7 Top Online Businesses You Can Start With Just $100 in 2025

Think you need thousands of dollars to start a real business? Think again. In 2025, some of the most profitable online businesses can be launched with nothing more than a hundred bucks, a laptop, and the drive to succeed. No warehouse required. No massive inventory. No crushing debt before you make your first sale.

The digital economy has leveled the playing field. While your competitors are waiting for the "perfect moment" or drowning in startup loans, you could be building something real—starting today, for less than the cost of a decent pair of shoes.

Here are seven proven online business models that entrepreneurs are using right now to generate real income, all starting with $100 or less.

1. Print-on-Demand Store: Design Once, Profit Forever

Startup Cost: $50-$100
Potential Monthly Income: $200-$5,000+
Time to First Sale: 1-4 weeks

Print-on-demand is exploding in 2025, and for good reason. The global print-on-demand market reached over ten billion dollars in 2024 and is projected to approach thirteen billion in 2025. Even more impressive, the market is anticipated to surge to approximately 103 billion by 2034, representing roughly 26 percent annual growth.

Here's why POD is perfect for beginners: you never touch inventory. When someone orders your custom t-shirt, mug, or tote bag, the POD company prints it, ships it, and you keep the profit margin. Your only costs are a domain name, minimal hosting, and your designs.

What You'll Need:

• Shopify or Etsy account (starting at $39/month or $0.20 per listing)

• Free design tools like Canva or Printful's Design Maker

• Integration with POD platforms like Printify or Printful

Average profit margins run between 40 to 45 percent on most products, according to data from successful merchants. That means if you sell a custom hoodie for $35, you might keep $15-$18 after the POD company takes their cut for production and shipping. Successful merchants typically maintain margins between 20 to 60 percent, with premium niches hitting the higher end.

The beauty of POD is scalability. Start with t-shirts, then expand into mugs, phone cases, tote bags, stickers, and home decor—all without buying a single product upfront. The most successful sellers upload at least ten new designs weekly and target niche audiences with specific interests rather than trying to appeal to everyone.

Pro Tip: Focus on profitable niches. Apparel accounts for nearly 40 percent of the market, but home decor, drinkware, and accessories are also strong performers. Black and white t-shirts, sweatshirts, and hoodies dominate global demand, so start there and branch out once you understand what sells.

2. Affiliate Marketing: Get Paid to Recommend Products

Startup Cost: $50-$100
Potential Monthly Income: $500-$10,000+
Time to First Sale: 2-6 months

Affiliate marketing is the art of getting paid to recommend products you believe in. You create content—blog posts, YouTube videos, social media posts—that includes special tracking links. When someone buys through your link, you earn a commission. No product creation. No customer service. No shipping headaches.

One blogger started Making Sense of Cents in 2011 with just 100 dollars, and has grown the site to generate 100 thousand dollars monthly from affiliate income and content monetization. That's not typical for beginners, but it shows the ceiling is incredibly high for those who stick with it and build an audience.

What You'll Need:

• A domain name and basic hosting ($50-$75 for the first year)

• Free affiliate programs (Amazon Associates, ShareASale, ClickBank, etc.)

• Content creation tools (free options like Google Docs, Canva, and social media platforms)

The key to affiliate marketing success is choosing a niche you understand and genuinely care about. Don't just chase high commissions—focus on products your audience actually needs. Create helpful, honest content that solves real problems, and the sales will follow naturally.

Pro Tip: Start with a simple blog or YouTube channel focused on one specific topic. Fitness equipment reviews, productivity software comparisons, cooking gadget recommendations—pick something you know well and can create content about consistently. SEO matters here, so learn basic keyword research using free tools like Google Keyword Planner or Ubersuggest.

3. Freelance Writing or Content Creation

Startup Cost: $0-$100
Potential Monthly Income: $500-$5,000+
Time to First Sale: 1-2 weeks

If you can write clearly and meet deadlines, freelance writing remains one of the fastest ways to start earning online. Businesses desperately need blog posts, website copy, product descriptions, email campaigns, and social media content—and they're willing to pay for quality work.

Freelancing has become a massive force in the economy. Freelancers contributed over one trillion dollars to the US economy in recent years, and remote work continues expanding with over 32 million Americans expected to work remotely by 2025.

What You'll Need:

• Free profiles on freelance platforms (Upwork, Fiverr, Freelancer.com)

• Portfolio samples (create 2-3 free samples in your niche)

• Basic website or LinkedIn profile showcasing your work (optional but recommended)

Your startup investment might include a professional domain and simple portfolio website ($50-$100) and maybe a few business cards for local networking. Everything else—finding clients, delivering work, getting paid—happens digitally and costs nothing.

Rates vary wildly. Beginners might start at $50-$100 per article, but experienced writers charge $200-$500 or more for the same work. The difference? Specialization and proven results. Writers who understand SEO, conversion copywriting, or technical niches command premium rates.

Pro Tip: Start by specializing in one industry or content type. Become the go-to writer for SaaS companies, fitness brands, or real estate agencies rather than being a generalist competing with everyone. Specialization lets you charge more and attract better clients faster.

4. Social Media Management Services

Startup Cost: $50-$100
Potential Monthly Income: $500-$3,000+
Time to First Client: 1-3 weeks

Small businesses everywhere know they need social media presence, but most owners have no idea how to do it effectively—or no time to do it at all. That's where you come in. If you understand how Instagram, Facebook, LinkedIn, or TikTok work, you can turn that knowledge into a profitable service business.

What You'll Need:

• Free scheduling tools (Buffer free plan, Later free plan)

• Portfolio of sample posts you've created

• Business cards and basic branding materials ($50-$100)

Start by offering your services to local businesses at a discount just to build your portfolio. A local coffee shop, gym, or boutique might pay $300-$500 per month for you to manage their social accounts, create posts, engage with followers, and run basic promotions. Land three clients at $400/month and you're earning $1,200 monthly—enough to quit a part-time job.

The best part? You can manage multiple clients' social media accounts from your phone during your commute, lunch break, or whenever you have spare time. No physical location needed. No expensive software required.

Pro Tip: Specialize in one platform and one industry. Become the Instagram expert for restaurants or the LinkedIn specialist for B2B consultants. When you focus, you learn faster, deliver better results, and can charge premium rates because you're seen as an expert rather than a generalist.

5. Resume Writing and Career Coaching

Startup Cost: $0-$50
Potential Monthly Income: $300-$2,000+
Time to First Client: Days to weeks

Everyone needs a good resume, but most people struggle to write their own. If you understand how to structure a resume, highlight achievements, and tailor applications to specific jobs, you can charge for that expertise.

Resume writers typically earn between 50 to 150 dollars per project, meaning just a few clients per month generates meaningful side income. One founder launched a resume writing service in 2018 for only five dollars and eventually built a business generating between 1,500 to 4,000 dollars monthly selling digital resume templates and services in over 50 countries.

What You'll Need:

• Free resume templates and design knowledge (Canva, Google Docs)

• Understanding of ATS (Applicant Tracking Systems) and resume best practices

• Free profile on freelance platforms or your own simple website ($50)

Start by offering your services on platforms like Fiverr or Upwork, or promote locally through LinkedIn, Facebook groups, and word-of-mouth. You can also create and sell resume templates on Etsy for passive income alongside your custom writing services.

Pro Tip: Expand into LinkedIn profile optimization and cover letter writing to increase your average order value. Instead of charging $75 for just a resume, offer a package with resume, cover letter, and LinkedIn optimization for $200. Clients get more value, and you earn more per project.

6. Digital Products and Template Sales

Startup Cost: $20-$100
Potential Monthly Income: $200-$5,000+
Time to First Sale: 1-4 weeks

Digital products are the ultimate passive income. Create once, sell forever. No shipping. No inventory. No physical production costs. Once you've created a digital planner, social media template pack, or productivity spreadsheet, you can sell unlimited copies with nearly 100 percent profit margins after platform fees.

What You'll Need:

• Etsy or Gumroad seller account ($0.20 per listing on Etsy, free on Gumroad)

• Design tools (Canva free plan, Google Sheets, PowerPoint)

• Payment processing (built into selling platforms)

Popular digital products include planners and organizers, social media templates for Instagram or Pinterest, business spreadsheets and trackers, printable art and wall decor, educational guides and ebooks, and Notion templates for productivity.

The initial work investment is higher than some other business models—you need to create quality products—but once they're live, sales can happen 24/7 without your involvement. Successful sellers create multiple products and build collections, so customers return to buy more.

Pro Tip: Start by solving a problem you personally faced. Created a meal planning spreadsheet that changed your life? Package it beautifully and sell it. Built Instagram templates that simplified your content creation? Sell the templates. The best digital products solve real problems for specific audiences.

7. Online Tutoring or Digital Courses

Startup Cost: $0-$100
Potential Monthly Income: $300-$3,000+
Time to First Client/Sale: 1-4 weeks

If you're knowledgeable in any subject—from math and science to guitar, cooking, or graphic design—you can teach others online and get paid for it. Online education has exploded, with people worldwide seeking affordable, convenient ways to learn new skills.

What You'll Need:

• Free platforms for live tutoring (Zoom, Google Meet) or course hosting (Teachable, Outschool, Skillshare)

• Basic knowledge in your teaching area

• Optional: simple course materials (PDFs, videos) created with free tools

For one-on-one tutoring, charge $20-$50 per hour depending on your subject and expertise. Elementary school tutoring might start at $20/hour, while specialized subjects like SAT prep, coding, or business consulting command $50-$100+ hourly.

For digital courses, create once and sell repeatedly. A $97 course sold to just 20 students generates nearly $2,000 in revenue. Platforms like Teachable and Skillshare make it easy to host and sell courses without technical knowledge.

Pro Tip: Start with live tutoring to validate demand and refine your teaching approach, then package your knowledge into a recorded course for passive income. This gives you both immediate cash flow and long-term scalability.

The Real Secret: Just Start

Here's the truth about starting a business with $100: the money isn't the real barrier—mindset is. Most people spend months researching, planning, and waiting for the perfect moment. Meanwhile, successful entrepreneurs start imperfect businesses and improve them as they go.

Every business model listed here has been proven by thousands of entrepreneurs worldwide. The market data shows explosive growth in these sectors through 2025 and beyond. The infrastructure exists. The customers are waiting. The only missing piece is your decision to start.

Pick one model that matches your skills and interests. Invest your $100. Launch within the next week—not next month, not when everything's perfect, but within seven days. Create your first product, publish your first content, or reach out to your first potential client.

Will you become a millionaire overnight? Of course not. But you could make your first $100 within a few weeks, your first $1,000 within a few months, and build a legitimate income stream that gives you flexibility, freedom, and options most people only dream about.

The best time to start was years ago. The second best time is right now. Stop waiting. Stop researching. Stop planning. Just start.

Your $100 business is waiting to be built. What are you going to create?
