Shopify Walmart Integration

Yes. Nventory tracks WFS inventory levels in real time and includes WFS stock in your total available inventory calculations across Shopify and Walmart.

Orders routed through WFS automatically qualify. For self-fulfilled orders, Nventory helps you identify products eligible for 2-day delivery based on your warehouse locations and carrier options.

Walmart requires structured attributes like shelf descriptions, key features in bullet format, and specific product identifiers (UPC/GTIN). Nventory converts your Shopify data into Walmart's required format automatically.

Yes. You need an approved Walmart Marketplace seller account before setting up the integration. Nventory connects to your existing approved account via Walmart's API.

Nventory pushes inventory updates to Walmart within minutes of a stock change on Shopify. This is especially important because Walmart penalizes sellers for cancellations caused by overselling, and frequent sync cycles keep your Walmart listing quantities accurate.

Nventory maintains a unified inventory pool across Shopify and Walmart, deducting sold quantities in near real-time from both channels. You can also set channel-specific safety stock buffers so that Walmart's available quantity is always slightly below your true stock level to account for Walmart's stricter overselling penalties.

Start by verifying the sync delay between Shopify and Walmart — inventory updates typically propagate within a few minutes, so recent sales may not yet be reflected. Next, review your buffer stock settings in Nventory, as overly aggressive safety stock rules can cause Walmart to show lower quantities than expected. Finally, if you use Shopify's multi-location inventory, confirm that all relevant locations are included in the sync — excluded locations will cause Walmart counts to understate your actual available stock.
