Connect SAP ECC-R/3 and Klarna

Connecting SAP ECC-R/3 and Klarna for a company could enable the transfer of financial or order-related data between the enterprise resource planning environment and Klarna’s payment platform. This could support more efficient reconciliation, improved visibility into payment status, and streamlined management of transactions involving Klarna within SAP ECC-R/3 processes.

You can build this integration on the System2System platform. We design the connection between SAP ECC-R/3 and Klarna around the way you work — not as an off-the-shelf connector, but to fit your systems.

Why connect SAP ECC-R/3 and Klarna?

A company operating both SAP ECC-R/3 and Klarna could benefit from connecting these two systems to enable more efficient data exchange across finance, order management, and payment processing functions. Without such a connection, staff may need to manually enter the same data—such as customer details, invoice amounts, and payment statuses—into both systems. This manual process can result in duplicated effort, errors, and inconsistencies, with records in one system not matching those in the other. Over time, this drift could mean that decisions are made based on outdated or incomplete information, leading to operational inefficiencies and potential financial discrepancies. If a connection were established, the types of data that could be exchanged between SAP ECC-R/3 and Klarna would depend on what each system is designed to handle and expose. For example, SAP ECC-R/3 is widely known as an enterprise resource planning platform managing core business processes, while Klarna is recognized for payment and checkout solutions. Data that could be exchanged might include order details, payment confirmations, invoice statuses, and customer account information. The actual scope of data exchange would always depend on the capabilities and permissions provided by each system’s API and would need to be defined for each specific implementation.

How System2System builds an integration

Connectors

We connect to each system through the interface it offers — an API, a database, a file exchange or a webhook — and handle authentication, rate limits and retries.

Mapping

Fields rarely line up one to one. We map and transform the data so both systems receive it in the shape they expect.

Workflow

We define what triggers an exchange, in which direction data flows and which system takes precedence when the two disagree.

Monitoring

Every exchange is logged. Failures are flagged and can be replayed, so nothing disappears without anyone noticing.

What can actually be exchanged?

That depends on what SAP ECC-R/3 and Klarna make available through their APIs, on the licences and modules in use, and on the version each system runs. Which records are synchronised, in which direction and how often, is something we determine together before any work starts.

We are happy to look at your specific situation and tell you what is feasible — including when the answer is that it is not.
