⚡

Buy Box–aware repricing

Lumi tracks the Buy Box price and secondary offers on every listing and positions your price to win — not just to be cheapest.

🛡️

Margin guardrails

Set a floor and ceiling per SKU or per rule. Lumi never prices below your minimum margin, no matter what competitors do.

📈

Reprice up, not just down

When competition thins out, Lumi raises your price back toward your ceiling — capturing profit most repricers leave behind.

📦

Built for large catalogs

Designed from day one for sellers with thousands of SKUs. Bulk rules, CSV import/export, and catalog-wide strategies.

Alerts & insights

Know when you win or lose the Buy Box, when a competitor goes out of stock, or when a SKU hits its floor.

🔒

Official APIs only

Lumi connects through the official Walmart Marketplace and Amazon Selling Partner APIs with seller-authorized OAuth access.

How it works

  1. 1

    Connect your store

    Authorize Lumi from your Walmart Seller Center or Amazon Seller Central account using the official app authorization flow. You never share your passwords or API keys.

  2. 2

    Set your strategy

    Import your catalog, set cost and margin floors, and choose a repricing strategy per SKU, per category, or catalog-wide.

  3. 3

    Lumi takes over

    Prices adjust automatically as the market moves. You watch Buy Box share and margins from one dashboard — and stay in control with full price-change history.

Your data, handled properly

Lumi is built by Aurora PowerUp LLC to meet the marketplace platforms' data protection standards.

Seller-authorized access only

We access your account exclusively through official marketplace APIs after you explicitly authorize Lumi. You can revoke access at any time from your seller dashboard.

Encryption everywhere

All data is encrypted in transit (TLS 1.2+) and at rest (AES-256). Credentials and tokens are stored in a managed secrets vault.

Strict data isolation

Each seller's data is logically isolated. Your catalog, costs, and pricing strategies are never shared with, or visible to, any other Lumi customer.

Minimal retention

We only collect the data required to reprice your listings, and we retain it no longer than platform policies allow. See our Privacy Policy.
