An e-commerce site that generates traffic but doesn’t convert, a sales page written by AI without legal mention, a payment funnel that triggers disputes: these concrete situations are crippling online businesses every week. Growing your activity on the web is not just about choosing a niche and launching a marketing campaign. Regulatory, technical, and commercial constraints have tightened, and ignoring them costs more than anticipating them.
Electronic invoicing and AI Act: two deadlines that change the management of an online business
Most guides on online business discuss marketing strategy without mentioning recent administrative obligations. This is a mistake, because these obligations directly alter the tools and daily processes.
Since August 2, 2026, the AI Act imposes a transparency obligation on chatbots and content generated by artificial intelligence. If you use a conversational assistant on your site or if your product descriptions are automatically generated, the user must be informed that they are interacting with a machine. Synthetic content must be flagged.
For those selling services online, writing product descriptions via AI, or deploying a customer support chatbot, this is not a detail. Non-compliance with these rules exposes you to sanctions, and especially to a loss of trust from buyers.
Another deadline to watch: the obligation to receive electronic invoices will come into effect on September 1, 2026, for the relevant French companies. Additional resources can be found to structure this transition, particularly to learn more about entrevue-web.fr, which addresses these operational topics. The issuance will then gradually generalize according to the size of the company. A sole proprietor selling online courses or consulting is concerned just as much as an SME.
Online customer acquisition: betting on a proprietary channel before social networks
There is a common reflex among web entrepreneurs: to concentrate all the budget on social advertising or paid search. The problem is that you rent an audience without ever owning it. A majority of B2B marketers pay to access audiences they do not control.
Building an email list remains the most profitable acquisition lever for an online business. Unlike a social network algorithm, the email list does not depend on any third-party platform. You decide the timing, format, and message.
In practice, this involves a few simple actions:
- Offering high-value content (practical guide, checklist, mini-training) in exchange for an email address, directly on the website
- Segmenting the list from the start according to the profile or expressed need, to send targeted sequences rather than generic newsletters
- Automating follow-ups post-registration with an email marketing tool suitable for small structures, without heavy investment
Returns vary by sector, but in niche markets (coaching, crafts, business services), email marketing regularly outperforms social campaigns in conversion rates.
Short video and customer testimonials: the content that sells
Publishing SEO-optimized blog articles is no longer enough to convince a prospect. The online purchasing journey increasingly involves short video, particularly through video testimonials.
Video reviews reduce purchase friction much better than traditional text reviews. A filmed customer explaining their experience with a product or service creates a social proof effect that is hard to replicate otherwise. Several recent analyses confirm that consumers make their purchasing decisions after watching short videos.
Concrete format to start without a video budget
No need for a studio. A smartphone, good natural lighting, and a satisfied customer are enough. You film a spontaneous response to three questions: what was the problem, what solution was chosen, what result was obtained.
These videos are shared on the sales page (not just on social media). Placing a video testimonial next to the purchase button changes the conversion rate of a product page. Social commerce is advancing rapidly, and shoppable video formats (where you can buy directly from the video) are starting to become mainstream.
Securing the payment funnel to avoid disputes
An online business that collects payments without anticipating disputes exposes itself to cash flow problems. Payment disputes (chargebacks) represent an increasing cost for merchants, and so-called “friendly” fraud (a customer disputes a legitimate purchase) is skyrocketing.
The European PSD3/PSR reforms will strengthen identity verification of the beneficiary and modify the merchant’s liability in case of dispute. Anticipating these changes at checkout protects revenues and limits losses.
Here are a few concrete measures to implement:
- Using a payment provider that integrates enhanced identity verification and automation of Visa/Mastercard disputes
- Clearly displaying refund conditions and the business name that will appear on the customer’s bank statement
- Keeping proof of delivery or access to the service (login logs, confirmation emails) to contest abusive chargebacks
This payment aspect is rarely addressed in marketing guides, but it directly conditions the profitability of an online activity.
Developing a profitable online business relies as much on regulatory compliance and payment security as on marketing strategy. Entrepreneurs who integrate these constraints from the outset avoid costly corrections a few months later. The next point of vigilance: ensure that every AI tool used on the site complies with the transparency obligations that came into effect this summer.
