Inventory Solutions

For retailers, wholesalers & manufacturers

The Inventory Agent — an autonomous system built on 100 jewelry-specific rules. It doesn't hand you another dashboard. It tells you what to buy, what to move, and what's quietly killing your cash.

  • Dead stock detection and exit sequencing
  • Inventory turns & GMROI by category
  • Demand forecasting with seasonality
  • Memo and consignment tracking
  • Metal loss and shrinkage monitoring
  • Open-to-buy and reorder guidance

The Track Record

We Don't Consult on Jewelry.
We Sell It.

Through ADVjewel, our own Amazon jewelry division, we operate a live catalog every day. Every method we sell is tested on our own inventory first — which is why our recommendations come with numbers behind them instead of theories.

The Founder

Built by Someone
Who's Been in Your Shoes.

I started in jewelry e-commerce fifteen years ago, when selling online meant a blurry photo and a prayer. Since then I've scaled brands from zero to millions, navigated every Amazon policy change, built visual studios from scratch, and fought counterfeiters across six marketplaces.

When AI started changing everything, I didn't panic — I went all in. AMZgemz is the result: fifteen years of jewelry expertise, half a million listings of proprietary data, and the AI systems to act on both.
