Connect Fortnox and Shopware

Connecting Fortnox and Shopware for a company that uses both could enable the transfer of financial and order data between the two systems. Such a connection could support more efficient bookkeeping, automated invoice creation, and improved tracking of sales transactions, reducing the need for manual data entry and minimizing the risk of errors.

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

Why connect Fortnox and Shopware?

A company that uses both Fortnox and Shopware could benefit from enabling these systems to exchange data. Without a connection between them, staff may need to enter the same information, such as customer details or order data, in both systems separately. This increases the risk of errors, inconsistencies, and delays, as records can become out of sync and decisions may be made based on outdated figures. For example, if product stock levels or order statuses are not updated across both platforms, sales or accounting teams could be working with incomplete or conflicting information. Common types of data that could be exchanged between systems of these kinds include product information, inventory levels, customer records, order details, and financial transactions. The specific data that can actually be exchanged depends on what each system exposes through its API and would need to be determined for each 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 Fortnox and Shopware 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.
