Lumi for Walmart Marketplace
The repricer that treats Walmart
as first-class, not an add-on.
Most repricers were built for Amazon and bolted Walmart on later. Lumi was designed on Walmart Marketplace from day one — WFS-aware Buy Box logic, Walmart fee structures, and Walmart's competitive dynamics are the default, not a port.
Built around how Walmart actually works
WFS-aware Buy Box strategy
Walmart's Buy Box weighs fulfillment quality heavily. Lumi models WFS vs seller-shipped on every competing offer, so a WFS seller can hold the Buy Box priced above seller-shipped rivals instead of matching them down.
Walmart fee-aware floors
Referral fees by category and WFS fulfillment costs are built into breakeven math. Your floor is computed from what you actually keep — not a guess.
Fewer sellers, sharper spirals
Walmart listings often have fewer competing offers than Amazon — one aggressive repricer can drag the whole listing down fast. SpiralGuard™ is at its best here: detect, hold, and recapture on the reset.
Official Walmart API, delegated by you
Lumi connects through the Walmart Marketplace API after you authorize it from Seller Center — the platform's supported model for solution providers. Revoke anytime.
Selling on Amazon too?
Run both marketplaces from the same dashboard with the same strategies — one catalog view, one set of guardrails, per-marketplace tuning where it matters.
Founding Walmart sellers wanted
We're onboarding a limited early-access group of Walmart Marketplace sellers. Founding members get direct input on the roadmap and keep early-access pricing.
