Why WhatsApp suits referrals
People trust messages from friends more than ads. A referral that lands in a chat arrives with social proof attached, which lifts invite conversion.
How it works in India
Design the reward
A reward of 100 to 150 rupees on a 500 rupee order costs 20 to 30 percent of the first sale. Make sure gross margin on that order still covers it.
Measure the loop
Give each customer a code. Count invites and first purchases per code, multiply invite count by conversion, and review K-factor every month.
