Success Stories
Real results from deploying SellerVault on our own Amazon FBA operations. These case studies demonstrate the capabilities we bring to every client.
Identifying $180K+ in FBA Discrepancies
Our own Amazon FBA operation — 30K+ SKUs
Challenge
After years of selling at scale, we suspected Amazon owed us for lost and damaged inventory, fee overcharges, and missing customer returns — but manually auditing 30,000+ SKUs across months of transaction history was impossible.
Solution
We built and ran our 10-algorithm discrepancy detection engine against our full transaction history. The system identified inbound shortages, warehouse losses, 60-day return violations, and weight/dimension fee overcharges.
Results
- Detected $180K+ in reimbursement-eligible discrepancies
- Identified fee overcharges on 2,300+ products due to incorrect dimensions
- Found 890+ customer returns that exceeded the 60-day return window
- Recovery process ongoing — claims filed through Seller Central manually
Eliminating Stockouts with Demand Forecasting
Our own Amazon FBA operation — seasonal and evergreen products
Challenge
Managing restock timing for 30,000+ SKUs with varying velocity patterns and seasonal demand was causing regular stockouts on our best sellers, costing us Buy Box share and revenue.
Solution
Our restock engine uses velocity calculations, Monte Carlo simulations, and ABC-XYZ classification to generate prioritized restock recommendations with urgency scores.
Results
- Improved in-stock rate from 91% to 99.2%
- Reduced stockout-related revenue loss by an estimated 60%
- Restock recommendations now generate automatically with urgency scoring
- Ship Now indicators catch time-sensitive restock needs before it's too late
Consolidating 5 Tools Into One Platform
Our own operations team — daily workflow
Challenge
We were paying for and switching between 5 different tools: an inventory tracker, a repricer, a reimbursement service, a product scanner, and a separate analytics platform. Data didn't sync, workflows were fragmented, and CSV exports were a daily ritual.
Solution
SellerVault was built specifically to eliminate this tool sprawl. Every feature shares the same data layer, so repricing decisions are informed by restock status, profitability includes advertising spend, and reimbursement recovery is tied to actual product-level financials.
Results
- Eliminated 5 separate SaaS subscriptions
- Saved $400+/month in combined tool costs
- Reduced daily operational workflow time by approximately 2 hours
- All data in one place — no more CSV export/import between tools
