- Items must meet the  product requirements f or WFS. 
- Multi-box and big and bulky  items are currently not eligible.

MCS in Seller CenterÂ
If you are already using WFS, you are likely familiar with Seller Center. It’s where you’ll complete most tasks related to Multichannel fulfillment. This is your home base to add or update sales channels, manage orders and returns, estimate fulfillment fees and more. If you’re not a WFS seller yet, find out more about getting set up here.Â

Step 1: Add sales channelsÂ
 Once you have logged in to Seller Center, you will need to create your sales channels before placing customer orders. Here’s how:Â
Â
- Go to the  Multichannel settings  page and select Add channel.
- From the dropdown, choose an existing third-party channel or create your own. (Don't forget to give your sales channels a unique name, so you can tell them apart.)
- Choose a ship-from address. This is where we’ll send customer returns and undeliverable shipments.
- Choose your shipment carrier. Some channels prefer specific carriers, and we'll highlight our recommendation based on the channel. You are welcome to switch to any package you like.Â
-Package A includes all carriers: FedEx, UPS, USPS, LaserShip, and OnTrac.Â
-Package B includes UPS, LaserShip, and OnTrac. It will exclude Fedex and USPS.Â
-Package C includes Fedex, UPS, and USPS. It will exclude LaserShip and OnTrac.Â
NOTE: Restricting Carriers will limit coverage area and may affect shipping SLAs. - Add the sales channel. Create as many channels as you need.
We generate a unique sales channel ID to tell each channel apart during fulfillment. You’ll use this sales channel ID when you create customer orders. You can always find sales channel ID on the  Sales channels  page.Â

Â
- From the  Multichannel Orders  page select  Manage fulfillment, then either Single order or Multiple orders  from the dropdown.
- For a Single order, add the sales channel ID, customer information, shipping speed and item details. Your carrier preference package, based on the sales channel, will be displayed here. Review the order, then submit.
- For Multiple orders, first download the template.
- Fill in the template with order channel IDs. You can find these in the  Multichannel Settings  page under the Sales channel ID column. Add customer information and item details, choose the ship speed in the Shipping Method column. Review, then upload the template and submit.Â
