Referrals that convert your best customers into your best channel.

Loyalty tier data sets the referral reward, so your highest-value customers get the strongest incentive to bring in the next one. Triggers fire at peak satisfaction, a second purchase, a five-star review, a tier upgrade, not on day one.

WHAT WE SHIP

Referral trigger placement

Referral prompts fire at the highest-satisfaction moments in the journey, a second purchase, a positive review, a tier upgrade, not straight after the first order when trust hasn't formed yet. Timing is sequenced against loyalty milestones so the two never compete.

Referral incentive structure

Give-get incentives, where both referrer and referee are rewarded, typically outperform gift-only for brands with strong repeat purchase rates. Reward value is calibrated against referred-customer lifetime value, not a flat acquisition cost benchmark.

Tier-multiplier rewards

Your highest loyalty tiers earn a bigger referral reward, calibrated against tier structure and referred-customer LTV rather than a fixed schedule. This lifts participation from your most credible referrers, the customers who already rate you highest.

Attribution and fraud prevention

Every referred order is tracked to its referrer, incentive type and trigger, with self-referral exclusions, velocity caps and email validation built in before rewards go out. Attribution is audited on a set cadence, so anomalies get caught before reward costs add up.

Review-driven referral seeding

Customers who leave a five-star review are invited into the referral programme with a message that references their own words, because your happiest customers convert best as referrers. This turns a satisfaction signal directly into a new acquisition channel.

Referral cost measured against blended CAC, not in isolation

Referral reward cost per acquired customer sits on the same dashboard as paid CAC, so the programme is judged against the channel it's meant to be cheaper than, not against its own budget line. When referral CAC creeps toward paid CAC, incentive value gets recalibrated before the channel stops paying for itself.
