1. What is FBA and What is MCF?
Fulfillment by Amazon (FBA) is Amazon’s fulfillment program, where Amazon stores, packs, and ships products for sellers. This allows sellers to provide Prime-level speed and reliability without handling logistics themselves.
Multi-Channel Fulfillment (MCF) in 3Dsellers lets you extend that same capability beyond Amazon: you can use your FBA inventory to fulfill orders placed on other channels like eBay, Shopify, or Walmart. When an order comes in from one of those channels, MCF automatically routes it to Amazon FBA for fulfillment.
2. How 3Dsellers Supports FBA Products
When you connect your Amazon account in 3Dsellers:
An FBA warehouse is automatically created in your account.
3Dsellers listens to Amazon FBA inventory updates in real time.
If a product has FBA stock, that stock is automatically assigned to the FBA warehouse in 3Dsellers.
⚠️ Important: FBA inventory cannot be manually edited in 3Dsellers — it always syncs directly from Amazon.
This ensures your product catalog always reflects accurate inventory levels from Amazon.
3. FBA Automation: Settings and Behavior
Turning on Automation
Go to Products Catalog > Integrations > Channel Settings.
Open your Amazon integration settings.
Toggle Enable FBA order fulfillment automation.
Choose your shipping method (e.g., Standard Shipping).
(Optional) Configure:
Block Amazon Logistics carrier if you want shipments routed through other carriers.
Use unbranded packaging for a neutral delivery experience.
Decide whether to:
Fulfill FBA orders for all channels, or
Select specific channels where automation should apply.
What Happens When Automation is On
Orders from your selected channels are automatically routed to Amazon FBA for fulfillment.
Tracking updates flow back into 3Dsellers and sync with the original order.
Inventory from Amazon FBA is made available across your connected channels.
What Happens When Automation is Off or Excluded
If automation is disabled (globally or per channel), FBA inventory will not be sent to that channel.
Example:
You have 50 FBA units in Amazon.
If automation is off for Shopify, your Shopify listing will show 0 units to prevent overselling.
This gives you full control over where your FBA inventory is offered.
Conclusion: Why This Matters
With 3Dsellers’ Amazon MCF, you can:
Automatically sync and route orders from multiple channels to Amazon FBA.
Keep inventory accurate across platforms without manual updates.
Choose exactly where your FBA inventory is offered.
Deliver a consistent customer experience with Prime-speed fulfillment, even off Amazon.
In short, Amazon MCF through 3Dsellers helps sellers expand sales channels, save time, and leverage the reliability of FBA everywhere they sell.
