Walmart Fulfillment

We store, pack and ship your Walmart Marketplace orders from our Southern California warehouse.

For Walmart sellers

Ship on Time, Every Time

Walmart Marketplace holds sellers to shipping-time standards, so late orders can hurt your account. Packing every order yourself works until a busy week, or a week away, makes it slip.

Sonic Fulfillment is a third-party logistics (3PL) warehouse in Southern California. We keep your inventory on our shelves and pick, pack and ship your Walmart orders, with tracking on every package.

Your stock can also fill orders from Amazon, eBay, Etsy, Shopify and your other channels, so you are not splitting inventory between warehouses.

Common questions

Walmart Questions

What Walmart sellers ask before moving their fulfillment to us.

Do you fulfill Walmart Marketplace orders?

Yes. We store your inventory and pick, pack and ship your Walmart orders, with tracking on every package.

How do my Walmart orders reach you?

It depends on how your store is set up. Tell us where you sell and what tools you use, and we will confirm how orders reach us before you send any inventory.

Can I sell on other marketplaces too?

Yes. The same warehouse can hold stock for your other channels, such as Shopify, Amazon, eBay, TikTok Shop and Whatnot. See all services.

How is pricing set?

You get a quote built around your products and order volume. It lists the rate for receiving, storage, pick and pack, packaging and shipping, and your invoice uses the same lines.

Where are you located?

We are based in Southern California, close to Los Angeles, Orange County and the ports of Long Beach and Los Angeles. We send the receiving address for your inventory when you sign up.
