Playbook: Hardening a B2B Referral Program Against Self-Dealing

Playbook: Hardening a B2B Referral Program Against Self-Dealing

Enterprise referral programs leak through self-referral, collusion, and incentive-chasing. A controls checklist, layered from cheap to costly:

— Step 1. Block the obvious self-deal. Match referrer and referred-account domains and employee records; flag same-company referrals for review.
— Step 2. Gate the payout on a real outcome, not a form submission. Pay on closed-won or a verified qualified stage, which removes most speculative abuse.
— Step 3. Watch velocity and clustering. A sudden spike of referrals from one source, or many referrals sharing infrastructure signals, warrants manual review.
— Step 4. Require a verifiable relationship claim. The referrer should attest how they know the prospect; false attestations create a clear policy basis for clawback.
— Step 5. Sample and audit. Even a small random audit changes behavior more than the audit catches.

Trade-off: aggressive controls cut fraud but add friction that suppresses legitimate referrals, which are already a high-trust, high-value channel. Over-policing can cost more in lost good referrals than it saves.

Base-rate caution: in genuinely high-trust B2B networks, fraud rates are often low, so heavy-handed controls may be solving a small problem at a large cost — size the leak before building the dam.

Implications: tie controls to payout magnitude. Reserve manual scrutiny for high-value or anomalous referrals, not the median one.
