Case Study 02
U.S. Sports & Outdoors Recovery Brand
$572,785 in incremental revenue over 6 months. 72.7% YoY growth.
Snapshot
- Category: Sports & Outdoors (resistance bands and recovery equipment), U.S. marketplace
- Engagement: October 2025 to present, 6+ months active
- Service tier: Full Account Management plus inventory operations
Starting state
Revenue had plateaued around $145K per month over the prior 18 months. Chronic stockouts were suppressing organic rank and breaking ad performance. The founder had stable demand but couldn’t convert it because product wasn’t reliably available. Goal was YoY growth with stable inventory.
What we did
- Diagnosed inventory inconsistency as the binding constraint, not advertising. Built forecasting models tied to sales velocity, seasonal demand, and promo uplift
- Implemented a structured reorder cadence with lead-time buffers, coordinated with the supply chain team and FBA processing windows
- Maintained near-zero stockout periods across the full 6-month engagement
- Rebuilt PPC architecture across Exact, Phrase, Broad, Auto, ASIN, and category targeting
- Deployed Lightning Deals, 7-Day Deals, Subscribe & Save, and strikethrough pricing on the promotional layer
- Rewrote titles, bullets, A+ content and built a multi-page Brand Store

Same-month year-over-year
Comparing each month directly to the prior year isolates management impact from seasonal noise.

The strongest gains came in months that had historically been the brand’s weakest. January (+106%) and February (+97%) typically lag the calendar; with inventory stable for the first time in 18 months, seasonal demand could finally be captured.
The inventory turnaround
Stockouts at this brand were chronic before onboarding. Suppressed organic rank, broken PPC pacing, and lost momentum every time a top SKU went out of stock. The founder had stable demand but couldn’t convert it because product wasn’t reliably available.
We diagnosed inventory as the binding constraint, not advertising. Built a forecasting model with sales velocity, seasonal demand spikes, and promotional uplift as inputs. Implemented a structured reorder cadence with lead-time buffers, coordinated with the supply chain team and FBA processing windows.
Result: near-zero stockout periods across the full 6-month engagement, a meaningful operational shift versus the prior 18 months. With inventory stable, every dollar of PPC spend compounded properly. Organic rank recovered and held. Promotional spikes (Lightning Deals, Best Deals) actually drove sustained velocity instead of running into stockouts during the demand surge.
Strategy in detail
Inventory operations
Forecasting model tied to sales velocity, seasonal demand patterns, and promo uplift. Reorder cadence with lead-time buffers. Coordination with supply chain to align inbound shipments with FBA processing windows. Stranded and suppressed inventory managed weekly to keep all listings active.
PPC architecture
Rebuilt campaign structure across Exact, Phrase, Broad, Auto, ASIN, and category targeting. Bid optimization with dayparting for peak conversion windows. Weekly negative keyword harvesting and search term mining.
Promotional strategy
Lightning Deals and 7-Day Deals scheduled within each month to create velocity spikes that signaled demand to the algorithm. November’s record month was anchored by Best Deal scheduling. Subscribe & Save program activated to drive repeat purchases. Strikethrough pricing established through systematic reference-price management.
Listing and brand store
Titles, bullets, A+ Content rewritten against Search Query Performance data. Multi-page Brand Store built to improve cross-selling and brand visibility. Image stack refreshed with hero plus lifestyle plus infographic across the catalog.
What’s next
Active engagement. Q3 priorities: international expansion (UK and CA), Subscribe & Save retention rate optimization, and Q4 prep around peak Black Friday and Cyber Monday windows.
“They fixed our inventory problem first. Once we stopped going out of stock, the growth followed. We had our strongest January and February in the brand’s history.”
