môja

Müüja is the Estonian term for a person or entity that sells goods or services to customers. It can refer to a shop owner, a street trader, a market vendor, or an online seller. In everyday use, müüja denotes the party in a sale who provides the item or service in exchange for payment. The concept is central to commercial transactions and is contrasted with ostja, the buyer.

Etymology and usage notes: the word Müüja is formed from the verb müüma (to sell) with the agent suffix -ja, creating an agent noun. It is a generic label applicable to individuals, companies, or other legal entities engaged in selling. In legal and contractual language, müüja is often paired with ostja to describe the contracting parties in a sale of goods or services.

In law and consumer protection: the müüja bears responsibilities related to the sale, including delivering goods as described, and honoring applicable warranties or guarantees. When a consumer buys from a trader (a müüja), Estonian consumer protection rules typically apply, outlining information duties, right of withdrawal where allowed, and remedies for defective goods. The precise rights and remedies depend on the nature of the seller (individual entrepreneur, legal entity) and the type of transaction (consumer contract, business-to-business sale).

Contexts and forms: müüja can be a physical store proprietor, an online marketplace seller, a stallholder at a market, or a freelance service provider. The term is widely used across retail, e-commerce, and service sectors in Estonia.
