Accountable is accounting and tax software for the self-employed and freelancers. Developed by Brussels-based Accountable SA, the platform combines bookkeeping, invoicing, expense management and tax filing.
Accountable was initially available in Belgium and launched in Germany in 2020. In 2025, Norwegian software group Visma acquired a minority stake in Accountable SA.
History Accountable was developed in Brussels by Nicolas Quarré, Alexis Eggermont and Hassan Ayed. The software was available in Belgium by 2018, when the company raised €1.7 million in a funding round led by Connect Ventures.
The company entered the German market in April 2020. It raised €5.7 million in Series A financing in 2021, when it reported more than 10,000 users in Belgium and Germany. Additional investment brought the total Series A financing to €10 million in 2022.
In April 2025, Visma acquired a minority stake in the company. It had about 60,000 users and around 60 employees at the time. Belgium remained its largest source of revenue, while Germany was its faster-growing market.
Software and services Accountable is designed primarily for freelancers, sole traders and other self-employed. Users can connect bank accounts, record receipts and business expenses, create invoices and prepare tax returns.
In February 2026, Accountable added a business bank account to its software in Belgium. In Germany, Accountable introduced an AI-based tax assistant in October 2023.
Legal dispute In late 2025, the Berlin Chamber of Tax Advisers (Steuerberaterkammer Berlin) challenged Accountable’s use of the name KI-Steuerberater (“AI tax adviser”). It argued that the name could violate German rules protecting the title Steuerberater (“tax adviser”). Accountable rejected this argument and said it would contest the case. The case was still pending in September 2026.
