Overview

Inverge is a multi-tenant commerce and operations platform designed to help retailers and brands manage complex ecommerce operations across multiple sales channels, warehouses, and partner networks.

Rather than operating as a traditional storefront, the platform functions as operational infrastructure — coordinating product data, inventory, orders, fulfillment workflows, and financial integrations across dozens of external systems.

Since its inception, the platform has supported:

250+ merchants | 1.3M+ orders | $90M+ in transactions | 50+ integrations

Technical Highlights

The platform evolved over more than a decade of development into a large-scale operational system supporting hundreds of merchants and complex multi-channel commerce workflows.

Key technical characteristics include:

  • Multi-tenant architecture supporting hundreds of independent merchant accounts
  • 50+ external integrations across ecommerce platforms, marketplaces, logistics providers, and accounting systems
  • Incremental architecture migration from a PHP monolith to a Node.js API with a Next.js frontend without downtime
  • Event-driven workflows coordinating order processing, inventory updates, and fulfillment operations
  • Automated product data ingestion pipelines processing catalog feeds from multiple external systems
  • Custom order routing engine supporting complex fulfillment rules across warehouses and 3PL providers
  • Production AWS infrastructure architected, deployed, and maintained for reliability and scalability
  • Security and operational compliance, including passing third-party security reviews and audits

Infrastructure and Cloud Architecture

The platform’s cloud infrastructure was designed and maintained entirely within AWS.

Key components of the infrastructure include:

  • EC2 instances hosting application services
  • Elastic Load Balancers (ELB) distributing traffic across application nodes
  • AWS WAF protecting the platform against common web threats
  • CloudFront providing global CDN delivery
  • S3 for asset storage and media management
  • Route53 managing DNS and routing
  • Lambda functions supporting asynchronous processing and automation
  • API Gateway powering API endpoints for external integrations
  • DynamoDB supporting high-throughput operational workloads
  • SQS and SNS coordinating asynchronous messaging between services
  • SES for transactional email delivery

The infrastructure supported continuous operation of the platform while processing millions of transactions and coordinating dozens of external integrations.

System Architecture

The platform coordinates dozens of external systems across the commerce lifecycle.
Inverge acts as the central system of record for product data, inventory, and order workflows.

By centralizing operational workflows within a single system, Inverge reduces the operational overhead required to manage multi-channel ecommerce businesses.

The Challenge

Growing ecommerce businesses typically operate across many disconnected systems:

  • online storefronts
  • marketplace channels
  • fulfillment providers
  • shipping carriers
  • accounting software
  • product data feeds

Managing these systems independently creates operational complexity. Product data must be duplicated across platforms, inventory frequently falls out of sync, and fulfillment workflows often require manual reconciliation.

The goal of the platform was to create a single operational system capable of coordinating these workflows while remaining flexible enough to integrate with many external services.

The Operational Workflow

At the core of the platform is an automated workflow that manages the lifecycle of product data, orders, fulfillment, and financial reconciliation.

This workflow ensures that product data, inventory levels, order status, and financial records remain synchronized across the entire commerce ecosystem.

Key Systems Built

Over time, Inverge evolved into a suite of operational systems supporting the full lifecycle of ecommerce operations.

Multi-Channel Commerce Infrastructure

Integrations with Amazon, eBay, Walmart, Shopify, CommerceHub, Faire, and other platforms allow merchants to manage product listings, inventory, and orders from a single system.

Catalog Ingestion and Product Data Pipelines

Automated pipelines ingest product data from CSV feeds, Shopify stores, NetSuite, and other sources, transforming and standardizing data to automatically generate marketplace listings.

Warehouse and Fulfillment Management

A warehouse management system supports both internal fulfillment operations and third-party logistics providers with optimized picking workflows, shipping integrations, and real-time inventory tracking.

Dropshipping Network Infrastructure

Retail partners can sell products from shared catalogs, with orders automatically routed to the appropriate merchant for fulfillment and automated billing.

Circular Marketplace

Customers can send in used products in exchange for store credit, enabling a circular resale marketplace built on the same product catalog and fulfillment infrastructure.

Architecture Evolution

The platform began as a full-stack PHP application and evolved into a modern API-driven architecture.

A Node.js API layer powers integrations and new applications, including a tablet-based POS built with React Native.

The primary interface was gradually migrated to a Next.js frontend while maintaining compatibility with the original system, enabling an incremental migration without downtime.

Impact

Over more than a decade of development, the platform became the operational backbone for hundreds of ecommerce merchants.

Key metrics include:

  • 250+ merchants supported
  • 1.3M+ orders processed
  • $90M+ in transactions
  • 50+ external integrations
