Does the GPSR apply to small online shops?

Yes, the GPSR makes no distinction based on business size. Whether you're a sole trader or a limited company, whether you sell 100 products a month or 10,000 — if you sell products in the EU, the GPSR applies. Exceptions exist only for very specific categories (for example, used parts under certain conditions), but these are narrowly defined. The risk: many small shops don't realise they're affected and therefore forget the mandatory information. This later leads to unexpected warnings or regulatory enquiries. Compliance starts with your first product — not once you reach a certain size.
