The micro-enterprise regime accounts for a growing share of business creations related to the web, whether it involves online sales, digital service provision, or content creation. Behind the apparent simplicity of this status, the legal obligations weighing on web auto-entrepreneurs remain numerous and are evolving rapidly, particularly with the introduction of mandatory electronic invoicing and the strengthening of consumer mediation rules.
Electronic Invoicing: The Game-Changing Timeline for Micro-Enterprises
Most guides dedicated to e-commerce auto-entrepreneurs stop at legal mentions and revenue declarations. They overlook a major regulatory shift: electronic invoicing will become mandatory in phases in 2026 and 2027.

Specifically, all micro-entrepreneurs subject to VAT (including those benefiting from the VAT exemption) will need to be able to receive electronic invoices starting September 1, 2026, and then issue them starting September 1, 2027. This obligation directly affects web auto-entrepreneurs who invoice for services or sell products online.
To comply, one must connect to a partner dematerialization platform (PDP) registered by the DGFiP or use the public invoicing portal. The setup requires a valid SIREN number and verification of compatibility with the Factur-X format. For those applying the VAT exemption, the mention “VAT not applicable, article 293 B of the CGI” must appear on every issued invoice, including in electronic format.

Consumer Mediation and Web Auto-Entrepreneurs
For several years, any professional selling to individuals must adhere to a consumer mediation system. This obligation applies to auto-entrepreneurs, with no exceptions related to revenue or the size of the business.
In practice, the web auto-entrepreneur must designate a referenced mediator and display their contact details on their website. The absence of this mention exposes one to an administrative fine. Field feedback varies on this point: some auto-entrepreneurs consider this obligation optional, while it is not.
The choice of mediator depends on the sector of activity. A digital service provider and a seller of physical products online do not necessarily fall under the same sectoral mediator. Checking the official list published by the Commission for the Evaluation and Control of Consumer Mediation remains the most reliable approach.
Legal Mentions and General Terms of Sale: Specific Obligations for Online Sales
The legal mentions of a website operated by an auto-entrepreneur do not stop at the name and address. For an online sales activity, the general terms of sale (CGV) must be accessible before any transaction. They govern the right of withdrawal, delivery terms, legal compliance guarantees, and return conditions.
- The 14-day right of withdrawal applies to most distance sales, except for exceptions provided by the Consumer Code (customized products, perishable goods, digital content started with express consent).
- Mandatory mentions include the seller’s identity, SIREN number, email address, the name of the website host, and the contact details of the consumer mediator.
- The privacy policy and cookie management must comply with GDPR, with a consent banner in line with CNIL recommendations.
The absence of accessible CGV on a commercial site constitutes a punishable offense, even for an auto-entrepreneur making a low volume of sales.
VAT and the VAT Exemption Regime
The auto-entrepreneur benefits by default from the VAT exemption, meaning they do not charge VAT to their clients as long as their revenue remains below the thresholds set by law. However, exceeding the thresholds leads to VAT liability, sometimes mid-year, with direct consequences on invoicing and reporting.
The thresholds differ depending on the nature of the activity (sale of goods or provision of services). A web auto-entrepreneur who combines both types of activity must monitor each threshold separately. Available data does not allow for concluding that all micro-enterprise management software correctly handles this dual monitoring, hence the importance of manually checking one’s situation each quarter.
Activity Declaration and Social Contributions of the Auto-Entrepreneur
Creating a micro-enterprise involves a declaration at the single window for business formalities. The time to obtain the SIRET number varies from a few days to several weeks depending on the period and the type of declared activity.
Social contributions are calculated as a percentage of the declared revenue, with a different rate for sales activities and service provision. The revenue declaration is done monthly or quarterly depending on the option chosen at creation. A zero revenue must still be declared, under penalty of fines.
- Contributions cover health insurance, basic retirement, CSG, and CRDS.
- The contribution to professional training (CFP) is added to social contributions, with a variable rate depending on the sector.
- The business property tax (CFE) is due from the second year of activity, unless a temporary exemption applies in certain municipalities.
The auto-entrepreneur status remains a simplified regime, but simplification does not exempt from compliance with all declarative and tax obligations. A declaration omission, even at zero, generates automatic penalties. For a web auto-entrepreneur, administrative rigor is as crucial for the sustainability of the business as the quality of the product or service offered.
