3PL fulfillment for Walmart Marketplace sellers

Simpl Fulfillment connects to your Walmart Marketplace account so orders route to us automatically and tracking flows back. Your Walmart, Shopify, Amazon, and website orders ship from the same inventory pool. 98.8% of orders received before 12pm CT ship the same day.

Starting at $7/order, including picking, packing, and postage, Simpl provides ecommerce fulfillment from one warehouse in Austin, Texas. Walmart orders shipped by Simpl are seller-fulfilled, not WFS orders. The TwoDay badge is not automatic and depends on Walmart’s seller-fulfilled requirements.

How Simpl Handles Walmart Marketplace Orders

Simpl Fulfillment is a D2C 3PL that fulfills your Walmart Marketplace orders alongside every other channel you sell on — from one inventory pool, no platform lock-in.

Here’s how it works:

  • We connect to your Walmart Marketplace account. Orders route to us automatically and tracking flows back. Simpl also connects to Shopify, Shopify Plus, BigCommerce, WooCommerce, Squarespace, Amazon, eBay, Etsy, and TikTok Shop, so one inventory pool covers all of it, with real-time inventory sync across channels. Need something custom? Ask us about API integrations.
  • We ship same-day. Orders received before 12pm CT ship the same day, via UPS, USPS, or FedEx — carrier included in the flat per-order rate.
  • We pick accurately. 99.99% order accuracy, and if we make a mistake we correct it at our cost, including return shipping and re-fulfillment.
  • Pricing is flat. Starting at $7/order, which includes picking, packing, and postage. Simpl has a $750/month account minimum billed pay-the-difference — you’re only charged the gap if a month’s order billing comes in under $750. It’s a floor, not a flat fee.
  • You get a real person. Every client gets a dedicated account manager — reachable by email, with same-day (often faster) responses.

Your inventory stays with an independent fulfillment partner. The same units ship a Walmart order, a Shopify order, or a wholesale pallet — and you run all of it from one place.

What Makes a Walmart-Ready 3PL

Not every 3PL handles Walmart well. Walmart holds sellers to on-time shipping and delivery standards, and a 3PL that misses them puts your account health at risk. Here’s what to check before you pick one:

  • Marketplace connection. The 3PL should connect to your Walmart Marketplace account so orders flow in and tracking flows back automatically.
  • On-time shipping that meets Walmart’s SLAs. Look for a same-day or next-day ship commitment you can count on.
  • Real-time inventory sync. Stock levels should update across every channel as orders ship, so you don’t oversell.
  • EDI and integration support. If you’re also doing retail or wholesale, the 3PL needs EDI, routing guides, and ASN support.
  • Accuracy you can measure. Ask for the pick-and-pack accuracy rate and what happens when an order goes out wrong.

A 3PL that clears all five can run your Walmart orders without putting your seller standing at risk, and it can do the same for every other channel at the same time. One that falls short on shipping speed or inventory sync will cost you badges, buy-box position, and eventually account health. The bar is real, so it’s worth asking these questions before you move inventory anywhere.

These are the same criteria Simpl is built to meet.

WFS or a 3PL?

Walmart Fulfillment Services (WFS) stores and ships inventory in Walmart’s network. Walmart also offers Multichannel Solutions (MCS) to fulfill off-Walmart orders. An independent 3PL like Simpl keeps your Walmart, Shopify, Amazon, and website fulfillment with a partner outside that marketplace network.

Compare the channels you need, the fulfillment workflow, and the total cost for your catalog. Read our guide to how Walmart Fulfillment Services works and what it costs for WFS fees and requirements.

WFS vs. Self-Fulfillment vs. 3PL

There are three ways to get your Walmart orders out the door: let Walmart do it (WFS), do it yourself (self-fulfillment), or hand it to a 3PL. They differ on four things that matter to your bottom line — what they cost, how much control you keep, which channels they can serve, and how well they scale as you grow. Here’s how they compare.

ScalingScales with Walmart, tied to their fee scheduleCapped by your own hours and spaceScales without you hiring or leasing more space
Custom packagingStandard Walmart packagingWhatever you buyBranded inserts, kitting, custom boxes

WFS handles Walmart orders, with MCS available for off-Walmart orders. Self-fulfillment gives you control but takes your time as you grow. An independent 3PL runs fulfillment across your channels outside a marketplace’s network. The right answer depends on how many places you sell and how much of your day you want back. If a 3PL is where you land, our comparison of the best small business 3PLs shows which providers fit which sellers.

When WFS Makes Sense

WFS is a solid choice when your business lines up with how it’s built:

  • You sell only on Walmart Marketplace. If Walmart is your one channel, keeping inventory inside Walmart’s network is clean and simple.
  • You want the delivery badge without managing logistics. WFS handles fast shipping and the badge that comes with it.
  • Your catalog moves fast. High-velocity SKUs spend less time in storage, so cubic-foot storage fees stay low relative to sales.
  • You don’t need custom packaging or kitting. If a standard box out the door is fine, WFS covers it.

If that’s your business, WFS can be the least-friction path. The math works best when Walmart is your whole world and your products turn quickly.

When a 3PL Is the Better Choice

A 3PL does more when your business outgrows a single channel or needs flexibility WFS can’t offer:

  • You sell on more than one channel. Shopify, Amazon, TikTok Shop, wholesale — a 3PL fulfills all of them from one inventory pool, so you’re not splitting stock across separate systems or forecasting for each one.
  • You need your inventory to stay flexible. With a 3PL, the same units can ship a D2C order, a Walmart order, or a wholesale pallet, in your own packaging. WFS can ship other channels through Multichannel Solutions, but that stock stays in Walmart's network and ships in unbranded boxes.
  • You want branded unboxing, kitting, or subscription assembly. A 3PL builds custom packaging, kits, and subscription boxes into the workflow.
  • You’re managing retail or wholesale flow. B2B fulfillment with EDI, routing guides, and ASNs sits outside what WFS does.

The core issue is operational control. If Walmart is one of several places you sell, decide whether Walmart’s network and packaging rules fit every ecommerce channel or whether you want a 3PL to run those channels, branded packaging, and wholesale work together.

WFS vs. 3PL Alternatives Compared

If you’ve decided a 3PL beats keeping everything inside Walmart’s network, here are the fulfillment options sellers weigh most often, and the kind of business each one fits best.

  1. Simpl Fulfillment. Best for multi-channel D2C brands that also sell on Shopify, Amazon, and TikTok Shop. Ships your Walmart Marketplace orders from the same inventory pool as every other channel you sell on. Flat pricing starting at $7/order, same-day shipping, and a dedicated account manager. No marketplace lock-in.
  2. ShipBob. Best for brands that want a large multi-warehouse network for distributed inventory. A national fulfillment network with warehouses across multiple regions. Pricing is quote-based and scales with the network, which tends to fit larger operations.
  3. ShipMonk. Best for high-SKU DTC brands that want an all-in-one software platform. Fulfillment paired with built-in inventory and order-management software, aimed at brands with large catalogs that want everything in one dashboard.
  4. Red Stag Fulfillment. Best for heavy, bulky, or high-value products that need careful handling. A specialist in oversized and high-value goods, with accuracy guarantees built around products that most standard 3PLs treat as exceptions.
  5. Cahoot. Best for sellers who want a peer-to-peer fulfillment network for fast ground delivery. A merchant network model that positions around fast, low-cost ground shipping by fulfilling from partner locations closer to the buyer.
  6. Amazon Multi-Channel Fulfillment (MCF). Best for sellers already deep in FBA who want to fulfill off-Amazon orders. Uses your existing FBA inventory to ship orders from other channels. Keeps stock inside Amazon's network, the same trade-off WFS makes with Walmart's.

For brands selling across Walmart, Shopify, Amazon, and TikTok Shop, Simpl ships every order from one inventory pool starting at $7/order, with same-day shipping and a dedicated account manager. No marketplace holds your stock hostage.

Frequently Asked Questions

Can a 3PL fulfill Walmart Marketplace orders?
Yes. Simpl connects to your Walmart Marketplace account so orders route to us automatically and tracking flows back. We ship from the same inventory pool as your Shopify, Amazon, and website orders. These are seller-fulfilled Walmart orders, not WFS orders.
Do Walmart orders shipped by a 3PL automatically get the TwoDay badge?
No. A 3PL-shipped Walmart order is seller-fulfilled. The TwoDay badge is not automatic and depends on Walmart's seller-fulfilled requirements. Simpl ships orders received before 12pm CT the same day via UPS, USPS, or FedEx; same-day shipping is not a promise of two-day delivery or badge eligibility.
When should a Walmart seller use a 3PL instead of WFS?
Consider an independent 3PL when you want Walmart, Shopify, Amazon, and website orders handled from one inventory pool outside a marketplace's network. Walmart also offers Multichannel Solutions (MCS) for off-Walmart orders, so compare the channel connections and fulfillment workflow you need. WFS can make sense when Walmart is your main channel and its fulfillment model fits your catalog.
How much does Simpl charge to fulfill Walmart orders?
Pricing starts at $7/order, which includes picking, packing, and postage. There's a $750/month account minimum, billed pay-the-difference: you're only charged the gap if a month's order billing comes in under $750.
Does Simpl fulfill orders from channels other than Walmart?
Yes. Simpl fulfills Walmart Marketplace orders alongside Shopify, Shopify Plus, BigCommerce, WooCommerce, Squarespace, Amazon, eBay, Etsy, and TikTok Shop orders from one inventory pool.
