How to Ship on Walmart Marketplace in 2026: Seller's Guide

Walmart Marketplace is the fastest-growing e-commerce platform in the US, with over 100,000 sellers. But Walmart has higher shipping standards than most platforms — they expect Amazon-level delivery performance with strict metrics.

Here's everything you need to know about shipping on Walmart in 2026.

Two Fulfillment Options

1. Walmart Fulfillment Services (WFS)

2. Seller-Fulfilled (Merchant Fulfilled)

You handle shipping yourself.

How it works:

Order comes into your Walmart Seller Center

You create a label and ship it

You handle returns

Walmart's Shipping Requirements

Walmart monitors several shipping metrics:

Failing these metrics can result in listing suppression or account suspension.

Setting Up Shipping Templates

Walmart uses shipping templates to define your delivery promises:

Standard Shipping

• Transit time: 3–5 business days
• Handling time: 1–2 business days
• Total delivery: 4–7 business days

Expedited Shipping

• Transit time: 2 business days
• Handling time: 1 business day
• Total delivery: 3 business days

Two-Day Shipping

• Available through WFS or if you can guarantee 2-day delivery
• Significant boost in search ranking and Buy Box wins

Creating Shipping Labels

Option 1: Walmart's Shipping Labels

Walmart offers discounted shipping labels through Seller Center using their carrier rates.

Option 2: Your Own Labels via atoship

Create labels through atoship for potentially better rates:

Import Walmart orders (via API or manual entry)

Compare USPS, UPS, and FedEx rates

Purchase the cheapest label

Upload the tracking number to Seller Center

Option 3: Connect atoship to Walmart

atoship integrates with Walmart Marketplace — orders sync automatically, and tracking numbers push back to Walmart when labels are created.

Carrier Recommendations

For Standard Shipping

• USPS Ground Advantage: Best for items under 10 lbs
• UPS Ground: Best for items 10–70 lbs
• FedEx Ground: Alternative to UPS

For Two-Day Shipping

• UPS 2nd Day Air: Guaranteed 2-day
• FedEx 2Day: Guaranteed 2-day
• USPS Priority Mail: 1–3 days (not guaranteed but often arrives in 2)

Packaging Requirements

• Use plain brown boxes (no competitor branding — no Amazon boxes!)
• Include a packing slip
• Use appropriate cushioning for fragile items
• No marketing materials from other platforms
• Walmart may provide packaging guidelines for specific categories

WFS vs. Seller-Fulfilled: Decision Guide

Tips for Success

Ship same day when possible — exceeding delivery expectations boosts your seller score

Always use tracking — 99%+ valid tracking rate is required

Use atoship for rate comparison — Walmart doesn't penalize you for using your own labels

Set conservative delivery estimates — promising 5 days and delivering in 3 is better than promising 3 and delivering in 4

Monitor your scorecard — check Seller Center weekly for shipping metric trends

Frequently Asked Questions

Do I need WFS to sell on Walmart?

No. You can sell as a seller-fulfilled merchant. However, WFS gives you access to the Walmart+ free shipping badge and 2-day delivery, which significantly boosts visibility and sales.

Can I use my own shipping labels on Walmart?

Yes. You can use any carrier and purchase labels through any platform, including atoship. Just make sure to upload the tracking number to Seller Center promptly.

What happens if I miss Walmart's shipping metrics?

Walmart will send warnings and may suppress your listings. Continued failures can result in account suspension. The most critical metric is the 95% on-time shipping rate.

How does Walmart's shipping compare to Amazon's?

Walmart has similar performance expectations but is somewhat more lenient. Amazon's metrics are stricter, but both platforms require 95%+ on-time delivery and 99%+ valid tracking.
