Three things Walmart sellers told us
Walmart drives volume.
The feed lag is what costs you.
01
"Our Walmart feed runs nightly. By morning the count is wrong and we are cancelling orders."
Inventory is event-driven, not a nightly feed. A sale anywhere decrements Walmart within seconds — cancellations stay near zero.
Secondsnot the next feed
02
"A repricer dropped us below MAP and the item got suppressed for a week."
Price changes are MAP-aware. A push that would breach a floor is held and flagged before it ever reaches Walmart.
MAP-awareprice guard
03
"WFS and seller-fulfilled stock live in two places and never reconcile."
WFS inventory is read back from the WFS API while seller-fulfilled stock is published from your warehouses — one picture.

The item flow
Every Walmart field, in one form.
Validated before the feed.
Variant groups, attributes, shelf categories and offer data — managed in the master catalogue and pushed through the Marketplace item feed.

Inventory sync
A stock count Walmart won't cancel orders over.
Inventory reaches Walmart through the Marketplace API in seconds — not a nightly feed. WFS levels are read back so seller-fulfilled and WFS stock stay one picture.
WFS + seller-fulfilled
WFS quantities are read back continuously while seller-fulfilled stock is published from your warehouses.
MAP-aware pricing
A price push that would drop a SKU below its MAP floor is held and flagged before it reaches Walmart.
Throttle-aware feeds
Updates batched into Walmart feed envelopes and paced to the API quota — never queues for hours.
Reservations during pick
Seller-fulfilled stock decrements at allocation, not at label — no double-sells while orders sit unpicked.

Asked before every Walmart seller switches
Six questions.
Honest answers.
Yes. WFS inventory is read back from the WFS API while seller-fulfilled stock is published from your warehouses — both shown as one picture.
Price pushes are MAP-aware. A change that would drop a SKU below its minimum advertised price is held and flagged before it ever reaches Walmart.
Yes. We use the Marketplace API directly rather than waiting for a scheduled feed, so a stock change reaches Walmart in seconds — not the next overnight run.
Yes. Each account connects separately with its own orders and metrics, but the canonical catalogue is shared.
Yes. Walmart variant groups map to our variant SKUs, so stock and price stay correct across every size and colour.
No. The first sync matches your live Walmart items to the catalogue by SKU, then GTIN. Matched items stay the same item — we just attach our record.
