Project details

Walmart Marketplace Flat File Error Correction & Catalog Upload Expert — I fix rejected item, spec, pricing, and inventory feeds and get them resubmitted successfully through Seller Center.

Instead of endlessly re-uploading and hoping an error disappears, I do a root-cause, line-by-line diagnosis of your flat file to find exactly what's breaking it: spec ID mismatches, invalid attributes, GTIN/UPC conflicts, formatting errors, and category mapping issues. Every fix comes with documentation so the same error doesn't resurface on your next upload.

I work with Walmart sellers, brands, agencies, and eCommerce businesses managing large or fast-moving catalogs — where a single rejected feed can mean lost sales, buy box visibility, and wasted time. If your listings are stuck, your feed keeps bouncing, or your catalog has recurring errors, I can find the fix and get you live again.

Gilgit, Pakistan - 1:01 pm local time
I manage Walmart Marketplace stores end-to-end — account setup, item and flat file uploads, WFS fulfillment, Walmart Connect PPC, order management, and Listing Quality Score recovery — so sellers don't have to juggle five specialists to keep one store running.

What end-to-end means when I run your account:
- Seller Center account setup, onboarding, and ongoing account health monitoring
- Item setup (single + variation) and flat file bulk uploads — item spec, price, inventory feeds
- GTIN/UPC exemption handling and spec ID error resolution
- SEO-optimized listing content: titles, descriptions, backend keywords
- Listing Quality Score (LQS) audits and recovery
- Walmart Connect PPC — campaign build, keyword targeting, ACoS reduction
- WFS inventory management, replenishment timing, and fulfillment coordination
- Order management, returns handling, and day-to-day store operations
- Pricing and Buy Box monitoring

WHERE I START WITH MOST CLIENTS:
- Walmart flat file errors or rejected uploads — I fix formatting, spec ID mismatches, and GTIN/UPC issues so uploads go through clean the first time.
- Low Listing Quality Score (LQS) — I audit content, images, and backend fields to push scores up and unlock better placement.
- Walmart Connect ad spend with poor ROI — I rebuild campaigns around actual buyer search terms instead of broad-match guessing.
- WFS inventory issues — I manage replenishment timing and fulfillment coordination to stop stockouts and overstock fees.
- Accounts that need one person to own the whole operation instead of five freelancers who don't talk to each other.

RECENT RESULTS

Managed end-to-end WFS operations at Comverse (Jul 2023–Jan 2024) — item setup, listing quality recovery, fulfillment coordination, and order error reduction
Reduced ACoS from 45% → 22% while scaling ad-attributed sales 3.1x over 6 months
Bulk-uploaded 600+ SKUs via flat file across Walmart and Amazon with zero rejected batches

SECONDARY SPECIALTY — AMAZON SELLER CENTRAL For sellers running both platforms, I also manage Amazon listings, PPC (Sponsored Products/Brands/Display), A+ Content, Brand Registry, and FBA shipment planning — so Walmart and Amazon stay in sync instead of running as two disconnected operations.

TOOLS I USE DAILY DataSpark, Helium 10, Jungle Scout, SellerAmp, Keepa, AZInsight, Scan Unlimited, Google Sheets
