An insurer is the company or organisation that undertakes to pay covered benefits under an insurance policy. It collects premiums, evaluates applications through underwriting, handles claims, and maintains resources to meet its obligations. The insurer is the contracting party, even when an insurance agent arranges the sale.

A buyer in Nepal should confirm that a commercial insurer is authorised through the Nepal Insurance Authority and that the proposed product matches the buyer's needs. A familiar brand or persuasive salesperson does not establish the scope of protection. The issued contract and documented communications are the important records.
