Your ERP holds the truth about your business — stock levels, pricing, order status, customer accounts. When it's not talking to Magento in real time, you get overselling, manual data entry, and customers chasing orders you've already dispatched. We build the integrations that fix that.
We have hands-on experience integrating Magento with a wide range of ERP and warehouse management systems, from enterprise platforms to bespoke solutions.
For businesses running Adobe Commerce, we also leverage the platform's built-in B2B features to create even deeper ERP connectivity for trade accounts, company hierarchies, and negotiated pricing.

What We Synchronise
Our integrations handle the complete data lifecycle between Magento and your ERP, ensuring consistency across every touchpoint.
Orders
Automatic order export with real-time status updates, tracking numbers, and fulfilment confirmation pushed back to Magento. No more copying orders between systems or chasing missing shipments.
Stock Levels
Bi-directional inventory sync across all warehouses and sales channels. Stock updates flow in real time, preventing overselling during peak trading and keeping availability accurate everywhere.
Customer Data
Customer records, addresses, credit terms, and account hierarchies synchronised between Magento and your ERP. One source of truth, no conflicting records.
Products
Product data, descriptions, attributes, and categories managed in your ERP and automatically reflected in your Magento catalogue. Update once, publish everywhere.
Pricing
Customer-specific pricing, tier pricing, and promotional rates pulled from your ERP in real time. Your trade customers always see the right price without manual updates.
Invoices
Automated invoice generation and synchronisation, keeping financial records aligned across both systems without manual reconciliation.
Real-Time Sync vs Batch Sync
Not every data flow needs to happen instantly. We design each integration to use the right sync mode for the right data type, balancing speed with system performance.
Real-Time Sync
Data flows instantly between Magento and your ERP the moment a change occurs.
Stock levels — prevent overselling
Order export — immediate fulfilment
Pricing updates — always accurate
Tracking numbers — instant customer updates
Batch Sync
Data is synchronised on a schedule — every 5 minutes, hourly, or daily — for less time-sensitive operations.
Product catalogue updates
Customer data sync
Invoice reconciliation
Historical data migration
Most integrations use a combination of both. We'll recommend the right approach during the discovery phase based on your data volumes, ERP capabilities, and business requirements.
Common ERP Integration Challenges We Solve
ERP integrations are notoriously difficult to get right. Here are the problems we see most often and how we solve them.
Unreliable Sync
The Problem:
Orders failing silently between Magento and the ERP, leading to missed shipments and frustrated customers
Our Solution:
Real-time validation and intelligent retry logic that ensures every order is processed, with instant alerts if any issues arise
Stock Discrepancies
The Problem:
Overselling due to delayed stock updates between the warehouse and Magento, causing cancellations and lost trust
Our Solution:
Bi-directional real-time stock synchronisation that keeps inventory accurate across all channels and warehouses
Costly Middleware
The Problem:
Middleware platforms adding annual licensing fees on top of implementation and maintenance costs, with another vendor to manage and another point of failure
Our Solution:
Direct API integrations built into Magento, eliminating middleware fees entirely. You own the integration, we maintain it, and there's no third-party dependency adding cost and complexity
Our Integration Process
Every ERP integration follows our proven methodology to ensure reliable, maintainable, and performant data flows.
1. Discovery & Mapping
We audit your existing systems, map data flows between Magento and your ERP, and identify potential challenges before writing a single line of code.
2. Build & Configure
We develop the integration module, configure API endpoints, and build the data transformation layer to ensure clean, consistent data exchange.
3. Test & Validate
Comprehensive testing with real data to validate every sync point, error handling path, and edge case before going live.
4. Deploy & Monitor
Go live with full monitoring and alerting in place, ensuring any issues are caught and resolved immediately.
