Introduction

There are three common approaches to ERP integration and the right choice depends on your data volume, the ERP vendor and your real time requirements.

  1. Middleware integration. A dedicated tool such as Boomi, Celigo, Patchworks or MuleSoft sits between Magento and the ERP, handling field mapping, retries and scheduling. Middleware is the fastest route to production and the easiest to maintain but adds a monthly cost.
  2. Direct API integration. A custom Magento module, built through bespoke Magento development, connects directly to the ERP REST or SOAP API. This is the most flexible approach and the cheapest long term, but requires ongoing developer maintenance as both platforms evolve.
  3. File based integration. CSV or XML files exported from the ERP and imported into Magento on a schedule. This is suitable only for low volume operations or nightly sync requirements and is not recommended for real time stock.

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

We also integrate with

Oracle E-Business Suite · Unleashed Software · Torque WHMS · Cin7 · OrderWise · Xero · QuickBooks · Custom / Bespoke ERP systems

Magento NetSuite Integration

Real-time Magento NetSuite integration via SuiteTalk REST and SOAP APIs. We sync products, prices, stock, orders, customers, fulfilments and refunds bi-directionally, with a queue-backed retry layer that handles NetSuite's governance limits without losing data. Multi-subsidiary, multi-currency and B2B price levels all supported.

Magento SAP Integration

Magento SAP integration covering both SAP Business One (B1) and SAP S/4HANA. We use SAP's Service Layer, OData and BAPI interfaces, and integrate via API Mesh on Adobe Commerce or a dedicated middleware layer on Magento Open Source. Common scope: master data, pricing conditions, sales orders, deliveries, billing documents and customer accounts.

Magento Sage Integration

Magento Sage integration across Sage 50, Sage 200, Sage Intacct and Sage Business Cloud. Sage 200 typically integrates via the SDATA Web API or Sage Provider, with order, customer, stock and financial sync. We handle the Sage-specific quirks around tax codes, nominal codes and analysis dimensions.

Magento Dynamics 365 / Dynamics NAV Integration

Magento Dynamics NAV integration (now Business Central) via OData V4 and Web Services. Dimensions, item categories, customer pricing groups and warehouse locations all supported. We have also integrated with Dynamics 365 Finance & Operations for larger enterprises.

Magento Brightpearl & Linnworks

For retailers running Brightpearl or Linnworks as the operational backbone, we integrate Magento as another sales channel. Order ingestion, stock allocation, fulfilment status and tracking all sync automatically with no manual reconciliation.

Custom & Bespoke ERP Systems

If your ERP system for Magento is bespoke, in-house, or a heavily-customised legacy platform, we build a dedicated REST or SOAP connector with the same queue, retry, monitoring and reconciliation tooling we use for off-the-shelf ERPs.

Magento ERP

  • Orders: Automatic export with status updates, tracking, and fulfilment confirmation
  • Customers: New registrations, address changes, and account updates
  • Invoices: Automated financial record sync without manual reconciliation

ERP Magento

  • Stock Levels: Real-time inventory across all warehouses, preventing overselling
  • Products: Update once, publish everywhere. Data, attributes, and categories
  • Pricing: Customer-specific pricing, tier discounts, and promotional rates

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

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

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.

  1. 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. 2. Build & Configure We develop the integration module, configure API endpoints, and build the data transformation layer to ensure clean, consistent data exchange.
  3. 3. Test & Validate Comprehensive testing with real data to validate every sync point, error handling path, and edge case before going live.
  4. 4. Deploy & Monitor Go live with full monitoring and alerting in place, ensuring any issues are caught and resolved immediately.

Joanie Clothing

We built a bespoke integration between Magento and Torque WHMS for Joanie Clothing, enabling real-time order processing, stock synchronisation, and automated returns handling. Alongside this, we integrated Advanced Commerce search to deliver fast, intelligent product discovery across their catalogue.

  • Custom Torque WHMS integration for order & stock sync
  • Automated refund process with advanced logic
  • Advanced Commerce search integration
  • Real-time inventory visibility across all channels
  • Bespoke reporting package

How long does a Magento ERP integration take to build?

A standard integration covering orders, stock, products and customers runs 6 to 10 weeks. Complex scenarios with real time stock across multiple warehouses or custom pricing rules run 10 to 16 weeks.

Does the integration work in real time or on a schedule?

Both are possible. Stock levels and order status typically run in real time, while product data and pricing often run on a 15 minute or hourly schedule to reduce API load. We configure the right cadence per data type.

What happens if the ERP is offline?

Our integrations queue failed API calls and retry with exponential backoff, log every sync attempt, and alert your team when sync failures exceed a threshold. No data is lost when the ERP is temporarily unreachable.

Do I need middleware like Boomi or Celigo?

Not always. For straightforward order and stock sync a direct API integration is usually cheaper and faster. Middleware becomes worthwhile when you need to connect Magento to multiple downstream systems, or when the ERP vendor requires it. Our B2B Magento builds often use middleware when pricing and catalogue data flows into multiple places.

Can you integrate Magento with a legacy ERP that has no API?

Yes. We have built integrations using SOAP web services, EDI, SFTP file drops and direct database connections for older ERPs. The approach depends on what the ERP exposes.

How much does Magento ERP integration cost?

Typical integrations range from £8,000 to £30,000 depending on scope. We work at a flat £100 per hour and provide a fixed scope estimate after a free consultation.
