Joiin, the financial reporting and consolidation platform, has announced an integration with Fortnox, one of Sweden's leading business platforms and a core part of the country's small-business software landscape, bringing single and multi-entity reporting capabilities to businesses that rely on the Swedish software.

The launch marks a significant step in Joiin's continued international expansion and addresses a growing challenge for multi-entity organisations: producing consistent reports when different entities operate on different accounting systems.

As companies grow, acquire businesses or expand across borders, finance teams seldom have every entity on the same platform. A Swedish subsidiary may run on Fortnox, while a UK parent uses Xero and US entities rely on QuickBooks Online. The result is often a patchwork of ledgers, currencies and charts of accounts that must be brought together manually before group reporting can begin. With the new integration, these sources can now be brought into one reporting environment.

Finance teams and accountants can connect one or multiple Fortnox organisations to Joiin and build reports, dashboards and KPIs directly from their financial data. For groups, Fortnox entities can be consolidated alongside companies using other accounting platforms and spreadsheets, creating a single view of financial performance across the entire organisation.

Joiin handles much of the underlying complexity behind the scenes, including chart of accounts mapping, multi-currency reporting, intercompany eliminations — which remove transactions between group entities so they are not counted twice — and consolidation. A Swedish entity reporting in SEK, the Swedish krona, can therefore sit within a wider international group and be reported in the group's chosen currency without relying on spreadsheet exports and manual roll-ups.

Beyond standard accounting reports, the platform enables businesses to create fully customised profit and loss statements, balance sheets and cash flow reports, interactive dashboards and professional, board-ready report packs. Finance teams can combine financial and non-financial data, analyse performance, track budgets against actuals and gain deeper insights to support better decision-making.

Fortnox users can also take advantage of Joiin Intelligence, which brings AI-powered insights and automation into their financial reporting. From asking questions about financial data and generating report commentary to building reports, mapping charts of accounts and identifying potential intercompany eliminations, Joiin's AI agents are designed to reduce manual work, simplify complex tasks and streamline month-end reporting.

Extending these capabilities beyond the Joiin platform, the company's MCP Server now supports any MCP-compatible AI application, including Claude, ChatGPT, Microsoft Copilot, Cursor and Dust. MCP, or Model Context Protocol, is an open standard that allows AI applications to connect to external data sources and tools. This enables businesses to securely connect their Fortnox financial data with their preferred AI tools, opening up new opportunities for financial analysis, automated workflows and deeper insights.

Lucien Wynn, CEO and Co-Founder of Joiin, said: “Fortnox is a cornerstone of the Swedish business ecosystem, and this integration marks a significant step in Joiin's international growth strategy.

“As businesses expand across borders, they increasingly operate across multiple currencies, entities and accounting platforms. Our focus is on removing that complexity and giving finance teams a single, connected view of financial performance, regardless of which accounting systems they use.

“This integration strengthens our multi-platform capabilities while opening up the Swedish market to Joiin. It's an opportunity to support both growing international groups and Swedish businesses and accounting firms looking for more advanced financial reporting, consolidation and AI-powered insights.”

Joiin is designed to work across accounting platforms rather than requiring businesses to standardise their finance systems before they can consolidate — an approach common among modern reporting and consolidation tools, which typically sit on top of the systems businesses already use. Fortnox joins the company's growing ecosystem of accounting and financial data integrations, which already spans platforms such as Xero and QuickBooks Online alongside spreadsheet data, enabling finance teams to combine data from different sources into a consistent reporting structure.

This capability is particularly valuable for international groups, acquisitive businesses, private equity portfolios and accounting firms managing clients across different accounting systems. Users can map different charts of accounts into a common group structure, consolidate entities, manage currency differences and create consistent reporting across the organisation, while individual businesses continue using the accounting software that works for them.

How the Fortnox integration works

Users add a company in Joiin, select Fortnox and authenticate using their existing Fortnox account. Once connected, financial data is brought into Joiin and automatically refreshed every 24 hours, with a manual refresh available whenever required. Multiple Fortnox organisations can also be connected, making it straightforward to report across larger groups or multiple clients.
