Step 1: Log In

Sign in to your Walmart Seller Center and go to the Shipping Plans page.

Step 2: Create a Shipping Plan

Click Create Plan and select the items you want to send.

Step 3: Set Up Packing and Prep

Prep Service Fees and Unplanned Charges

When you use WFS Prep Services, you’ll pay a per-unit fee for planned prep work such as poly-bagging or labeling.

If your items arrive at the fulfillment center without meeting Walmart’s prep standards, you’ll be charged an unplanned prep fee.

Planned Prep Fees

Unplanned Prep Fees

If your items need unexpected prep at the fulfillment center, Walmart will fix them for you — and charge extra.

Note: Walmart does not guarantee fixed pricing across time, category, or item size. These numbers change and sometimes vary by fulfillment center.

Why This Matters

• Selecting the correct prep service in advance saves time and money.

• Non-compliant products can lead to delays, extra fees, or refusals.

• Common issues include missing barcodes, damaged packaging, or missing expiry dates.

Benefits of Using WFS Prep Services

1. Save Time on Operations

WFS Prep Services remove a major operational burden for Walmart sellers. Instead of spending hours labeling, bagging, and packaging inventory, Walmart handles prep directly at the fulfillment center.

This is especially useful for sellers managing multiple SKUs or shipping large inbound volumes, where even small prep mistakes can slow down receiving or trigger extra fees.

2. Reduce Costly Compliance Errors

One of the most common reasons sellers face delays or unplanned charges is non-compliant inventory. Missing barcodes, incorrect packaging, or incomplete labeling can all result in added costs once products reach a WFS facility.

By using WFS Prep Services, your inventory is prepared by Walmart’s own fulfillment team according to current standards, which helps reduce errors and rejected shipments.

3. Faster Receiving and Product Availability

Inventory that is properly prepped typically moves through Walmart’s receiving process more efficiently. When items arrive ready for storage, they are checked in faster and made available for sale sooner.

This can be especially important during peak periods when fulfillment centers handle high inbound volumes.

4. Easier Scaling as Your Business Grows

As order volume increases, managing prep internally becomes harder and more expensive. WFS Prep Services allow sellers to scale without adding warehouse space, staff, or complex workflows.

This is one reason many growing sellers move toward marketplace-managed fulfillment models, similar to how programs like Amazon FBA support scaling for high-volume sellers.

5. More Predictable Costs and Fewer Surprises

While WFS Prep Services add a per-unit cost, they help reduce unexpected expenses caused by unplanned prep fees or shipment refusals. Knowing prep costs in advance makes margin planning more predictable.

Walmart recommends reviewing current prep pricing directly in Seller Center, as fees may change over time. You can also reference Walmart’s official WFS fee documentation for the latest guidance.

When WFS Prep Services Make the Most Sense

WFS Prep Services are especially helpful if you:

• Ship large or frequent inbound orders

• Manage many SKUs

• Have faced unplanned prep fees in the past

• Want faster receiving with less hands-on operational work

Smaller sellers with strong in-house prep processes may choose alternatives, but for growing operations, WFS Prep Services often reduce friction and operational risk.

Alternatives to WFS Prep Services

WFS Prep Services are convenient, but they’re not the only option. Depending on your order volume, team size, and cost structure, one of the alternatives below may be a better fit for your business.

1. Prep Inventory In-House

Some sellers choose to handle all prep work internally. This means labeling, poly bagging, bundling, and packaging products yourself before shipping them to Walmart fulfillment centers.

This approach works best if you already have:

• Warehouse space or a prep area

• Trained staff

• A clear understanding of Walmart’s prep and labeling rules

Prepping in-house gives you full control over quality and branding, but it also increases operational workload. Any mistakes can still result in unplanned prep fees once inventory reaches Walmart.

2. Use a Third-Party Logistics Provider (3PL)

Many sellers outsource prep to a third-party logistics provider (3PL) that specializes in Walmart and Amazon-style fulfillment requirements. These providers handle labeling, packaging, storage, and shipment to Walmart fulfillment centers on your behalf.

Popular options include fulfillment companies that already support [Walmart Fulfillment Services (WFS)] workflows and understand inbound compliance requirements.

This option is useful if:

• You don’t want to manage prep operations internally

• You ship large or frequent inbound orders

• You want flexibility across multiple sales channels

However, 3PLs often charge for storage, handling, and specialized services, which can add up. Sellers should compare total costs against WFS Prep fees before committing.

3. Hybrid Approach (In-House + WFS or 3PL)

Many experienced sellers use a hybrid model. They prep simpler SKUs in-house while using WFS Prep Services or a 3PL for bulk shipments, fragile items, or complex bundles.

This approach offers:

• Cost control for simple inventory

• Scalability for high-volume or seasonal products

• Reduced risk of compliance errors during peak periods

For example, you might handle labeling for low-volume SKUs internally and rely on WFS Prep Services during Q4 when inbound volumes spike and fulfillment centers become congested.

Conclusion

WFS Prep Services aren’t mandatory, but they can make a meaningful difference if you’re shipping at scale or struggling with compliance issues. When products arrive correctly labeled and packaged, they move through Walmart’s fulfillment network faster and with fewer surprises.

For some sellers, using WFS Prep Services is worth the added cost for the time saved and consistency gained. Others may prefer in-house prep or a trusted 3PL. The right choice depends on your volume, team capacity, and tolerance for operational risk.

What matters most is preparation. Sellers who understand Walmart’s standards and plan ahead avoid delays, reduce unplanned fees, and create a smoother experience for both their business and their customers.
