Microsoft 365 Business
Microsoft 365 Business is a comprehensive productivity suite for organisations: desktop and online Office apps (Word, Excel, PowerPoint), the Teams collaboration platform, Exchange email, and 1 TB OneDrive storage per user. Distributed by Dzo with a genuine VAT invoice (hoá đơn đỏ) and a Vietnamese-speaking implementation team. Ideal for businesses conducting a licence audit or upgrading from unlicensed Office to a compliant platform.
Overview
Microsoft 365 Business is a SaaS suite that combines Microsoft's classic productivity apps with enterprise-grade cloud security. Unlike older perpetual licences (Office 2019/2021), Microsoft 365 Business receives continuous updates and includes collaboration, security, and device management services.
With a per-user subscription model, businesses pay only for the headcount actually using the software — scale up or down each billing cycle without being locked to specific hardware or software versions. Each user may install on up to 5 PCs, 5 mobile phones, and 5 tablets.
Microsoft 365 Business comes in three tiers: Business Basic (cloud-only), Business Standard (full desktop apps plus Webinar), and Business Premium (adds advanced security, Azure AD P1, and Intune). Organisations can mix tiers across different staff groups within the same tenant.
This is the most frequently audited software in the 2026 licence review wave, owing to the widespread use of unlicensed Office in Vietnam. Holding a valid Microsoft 365 Business licence is the first and most essential step toward full software compliance.

Frequently asked questions
What is the difference between Microsoft 365 Business and Microsoft 365 Apps?
Microsoft 365 Business includes both desktop apps (Word, Excel, PowerPoint) and full cloud services (Exchange email, Teams, SharePoint, OneDrive). Microsoft 365 Apps includes only the installed desktop apps — no business email or cloud collaboration services.

Yes. Dzo issues a valid electronic VAT invoice under Decree 123/2020 and accepts VND payment via business bank transfer — no foreign-currency card required.
Where is my data stored?
For tenants registered in the Southeast Asia region, data is stored primarily in Singapore and Hong Kong. If your organisation requires data residency in Vietnam, Dzo can advise on a suitable hybrid solution.
