1. What is WFS and What is MCS?
Walmart Fulfillment Services (WFS) is Walmart’s fulfillment program, where Walmart stores, packs, and ships products for sellers. Similar to Amazon FBA, WFS helps sellers provide fast shipping and reliable service without handling logistics themselves.
Multi-Channel Solution (MCS) in 3Dsellers takes this a step further: it lets you use your WFS inventory not just on Walmart, but also on other channels like eBay, Shopify, or Etsy. When an order comes in from one of these channels, MCS automatically routes it to Walmart to be fulfilled via WFS.
2. How 3Dsellers Supports WFS Products
When you connect your Walmart account in 3Dsellers:
A WFS warehouse is automatically created in your account.
3Dsellers listens to Walmart inventory updates in real time.
If a product has WFS stock, that stock is automatically assigned to the WFS warehouse in 3Dsellers.
⚠️ Important: WFS inventory cannot be manually edited in 3Dsellers — it is always synced directly from Walmart.
This ensures your product catalog always reflects accurate inventory levels from Walmart.

3. WFS Automation: Settings and Behavior
Turning on Automation
Go to Products Catalog > Integrations > Channel Settings.
Open your Walmart integration settings.
Toggle Enable WFS order fulfillment automation.
Choose your shipping method (e.g., Standard Shipping).
Decide whether to:
Fulfill WFS orders for all channels, or
Select specific channels where automation should apply.
Example – Walmart Integration Settings:
What Happens When Automation is On
When enabled, orders from your selected channels are automatically routed to Walmart WFS.
Tracking updates flow back into 3Dsellers and sync with the original order.
Inventory from Walmart WFS is used across your connected channels.
What Happens When Automation is Off or Excluded
If automation is disabled (globally or per channel), WFS inventory will not be sent to that channel.
Example:
You have 10 WFS units in Walmart.
If automation is off for eBay, your eBay listing will show 0 units to prevent overselling.
This gives you precise control over where WFS inventory is offered.
Conclusion: Why This Matters
With 3Dsellers’ Walmart MCS, you can:
Automatically sync and route orders from multiple channels to Walmart WFS.
Keep inventory accurate across platforms without manual updates.
Decide exactly where your WFS inventory is offered.
This means less time managing logistics and more time growing your business.
