Walmart's application is reviewed rather than instant — prepare your catalog quality before you apply, not after, since a thin or inconsistent starting catalog is one of the most common reasons an application is rejected outright (see Marketplace Application Rejected). See the Walmart hub for full detail behind any item below.

Before you apply

  • Business verification documents ready (legal entity, tax ID) before starting the application — gathering these mid-application, if the session doesn't save cleanly, can force you to restart.
  • A clean, complete starting catalog prepared — thin or low-quality catalogs are a common rejection reason. Aim for genuinely complete product data (real photography, full descriptions, correct identifiers) on every item you submit, not a placeholder set.

Between approval and going live

  • Fulfillment decision made: Walmart Fulfillment Services (WFS) or self-fulfillment — this affects Buy Box (Featured Offer) eligibility similarly to how FBA affects Amazon's Buy Box (see Buy Box Concepts Explained).
  • Pricing modeled against Walmart's current category referral fee, not assumed to match Amazon's rate for the same category — the two platforms' referral fees differ by category and shouldn't be assumed identical.
  • Listing content complete and meeting Walmart's attribute/image requirements — these are not identical to Amazon's, so a listing copied verbatim from Amazon often needs real adjustment, not just reformatting.
  • Walmart Seller Scorecard metrics understood before launch, so you know what's being tracked from day one rather than discovering the specific metrics after receiving a warning.
  • Walmart Connect advertising account set up if you plan to advertise at launch — setting this up in advance means you can start advertising as soon as your listing goes live, rather than losing early visibility days to setup delays.

The full checklist

  • Business verification documents ready (legal entity, tax ID) before starting the application.
  • A clean, complete starting catalog prepared — thin or low-quality catalogs are a common rejection reason.
  • Fulfillment decision made: Walmart Fulfillment Services (WFS) or self-fulfillment.
  • Pricing modeled against Walmart's current category referral fee.
  • Listing content complete and meeting Walmart's attribute/image requirements.
  • Walmart Seller Scorecard metrics understood before launch, so you know what's being tracked from day one.
  • Walmart Connect advertising account set up if you plan to advertise at launch.

A worked example: preparing a catalog that clears review

A seller preparing to apply with ten SKUs invests time before applying to ensure every SKU has a verified UPC, professional (not phone-camera) photography, and a complete attribute set matching Walmart's specific category requirements — rather than the minimal content that would have been sufficient to simply create the listings after approval. This upfront investment is specifically aimed at clearing Walmart's review-based application on the first attempt, since a rejection and reapplication cycle can cost weeks compared to the days it takes to prepare a genuinely complete catalog upfront.

What to do in the first weeks after going live

  • Monitor your Seller Scorecard from the first order, the same way you would Amazon's account health dashboard — see Marketplace Seller Policies 101 for why early metrics are especially sensitive at low order volume.
  • Track Featured Offer eligibility if you're on a shared listing, applying the same diagnostic logic as Amazon's Buy Box (price, fulfillment speed, account health).
  • Compare early Walmart Connect ad performance against Amazon Ads if you're running both, since a less-saturated ad auction on Walmart can sometimes produce a more efficient cost per result than the same budget on Amazon.

Common mistakes

  • Applying with a thin or placeholder catalog, assuming it can be built out after approval — Walmart's review process specifically evaluates catalog quality as part of the approval decision itself.
  • Copying an Amazon listing directly into Walmart's format without adjusting attributes and images to Walmart's specific requirements.
  • Assuming Walmart's referral fee for a category matches Amazon's rate for the same category without checking Walmart's current fee schedule directly.
  • Not setting up Walmart Connect until well after launch, losing early visibility opportunity in a comparatively less-competitive ad auction.

FAQs

How long does Walmart's application review typically take? It varies and isn't instant the way Amazon's often is for non-gated categories — budget meaningfully more lead time than you would for an Amazon application, and use that lead time to make sure your starting catalog is genuinely complete rather than rushed.

Can I use the same product photography and descriptions from my Amazon listings? You can use the same underlying photography and descriptions as a starting point, but you'll typically need to adjust formatting, attributes, and sometimes image specifications to meet Walmart's specific requirements rather than uploading them unchanged.

Is WFS required to be competitive on Walmart Marketplace? Not strictly required, but similar to Amazon's FBA, using WFS is generally favorable for Featured Offer eligibility and can meaningfully improve competitive placement compared to self-fulfillment, especially in categories with WFS-enrolled competitors.
