Infrastructure that
just works.
Onyx integrates into your Seller Central account and handles repricing automatically. No disruption. No complexity. Just reliable infrastructure.
The Process
Four steps to higher margins
Connect Your Account
Link Seller Central through Amazon's official SP-API. Onyx connects securely to your account without replacing anything. Setup takes minutes, not months. Your existing workflow stays the same -- Onyx just works alongside it.
Set Your Strategy
Pick a preset or describe your own in plain English. Onyx understands your margin targets, competitor positioning, and pricing boundaries. It adapts to the way you already think about your catalog.
Onyx Optimizes
AI monitors competitors, calculates fees, and adjusts prices 24/7. Buy Box positioning is optimized automatically. Edge cases get flagged for your review. Onyx handles the repetitive repricing work so you can focus on sourcing and growth.
Watch Profits Grow
Every change explained, every fee calculated. Performance is tracked across your entire catalog. Margin improvements are visible in real time with full transparency into every repricing decision Onyx makes.
What Onyx handles reliably
- Monitor competitor prices around the clock
- Calculate Amazon fees and true net margins
- Adjust prices to win and hold the Buy Box
- Flag unusual market conditions for your review

Core Philosophy
Reliability beats novelty
Onyx is designed to do fewer things well rather than many things poorly. Every repricing rule is scoped, tested, and monitored. We do not chase features. We chase consistency. The system gets better over time because improvement is built into the process -- not bolted on after the fact.
Same every time
Consistent repricing regardless of volume, time of day, or market volatility.
Defined scope
Clear boundaries on pricing floors, margin targets, and what gets flagged. No ambiguity.
Deliberate improvement
Changes are intentional, reviewed, and measured. Nothing is left to chance.
You stay in control
Every floor price, every margin target, every rule is set by you. Onyx executes within those lines.
Removes repetitive load
The price checks you have done a thousand times. The fee calculations that follow the same pattern. Onyx takes those off your plate.
Guardrails built in
When something falls outside scope, Onyx does not improvise. It flags the ASIN for your review with full context.
Competitor changes price
A rival adjusts their listing at any hour of the day.
Onyx responds
Calculates the optimal price using your strategy, fees, and margin rules.
Margin protected
Price updated, Buy Box targeted, and profit margin preserved. Done.
24/7 operation. This process runs around the clock. No gaps when you sleep, no missed price changes on weekends, no coverage holes during peak season.
Onyx fits sellers that value consistency.
Every missed repricing opportunity and delayed price adjustment is lost margin. Onyx makes sure those gaps stop happening -- quietly, reliably, every single day.
