One Inventory Pool. Every Channel You Sell On.
Walmart Multichannel Solutions lets you fulfill Amazon, eBay, Temu, TikTok Shop, and your own website from the same Walmart Fulfillment Services inventory. StoreAutomator is your integrated MCS solution provider. We automate orders and inventory across every channel, so one pool does all the work.













Connect every sales channel to Walmart Fulfillment
Walmart Multichannel Solutions (MCS) lets Walmart Fulfillment Services fulfill orders from any ecommerce site you sell on. StoreAutomator connects you to it, converting your catalog to Walmart-fulfilled, mapping your sales channels, and keeping inventory and orders in sync, without spreadsheets or manual order routing.

Inventory in sync
One source of truth. As WFS ships, stock updates across every channel instantly, so you stop overselling and stop reconciling by hand.
As an approved Walmart Marketplace channel partner, we keep the MCS integration up to date with the latest API requirements. The result: faster delivery, lower fulfillment costs, and less workload, with one world-class supply chain behind every channel you sell on.
Every order flows to WFS automatically
StoreAutomator is connected directly to Walmart's Multichannel Solutions API. Orders from any channel flow into WFS automatically, with no spreadsheets or manual uploads, while inventory stays synced in real time.
Automated order routing
Every order from Amazon, eBay, TikTok, and your own store is sent to WFS for fulfillment automatically through the MCS API.
Fast, unbranded shipping
Ship in as little as two days in unbranded packaging, nationwide across all 50 states and Puerto Rico.
Zero referral fees off-Walmart
Pay no Walmart referral fees on orders from your non-Walmart sales channels.
