Connect Klarna and Subiekt GT

Connecting Klarna and Subiekt GT for a company could make it possible to automate the transfer of payment and order data between the two systems. This could support more efficient financial reconciliation, reduce manual entry errors, and improve the overall management of transactions and accounting processes.

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

Why connect Klarna and Subiekt GT?

A company that runs both Klarna and Subiekt GT could benefit from connecting these systems to enable data exchange between them. Without such a connection, staff may have to enter the same information into both systems, which increases the risk of errors and consumes valuable time. This manual duplication can also result in records drifting apart, meaning that customer or transaction details in one system may not match those in the other. As a result, decisions could be made based on outdated or inconsistent data, which can negatively affect business operations and customer satisfaction. If Klarna and Subiekt GT were connected, the types of data that could be exchanged would depend on the roles these systems play. Klarna is widely known as a payment service provider, while Subiekt GT is recognized as an invoicing and sales management system. The connection could enable the transfer of payment status, transaction details, customer information, and order references between the systems. This could help ensure that sales records in Subiekt GT are updated promptly when payments are processed through Klarna, and that payment information is accurately reflected in financial records. What can actually be exchanged depends on what each system exposes through its API, and is determined per situation.

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 Klarna and Subiekt GT 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.
