Diamant/4 - 2026 Pricing, Features, Reviews & Alternatives

Diamant/4 is the modular accounting and controlling software from Diamant Software. Since 1980, Diamant Software has focused exclusively on accounting and controlling. Today, this expertise is the foundation for Agentic Finance & Controlling: Diamant develops agents that take over routine tasks, prepare bookings and analyses, and document every step in a traceable way. The agent handles the routine. People make the decisions.

Diamant/4 is designed for mid-sized companies in all industries and for organisations in the health and social care sector that work with complex financial structures, for example multiple legal entities, intercompany processes or consolidated financial statements. Typical users are accounting leaders, CFOs and commercial directors, as well as controlling and finance teams.

Financial Accounting is the base module. Depending on your requirements, you can add Cost and Performance Accounting, Fixed Asset Accounting, Incoming Invoice Management, Invoicing, Banking, Planning, Analysis and Reporting, Group Accounting and Integration. Despite its broad functionality, the software remains simple and clear to use, and it grows with your organisation.

Diamant/4 is ERP-independent: it doesn’t replace your existing systems, it complements them. Through the Diamant Integration Hub, the Microsoft Excel integration and the Diamant BI integration, it fits into existing ERP, DMS, BI and CRM landscapes.

Diamant/4 runs as Diamant Cloud on Microsoft Azure. Data is stored in certified data centres in the EU. Certifications and attestations: ISO 27001:2022, BSI C5 and ISAE 3402. Diamant/4 supports GoBD requirements. More than 350 employees support 100,000 users in Germany, Austria and Switzerland. Get to know Diamant/4 in the demo video or book a free product consultation.
