Social commerce is selling in which a social platform plays a role in product discovery, contact or ordering. The payment does not have to take place in Instagram or Facebook for that. A Belgian business can show a product and guide the customer to its own ordering route. Do not make a working route dependent on a Shop or product tag feature that your account does not yet have.
Meta features depend on market, account and approval. Therefore check the current supported markets and commerce terms. This guide does not promise general availability of Shops, product tags or built-in checkout for every Belgian account.
