Tetra eOffice
A unified digital workplace: documents, workflows, HR, digital signing and every app your organization uses, brought into one place — running on your own infrastructure.
For you whenWhen you need one place for documents, workflows and approvals.
One platform, the whole office
One app per department, one Excel file per process, one email per approval. Tetra eOffice brings it all into one place: one sign-in, one flow of work, one source of data — so people work together instead of jumping between disconnected systems.
Every office function, built into the platform
Use each part on its own or combine them all — they share the same permissions, workflows and data.
Administrative documents
Inbound/outbound documents per Decree 30/2020, auto-numbering, interoperability.
Document management
Central storage, automatic OCR and natural-language search.
Workflows (BPM)
Drag-and-drop process design, flexible approvals, progress tracking.
HR management (HRMS)
Attendance, leave, payroll, social insurance — compliant with Vietnamese law.
Digital signing
Vietnam-standard digital signatures (VNPT, Viettel, MobiFone, FPT CA), internal signing.
Tendering & procurement
Procurement workflows, bid documents, evaluation and approval.
Tasks & collaboration
Assign work, reminders and centralized notifications across the organization.
AI assistant
Ask questions over your documents, scoped to each user's permissions.
Connect every app — today and tomorrow
eOffice doesn't replace what already works — it connects it. Open APIs (REST, OpenAPI, Webhooks) plug in ERP, CRM and data systems. Already on Microsoft 365? eOffice reuses the sign-in (Entra ID) and storage (SharePoint) you already have. Each new app is just another tile in the same digital office.
Open API
REST, OpenAPI and Webhooks — every feature is integrable.
Leverage Microsoft 365
Reuse Entra ID sign-in and SharePoint storage if your organization has them.
Connect existing systems
ERP, CRM and data platforms (Power BI, Snowflake, Kafka...).
Sovereign on your own infrastructure
eOffice runs on your own infrastructure — your business data stays inside the organization. Already on Microsoft 365? Reuse it (Entra ID sign-in, SharePoint storage). Not on M365? Run independently with an open-source stack (Authentik, MinIO). You choose where your data lives — no vendor lock-in.
- Deploy on-premise or in the cloud
- Vietnam compliance out of the box (Decree 30, Labor Code 2019, social insurance)
- Data sovereignty — your data is yours
