Launching an online business involves choosing a business model, but also navigating a regulatory framework that has changed in nature over the past two years. Between the Digital Services Act applied since February 2024, the law of May 21, 2024, on the regulation of the digital space, and the classic obligations of the Consumer Code, compliance constraints weigh differently depending on the type of activity chosen.
Comparing these models in terms of entry costs, legal complexity, and margin potential allows for a more informed choice than a simple list of ideas.

Recent Legal Constraints for an Online Business in France
Most guides limit themselves to legal mentions and GDPR. However, the framework has been tightened on several simultaneous fronts, and these texts accumulate.
The Digital Services Act (EU Regulation 2022/2065) imposes since February 2024 obligations of transparency, content moderation, and management of systemic risks on platforms. For an entrepreneur selling through a marketplace or using affiliate marketing, this means stricter rules on targeted advertising and traceability of third-party sellers.

The law n°2024-449 of May 21, 2024 adds a national layer: combating illegal content, protecting minors, and strengthened regulation of influencer marketing. A business relying on acquisition through influencers or social networks must now document the compliance of its campaigns, under penalty of sanctions. The resources available on onebusiness.fr help better understand these obligations before launching.
These texts change the game for models highly dependent on social advertising or affiliate marketing. The cost of compliance is no longer negligible, even for a micro-enterprise.
Comparison of Online Business Models: Cost, Margin, and Complexity
The table below compares four common models, evaluated on three criteria that determine medium-term viability.
| Model | Entry Cost | Legal Complexity (post-2024) | Margin Potential |
|---|---|---|---|
| Sale of digital products (training, templates) | Low (hosting, payment tool) | Medium (right of withdrawal, VAT OSS for EU sales) | High (no stock, almost zero marginal cost) |
| Classic e-commerce / dropshipping | Medium (platform, stock or supplier, logistics) | High (product compliance, DSA if marketplace, customs) | Variable (margins compressed by competition) |
| Affiliate / monetized content | Low (website, content) | High (influencer law 2024, advertising transparency) | Medium (dependent on traffic and programs) |
| Freelancing / service provision | Very low (skill, portfolio) | Low (T&Cs, invoicing, micro-enterprise) | High (billing by time or project) |
Freelancing remains the model with the most favorable entry cost / margin ratio. However, it is the only one that is not scalable without hiring.
The sale of digital products combines a low entry cost with a high margin potential, but legal complexity has increased: the VAT OSS (One Stop Shop) regime applies from the first sale to a consumer in another EU country, requiring VAT to be declared in each member state via a single window.
The Case of Dropshipping After the DSA
Dropshipping accumulates constraints: compliance of imported products, final seller responsibility for safety, and transparency obligations strengthened by the DSA if the supplier is outside the EU. Margins, already compressed by competition, struggle to absorb these compliance costs.
Online Customer Acquisition: Three Levers to Balance
Developing an online business involves choosing one or two mastered acquisition channels, not a scattered presence on all fronts.
- Natural referencing (SEO) produces delayed but lasting results. The cost is mainly in content creation time. It suits high-margin models that can wait several months before generating qualified traffic.
- Paid advertising (Google Ads, Meta Ads) generates immediate traffic but weighs on margins. A product with a low average basket struggles to support an acquisition cost of several euros per click. Profitability should be calculated before launching the first campaign.
- Content marketing on social networks works for activities with a strong personal dimension (freelancing, coaching, training). However, the law of May 21, 2024, imposes increased transparency on commercial partnerships and sponsored content.
The balance depends on the chosen model. A freelancer selling a service for several hundred euros can afford a long acquisition cycle via SEO or LinkedIn. An e-commerce operator with an average basket of a few dozen euros needs rapid volume, which directs them towards paid advertising, with the associated margin risk.
Legal Status and Taxation of Online Business in 2024
The micro-enterprise remains the simplest entry status. Beyond the revenue thresholds set by regulations, transitioning to a company (EURL, SASU) becomes necessary.
A often underestimated point: the VAT exemption does not exempt from the OSS regime for sales of digital products to individuals in other EU countries. From the first euro sold to a German or Spanish consumer, the VAT of the destination country applies.
Social Charges and Contributions
In a micro-enterprise, social contributions represent about a quarter of revenue for service provisions. This rate, combined with the lack of expense deduction, makes the status less attractive as operating costs rise (advertising, tools, subcontracting).
The choice of status is not just an administrative formality. It conditions the ability to deduct expenses, charge VAT, and optimize remuneration. A poor choice of status can absorb the entire margin on a business with low unit profitability.
The French legal framework has caught up with the reality of online commerce. The most profitable models on paper are not always the ones that withstand the accumulation of obligations best. Before choosing between digital products, e-commerce, or freelancing, calculating the net margin after compliance remains the most reliable criterion.
