Connect Fortnox and Odoo POS

Connecting Fortnox and Odoo POS for a company could allow financial data from point-of-sale transactions to be transferred automatically into accounting and inventory records. This could reduce manual entry, support more accurate reporting, and help ensure that sales, stock, and financial information remain aligned across both systems.

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

Why connect Fortnox and Odoo POS?

A company operating both Fortnox and Odoo POS could benefit from enabling these systems to exchange data, as this could help streamline business processes and improve the accuracy of information across departments. Without such a connection, staff may need to enter the same data into both systems manually, which increases the risk of errors and wastes valuable time. Additionally, records in the two systems could become inconsistent over time, leading to situations where decisions are made based on outdated or incomplete information. For example, sales data, inventory levels, or customer details could diverge between Fortnox and Odoo POS, complicating financial reporting and operational planning. If a connection were established, the types of data that could be exchanged would depend on the business needs and the capabilities of each platform. Commonly, companies look to synchronize sales transactions, inventory updates, customer information, and accounting entries between their accounting or ERP system and their point-of-sale solution. This could help ensure that financial records reflect real-time sales activity and that stock levels are accurate across both systems. Ultimately, what data can actually be exchanged would depend on what 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 Odoo POS 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.
