Visma: Horizon

Yet, Visma had a secret weapon: private equity. Backed by Hg and later CVC Capital, Visma could outspend Horizon on R&D and acquisitions. When Horizon faltered in mobile user experience, Visma bought the best mobile-first startup in the region. When Horizon struggled with e-invoicing standards, Visma simply acquired the company that wrote the standard.

Today, the lines have blurred. Horizon has been largely subsumed into broader groups (with parts sold to Visma’s allies), while Visma has finally unified its core data model under “Visma.net.” The essay’s verdict is this: Horizon won the product war—its architecture was cleaner, its APIs more robust. But Visma won the market war—its understanding of local trust, distribution, and financial engineering proved unbeatable.

The true battleground was not the software, but the accountant. Visma understood that in Europe, the accountant is the ultimate decision-maker for SME software. By acquiring accounting firms themselves (a controversial move), Visma locked in users. Horizon, sticking to a pure software vendor model, relied on partner channels. During the COVID-19 pandemic, when governments needed rapid payroll loan processing, Visma’s owned accounting firms could pivot overnight. Horizon, reliant on independent partners, suffered a two-month lag.

To understand the dichotomy, one must look at the founders’ DNA. Visma, founded in Norway in 1996, grew from a traditional consulting firm into a private equity darling. Its modus operandi was simple yet ruthless: acquire hundreds of local accounting and payroll firms, standardize their backends, but retain their local branding. Horizon, on the other hand, emerged from the Dutch software scene, focusing on building a unified ERP (Enterprise Resource Planning) suite that could scale from the sole trader to the mid-market. Where Visma saw fragmentation as a feature, Horizon saw it as a bug.

Conversely, Horizon focused on building a single, cohesive cloud platform. By unifying CRM, inventory, and accounting into one interface, Horizon offered seamless real-time data that Visma’s patchwork quilt could not initially match. For the digitally native SME, Horizon’s offering was superior. But Horizon struggled with localization; its software often felt like a Dutch product exported to Sweden, rather than a native Swedish solution.

In the annals of European enterprise software, few rivalries have been as consequential—or as complementary—as that between Norway’s Visma and the Anglo-Dutch entity Horizon (formerly known as Exact and its associated brands). While neither is a household name like Salesforce or SAP, their battle for control of the small-to-medium enterprise (SME) accounting space has fundamentally altered how Northern Europe does business. The story of Horizon and Visma is not merely one of competition; it is a masterclass in two divergent strategies: Visma’s aggressive, debt-fueled roll-up of vertical software houses versus Horizon’s product-centric, platform-integration approach.

The watershed moment arrived with the EU’s Open Banking directives (PSD2) and the forced shift to cloud compliance. Visma’s fragmented model initially struggled with API standardization—getting a payroll app in Oslo to talk to an inventory app in Copenhagen was a nightmare. Horizon, with its monolithic cloud architecture, sailed through this transition, offering bank feeds and automated reconciliation years ahead of its rival.
