The question of how to make money online is more popular than ever.

But among all the promises of "getting rich quick", it's tough to determine which methods really work. In this comprehensive guide, we'll discuss 25+ proven ways to make money online, including realistic expectations, required investments, and practical tips to get you started today.

How to make money online through e-commerce

E-commerce is one of the most profitable ways to make money online. The Dutch e-commerce market grew to over €35 billion in 2025, and platforms like bol.com make it accessible for everyone to sell products. Below are the most important e-commerce methods.

1. Selling on bol.com

Bol.com is the largest online platform in the Benelux with over 13 million active customers. As a seller, you benefit from their enormous reach without having to build your own webshop. You can start with a small assortment and scale up as you gain experience. Use tools like the Product Tracker to discover profitable products and the Sales Dashboard to monitor your sales in real-time.

2. Dropshipping

With dropshipping via bol.com, you sell products without holding any inventory. Your supplier ships directly to the customer. This significantly reduces the financial risk, as you don't need to invest in inventory. Look for reliable European suppliers for fast delivery times and higher customer satisfaction.

3. Starting your own webshop

With platforms like Shopify, WooCommerce, or Lightspeed, you can set up a professional webshop within a day. Having your own webshop gives you full control over branding, prices, and customer relationships. Combine this with selling on bol.com for maximum reach.

4. Print on demand

Print on demand allows you to sell customized products (t-shirts, mugs, posters, phone cases) without holding any inventory. Designs are only printed after an order is placed. Platforms like Printful and Gelato integrate with your webshop and handle production and shipping.

5. Selling digital products

Digital products have no inventory costs, no shipping costs, and unlimited scalability. Think of e-books, online courses, templates, software, stock photos, or music. Once created, you can sell them endlessly - the ultimate form of passive income.

6. Handmade products on Etsy

Do you have a creative talent? Etsy is the ideal platform for handmade jewelry, art, clothing, home decor, and more. The marketplace attracts buyers who are willing to pay more for unique, handmade products.

How to make money online with freelance services

Freelancing is one of the fastest ways to make money online, as you can immediately utilize your existing skills. The demand for freelancers is growing globally, and Dutch freelancers earn an average of €50-€100 per hour, depending on their specialization.

7. Becoming a freelance writer

Content is king - and companies constantly need blog posts, articles, product descriptions, whitepapers, and social media content. If you can write well in Dutch or English, you can start immediately on platforms like Upwork, Fiverr, or Werkspot.

8. Graphic design

Logos, social media graphics, presentations, packaging designs - almost every business needs visual content. Tools like Canva, Adobe Creative Suite, and Figma make it possible to deliver professional work. Specialized designers earn €40-€120 per hour.

9. Web development and programming

Web developers are in high demand. Whether you're building WordPress sites, developing custom web applications, or creating mobile apps - the rates are high (€60-€150 per hour) and there's more demand than supply.

10. Virtual Assistant

As a virtual assistant, you help entrepreneurs with email management, calendar planning, customer service, data management, and other administrative tasks. This is a low-barrier way to get started without special training.

11. Online coaching and consulting

Do you have expertise in a particular field? Offer online coaching or consulting via Zoom or Google Meet. From business coaching to fitness, nutrition, career, or financial advice - clients are willing to pay for personal guidance.

Expected income per method

The following table provides a realistic overview of what you can expect from different online income methods. Keep in mind that results vary greatly depending on effort, experience, and niche.

Content creation and social media

Creating content is a growing industry. Dutch influencers and content creators are earning more and more through various income streams, from advertising revenue to sponsorships and their own products.

12. Starting a YouTube channel

YouTube pays creators through the YouTube Partner Program once you have 1,000 subscribers and 4,000 watch hours. Dutch YouTubers earn an average of €1-€5 per 1,000 views through ads, but the real income often comes from sponsorships and their own products.

13. Launching a podcast

Podcasts have exploded in popularity in the Netherlands. You can earn money through sponsorships, affiliate links, premium content, and your own products. Starting a podcast costs almost nothing - a good microphone (€50-€150) and free hosting software are sufficient.

14. Blogging

A blog can generate income through affiliate marketing, display advertising (Google AdSense, Mediavine), sponsored articles, and your own products. It takes time to build traffic, but once established, it provides passive income.

15. Social media management

Companies are constantly looking for social media managers to handle their Instagram, TikTok, LinkedIn, and Facebook. If you have an affinity for social media and know how to build engagement, you can earn €30-€80 per hour as a freelancer.

16. TikTok and Instagram Reels

Short videos are the fastest-growing content format. Creators earn money through the TikTok Creator Fund, brand deals, affiliate links, and promoting their own products. The reach you can build organically is enormous - even without an existing audience.

Building passive income online

Passive income is the ultimate goal for many online entrepreneurs. While 'passive' doesn't mean there's no work involved, there are methods that generate ongoing income with minimal maintenance after an initial time investment.

17. Affiliate marketing

In affiliate marketing, you promote other people's products or services and earn a commission per sale. You can do this through a blog, YouTube, social media, or email list. Popular affiliate programs in the Netherlands include the bol.com Partner Program, Amazon Associates, Coolblue, and TradeTracker.

18. Creating online courses

If you're an expert in a subject, you can create an online course on platforms like Udemy, Skillshare, or your own platform via Teachable or Kajabi. Courses on e-commerce, programming, design, and marketing are particularly popular. Check out the Zoloo offerings on our course page for inspiration.

19. Stock photography and video

If you have an eye for photography, you can upload stock photos to platforms like Shutterstock, Adobe Stock, iStock, or Pexels. Each download earns a small royalty, but with a large portfolio, this can add up to a significant monthly side income.

20. Writing books and e-books

Through Amazon Kindle Direct Publishing (KDP), you can self-publish e-books and paperbacks without a publisher. Non-fiction books on specific niches often perform best. Once published, they continue to sell without additional work.

Technical and specialized methods

21. SEO consultancy

Companies pay handsomely for search engine optimization. If you understand how Google works and can help websites rank higher, you can earn €60-€150 per hour as an SEO consultant. This is a skill you can learn relatively quickly through online resources.

22. App development

Developing mobile apps - whether it's SaaS tools, games, or utility apps - can be very profitable. With frameworks like Flutter and React Native, you can develop for both iOS and Android simultaneously.

23. Email marketing and funnels

Email marketing has an average ROI of 3600%. Companies are looking for specialists who can set up effective email campaigns, build automations, and optimize conversions. With tools like email campaigns from Zoloo, you can offer this to e-commerce clients.

24. Data analysis and market research

Using tools like the Product Database and Keyword Verkenner, you can provide valuable market insights to e-commerce entrepreneurs. Data analysts who conduct market research for online sellers earn an average of €50-€90 per hour.

25. Online tutoring

Offer online tutoring in subjects you're good at - math, languages, programming, or music. Platforms like Superprof, Bijlesportaal, and Tutorful connect you with students. Tutoring instructors earn an average of €20-€50 per hour.

Common mistakes when making money online

Before you start, it's essential to avoid these common mistakes that many beginners make:

Trying too many methods at once

Focus is essential. Choose one method, become good at it, build a stable income, and then expand to other methods. Trying to do everything at once won't get you anywhere.

Unrealistic expectations

Making money online isn't a "get rich quick" scheme. Most successful online entrepreneurs have invested months to years before building a substantial income. Patience and consistency are crucial.

Not investing in knowledge

Many people try to figure everything out themselves instead of investing in courses, tools, or mentorship. The right knowledge and tools - like the Winstcalculator for e-commerce sellers - can save you months of trial and error.

Ignoring taxes

In the Netherlands, you're required to report income from online activities to the tax authorities. Register with the KvK in time if you generate more than a side income. Use tools for automatic invoicing to keep your administration in order.
