Client Overview

An eCommerce Agency Managing Marketplace Growth for Brands, Manufacturers, and Resellers

The client is a well-established eCommerce marketplace management agency serving over a dozen brands across North America. Positioned as a full-service provider, the agency helped manufacturers, distributors, and resellers strengthen their presence across major online marketplaces, including Amazon, eBay, and Walmart.

With a particular focus on the automotive parts and accessories, home and garden, and sports and leisure verticals, the agency had built a reputation for delivering hands-on marketplace expertise to clients who lacked the internal resources to manage multi-channel eCommerce at scale.

Engagement Requirements

White-Label Resource Support Across Marketplace Operations Management

The agency required a skilled, experienced team that could be deployed under a white-label arrangement to serve its clients directly. This meant the team would operate under the agency's name—not SAMM Data's—and would need to adhere to the agency's internal workflows, timelines, and client-facing standards.

Tasks assigned to the SAMM Data team included:

  • Sourcing product data from appropriate channels and populating listing templates for 17 active brand accounts.
  • Creating and uploading product listings across Amazon, eBay, Walmart, and brand-owned eCommerce sites.
  • Optimizing existing listings for improved search visibility and conversion performance.
  • Managing product inventory levels and pricing updates across all active sales channels.
  • Editing product images to meet the specific upload guidelines of each marketplace and storefront.
  • Handling channel and marketplace support requests on behalf of the agency's clients.

Key Challenges

Managing Accuracy, Platform Complexity, and Process Compliance

Taking on a white-label role for a multi-client agency brought a level of operational complexity that demanded both technical depth and strict process discipline. Each challenge below required a targeted response before consistent delivery was possible.

  • The agency managed its clients across several marketplace management platforms simultaneously—Linnworks, SureDone, AdLister, and Volo—in addition to more familiar tools, such as Rithum. Operating across all four with equal proficiency required rapid onboarding.
  • The agency used a proprietary seller activity management application to coordinate task assignments, time tracking, and team communications. The team had no prior exposure to this system, which required structured client-led training before operations could begin.
  • As the team was serving the agency's own clients under a white-label agreement, standards for responsiveness, accuracy, and process adherence were significantly higher than a typical service engagement. Any error or delay had direct consequences for end clients and reflected on the agency's reputation.
  • The automotive parts and accessories category required a high degree of domain knowledge. Incorrect part numbers, fitment data, or technical attributes could result in incompatible product listings for buyers, making near-perfect data accuracy a non-negotiable baseline.

Execution Approach

End-to-End White-Label Marketplace Management Across 17 Client Accounts and Multiple Marketplace Platforms

We deployed seven dedicated resources to manage marketplace work for seventeen of the client’s customers. The team operated as a direct extension of the client under a confidential and transparent working model.

The client trained our team on product categories and proprietary marketplace processes. We then aligned access, account setup, and execution workflows to match the client’s operating structure.

Product Listing Across Marketplaces and eCommerce Stores

Using Linnworks, SureDone, Ad-Lister, and Volo, the team uploaded products for 17 brands across Amazon, eBay, and Walmart. For brands with their own eCommerce storefronts, listing specialists handled product uploads on Shopify, Magento, and WordPress, ensuring data consistency across all channels.

Search-Driven Listing Optimization

To improve organic visibility and conversion performance, the team conducted keyword research and applied optimized content across product titles, bullet points, descriptions, and backend fields on Amazon, eBay, and Walmart. Each listing was reviewed against marketplace-specific ranking criteria before publishing.

Structured Product Data Extraction

Dedicated data specialists sourced product attributes from manufacturer websites, competitor listings, and physical and digital catalogs. All collected data was cleaned, validated, and mapped to listing templates before being used to create new records or resolve gaps in existing ones.

Platform-Compliant Product Image Editing

Product images were processed individually for each marketplace and storefront. Specialists performed background removal, color correction, shadow adjustments, and resizing—ensuring every image met the technical and aesthetic standards of the platform it was listed on.

Inventory Synchronization and Automated Pricing Management

The team monitored stock levels across all 17 client accounts using multi-channel management platforms, keeping inventory synchronized across Amazon, eBay, and Walmart. Restocking requests were submitted to suppliers proactively, and pricing updates were automated across all active channels to eliminate manual errors.

First-Line Marketplace and Channel Support

When clients encountered listing suppressions, restricted category flags, or account-level technical issues, the team managed all communication with Amazon, eBay, Walmart, and other platform support teams. This ensured timely resolution with minimal disruption to ongoing sales activity.
