Who this tool is for
Industries
- SMBs wanting one integrated office stack
- Teams standardised on Teams and Outlook
- Service, legal and accounting practices
- Companies needing EU-region data processing
Microsoft 365 bundles Word, Excel, Teams, Outlook and 30+ apps into a single subscription, making it the default productivity suite for most German SMBs. For DACH businesses the key feature is the EU Data Boundary: when enabled, customer data is processed and stored within the EU, which simplifies the GDPR conversation considerably.
Microsoft includes a Data Processing Addendum (DPA) and Standard Contractual Clauses (SCCs) in its Online Services Terms, so an AV-Vertrag is available out of the box. That said, the underlying data residency is classified as EU/US, so some processing and support paths can still involve a US parent company. It fits service firms, retailers, law and accounting practices that want one well-integrated stack rather than stitching tools together.
