People also ask

Q.Is a referral invite Marketing or Utility?

The invite send IS customer-initiated (they tap Share) — fully free. Only the inviter's reward confirmation is a Utility template.

Q.How do I structure the reward?

Double-sided works best: ₹100 / $10 / €10 to the inviter on first qualifying purchase, plus the same value to the new customer's first order.

Q.How do I prevent self-referral fraud?

LandinChat blocks same-device, same-IP, and same-payment-method referrals. AI flags suspicious patterns (rapid sign-ups, fake numbers).

Q.What viral coefficient should I expect?

Healthy programs hit K=0.3–0.7 (each customer brings 0.3–0.7 new customers). K=1.0+ is true viral growth.

Q.Can I gate rewards on minimum order value?

Yes — set a minimum AOV threshold for reward unlock, plus optional product-category gates.

Q.How do I track referral attribution?

Unique referral code per inviter + Shopify discount-tag attribution. Full dashboard with K-factor, payout tracking and top-referrer leaderboard.

Overview

Why WhatsApp referrals beat email and link-share

Email referral programs hover at K=0.05–0.1 — virtually no viral lift. WhatsApp share is one tap, lands in a personal thread, and converts at 3–5x because it's a real friend-to-friend recommendation.

Because the share itself is customer-initiated, it's free — you only pay for the inviter's reward confirmation (Utility template) and the new customer's welcome (Marketing template).

LandinChat blocks self-referral fraud (same-device/IP/payment-method) and runs an AI ranker on sign-up patterns. Healthy programs hit K=0.3–0.7 and cut CAC by 60–80%.
