OVERVIEW

Project overview

Our client, a mid-sized eCommerce fulfillment company in the United States, managed inventory, orders, and shipping across multiple online stores. Their operations involved Shopify and Magento, several shipping providers, and manual processes that slowed fulfillment and increased costs.

VARTEQ's team developed a custom warehouse management system (WMS) that brings inventory tracking, order processing, shipping rate comparison, and label generation into one platform. The system connects eCommerce stores with logistics providers, automates repetitive tasks, and supports higher order volumes.

WHERE THEY STARTED

The challenge

The client needed to manage growing fulfillment operations without adding more manual work. Disconnected systems made it difficult to maintain accurate inventory records, process orders efficiently, and select suitable shipping options.

Disconnected inventory and order management

Inventory, orders, and quotations were spread across multiple Shopify and Magento stores. Without centralized synchronization, the team faced inventory mismatches and fulfillment delays.

Complicated shipping decisions

Each order required evaluating different carriers based on shipping rates and delivery times. Manual comparisons slowed order processing and made it harder to control shipping costs.

Manual shipping label generation

Printing shipping labels required substantial staff time. The process created bottlenecks, increased the risk of errors, and delayed order dispatch.

Limited logistics integration

The company needed reliable connections with UPS, USPS, Endicia, and ShipStation to automate shipping operations through a single system.

WHAT WE BUILT

The solution

  1. Centralized warehouse management system

    A custom WMS that manages inventory, orders, and shipping activities across multiple eCommerce stores.

    • Built an architecture designed for high-volume order handling
    • Created automated workflows for order management
    • Supported inventory and order synchronization across connected stores

  2. Automated shipping rate comparison

    A shipping comparison engine that evaluates available carriers based on delivery time and cost.

    • Integrated shipping rate analysis into order processing
    • Automated carrier selection based on shipping requirements
    • Reduced the need for manual rate comparisons
    • Supported faster shipping decisions and lower fulfillment costs

  3. Logistics API integrations and label automation

    Connections with third-party shipping providers that automate label generation and reduce manual fulfillment tasks.

    • Integrated UPS, USPS, Endicia, and ShipStation APIs
    • Automated shipping label generation
    • Connected carrier services with warehouse workflows
    • Reduced manual printing work and processing errors

  4. Shopify and Magento synchronization

    Real-time integrations that connect the warehouse management platform with the client's eCommerce stores.

    • Synchronized inventory and order information
    • Connected Shopify and Magento through APIs
    • Centralized order tracking across multiple storefronts
    • Supported consistent fulfillment processes as the business expanded to additional platforms

  5. Deployment and workflow optimization

    A phased rollout designed to introduce the new platform without disrupting existing warehouse operations.

    • Tested integrations and automated fulfillment workflows
    • Deployed the system in stages
    • Provided staff training
    • Supported adoption and ongoing workflow optimization
