A referral agreement should cover several aspects, such as the scope and duration of the agreement, the referral process and criteria, compensation and payment terms, performance and quality standards, as well as confidentiality and non-compete clauses. The agreement should specify which products or services are eligible for referrals, how long the agreement lasts, and how it can be terminated or renewed. It should also explain how the referrer should identify, contact, and qualify potential customers, and how they should submit the referrals to you. Furthermore, it should determine how much and how often the referrer will be paid for each successful referral, such as a fixed fee or a percentage of the sale. Additionally, set expectations and goals for the referral program and establish how you will track and report the results. Finally, protect your intellectual property by requiring the referrer to keep them confidential and not to disclose them to third parties.
