B2B integrations are vital to ensuring global supply chains and IT services run seamlessly across different business entities. 

The B2B integration solution market is undergoing massive growth, with a current market size of $8.3 billion expected to grow to $22.6 billion by 2023.

This article evaluates the best-fit B2B integration solutions for enterprise businesses and IT service management across the spectrum from self-service tools to fully-managed services. 

What is a B2B integration platform?

A B2B integration platform connects applications, data sources, and business services between organizations and their partners, customers, and vendors. The B2B integration landscape is estimated to be $8.3 billion in annual revenues in 2025, including several distinct platform types:

iPaaS (Integration Platform as a Service)

  • Cloud-based platforms providing self-service tools for building and maintaining integrations
  • Visual workflow builders, pre-built connectors, and low-code development environments
  • Examples: Boomi, MuleSoft, Workato, SnapLogic
  • Operational model: Customer manages all integration operations

Enterprise integration suites

  • Comprehensive platforms from major enterprise vendors (IBM, Microsoft, Oracle, SAP)
  • Deep integration with vendor's ecosystem of products
  • Support for both cloud and on-premises systems
  • Operational model: Customer manages integrations within vendor ecosystem

API management platforms

  • Unified API solutions that consolidate multiple third-party APIs
  • Reduce complexity by providing single integration points
  • Examples: Merge.dev, Kombo
  • Operational model: Customer integrates once, platform manages multiple endpoints

Managed integration service providers

  • Operate integrations as a service on behalf of customers
  • Take full responsibility for monitoring, maintenance, and continuous optimization
  • Examples: ONEiO
  • Operational model: Provider manages entire integration lifecycle

The critical distinction in B2B integrations centers on operational responsibility. Traditional B2B integration platforms provide tools for customers to manage integrations themselves (for example through EDI/API connections). Managed service providers operate integrations as a service, handling monitoring, maintenance, and adaptation to changes without customer intervention.

Key selection criteria for B2B  integration solutions

When evaluating B2B integration solutions for 2026, enterprise IT leaders should prioritize:

1. Operational model

Does the platform provide just tools, or does it operate integrations as a service? Organizations face significant integration complexity challenges, with the operational burden of managing integrations yourself creating substantial risk.

2. AI-readiness

Can the platform support the data access patterns required for AI initiatives? Modern AI deployments require seamless access to data across hybrid and multi-cloud environments without extensive manual preparation.

3. Scalability without complexity

As your integration needs grow, does complexity scale proportionally, or does the platform manage that complexity operationally?

4. Adaptation to change

When systems update or business processes change, do integrations require manual rework, or do they adapt automatically?

5. Total cost of ownership

Look beyond subscription fees to include internal resource requirements, maintenance overhead, and the cost of integration failures.

Integration Ops: The future of B2B integration

The integration landscape is undergoing the same transformation that DevOps brought to software development and SecOps brought to security. McKinsey's 2025 research on the State of AI reveals that organizations must restructure entire processes and workflows to integrate AI effectively, moving beyond tools that merely increase individual productivity. This requires seamless integration with partner organizations.

Traditional integration approaches (project-based implementations, manual maintenance, reactive troubleshooting) no longer scale for modern enterprise requirements. 

The shift to Integration Ops addresses key limitations of B2B integrations through:

  • Continuous operations Integrations are monitored 24/7 with proactive issue resolution before problems impact service delivery.
  • Automated compatibility management As APIs change, authentication updates occur, and systems evolve, Integration Ops ensures connections remain functional without manual intervention.
  • Standardized delivery Proven methodologies ensure consistent, high-quality integration management across all customers, eliminating the variability of custom-built integrations.
  • Scalable architecture Whether managing a few integrations or thousands, the operational model supports seamless expansion without proportional cost increases.

This operational approach becomes increasingly critical as enterprises scale AI initiatives across their partner network and supply chain.

Bottom line on B2B integration solutions

B2B integrations are experiencing massive growth thanks to ever more digitalized supply chains and complex IT service networks. As demand for B2B integrations is expected to grow, businesses increasingly face the choice of building or buying integrations that are capable of connecting their entire data ecosystem.

Many enterprise IT leaders have discovered that traditional project-based integrations no longer scale for modern B2B integration. The fragility of point-to-point connections, the operational burden of manual maintenance, and the inability to adapt to constant change create bottlenecks that constrain digital transformation and AI initiatives.

Integration Ops represents the evolution of integration from discrete projects to continuous operational management, treating integrations with the same rigor, automation, and expertise that DevOps brought to software development and SecOps brought to security. As you evaluate integration solutions for 2026, the question isn't which platform has the most connectors or the lowest price per transaction. The question is whether you want to operate integrations yourself or focus on delivering business value while someone else handles integration operations on your behalf.
