Custom & Legacy ERP Integration

When Standard Connectors Don't Exist

Not every ERP is NetSuite or SAP. Many growing brands run on proprietary systems, industry-specific platforms, or legacy software that predates modern APIs. These systems still hold critical business data: inventory, orders, pricing, customer records, and financials.

We build the bridges that connect these systems to modern commerce platforms. No matter how your ERP exposes data, we can work with it.

Integration Approaches

API-Based (When Available)

If your ERP has a REST, SOAP, or GraphQL API, we build direct integrations using the same event-driven, queue-based architecture we use for NetSuite and SAP. This is the most reliable and lowest-latency approach.

File-Based Exchange

Many legacy systems export data as CSV, XML, or fixed-width files dropped to an SFTP server. We build file watchers that:

• Monitor SFTP directories for new files
• Parse and validate file contents
• Transform data to match commerce platform schemas
• Load data via API with error handling and retry logic
• Archive processed files for audit trails

Database-Level Integration

For systems with accessible databases, we can read data directly:

• Read-only views on the ERP database for inventory and product data
• Change Data Capture (CDC) for real-time event detection
• Staging tables for bi-directional data exchange
• Careful isolation to avoid impacting ERP performance

EDI Integration

For brands working with large retailers, distributors, or 3PLs that require EDI:

• X12 and EDIFACT document processing
• VAN (Value Added Network) connectivity
• Direct AS2 connections
• Document mapping and transformation
• Functional acknowledgment handling

Common Legacy Systems We've Connected

We've built integrations for a wide range of systems including:

• Custom-built inventory management systems
• Industry-specific platforms (apparel PLM, food distribution, manufacturing MRP)
• Older versions of Sage, Epicor, and Infor
• Spreadsheet-based "systems" that need to be formalized
• Access databases and FileMaker Pro setups

If your system holds the data your commerce platform needs, we can connect them.
