Approaches to ERP integration

What are the integration techniques of ERP? Here, we have collected all ERP integration best practices and approaches for data unification. Choose the one that is most appropriate for your company.

ERP integration types: point-to-point integration, iPaaS, enterprise service bus, API integration.

Point-to-point integration

Point-to-point integration is the most straightforward approach, where two systems are directly connected with custom code or pre-built connectors. The strengths of this approach include complete integration control with no third-party software included, increased data accuracy and integrity, concise integration needs addressed, and low-barrier entry. Point-to-point integration is easy to set up and manage initially; its cost is low for simple integrations. 

Negative effects are the lengthy integration process, the amount of manual support needed, no centralized place to monitor integrations, and each integration being conducted separately for each system. Additionally, the approach is not scalable, challenging to maintain as the number of integrations grows. It can become complex and prone to errors.

Point-to-point integration is best suited for businesses with simple IT infrastructure.

API integration

What is API ERP integration? API management leverages open APIs the ERP system provides and other applications to establish connections. You, or a third-party tool, manage the data exchange and transformations. The advantages of such an approach include subscription plans, simple and standardized API management, and plenty of teams ready to provide high-quality support. 

The drawbacks include the following: apps do not offer all necessary integrations, are not preconfigured for event-based architecture, integrations may not fulfill business requirements, and have no end-to-end automation.

The solution best serves companies with no advanced IT infrastructure beginning their digital transformation.

Enterprise service bus (ESB) integration

Enterprise service bus integration is a specific approach to integrating systems, particularly ERPs, that uses a central hub to facilitate communication and data exchange, i.e., apps communicate with one another via a middleware layer. In this enterprise resource planning systems integration, communication between apps goes through connectors and adaptors.

The strengths of such an approach include less dependency on specific apps, high scalability, centralization for managing integrations, and good connecting legacy and on-premises systems. The weaknesses include ill-adaptation for cloud apps, not supporting intelligent automation, having to be manually configured, and requiring technical proficiency/complex maintenance.

This ERP software integration approach suits companies with large and mixed (on-premises and cloud) IT environments.

Integration platform as a service (iPaaS)

Integration platform as a service represents a cloud-based platform that provides tools and services for building, deploying, and managing integrations between applications. It offers pre-built connectors for various applications, including ERPs, databases, and SaaS platforms.

The other iPaaS features include visual drag-and-drop interfaces, data transformation capabilities, and workflow automation features. The pros of such an integration approach include: it gives a centralized view of all integrations, as a rule, complies with data protection requirements, accelerates the workflow, has automated updates, is a scalable, future-proof solution, supports hybrid data models, and allows easy cost forecast because of subscription-based pricing.

The cons include that the solution requires technical knowledge, may be time-consuming and costly, takes longer to achieve ROI, and has limitations for complex data flow.

Overall, this approach fits best for businesses with a cloud-based IT environment.
