The agent works on a commission basis, i.e. he acts in the interests of his client and usually receives a fee, a commission after successful brokerage or after the transaction has been concluded. The services vary greatly from broker to broker and the small print in the contracts should also be studied carefully. The same applies to verbal contracts, i.e. the Swiss Code of Obligations regulates the most important rights and obligations of the parties (see OR Article 412ff). In any case, take your time when choosing a broker, as a small mistake can have serious financial consequences.
