Connect Fortnox and Act-on

Connecting Fortnox and Act-on for a company could enable the transfer of relevant financial or customer data between the two platforms. This could support more effective marketing automation by using up-to-date information from accounting or invoicing processes, and could facilitate improved reporting or analysis across business and marketing functions.

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

Why connect Fortnox and Act-on?

A company using both Fortnox and Act-on could consider connecting these systems to enable more efficient and accurate data exchange between their finance and marketing operations. Without such a connection, staff may need to enter customer, sales, and campaign data separately into each platform, increasing the risk of errors and inconsistencies. This manual process can lead to situations where records in one system do not match those in the other, making it difficult to maintain a reliable overview of business performance. Decisions might then be based on outdated or incomplete information, potentially impacting customer experience or financial planning. If a connection were established, it could allow for the transfer of key business data. For example, customer and contact records, sales transactions, and invoice details from Fortnox could be shared with Act-on to support targeted marketing efforts. Conversely, engagement data and marketing responses from Act-on could be sent to Fortnox, giving finance teams better insight into the effectiveness of campaigns and customer interactions. The specific data that can be exchanged depends on the capabilities each system exposes through its API, and must be determined on a case-by-case basis.

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 Act-on 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.
