ERP Integration Strategies for Cloud, API, and AI Readiness

Executive Summary

Companies have invested significantly in Enterprise Resource Planning (ERP) solutions to automate business processes like finance, purchasing, and inventory management. While these systems have improved performance, the monolithic design and extensive customizations of traditional ERPs have led to inflexibility and hindered innovation.

Modern ERP environments are evolving towards best-of-breed cloud applications and APIs, offering users seamless, anytime, anywhere access to data and functionalities. This shift provides flexibility but emphasizes the critical need for integration between these diverse applications.

The complexity of ERP integration is further amplified by modern supply chains, which require deep collaboration across global ecosystems of buyers, suppliers, logistics providers, financial institutions, and other parties, relying on automated data exchange between ERP systems and external partners.

In today's dynamic economic climate, resilient and agile business models are essential. The American SAP User Group (ASUG) identifies ERP integration as key to organizational success. However, transitioning to cloud ERP environments and embracing technologies like Artificial Intelligence (AI) presents significant complexity and time challenges. This white paper explores the pivotal role of integration in modernizing ERP environments, navigating B2B integration complexities, mitigating risks, ensuring security and compliance, and fostering long-term business growth.

Defining the Modern ERP Ecosystem

Gartner's ERP strategy reports indicate a shift from monolithic to modular, cloud-first ERP architectures, defining ERP as an ecosystem of cloud-native applications and APIs. Organizations are moving from large, on-premises ERP suites to collections of best-of-breed cloud applications tailored to specific business needs.

Modern ERPs are characterized by cloud-based applications using modernized code and APIs, delivering continuous capabilities to users globally. Major vendors like SAP, Oracle, and Microsoft are leading this transformation with cloud-based ERP solutions. This evolution also creates opportunities for smaller, cloud-native providers offering specialized applications.

Beyond replacing paper-based processes, organizations are implementing digital technologies to reimagine business models. These digital transformation initiatives necessitate connecting to and leveraging data from numerous source systems and applications, many of which must integrate seamlessly with the core ERP.

The dynamic nature of this environment highlights the integration challenge. To maximize the benefits of ERP and digital investments, organizations require seamless integration for effective information flow across business applications and their extended partner ecosystem.

The Pivotal Role of ERP Integration

The shift to modular ERP systems and best-of-breed cloud applications increases the importance of ERP integration for synchronizing data and automating processes between the ERP and other systems. Integration requirements vary significantly in complexity.

While pre-configured integration solutions are available for common use cases, system customizations, advanced processing rules, and niche applications can make integrations difficult to configure, support, and maintain.

External B2B integrations, enabling data exchange with suppliers, customers, and partners, add further complexity. These require coordinating activities across multiple organizations, each with its own systems and processes. With 44% of transactional data in ERPs originating from external sources, efficient management of this complexity is vital for modern business operations.

As ERP systems become more fragmented, integration is essential for digitizing and automating key business processes. Without it, many tasks would be manual, leading to inefficiency, errors, cost, and risk. Organizations often face significant business repercussions, such as lost revenue and customers, due to integration strategy challenges.

Integration is also crucial for transitioning to modern ERP systems. Gartner reports that 40% of ERP implementations underachieve due to underinvestment in integration, often cited as a major factor hindering digital transformation success. Implementing modern ERP systems like SAP S/4HANA®, Microsoft® Dynamics 365 Business Center, Oracle® NetSuite, and Oracle Fusion often catalyzes the modernization of integration capabilities.

Top 5 Focus Areas for API and EDI Integration in ERP Projects

Organizations modernizing their ERP systems should focus on five key integration areas:

Minimizing Risk and Disruption

ERP migrations carry significant risks. Greenfield migrations can cost around $24 million USD over seven years, with large organizations potentially spending much more. These projects are complex, require stakeholder collaboration, and can take years. Ensuring minimal business disruption during transitions is critical. Approximately 80% of SAP customers cite managing disruption as a key requirement for ERP migration, with minimal business disruption being the top requirement for SAP S/4HANA implementations. A strategic integration approach, starting early with thorough requirements gathering and testing, can significantly reduce disruption.

Minimizing ERP Customization

Many ERP implementations have been heavily customized. The American SAP User Group (ASUG) found that 91% of its members use customized code. These customizations can be difficult to maintain and complex to handle during modernization, with 92% of SAP users finding existing customizations problematic for their SAP S/4HANA migration. Cloud application principles advocate for minimizing custom code. Desired functionalities should ideally be handled outside the ERP, possibly in separate applications or through modern integration solutions that support advanced logic, business rules, and data validation.

Avoiding Project Delay and Budget Overrun

Project delays are costly and impact business strategies. ERP implementations can cost three to four times their original budgets and take up to 30% longer than expected. A robust integration strategy, supported by detailed insights and planning, can help mitigate these delays. Ensuring adequate resourcing for integration throughout the project is crucial, especially if integration is not considered a strategic priority early on.

Avoiding Creation of Integration "Spaghetti"

As organizations digitally transform and modernize ERP strategies, they face a proliferation of applications and systems. The average number of applications used by an organization ranges from under 200 to nearly 1,000 and is growing. While not all applications require integration, this complexity impacts ERP integration efforts.

A survey by IDG found that 63% of companies experienced ERP connectivity loss due to integration issues, with many feeling their current tools are insufficient. Challenges often stem from integration strategies using multiple tools and platforms without centralized governance. The same survey indicated only 33% of respondents use a centralized platform for most integrations, while 59% use a mix of tools.

Over time, ERP implementations can become heavily customized. Unifying integration strategies and consolidating technologies can improve governance, increase efficiency, enhance visibility, and reduce ecosystem complexity.

Addressing the Skills Challenge

Integrating ERP and other applications often requires specialist skills that may not be readily available internally. A shortage of integration skills is a major challenge during ERP modernization. IDG research shows 86% of organizations experienced delays with ERP integration, with a lack of expertise being the primary reason.

Lack of Integration Expertise is the No. 1 Reason Behind ERP Integration Project Delays

Securing the right integration skills is essential for successful ERP migrations, given the existing shortage of skilled staff. Gartner predicts that by 2027, only 30% of companies will have sufficient data quality to leverage advanced AI in ERP, partly due to skills and integration challenges.

The Future of ERP Integration

Integration needs are growing in both volume and variety. There is an increasing demand for simple integration tasks manageable by business users via self-service tools. Simultaneously, complex integration involving multiple application calls, advanced data transformations, and intricate business logic is also rising, crucial for optimizing digital business processes. With 91% of organizations seeking new ERP integration solutions, modern integration platforms are clearly needed.

Businesses require future-proofed integration strategies that meet current needs while allowing for agility and scalability. This involves careful selection of integration partners and solution providers, along with extensive enterprise coordination. Organizations must assess existing integration solutions and develop roadmaps to build necessary capabilities, guiding their digital transformation goals.
