Customer Case Studies

Junyang launched on Amazon Germany in April 2020. As they expanded across Europe, every new marketplace introduced compounding operational complexity — localized listings, separate FBA inventory pools, marketplace-specific advertising, currency conversion, VAT, and country-specific pricing. By the time stockouts were visible in country reports, a week of sales was already lost.

Sellerfusion as the unified operations layer. A single multi-marketplace dashboard surfacing units, revenue, ad spend, and inventory days-on-hand across every active country. Cross-region inventory visibility flagging which SKUs were over- or under-stocked in each FBA pool. Capacity-monitor reporting against FBA quotas. A repeatable expansion playbook for each new country.

Operations expanded from a single launch market to 13 marketplaces spanning Europe and the Middle East: DE, FR, GB, IT, ES, NL, BE, PL, SE, IE, AE, SA, TR. The most recent additions in the UAE and Saudi Arabia ramped to meaningful sales volume within their first quarter live — fast-ramp validation of the expansion playbook. The brand maintained on-time fulfillment and inventory accuracy across all 13 markets simultaneously.

Bencmate is one of Sellerfusion’s longest-running US-focused brands, with multiple years of cumulative sales on Amazon. After several consecutive quarters of growth, the brand experienced a meaningful year-over-year unit dip in Q1 2025 — roughly a 20% drop versus the prior-year quarter. The team needed to diagnose the cause and rebuild momentum without simply throwing more spend at PPC.

Per-SKU sales decomposition to isolate which products had lost organic ranking versus ad spend pullback. Cross-referenced advertising spend, ACOS, and conversion rate by ASIN to identify under-performing keywords and reallocate budget toward winners. Inventory-aware repricing rules to maintain competitive pricing. Same-day anomaly alerts for listing-quality issues.

Q1 2026 turned the corner. Bencmate delivered a ~16% year-over-year unit increase for the quarter, recovering close to pre-dip volume. The recovery came from surfaced insights and faster issue detection — not from incremental ad spend. Sellerfusion’s daily sales pulse continues to maintain the recovery into Q2.

Twinkle Star sells in a highly seasonal category — pool and outdoor products that ramp sharply between February and June each year. Forecasting that ramp is critical: under-stock and the brand misses the season; over-stock and they pay 4–6 months of long-term FBA storage fees on inventory that will not move until next spring. Traditional year-over-year forecasting was too coarse to detect the exact week of the demand pickup.

Sellerfusion’s daily sales view, segmented by product category and geography. Daily moving-window sales pulse comparing each day’s units to trailing 7-day and 30-day averages. Anomaly alerts triggered automatically when a SKU’s daily run-rate exceeded the prior 7-day average by more than 50%. Inventory turnover and days-of-cover dashboards to recompute restock timing as the demand signal changed.

March 2026 unit velocity came in roughly 90% higher than February. Sellerfusion alerts flagged the inflection in the first week of March, giving the operations team six weeks of lead time to coordinate restocks, adjust PPC bids upward, and reposition inventory before peak weeks. The previous baseline only caught the same signal in mid-April. No stockouts on the top SKUs by velocity throughout the season ramp.
