100% Workflow Efficiency Achieved with an End-to-End Marketplace Liquidation Platform
A U.S.-based e-commerce company needed to turn surplus and returned Amazon and Walmart inventory into a scalable, repeatable revenue stream. We built an end-to-end automated liquidation platform with direct marketplace integrations, eliminating manual sourcing, pricing, approvals, and logistics—unlocking a fully scalable liquidation business model with 100% workflow efficiency.

Efficiency Improvement Achieved

The client is a US-based company working with Amazon and Walmart sellers across the United States and Canada. The project focused on launching a new business model for monetizing residual marketplace inventory by automating the sourcing, approval, and resale of surplus and returned goods through the client’s own distribution channels.

THE CHALLENGE
The manual marketplace liquidation process required a dedicated platform to enable full automation.
The client set out to launch a new model for liquidating surplus and returned inventory from Amazon and Walmart sellers. Their existing approach relied on manual product discovery, direct seller communication, and one-off negotiations, making it slow, costly, and impossible to scale. To move forward, they needed a centralized, scalable platform capable of automating sourcing, pricing, approvals, and logistics end to end.
Complex Integration with Amazon & Walmart Marketplaces
To enable automated liquidation, the system needed deep integration with Amazon and Walmart ecosystems. This included accessing product data, tracking inventory availability, supporting automated pricing, and triggering warehouse pickup workflows—none of which were possible with the client’s existing manual processes.
Lack of a Unified UI to Support the Business Workflow
There was no centralized interface for sellers to submit inventory or for the client to review, approve, and manage liquidation deals. Existing workflows relied on emails and spreadsheets, creating delays, inconsistencies, and operational risk.
THE SOLUTION
An Automated Platform for Marketplace Inventory Liquidation
We built an automated platform that enables Amazon and Walmart sellers to liquidate surplus and returned inventory without manual coordination, while giving the client full control over sourcing, pricing, approvals, and logistics.
The platform replaces manual seller outreach and negotiations with a continuous, automation-driven process. Sellers independently submit inventory for liquidation, and once eligible products become available, the system automatically proposes pricing, validates product data, and executes the buyout workflow. Inventory pickup from Amazon and Walmart warehouses is organized automatically, without human intervention.
Marketplace API Integration for Automated Buyouts
We implemented API-based integrations with Amazon and Walmart to automate product data ingestion, availability checks, and buyout workflows. The system continuously monitors inventory updates and enables automatic purchasing as soon as eligible products become available, eliminating the need for manual coordination.
Unified Platform UI for Seller Self-Service and Deal Control
We built a dedicated user interface based on Django Admin to support the full liquidation workflow. Sellers can independently submit surplus inventory for liquidation, while the client can review offers, manage approvals, and oversee execution from a single platform. The UI acts as the control layer for automated pricing, sourcing, and logistics operations.
THE RESULT
From Manual Liquidation to a Scalable, Automated Operation
The client received a fully automated liquidation platform that handles inventory sourcing, availability validation, pricing, approvals, and warehouse pickups for Amazon and Walmart sellers—end to end, without manual coordination.
This platform allows the client to liquidate surplus and returned inventory at scale, launch a new revenue model without increasing operational headcount, and eliminate manual seller outreach and deal negotiations entirely. By automating the full workflow and integrating directly with marketplace APIs, the client gained real-time inventory visibility, faster deal execution, and consistent, repeatable operations.
