Casper Sleep: Shopify Plus Migration and Embedded Development Partnership
When the platform itself becomes the bottleneck
Casper sells mattresses, bedding, and sleep accessories direct to consumers, online and in store. For a DTC brand, this commerce platform is the business. Casper had outgrown theirs.
Years of custom development on Salesforce Commerce Cloud had left Casper with a brittle, specialist-dependent codebase. Non-technical team members couldn't touch basic workflows without pulling in a developer. Retail locations were running legacy POS systems held together by workarounds. And a sprawling integration layer across PIM, ERP, fulfillment, and marketing tools required constant maintenance just to stay operational.
Nothing was broken. It was just expensive and hard to move fast.
Moving Casper to the Shopify ecosystem
We started with an audit. Before writing code, we mapped the full architecture. That assessment drove everything: the platform decision, the integration design, and the scope of each workstream. It gave both teams a picture of what migration would require.
From there, the work had three main tracks.
E-Commerce and OMS Migration. We replaced Salesforce OMS with Shopify's native order management, built around a new middleware layer that created a cleaner separation between Shopify, the fulfillment engine, and the ERP. Customer service workflows were rebuilt natively in Shopify before cutover.
Shopify POS Implementation. We replaced the legacy POS across every retail location, starting from what Shopify handles out of the box and methodically closing the gaps: shipping logic, bundle handling, split shipments, sales attribution, role-based permissions. We also built Casper's training program from scratch for enterprise deployment.
Post-Migration Development. After go-live, we kept building. A custom bundle app, a metafield-powered mattress comparison tool, bundle upsell modules, and a full WCAG audit across desktop and mobile.
A platform built for the whole team
Casper moved from a system that required specialist knowledge at every turn to one any team member can navigate. Knowledge concentration risk is gone. The integration layer is simpler. And release cadence shifted to a structured sprint cycle with full cross-team visibility.
When your infrastructure stops fighting you, guess what, you get to build.
