E-commerce Integration Platform

An integration layer for Atlas Commerce that keeps inventory and order data synchronized across storefronts, marketplaces, and fulfillment.

Customer: Atlas Commerce (demo)

Atlas Commerce sells across their own storefront and several third-party marketplaces, previously reconciled through a manual, error-prone nightly process. We built a real-time integration layer that keeps inventory and orders synchronized across every channel.

Challenge

Atlas Commerce's nightly batch reconciliation process meant inventory counts could be stale for up to 24 hours, occasionally leading to overselling on one channel when stock had already sold out on another.

Solution

We replaced the nightly batch process with webhook-driven, near-real-time synchronization across the storefront, marketplace integrations, and fulfillment provider. Inventory updates propagate within seconds of a sale on any channel, and the system is built to handle partial failures gracefully — a temporarily unreachable marketplace API doesn't block updates to the others.

Architecture

A central inventory service acts as the source of truth, receiving webhook updates from each sales channel and fulfillment provider, and pushing corrected counts back out. Each integration is isolated behind its own retry-and-backoff logic, so a failure or rate limit on one channel doesn't cascade to the others. An events log captures every inventory change for troubleshooting and reconciliation auditing.

Key features

Near-real-time sync

Inventory updates propagate across channels within seconds, not overnight.

Isolated channel integrations

A failure on one marketplace's API doesn't block updates to the others.

Central inventory source of truth

One authoritative service reconciles updates from every channel.

Full change audit log

Every inventory change is recorded for troubleshooting and reconciliation.

Integrations

Storefront platform

Direct webhook integration for order and inventory events.

Marketplace channels

Real-time sync with third-party marketplace APIs.

Fulfillment provider

Automated status updates from pick, pack, and ship events.

Representative outcomes

Eliminated stale inventory windows

Inventory counts reflect near-real-time status instead of a 24-hour-old snapshot.

Reduced overselling incidents

Cross-channel stock conflicts dropped significantly after real-time sync went live.

Resilient to individual channel outages

A marketplace API issue no longer affects other channels' data.
