SAP rarely lives on its own. There is always a CRM nearby, analytics, warehouse tools, payment services, portals, plus a few internal systems nobody wants to touch. And that is where things get real: data has to move reliably, processes should survive releases, and failures must be visible instead of quietly piling up. In plain terms, SAP Integration becomes a daily necessity.

The outlook for this space is pretty clear. More hybrid landscapes, more API-first work, more event-driven scenarios, more automation wrapped around SAP processes. And, oddly enough, more control too: security, permissions, audit trails, stability, long-term supportability

That is why picking a vendor is not a checkbox exercise. The details matter: integration design, mapping rules, error handling, end-to-end testing, and what happens after go-live. This article reviews some of the best companies in the SAP integration companies segment, each with a different angle and delivery style

 

1. OSKI Solutions

At OSKI Solutions, we build custom software and web systems for teams that are trying to modernize operations and keep scaling without the platform turning into a patchwork. A lot of the work lives in the middle layer: APIs, data flows, and the boring but critical rules that decide whether systems stay in sync. This is where OSKI Solutions provides SAP Integration services, connecting SAP with the apps that run day-to-day work like storefronts, customer tools, warehouse systems, finance platforms, and internal portals. Some integrations are neat and predictable. 

The technical approach usually depends on what the landscape already looks like. We often combine .NET and Node.js backends with cloud services on Azure or AWS, then add containerized delivery and CI/CD so integrations do not get “hand-deployed” forever. SAP endpoints might be exposed through APIs, or handled through queued and event-driven patterns when reliability matters more than speed. Short line. No magic. Just consistent integration design, careful mapping, and clear error handling so people can actually support it later.

Key Highlights: 

• Custom software delivery built around integration-heavy roadmaps
• SAP connections designed for mixed stacks, including CRM, ERP add-ons, and payment services
• Cloud-first integration patterns using Azure or AWS with DevOps practices
• Focus on maintainable interfaces with mapping rules, logging, and controlled access

Services: 

• SAP Integration for connecting SAP with external applications and internal web systems
• Custom API development for SAP-adjacent services and integration layers
• Third-party integrations linked to business flows, including CRM and payment gateways
• Cloud migration work that keeps SAP-related interfaces stable during change
• Integration testing, monitoring setup, and incident-oriented troubleshooting
• Dedicated teams for ongoing integration delivery, refactoring, and support

2. Elinext

Elinext delivers SAP-focused engineering where integration work sits at the center of the job. A lot of it is about making SAP talk to the rest of the landscape without turning every change into a small crisis. SAP BTP is used as a practical base for integration build-outs, including interface design, mapping, and the routines around keeping integrations stable once they are live. Some engagements lean into Integration Suite style work, like building integration flows, setting up API-based connectivity, and wiring SAP processes to external applications that refuse to behave the same way twice. It is fairly hands-on work. And yes, the unglamorous part matters.

Standout qualities:

• SAP BTP used for integration build and extension scenarios
• Interface work that connects SAP processes with external applications
• Attention to mapping, data movement, and integration reliability

Services include:

• SAP BTP integration design and implementation
• Integration flow development and interface mapping
• API management setup for SAP connectivity scenarios
• Integration monitoring support and interface troubleshooting

3. Accenture

Accenture approaches SAP integration as part of broader enterprise programs where SAP is one system among many, not a standalone island. Integration work often uses SAP BTP services to connect SAP applications, cloud tools, and older platforms that still run critical workflows. That includes building and maintaining integration flows, setting up API management, and working with connector-style approaches when direct integration is not realistic. 

Another aspect is the operational side: testing end-to-end flows, diagnosing interface failures, and keeping integrations working through releases and cutovers. A lot of attention goes into process integration, not just moving data from A to B. Short message, long impact. Small mismatches in master data or error handling tend to show up fast.

What they do well:

• SAP BTP Integration Suite used for building interfaces and integration flows
• API management and connector-driven connectivity for mixed landscapes
• End-to-end testing and troubleshooting around integration scenarios

Core offerings:

• SAP Integration Suite flow development and configuration
• API-led integration patterns for SAP and third-party applications
• Connector setup and integration content adaptation
• Integration testing, monitoring, and incident support

4. Deloitte

Deloitte’s SAP work often includes integration as the piece that holds multi-system programs together. It is less about a single interface and more about shaping an integration landscape that stays understandable a year later. Integration design tends to cover architecture choices, interface standards, and the rhythm of releases. It is methodical. Sometimes a bit strict.

SAP BTP appears as a common platform for building and running integrations, especially when organizations want a cleaner ERP core and fewer custom connections sitting in awkward places. That can mean reusable integration patterns, microservice-style components, and governance so integrations do not grow wild. Not every client loves governance. But it prevents surprises.

There is also work around compliance-heavy connectivity, like integration accelerators for invoicing or standardized links between ERP processes and external networks. These efforts usually focus on predictable data movement, audit-friendly flows, and controlled change management. The details are rarely exciting. Still, they tend to decide whether a rollout is calm or chaotic.

Why people choose them:

• Integration architecture tied closely to SAP program delivery and operating model needs
• SAP BTP used for integration build, extensions, and structured connectivity patterns
• Focus on standardization, governance, and long-term maintainability
• Experience with compliance-oriented integrations and controlled rollout support

Their services include:

• SAP integration architecture and interface landscape planning
• SAP BTP-based integration build and modernization work
• Accelerator-style integration approaches for specific business processes
• Integration governance, testing support, and cutover readiness work

5. Capgemini

Capgemini is known for large-scale SAP work where integration is treated as a real discipline, not a side task that gets patched at the end. A typical engagement involves connecting SAP applications with cloud services, legacy tools, and data platforms, then keeping those connections readable and supportable. Short sentence. Big deal. SAP BTP often sits in the middle of the setup, with Integration Suite-style components used for building integration flows, shaping APIs, and handling event-driven messaging where synchronous calls are not enough. Integration governance also shows up early, because one poorly defined interface can turn the next release into a guessing game.

Key points:

• SAP BTP used as an integration layer alongside core SAP systems
• API-led connectivity patterns applied across SAP and external applications
• Event-driven and message-based integration used where real-time syncing is needed
• Integration governance and interface lifecycle practices built into delivery

Services cover:

• SAP BTP integration design and build for hybrid landscapes
• Integration flow development and adapter-based connectivity
• API management configuration for secure system-to-system exchange
• Event and message integration patterns for SAP-connected processes
• Integration testing and operational troubleshooting for interfaces

6. Tietoevry

Tietoevry supports SAP programs where integration work is woven into the platform story, especially around cloud transitions and structured roadmaps. The integration side tends to mix practical interface engineering with platform choices, so SAP systems can exchange data with other enterprise applications without constant manual fixes. A lot of the heavy lifting lands on SAP BTP services, including building integration flows and setting rules around access, error handling, and retries. Small detail: those retries save weekends.

Another part of the portfolio leans into SAP platform operations and adjacent services that still touch integration every day, like archiving, data lifecycle management, and keeping information consistent across connected systems. Integration is not only about shipping messages, it is also about keeping data usable over time, even when applications get replaced or merged. Teams working with BTP commonly use CPI-style integration flow approaches plus API management for controlled exposure of SAP data to other tools. And if the landscape is messy, the work gets structured first - integration inventory, dependency mapping, then the rebuild.

Standout qualities:

• SAP BTP skills that include cloud integration flows and API management
• Work spans SAP platform operations plus integration with surrounding applications
• Attention to data lifecycle topics that affect long-running integrations

Their focus areas:

• SAP BTP-based integration flow implementation and maintenance
• API management setup for controlled access to SAP services
• Interface mapping and data transformation for SAP-to-third-party exchange
• Integration monitoring, incident handling, and stabilization work
• SAP platform administration support aligned with cloud ERP operations

7. T-Systems

T-Systems runs SAP work with a noticeable emphasis on operations and integration stability. Not flashy. Useful. Integration is often treated as part of the target architecture, especially when SAP applications need to coexist with non-SAP systems during migration and modernization.

A common pattern is using SAP BTP capabilities to connect workloads across cloud and hybrid environments, so SAP processes can interact with external applications without hardwired, brittle point-to-point links. The work can include cloud-to-cloud connectivity, integration design for event-driven flows, and the kind of guardrails that keep interfaces from drifting over time. Some projects also pull in automation and DevOps habits, because integration failures usually show up at 2 a.m., not during a planning meeting.

On the managed services side, SAP application management and modernization typically includes governance and tooling that covers SAP and the non-SAP applications that complement it. That matters for integration because the “other system” is often the one that changes first. Integration monitoring, change control, and cutover coordination become part of the delivery rhythm. The result is usually a landscape where integrations are documented, observable, and easier to adjust when business processes shift.

Why people choose them:

• Operational focus that treats interface stability as part of SAP delivery
• SAP BTP used for integration, automation, and controlled connectivity patterns
• Governance and tooling applied to SAP and connected non-SAP applications
• Attention to monitoring and change processes that reduce integration surprises

What they offer:

• SAP integration architecture and interface landscape planning
• SAP BTP-based connectivity for cloud, hybrid, and cross-platform scenarios
• Integration monitoring setup and incident response support for interfaces
• SAP application management that includes integration-aware governance
• Migration support where interface redesign and downtime planning are included

8. Frends

Frends is a low-code integration platform that is often used as the glue between SAP and everything around it. The SAP side is handled through certified connectors, so common integration tasks do not start from scratch each time. Less manual wiring. The platform supports both classic SAP integration styles like IDoc-based messaging and more modern REST API patterns, which helps when an SAP landscape has a mix of old and new interfaces. Process visibility is treated as a first-class thing, with tooling that helps track SAP-related flows and spot where a process stalls or errors out. It also covers workflow automation and API management in the same environment, so SAP integrations can be built, exposed, and operated without splitting the work across too many tools. 

What makes them stand out:

• Certified SAP connectors aimed at reducing custom integration effort
• Support for SAP integration through IDocs and REST-style APIs
• Process visibility tooling for SAP-related flows and exceptions
• Low-code approach for building and maintaining integration logic

Services include:

• SAP connector-based integrations for cloud and on-premises SAP systems
• IDoc-driven message flows and interface orchestration
• REST API enablement for SAP-connected applications
• API publishing and governance for SAP-facing services
• Monitoring and troubleshooting for SAP integration processes

9. Softweb Solutions

Softweb Solutions works as a system integrator with a broad delivery mix, and integration shows up repeatedly across that portfolio. For SAP environments, the work commonly centers on connecting ERP data and processes to surrounding platforms, using APIs, database connections, and secure file transfers rather than brittle one-off scripts. Short sentence. Real impact. A lot of projects lean on Azure-native integration building blocks, which makes sense when SAP needs to talk to cloud apps, analytics layers, or internal services on a schedule or by event.

Automation is another practical angle, because SAP integrations rarely live alone; there is usually a workflow attached to them, plus error handling, retries, and access control. Integration work can also be paired with cloud consulting and modernization activities, so the interface layer evolves alongside the application landscape. Some delivery tracks use established middleware patterns like API-led integration, which helps keep SAP endpoints consistent even when upstream systems change. It is the unglamorous part of IT, but it is also the part that keeps the lights on. 

Why they’re worth a look:

• System integration focus across cloud apps, data, and enterprise platforms
• Patterns for connecting SAP with external systems using APIs and secure transfers
• Azure integration services used for orchestration, messaging, and API control

Their focus areas:

• SAP-to-CRM integrations using APIs and middleware patterns
• Azure Logic Apps workflows for SAP-adjacent process orchestration
• Azure Service Bus messaging for SAP-connected events and queues
• API Management setup for controlled access to SAP-related services
• Integration stabilization, monitoring, and interface troubleshooting

10. Microsoft Azure

Microsoft Azure is a cloud platform, but it also functions as an integration layer for SAP-heavy environments that have to communicate with everything else. The integration portfolio groups services for orchestrating workflows, managing APIs, and handling messaging, so SAP processes can be stitched into broader enterprise flows without turning into a maze. Lots of moving parts. In practice, architects mix orchestration with messaging and API governance, depending on whether the scenario needs near real-time events, scheduled syncs, or tightly controlled service exposure. 

For SAP connectivity, Azure Logic Apps provides an SAP connector that can be used to build automated workflows triggered by SAP events or by activity in other systems. Those workflows can read from or write to SAP, and they can also fan data out to downstream services such as queues, notifications, or data pipelines. Sometimes a gateway is part of the picture for outbound calls into on-premises SAP environments. Sometimes it is not. 

Azure also positions SAP workload support alongside integration scenarios, which matters because integration and hosting decisions tend to collide on the same roadmap. Teams often combine API Management, Logic Apps, messaging, and event routing to keep SAP interfaces stable while external applications change around them. Another common thread is hybrid integration, where a portion of the landscape stays on-premises while cloud services handle orchestration, monitoring, or event distribution. It is a pragmatic setup, not a theoretical one. 

Standout qualities:

• Integration services portfolio covering workflow orchestration, APIs, and messaging
• SAP connector support in Logic Apps for workflow-based SAP interactions
• Hybrid connectivity options for SAP and non-SAP environments

Core offerings:

• Workflow orchestration with Logic Apps for SAP-triggered and cross-system processes
• SAP connector configuration and operations for reading and writing SAP data
• API Management for securing and exposing SAP-related APIs
• Service Bus messaging for SAP-connected queues and asynchronous patterns
• Event Grid routing for event-based integration and downstream automation

11. SAP

SAP builds enterprise software, and the integration layer is a big part of how that software actually works in real organizations. Not everything lives inside one suite, so SAP integration often means connecting ERP processes to CRM tools, procurement networks, data platforms, and plenty of custom apps sitting off to the side. SAP BTP typically plays the role of the hub here, with tools for building integration flows, exposing and protecting APIs, and moving messages between systems when “just call the endpoint” is not enough. Some setups lean on prebuilt integration content to speed up common connections, while others are more bespoke, especially around complex master data or tricky event timing. It is less about one interface. More about keeping the whole landscape predictable.

Highlights:

• Integration capabilities tied to SAP BTP services and packaged integration content
• Support for API management, event-driven messaging, and workflow-style orchestration
• Approaches for connecting SAP applications with third-party platforms and custom services

What they offer:

• Integration flow design and build for SAP and non-SAP applications
• API exposure, security policies, and traffic governance for SAP-related services
• Message-based integration for asynchronous SAP process coordination
• Connector-based connectivity for common enterprise platforms
• Integration monitoring, alerting, and exception handling setup

• Address: Dietmar-Hopp-Allee 16, 69190 Walldorf, Germany
• Phone: +1-800-872-1727

 

12. UiPath

UiPath focuses on automation, and SAP integration shows up in a slightly different way here. The emphasis is often on connecting SAP steps into end-to-end workflows, including processes that still depend on older interfaces or mixed UI and API interactions. Sometimes it is clean and API-driven. Sometimes it is not, and bots fill the gap while teams modernize the plumbing.

In SAP-heavy operations, automation usually touches routine work like invoice handling, order updates, or master data maintenance, where the same screens and transactions repeat all day. Small sentence. Big savings in attention. UiPath also supports integration patterns where workflows pull data from SAP, enrich it with other sources, then push updates back with checks and approvals. That last part matters, because uncontrolled automation can get messy fast.

Strengths:

• Automation-first approach that can connect SAP tasks with wider business workflows
• Support for SAP-related connectors and activities alongside UI automation options
• Orchestration, scheduling, and governance features for SAP process automations
• Process visibility and exception handling built into automated SAP flows

Services cover:

• SAP process automation design and implementation
• Workflow orchestration that coordinates SAP actions with external systems
• Connector-based integration for SAP data exchange and task execution
• Automation governance, monitoring, and exception management for SAP scenarios
• Testing and stabilization for SAP automations during releases and changes

13. Domo

Domo is centered on analytics and operational reporting, so SAP integration is usually about getting SAP data into a shape that people can actually use. That can include pulling transactional and master data, blending it with non-SAP sources, and keeping refresh schedules consistent. Simple on paper. Hard in practice. The platform typically relies on connectors, data transformation steps, and API-style access to keep pipelines moving.

A common pattern is building a semantic layer or curated datasets that mirror how finance, supply chain, or sales teams talk about the business, not how tables are named in the source system. This is where SAP integration becomes more than extraction. It becomes translation. And if something breaks, it needs to be visible quickly, because dashboards do not wait politely.

For SAP-connected analytics, governance and access control tend to matter as much as the charts. Data has owners. Permissions exist. Domo’s work in these environments often includes setting up roles, controlling distribution, and keeping metrics consistent across teams so one department is not quietly using a different definition of “margin” than another. It sounds boring. It prevents arguments.

Why they stand out:

• Analytics-led integration approach that treats SAP data as a living operational source
• Connector and API options for bringing SAP datasets into unified reporting models
• Emphasis on data preparation, blending, and refresh management for SAP pipelines
• Governance features that support controlled access to SAP-derived metrics

Core offerings:

• SAP data ingestion and connector-based extraction into analytics pipelines
• Data transformation and blending for SAP and non-SAP sources
• Dataset modeling to support consistent reporting on SAP processes
• Role-based access and distribution controls for SAP-derived dashboards
• Monitoring and troubleshooting support for scheduled SAP data refreshes

14. Sigmoid

Sigmoid works in data engineering and analytics, with a lot of attention on data integration and the plumbing that makes enterprise reporting usable. In SAP-heavy environments, that usually translates into pulling ERP data into a cleaner layer, then shaping it so downstream tools can trust it. Sometimes it is straightforward ETL. Sometimes it is CDC, replication, or a mix of both, because business teams want fresh numbers, not yesterday’s snapshot. The integration work tends to include mapping, transformation rules, and guardrails around data quality, since SAP data can be surprisingly opinionated once it leaves the source. Quiet work. But important.

Standout qualities:

• Strong focus on data integration methods like ETL, replication, and CDC
• Integration design that supports analytics-ready views of ERP datasets
• Data engineering orientation that blends pipelines, transformation, and quality checks
• Comfort with modern data platforms used as landing zones for SAP-sourced data

Services cover:

• SAP data ingestion into data warehouses and lakehouse-style platforms
• ETL and CDC pipelines for SAP tables and transactional feeds
• Data transformation and semantic modeling for SAP-aligned reporting
• Integration monitoring and pipeline reliability support
• Data governance setup for SAP-driven datasets and access patterns

15. DICEUS

DICEUS operates as a system integration and custom software provider, so integration is not a side note, it is part of the core work. SAP integration shows up both in classic ERP connectivity and in practical situations where SAP has to exchange data with external apps, portals, or logistics tools. A common thread is getting interfaces stable: documenting what exists, cleaning up how data moves, then modernizing the integration layer so it is easier to run. Sometimes the work starts with an audit or troubleshooting phase, because broken interfaces tend to hide in plain sight.

Another angle is ERP integration planning, where SAP is treated as the backbone but not the only system that matters. That can mean choosing integration methods, defining how master data is synchronized, and deciding where APIs make sense versus message-based patterns. Not everything needs to be real time. But some things do.

A lot of SAP integration effort is also about the surrounding ecosystem: EDI-style exchanges, web interfaces, and the small operational routines that keep interfaces from failing silently. If an SAP interface stops updating, the business usually finds out late. So monitoring and error handling end up being part of the integration scope, even when nobody asks for it directly.

What they do well:

• System integration focus that includes SAP ERP connectivity and interface stabilization
• Experience with SAP Process Integration style scenarios and interface troubleshooting
• Approach that blends audit work, documentation, and integration modernization

Core offerings:

• SAP ERP integration assessment and interface cleanup planning
• SAP PI-related integration improvements for EDI and web interface scenarios
• API-based connectivity between SAP and external applications
• Data interchange mapping and transformation for SAP-linked flows
• Integration monitoring setup and incident-oriented troubleshooting

Conclusion

SAP integrations will keep getting more complex - not because anyone is chasing complexity, but because there are more services around, more cloud, more data, more “quick” initiatives. In that reality, the winning approach is usually the most controllable one: clear interfaces, sensible mapping rules, observability, and disciplined change management. 

This article covers some of the best companies in the SAP integration companies segment. Their strengths differ - platform integration, automation, data and analytics, operations. The goal is the same: pick a partner that matches the actual landscape and the day-to-day load.
