PROFIT-FIRST REPRICING
Your prices optimize themselves.
Onyx calculates every Amazon fee, reprices to maximize net profit, and explains every change — so you never leave money on the table.
CAPABILITIES
What Onyx handles for you
Fee Change Detection
THE PROBLEM
Amazon changes referral fees, FBA rates, and storage costs without warning. Your margins erode silently while your prices stay the same.
WHAT ONYX DOES
Onyx monitors every fee change across your catalog, recalculates net profit per SKU in real time, and adjusts prices automatically to protect your margins.
THE OUTCOME
Price Optimization
THE PROBLEM
You're winning the Buy Box at your lowest price, but you could be selling at a higher price and still winning. Every dollar left behind is pure profit lost.
WHAT ONYX DOES
Onyx tests optimal price points per SKU, factors in all Amazon fees, and finds the sweet spot where you maximize net profit while holding the Buy Box.
THE OUTCOME
Competitor Monitoring
THE PROBLEM
A competitor drops their price or goes out of stock. By the time you notice, you've either lost the Buy Box or sold hundreds of units below optimal price.
WHAT ONYX DOES
Onyx tracks competitor prices, stock levels, and Buy Box status in real time. When a competitor goes OOS or raises prices, Onyx reacts instantly.
THE OUTCOME
Margin Protection
THE PROBLEM
Race-to-the-bottom repricers keep lowering your price until you're selling at a loss. You're moving units but bleeding money on every sale.
WHAT ONYX DOES
Onyx sets hard profit floors per SKU, accounting for every fee — referral, FBA, storage, inbound. It never prices below your minimum net margin.
THE OUTCOME
DEEP DIVE
How Onyx works, step by step
Calculates actual profit before every price change
Before Onyx changes any price, it calculates your real net profit after ALL Amazon fees — referral fees, FBA fulfillment, storage, inbound placement. No other repricer goes this deep.
- Factors in every Amazon fee automatically
- Real-time COGS and margin tracking
- Reprices to maximize profit, not just win Buy Box
