Starting or developing an online business no longer requires a large initial capital. The available tools allow you to test an idea in just a few days, sometimes in a few hours. However, you still need to choose the right approach based on your skills, budget, and the time you can dedicate. Here are ten concrete ideas, each with its mechanism and real constraints.
1. Micro-SaaS in no-code: create software tools without coding
Have you identified a repetitive task in your job or that of your acquaintances? No-code platforms like Bubble or Glide allow you to build a small web application and sell it as a monthly subscription. The model relies on recurring revenue, which stabilizes cash flow.
The main constraint is customer support. Even a simple tool generates requests as soon as it is used daily. Allocate time to respond, fix, and improve; otherwise, the churn rate can rise quickly.

2. Paid newsletter on a specific niche
The principle is simple: you write exclusive content sent via email each week to paying subscribers. Tools like Substack or Ghost manage subscriptions and payments. The launch cost is limited to your writing time.
The choice of niche determines the entire model. A newsletter on freelance taxation in France or on trends in the wine market attracts an audience willing to pay. A topic that is too broad dilutes perceived value and reduces the conversion rate.
3. Web accessibility compliance service for e-commerce merchants
Since June 28, 2025, the European Accessibility Act covers e-commerce services aimed at consumers. Navigation, product search, and the ordering process must meet specific criteria. Micro-enterprises providing services benefit from an exemption under certain conditions, but most online shops are affected.
Offering an accessibility audit and technical corrections represents a high-demand service. Most e-commerce merchants are still unaware of this regulatory obligation. You can train in web accessibility standards (WCAG) and sell targeted audits without material investment.
4. Digital products: templates, models, and ready-to-use kits
A Notion template for managing a freelance project, a Canva template kit for LinkedIn posts, a budget tracking spreadsheet: these products are created once and sold indefinitely. Marketplaces like Gumroad or LemonSqueezy handle distribution.
Why does this format work so well? Because the buyer saves time immediately. No training to follow, no learning curve. A good template solves a specific problem in under five minutes.
5. Audit and consulting in electronic invoicing
Since September 1, 2026, all businesses must be able to receive electronic invoices, according to the Directorate General of Public Finances. The obligation to issue invoices is being phased in. Many small structures have not yet adapted their tools.
If you are skilled in accounting or management software, you can offer remote support services. The need is concrete and urgent. This type of service sells well as a package, with a clear deliverable: the client company is compliant at the end of the mission.
6. Creation of chatbots compliant with the European AI regulation
More and more online shops and service providers are integrating chatbots to answer common questions. The European AI regulation requires that people be informed when interacting with a chatbot, unless this is clearly evident from the context.
Configuring a chatbot is no longer enough; legal compliance must also be ensured. Offering the design, configuration, and compliance of these virtual assistants constitutes a high-value service, especially for SMEs that do not have an internal legal department.
7. Online training on a technical skill
Do you know how to use video editing software, configure a server, or master a craft process? Turning this expertise into video modules sold on a platform like Teachable or Podia generates passive income after the production phase.
The key lies in specificity. A general course on “digital marketing” faces thousands of competitors. A course on “automating customer follow-ups with Make.com for artisans” targets a small but motivated audience.
- Identify a technical skill that you practice regularly and that others struggle to acquire on their own
- Structure the content into short modules (less than fifteen minutes each) to facilitate learning
- Add practical exercises: training with concrete deliverables has a significantly higher completion rate
8. Content curation service for executives
Decision-makers lack the time to keep up with news in their sector. Offering a weekly synthesized watch, delivered via email or through a shared Notion space, meets a real need. The model works on a monthly subscription basis.
The value lies in your ability to filter and prioritize information. Don’t summarize everything: select the three or four topics that really matter to your target audience, and explain why they matter.
9. Niche marketplace for local handmade products
Rather than selling your own products, you can create a marketplace that connects local artisans with online buyers. Solutions like Sharetribe allow you to launch a marketplace without custom development.
The main difficulty is getting started: you need to convince the first sellers to join the platform before you have buyers. Start with about ten artisans in a small geographic area, then expand once traffic stabilizes.
10. Support for creating an online business
If you have already launched a profitable web project, your experience has market value. Offering individual or small group mentoring, remotely, allows you to monetize your journey. The format can range from a one-off session to ongoing support over several months.
- Define a clear niche: supporting freelancers, artisans, career changers
- Set a measurable deliverable for each support (launching the site, first sale, administrative compliance)
- Document your client results to build your credibility
Each idea presented here is based on a different mechanism: recurring revenue, one-time sale, service provision, or commission. The best online business is one that leverages a skill you already possess. Test one idea, measure the initial results, then adjust before diversifying.
