Connect Fortnox and WordPress

Connecting Fortnox and WordPress for a company could allow financial or customer data to be exchanged between the accounting features of Fortnox and the website or e-commerce functions managed through WordPress. This could support more efficient data handling and the reduction of manual entry between the two platforms.

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

Why connect Fortnox and WordPress?

A company that uses both Fortnox and WordPress could benefit from connecting these systems to enable data exchange between their accounting and web platforms. The main reason for seeking such a connection would be to reduce manual work and ensure that information remains consistent across both environments. Without a connection, staff may need to enter the same data in both systems, which increases the risk of errors, consumes time, and can lead to records diverging over time. For example, customer or product details updated in one system might not be reflected in the other, resulting in outdated or conflicting information being used for business decisions. The types of data that could be exchanged between Fortnox and WordPress depend on the specific business processes in use. Commonly, companies may want to synchronize customer information, order details, product catalogs, or invoice data. This could help ensure that sales made through a WordPress-based online store are accurately reflected in Fortnox for accounting and inventory management purposes. The actual data that can be exchanged depends on what each system makes available through its API and should be determined for each individual 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 WordPress 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.
