Headless commerce is soon to be the new norm for agility-starved eCommerce brands. As forecasted, global headless commerce adoption is projected to reach $7.6 billion by 2032, and an increasing number of companies are abandoning monolithic architectures.
Being able to craft custom frontends using technologies like React or Vue while keeping the backend steady is game-changing. However, there is a catch: headless commerce ERP integration is not a plug-and-play solution.
Historical ERPs were designed to tightly couple systems. Bolting them onto decoupled frontends introduces complexity, often resulting in significant issues. This approach disrupts order synchronization, inventory visibility, and customer management. In contrast, implementing it well provides speed, flexibility, and data harmony.
ERP Integration For Headless eCommerce Builds
Fast APIs, clean data, zero manual patchwork
This white paper is all open. We will examine how headless commerce integration with ERP is achieved, including the API and middleware choices available, as well as platform-specific advice for Shopify, BigCommerce, and Magento, along with some battle-hardened best practices.
What is Headless Commerce, and how does ERP fit in?
Headless commerce is the separation of the frontend (what customers see) from the backend (where data resides). It enables brands to create lightning-fast, device-agnostic storefronts using new frameworks, without sacrificing their powerful commerce engines in the back.
That’s where headless eCommerce ERP comes in.
ERPs manage your inventory, product list, prices, orders, customers, and logistics. In a headless implementation, the front end doesn’t communicate with the back end at all. It retrieves data via APIs. This requires integrating an ERP and a headless CMS to sync real-time data between systems.
However, monolithic ERP systems were designed for integrated frontend and backend commerce platforms, presupposing that the frontend and backend are merged. This approach results in slower integrations, complex workflows, and low scalability when combined with headless architecture.
To address that, you require modern ERP integrations developed in the language of headless systems—modular APIs, real-time sync, and adaptive middleware.
Popular Headless Commerce Platforms That Support ERP Integration
Headless commerce platforms today are ERP-ready right out of the box. They’re provided with APIs, SDKs, and pre-built connectors to ensure easy ERP integration. Let’s explore how Shopify headless ERP integration works with industry giants.
Shopify Headless ERP Integration
Shopify’s Hydrogen framework and Storefront API give you complete control over the frontend experience.
ERP systems integrate via:
Custom REST/GraphQL APIs
Middleware platforms (e.g., Celigo or MuleSoft)
Ideal for syncing order information, customer profiles, and fulfilment with platforms such as NetSuite or Microsoft Dynamics.
Smoothly integrates with frontend frameworks such as Vue Storefront or Gatsby.
ERP sync functionalities:
Real-time inventory syncing through webhooks
Custom middleware solutions
Third-party iPaaS tools such as Dell Boomi
Magento Headless Integration
Magento 2 is compatible with headless commerce with PWA Studio.
Ideal for brands that require deep customisation and control.
ERP integration possibilities:
Middleware application software
Custom service buses for ERP and frontend data syncing
GraphQL for frontend query support
Additions as an option
Headless Commerce Platforms with ERP integration:
CommerceTools: Complete API-based, ideal for microservices architecture and ERP synchronization.
JAMstack: Integrate ERP hooks with tools like Netlify to build lean but robust storefronts.

APIs and Middleware for ERP integration
The essence of ERP integration lies in how your systems talk to each other, through APIs and middleware. Here’s how to interpret it:
REST vs GraphQL
REST is commonly used in legacy ERPs and is easier to understand.
GraphQL is more flexible, so frontend applications only ask for the data they need.
Use GraphQL for headless frontends on new stacks; REST works fine for basic ERP sync use cases.
Webhooks vs Polling
Webhooks send data in real-time—perfect for real-time order updates and inventory sync.
Polling checks for changes periodically. Simpler to set up but less effective.
Middleware Tools
Middleware bridges ERP and the frontend by reorganizing, routing, and syncing data. Some of the most popular middleware tools are:
MuleSoft: Enterprise-class integration with pre-built connectors.
Dell Boomi: Drag-and-drop iPaaS software, perfect for syncing ERP, CRM, and commerce data.
Celigo: Perfect for mid-market businesses with NetSuite or other SaaS ERPs.
Zapier: Lightweight automation for small-scale ERP synchronization.
Custom-Built Service Layer: If off-the-shelf fails, craft your own using Node.js or Python microservices.
They take ERP API integration to the consistency, reliability, and scalability level.
Custom ERP Integration for Headless Storefronts
And then there are times when the out-of-the-box ERP connectors just do not translate to your business logic. That is when you require custom development.
When Out-of-the-Box ERP Connectors Fail to Cut It
You might require custom ERP integration for headless storefronts when you have:
Special pricing structures such as tiered discounting, bundling, or customer-based pricing.
Multi-region warehousing based on fulfillment zip code or stock-level-dependent.
B2B storefronts with account-based catalogues, workflows, or terms of payment.
Synchronization of multi-storefront across brands, languages, or geographies.
How to Build Custom Middleware
Decouple all data sync logic (price, inventory, orders, etc.) with a microservices architecture.
Route the calls between frontend, backend, and ERP using an API gateway (e.g., AWS API Gateway or Kong).
Utilise message queues (e.g., RabbitMQ or Kafka) to process high-volume updates without compromising performance.
Custom integrations are the agility you require when your headless storefront and ERP aren’t communicating in the same language.
Best Practices for Headless Commerce ERP Integration
An effective integration isn’t a tool issue—it’s an issue of planning, architecture, and implementation. Here’s what successful teams do:
1. Always Map Out Data Flow First
Map out how data moves between systems before you ever write code.
Define:
Which application owns each set of data
What data syncs, and what triggers it
What format and direction does data move in?
2. Use Modular ERP Systems
Pick ERPs like Odoo, NetSuite, or Acumatica that support flexible, modular APIs. Avoid monolithic, closed systems.
3. Focus on Real-Time Sync for Critical Data
Orders, inventory, and customer actions should update in near real-time. Use webhooks and message queues where possible.
4. Implement Logging, Alerts, and Fallbacks
When integrations fail—and they will—you’ll need:
Error logs
Alerting systems (e.g., Slack or PagerDuty)
Backup sync processes
5. Match Sync Frequency to Business Logic
Not everything should be synchronized in real time. Examples:
Prices: Sync hourly
Inventory: Sync 5–10 minutes
Product content: Sync daily
