Do I have to comply if I only sell via Bol or Amazon?

Selling via bol or Amazon does not automatically make the law applicable

Yes, in most cases the accessibility law also applies to those who sell only via bol, Amazon or another marketplace platform — although it works slightly differently than with your own webshop. The European Accessibility Act is directed at the party offering the service to the consumer, and when selling via a marketplace platform, this is usually the seller of the product, not just the platform itself. The platform has its own obligations in addition, but this does not exempt the seller from checking whether their own situation falls under the directive.

What this amounts to in practice: your own sales environment on the platform — the product page, the checkout process, customer contact — counts as part of the service to the consumer. If a shop has no website of its own and sells exclusively via such a marketplace platform, the main question is whether it qualifies as a micro-enterprise; that exemption is precisely the point to check via Am I exempt from the accessibility law as a small business?. If that is not the case, it is advisable to look at your own situation more broadly, for example via Does the accessibility law apply to my webshop?, because the size of your own business and the nature of the service provided together determine whether, and how, the law applies.

Where this comes from: the definition of services to consumers

Directive (EU) 2019/882 defines accessibility requirements in terms of services offered to consumers, without requiring the provider to have their own website; selling via a marketplace platform generally falls under this, because the entrepreneur is in fact the party delivering the e-commerce service to the consumer. In the Netherlands, ACM supervises the accessibility of websites and apps and focuses on the party providing the service, meaning that a seller operating only via a platform cannot automatically count themselves out. What exactly counts as "own service provision" within a marketplace platform environment is not always clearly defined, and the scope check provides an initial direction for this.
