Reprice to win the Buy Box. Never below your real margin.

NOXENI Price Engine is a profit-first repricer for Amazon EU sellers. It computes a Protected Floor from your true costs — product, shipping, VAT, and Amazon fees calibrated from your account's real data — and no strategy can ever price below it.

Free plan available · dry-run by default · live repricing only after you enable it

Where a price is allowed to go
The Protected Floor is a hard bound on every SKU, in every plan.
Overpriced — the Buy Box drifts away
Winning zone
Competitive and above your floor — the engine only works here.
Below your real margin — never
No strategy setting or price war can place a price here.

Built on three principles

A repricer moves your prices with real money behind them. It has to earn trust first.

Protected Floor
A hard lower bound per SKU, computed from your product cost, shipping, VAT and Amazon fees — calibrated against the fees observed on your own listings, not category estimates. Every proposed price is re-checked against the floor at submit time.
Honest margin
Margin is computed the way your accountant would: VAT handled correctly, product cost, outbound shipping and real Amazon fees included. When an input is missing, the engine holds and tells you what is missing — it never guesses.
Dry-run first
Every rule starts in dry-run: you see exactly what the engine would change, per SKU, with the reason. Live repricing starts only after you explicitly enable it — and a kill switch stops everything at once.

How it works

From first connection to live repricing — at your pace, with nothing changed until you say so.

1
Connect Amazon
Authorize through Amazon's official Selling Partner API. Your catalog, offers and orders sync automatically — no spreadsheets, no password sharing.
2
Add your costs
Enter or import product costs and shipping. The engine calibrates Amazon fees from your own listings and computes a Protected Floor for every SKU.
3
Review in dry-run
The engine evaluates your catalog and logs every decision it would make — proposed price, floor, and the reason — without changing anything.
4
Go live, guarded
Enable repricing per rule and marketplace when you are ready. Guardrails stay on, every change is audited, and a kill switch stops everything at once.

Pricing

Three plans, one rule: safety is never paywalled. Protected Floor, min/max guardrails and dry-run are included in every plan.

Questions, answered plainly

How do I get access?

We are in early access and onboard a small group of sellers personally: connect, calibrate fees, verify your floor together, then go live. Email [email protected] or use "Request access" and tell us about your catalog.

Which marketplaces are supported?

Amazon's EU region. Catalog, offers, orders and profit tracking work across EU marketplaces. Live repricing is enabled per marketplace once fee calibration is verified for your catalog — amazon.de, amazon.fr and amazon.it are verified today, further EU marketplaces follow per partner.

Can it wreck my prices?

No. The Protected Floor is computed from your real costs and re-checked at submit time, alongside your own min/max limits. Every rule starts in dry-run, going live is an explicit per-rule decision, a kill switch stops everything instantly, and every change is logged with its reason.

What data do you access?

Only what repricing needs, via Amazon's official SP-API: your catalog, offer and Buy Box data, and order totals for profit calculation. We do not request or store your buyers' personal data. You can disconnect at any time — details are in the privacy policy.

What does it cost?

The Free plan is free. Pro pricing is agreed individually and up front during early access — no card, no surprise billing. Public self-serve pricing comes with the public launch.

See what it would do with your catalog — before it does anything.

Connect your account, load your costs, and review the engine's decisions in dry-run. Going live is your call, per rule — never a default.
