NO Complexity · NO Time wasted

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 — shows honest, VAT-correct margins, and runs every rule in dry-run before anything goes live.

No black box · Dry-run first · Your floor is never paywalled

The engine

Real inputs in, protected prices out

Deterministic and explained — the same rules every pass, every decision with its reason.

Costs, VAT & fees

Your product cost, shipping and VAT, plus Amazon fees calibrated from your own listings.

Buy Box truth

Authoritative competitive data from Amazon's API — not the seller's logged-in view.

Your rules & floor

Strategy, min/max limits and the Protected Floor computed per SKU.

Win the Buy Box

Deterministic undercut to the current Buy Box price — never chasing upward.

Protected margin

No strategy setting can ever place a price below your floor.

Auto-priced 24/7

Reprices when market data changes, plus scheduled passes as a safety net.

Features

Built to be trusted with real prices

A repricer moves your prices with real money behind them. Every feature answers to that.

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. Re-checked at submit time; no strategy setting can bypass it. Lose the Buy Box, never margin.
Honest margin
VAT-correct, the way your accountant would compute it: 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: the engine logs every decision it would make — proposed price, floor and reason — without changing anything. Going live is an explicit per-rule choice, and a kill switch stops everything at once.
Auto-orchestration
Connect Amazon once — catalog, offers, orders and fees sync on their own, and repricing re-runs automatically whenever market data changes, with scheduled passes as a safety net. You watch progress, not spreadsheets.
Buy Box truth
When ownership signals are ambiguous, the engine relies on Amazon's authoritative competitive summary — not the seller's logged-in view. Decisions are made on what buyers actually see.
Multi-country
amazon.de, amazon.fr and amazon.it are verified today. Products, rules and profit are scoped per marketplace — further EU marketplaces follow per partner.

How it works

From first connection to live repricing

At your pace — nothing changes until you say so.

  1. Connect Amazon

    Authorize through Amazon's official Selling Partner API (OAuth). Your tokens are stored AES-256 encrypted — no password sharing, disconnect any time.

  2. Everything syncs itself

    Catalog, offers, orders and fees sync automatically and stay current on a schedule. No spreadsheets, no manual refresh.

  3. Set your floor & rules

    Enter or import your costs — the Protected Floor is computed per SKU from them. Attach products to a rule, or start with the safe defaults.

  4. Turn on repricing

    Dry-run first: review every decision the engine would make, with its reason. Then go live per rule — every change stays explained and audited.
