Final answer:
Agent Sam should pay Agent Layla the referral fee through formal means like direct bank transfer, check, or approved digital payment systems after receiving an invoice that outlines the fee to be paid. Proper documentation is necessary for legal and tax reasons.
Step-by-step explanation:
When Agent Sam owes Agent Layla a referral fee, the process of transferring the fee must adhere to company policies and legal regulations within their field. Typically, the payment of a referral fee would occur in a formalized manner, usually involving an invoice from Layla to Sam, which details the agreed-upon amount. Once the invoice is received, Sam would typically remit payment through company-approved channels, such as a direct bank transfer, a check, or digital payment systems that both agents have agreed upon. It is also important to document the transaction thoroughly for tax and legal purposes and to ensure that both agents have a record of the payment.
