One point to keep in mind: since 2026, the social contribution rate for micro-entrepreneurs in BNC has risen to 25.6%, which reduces the net income on each billed mission. Therefore, reaching 100 euros net requires billing approximately 135 euros gross. To explore other avenues, you can see how to earn 100 euros quickly on Clarivox in a supplementary guide.

1. Microservices on ComeUp: Sell a Skill Today
ComeUp (formerly 5euros.com) allows you to offer services starting from a few euros: text writing, logo creation, video editing, voice-over. The principle is simple: you set your price, a buyer orders, you deliver.

The advantage over international platforms like Fiverr is the French-speaking clientele, which reduces the language barrier. Three to five orders are often enough to reach 100 euros if the service is well positioned in a specific niche.
2. Cumulative Cashback via iGraal or Poulpeo
Cashback sites return a percentage on your online purchases made through their link. The earnings per transaction remain modest (a few percent of the amount), but they add up on regular expenses: groceries, subscriptions, equipment.
Cashback does not generate additional income, it reduces your existing expenses. To accumulate 100 euros, a substantial volume of purchases or several months of patience is required. This method is better suited as a complement to another tip.
3. Paid Surveys on Toluna or Swagbucks
Answering online surveys earns between a few cents and a few euros per questionnaire. The compensation depends on the duration of the survey and the respondent’s profile. Platforms like Toluna, Swagbucks, or LifePoints offer regular surveys.
The earning ceiling remains low: reaching 100 euros generally requires several weeks of daily participation. Surveys function as supplementary income, not as a primary source.
4. Selling Unused Items on Vinted or Leboncoin
Clearing out a closet or garage can yield 100 euros in just a few days. Vinted focuses on clothing and accessories, while Leboncoin covers a broader spectrum (electronics, furniture, books). The speed of sale depends on the price set and the quality of the photos.
Setting a price slightly below market value speeds up the sale. Checking the prices of similar products already sold on the platform provides a reliable benchmark before posting an ad.
5. Freelance Web Writing on Malt or Upwork
Web writing remains one of the most in-demand freelance skills. Platforms like Malt (French-speaking market) or Upwork (international) connect writers and clients. A blog article or product sheet can be billed between a few dozen and several hundred euros depending on length and specialization.
With a background in SEO and a good command of French, two to three articles may be enough to exceed 100 euros. The micro-entrepreneur status is necessary to bill legally.
6. Website and App Testing on TestingTime
Companies pay users to test the ergonomics of their websites or applications. Platforms like TestingTime or Testapic offer paid testing sessions, often between 10 and 50 euros for a session lasting 30 to 60 minutes.
The number of tests available varies based on your demographic profile. Sessions are less frequent than surveys, but the pay per hour spent is significantly higher.
7. Selling Photos on Shutterstock or Adobe Stock
If you have a recent smartphone or a camera, selling photos on stock image sites like Shutterstock or Adobe Stock generates a long-term passive income. Each download earns a modest commission, but the accumulation over a catalog of several dozen photos can reach 100 euros over time.
The most sought-after subjects: landscapes, professional portraits, everyday objects on a neutral background, scenes of remote work.
8. Affiliate Marketing via a Blog or Instagram Account
Affiliate marketing involves recommending a product or service via a tracked link. Each sale generated earns a commission. Amazon, Awin, or CJ Affiliate offer programs accessible without a minimum traffic volume.
Making 100 euros through affiliate marketing requires an existing audience or the ability to create content that attracts organic traffic. Without an active blog or community on social media, the time to reach this threshold can be long.
9. Online Tutoring on Superprof
Superprof, Preply, or Italki allow you to give online lessons in school subjects, languages, or specific skills (music, coding). Prices vary based on the subject and the teacher’s experience.
A few hours of lessons are generally enough to reach 100 euros. Scientific subjects and foreign languages are among the most in demand. Video conferencing (Zoom, Google Meet) eliminates geographical constraints.
10. Audio Transcription on GoTranscript or Scribie
Transcription involves converting audio or video files into written text. GoTranscript and Scribie recruit French-speaking transcribers, paid per minute of audio transcribed. Fast typing and good spelling are the only prerequisites.
- Compensation depends on the difficulty of the file (number of speakers, sound quality, technical vocabulary)
- One hour of audio typically requires three to four hours of work for a beginner
- Files in French are less numerous than those in English, which may limit the volume of available missions
Each of these ten methods for earning 100 euros online presents a trade-off between the time invested and the regularity of earnings. Active activities (freelancing, tutoring, transcription) pay faster. Passive incomes (affiliate marketing, photos, cashback) take longer to start but require less daily effort once launched. The choice depends on your available skills and the timeline you set for yourself.
