like $800 a month just from stupid meme shirts.

Use Printful and Etsy. Both are free to start. Use Canva for design. This is easily one of the best online business ideas with low investment if you are even a little creative.

3. You Become The AI Guy For Local Shops

Local businesses are confused. They hear AI everywhere. They don’t know how to use it.

You can be the guy who helps them. Offer simple stuff. Like writing their Instagram captions with AI. Or setting up a simple AI chatbot that answers “what are your hours?”

They will pay you $200 a month for this. And the AI tool costs you maybe $20. So profit is huge. The thing is, they are not paying for the tool. They are paying for you not to make them learn it.

4. Short Video Manager – The TikTok Person

Business owners are like 40, 50 years old. They don’t get TikTok. But they know they need it.

So you become their TikTok person. You make 3 short videos a week for their shop. You just use CapCut. Use trending sounds. Add text.

That’s it. Charge $400 per client. Get 3 clients? That’s $1200. From your phone.

Crazy, right? But it works. Businesses are desperate.

5. Sell Notion Templates – Make Once, Sell Forever

People are obsessed with being organized. Or trying to be.

They buy planners. Digital planners. Budget trackers. Student dashboards. Content calendars.

You can make one in Notion in like 3 hours. Watch one YouTube video. Then sell it on Etsy or Gumroad for $19.

You make it once. It sells while you sleep. I have one template. Made it 8 months ago. Still makes like $15 a day. Best passive thing ever.

If you want more ideas, I saw this huge low-investment business ideas list by Shopify – they have like 50+ ideas there, pretty solid for beginners.

6. Virtual Assistant – Get Paid To Be Organized

Are you organized? Like, do you reply fast? You keep your calendar clean?

Founders will pay you for that. They are super busy. They need someone to manage emails, book meetings, and do research.

You can start at $15 an hour. No degree needed. Just be reliable. My cousin started 4 months ago. She now makes $25 an hour. Works 4 hours a day.

This is probably the most stable option in this whole list of the best online business ideas with low investment. Not sexy. But stable.

7. The $10 Newsletter

Pick one small topic you love. Not broad. Small.

Like “3 cheap flight deals every Friday” or “one AI tool for students daily” or “healthy 5-min recipes”.

Start a free newsletter on Beehiiv. It’s free. Write 2 times a week. Once you hit like 1000 people reading, you add a paid plan. $10 a month for extra stuff.

People will pay. Why? They don’t have time to search the internet. You do it for them. They pay for curation.

8. Teach What You Already Know

You know English? You can teach.

You know math? You can teach.

Parents in the US pay $30 an hour for a tutor online. For real. They pay that much.

You don’t need a certificate. You just need to explain well. Go to Preply. Make a profile. Or just post in Facebook mom groups. “I teach English for $20/hr”. You will get messages. I promise.

We all know something valuable. Just sell it.

9. UGC Creator – Brands Pay For Your Real Videos

UGC means User Generated Content. Big word. Simple meaning.

Brands don’t want fancy ads now. They want a real person in their bedroom saying “I love this face cream”.

They send you the product for free. You make a 30-second video on your phone. No fancy lights. They pay you $100 for that video.

You need 0 followers. Like, zero. They don’t care about your followers. They want the video to run as their ad. Think about it: you get paid to make TikToks.

10. Build And Flip Small Websites

This sounds hard. It’s not.

You buy a domain for $12. Like “bestcattoysreviews.com”. You use AI to write 10 articles. You put some free images.

Wait 2 months. Get a little traffic from Google. Then go to Flippa.com and sell it for $600. People buy them.

Then repeat. It’s like flipping houses but online. And way cheaper. This is one of those best online business ideas with low investment that not many students know about yet.

11. Faceless YouTube Channel

You don’t have to show your face. Thank god.

You can make a channel about scary stories. Or finance facts. Or history facts. Use an AI voice. Use free stock videos from Pexels. Edit in CapCut.

Upload one video daily. After you hit monetization, YouTube pays you every month. $500, $1000, even more. It takes like 2-3 months of work. But after that? It’s passive.

So slow at first. Then fast.

12. Set Up Second Brains In Notion

This is new. Super new.

Busy people have notes everywhere. Apple Notes, WhatsApp, Google Docs. Messy.

You can offer to organize their whole life in Notion. You call it “Second Brain Setup”. Charge $350 one time.

You can learn Notion in a weekend. Free on YouTube. Then sell the service. I saw people charging $500 for this on Twitter. And clients pay. Because their brain is messy and you make it clean.

This is honestly the future. And it’s one of the best online business ideas with low investment because your only investment is your time to learn.

So Which One Now? Stop Overthinking.

Look, don’t try to do all 12. Please don’t.

Pick ONE. The one that made you go “oh, I could do that” while reading.

Give it 30 days. Just 30. Work on it 2 hours a day. That’s it.

You will learn more in those 30 days than in 1 year of watching YouTube videos about business.

You can literally start today with less money than you spend on pizza.

Once you pick an idea, you can follow this official guide to launch your business from the SBA – it shows the legal steps simply.

You got this. Seriously.
