Connect Fortnox and Shopify Plus

Connecting Fortnox and Shopify Plus for a company using both systems could allow automated transfer of sales, inventory, and financial data between the platforms. This could help reduce manual data entry, support more accurate reporting, and improve coordination between accounting and e-commerce operations. Such integration could also streamline order management and stock updates.

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

Why connect Fortnox and Shopify Plus?

A company that operates both Fortnox and Shopify Plus could benefit from connecting these systems to enable data exchange between their financial management and e-commerce operations. Without such a connection, staff may need to manually enter orders, customer details, and inventory updates in both systems, which could result in duplicated work, increased risk of errors, and records that gradually diverge from one another. This lack of synchronization could lead to situations where decisions are based on outdated or incomplete information, particularly regarding sales figures, stock levels, or customer balances. If a connection were established, it could enable the transfer of data such as sales orders, product information, inventory quantities, and customer records between Fortnox and Shopify Plus. This could help ensure that financial records in Fortnox reflect the latest e-commerce transactions from Shopify Plus, and that product and inventory data in the online store remain accurate according to the accounting system. The actual scope of what can be exchanged would depend on the data each system makes available through its API and would need to be determined for each specific 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 Shopify Plus 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.
