Walmart Listings to WFS Conversion

I have between 11 and 50 existing electronics listings on Walmart Marketplace that must be migrated from regular seller-fulfilled status to Walmart Fulfillment Services (WFS). The catalog data is already live, but before I can switch fulfillment methods Walmart is requiring that each SKU be fully WFS-compliant, including a correctly attached Safety Data Sheet (SDS).

What I need from you
• Audit every listing against the current WFS item spec in Seller Center.
• Update all mandatory attributes, dimensions, and shipping details for electronics so they pass the WFS item-setup checker.
• Prepare or complete the SDS section for each SKU—some sheets may be missing or incomplete, so please assume a full review is needed.
• Upload the updated item files (Excel bulk sheet or API, whichever you prefer) and confirm that each SKU successfully flips to “WFS Ready” status.
• Provide a simple hand-off report listing the SKUs, submission timestamps, and any flags that required manual resolution.

All work happens inside my Seller Center account. I’ll give you delegate access once we start. Familiarity with Walmart’s Bulk Item Setup template, WFS size tiers, and SDS attachment workflow is essential. If you have previous success moving electronics listings to WFS, let me know; it will speed up onboarding.
