Connect Fortnox and Miva

Connecting Fortnox and Miva for a company could enable the automated exchange of financial and operational data between the two systems. Such an integration could reduce manual data entry, improve the accuracy of records, and support more timely financial reporting by ensuring that relevant information flows efficiently between Fortnox and Miva.

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

Why connect Fortnox and Miva?

A company operating both Fortnox and Miva could benefit from enabling these systems to exchange data, as this could support more efficient business processes and reduce the risk of errors. Without such a connection, staff might need to enter the same information in both systems, which could lead to inconsistencies and wasted effort. For example, if customer or order data is updated in one system but not the other, records could drift apart over time and decisions could be made based on outdated or incomplete information. This situation could undermine confidence in reporting and make it harder to respond quickly to business needs. In practice, the types of data that could be exchanged between systems like Fortnox and Miva include customer records, order details, product information, inventory levels, and financial transactions. The actual data that can be exchanged, and how reliably this can be done, depends on what each system exposes through its API and must be determined for each specific case.

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 Miva 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.
