Seller Management Platform

The Vision & Challenge

A B2B ecommerce services provider built its business on aggregating products from independent sellers and distributing them across major online sales channels. Their model depends on volume and quality, curating vast catalogs while maintaining strict standards for every partner on their platform.

As the company grew, its manual processes became a serious liability. Onboarding sellers, verifying legal documents, approving product lines, and managing fulfillment was an inefficient, multi-step process handled by internal administrators. This operational drag limited how quickly they could add new sellers and introduced a constant risk of human error.

Our team was brought in to design and build a central operations hub. The objective was to create a single, authoritative system to manage the entire seller lifecycle, enforcing business rules automatically and giving administrators the tools they needed to focus on quality control, not paperwork.

Project challenges

  • The existing manual workflow for seller onboarding and verification was inconsistent, leading to compliance risks and delays.
  • Product data from sellers was fragmented and required manual entry into distribution systems, creating a high risk of error and inventory mismatches.
  • Internal teams and sellers lacked a centralized way to track status or receive timely alerts, causing bottlenecks in product approvals and order fulfillment.

Solutions

  • We developed a multi-step, role-based workflow. Sellers are guided through a mandatory process of document submission, while Admins and Officers have specific dashboards to review, approve, or reject applications.
  • An integration with the Linnworks API was built to act as the master system for product data. Once a seller’s catalog is approved, it automatically synchronizes, ensuring data integrity before being pushed to sales channels.
  • A custom notification engine was implemented to send automated alerts for key events. This system informs admins of new registrations, notifies sellers of product status changes, and warns of fulfillment issues.

Guided Compliance Workflow

The platform enforces a strict, multi-stage process for all new sellers. Each applicant must complete a series of steps, from agreeing to terms to submitting signed legal documents. The system then routes the application to internal Admins and Officers for sequential review and approval. This removes ambiguity from the process, ensures every partner is fully compliant before their account is activated, and creates a clear audit trail for every decision.

Centralized Catalog Management

We connected the platform directly to the partner's Linnworks and Shopify accounts. When an administrator approves a seller's products within the tool, that data is programmatically sent to the appropriate external systems. This removes the need for manual data entry, prevents incorrect or unapproved items from being listed, and ensures inventory information is consistent across all sales channels. It is the bridge between internal quality control and external commerce.
