The Challenge
The brand had natural demand and a strong identity — but lacked the infrastructure to scale it. Inventory wasn’t forecasted, paid media was inconsistent, and core retention channels like email and SMS were underutilized. Without clear prioritization of bestsellers, high-potential revenue was getting lost in the noise.
The ZOS Solution
ZOS built a full-scale evergreen engine designed to align demand with creative, CRO, and retention. We didn’t just chase performance — we built a system around it.
Core Elements:
- Sales Data Audit: Identified top-performing SKUs by velocity, margin, and repeat rate.
- Evergreen Restock System: Ensured bestsellers never ran out mid-funnel, preserving momentum.
- Performance Creative Frameworks: Developed repeatable content strategies tailored to customer archetypes to drive cold traffic and scale efficiently.
- Offer System Consistency: Aligned product offers across paid ads, website UX, and backend flows (email/SMS).
- Retention Flow Optimization: Revamped underutilized Klaviyo flows to capture drop-off, boost returning customer rate, and extend LTV.
The Results
- 100% increase in Q2 YoY revenue
- Ad returns scaled from 2.5x–3x → 8x–12x average ROAS
- Faster sell-through of old inventory, thanks to reinvestment loop
- Higher acquisition efficiency from cold traffic, due to structured creative angles
- Increased revenue per visitor from harmonized offers across CRO, email, and SMS
Why It Worked
ZOS didn’t just help Cough Syrup scale — we engineered the infrastructure behind its growth. By building around what customers already wanted and removing internal bottlenecks across creative, offers, and retention, the brand now has a foundation that can scale consistently across any season or collection.
