GoWind OA

GoWind OA is an enterprise collaboration and office automation system covering day-to-day office scenarios such as approval workflows, HR attendance, leave requests, and expense reimbursement. The system ships with a lightweight workflow engine as the foundation of its approval flows, together with a web admin console and a mobile app, helping enterprises handle requests, approvals, clock-ins, and expense management on a single platform.

GoWind OA is an open-source project of the GoWind ecosystem, released under the MIT license: the source code is open, and trials, feedback, and contributions are welcome. You are also welcome to reach out through the contact information at the end of this page.

1. Core Highlights

1. Workflow Engine

• Lightweight approval foundation: a built-in lightweight workflow engine serves as the basis for approval flows across the entire system;
• Linear state machine: flows advance linearly through a state machine, keeping node transitions clear and controllable;
• Countersign / or-sign: nodes support countersign (all approvers must pass before the flow moves on) and or-sign (any single approval passes);
• Approval withdrawal: applicants can withdraw a flow that has not yet completed, correcting mistaken submissions in time;
• Visual workflow editor: flows are designed and adjusted visually, lowering the barrier to workflow maintenance.

2. Approval Center

• Centralized to-dos: every approval that needs my action is gathered in one to-do list, cleared one by one with nothing missed;
• Reassignment collaboration: approvers can hand a document over to another colleague, keeping the flow alive even when someone is out of office;
• Full audit trail: submission, approval, rejection, and reassignment of every document are recorded throughout, traceable at any time.

3. Attendance Management

• GPS + Wi-Fi geofence clock-in: mobile clock-in combines GPS positioning with a Wi-Fi geofence for double verification, so locations are genuine and trustworthy;
• Scheduled settlement: attendance data is settled on a fixed cycle, automating monthly statistics and reducing manual verification.

4. Leave Management

• Quota management: leave quotas are managed centrally with clearly visible balances, and over-quota requests are blocked automatically;
• Half-day granularity: leave supports the half-day as the minimum unit, matching real time-off habits.

5. Expense Reimbursement

• Direct invoice photo upload: photograph and upload invoices from the mobile app, submitting reimbursement materials on the spot — no pasting or scanning required;
• Workflow-based approval: reimbursement claims go through the unified approval flow, with progress visible in real time.

6. Four Types of Administrative Documents

• Business trip request: online application and itinerary reporting for business trips;
• Overtime request: overtime registration tied into attendance data;
• Seal usage request: application and registration for company seal usage, with every use on record;
• Outing request: filed outing requests keep whereabouts clear.

7. In-App Messages and Announcements

• SSE real-time push: approval to-dos and flow status changes are pushed to clients in real time via SSE, so nothing is handled late;
• Company announcements: administrators publish company announcements, delivering important notices to the whole company.

8. Corporate Directory

• Clear org structure: browse colleague information along the org chart and find people fast;
• Data masking: sensitive information such as phone numbers is displayed masked, protecting employee privacy.

9. Dynamic Form Engine

• Forms configured with the flow: request forms are rendered by the dynamic form engine, with fields defined flexibly by document type;
• Fast response to business change: adding or adjusting document fields is done through configuration, with no code changes.

4. Use Cases

Taking everyday enterprise approvals online

Move requests scattered across paper forms and group chats onto one online platform:

• Business trip, overtime, seal usage, and outing requests all follow a unified approval flow;
• Flow nodes are designed and adjusted to match your own management rules;
• The approval process is fully recorded, traceable and auditable afterwards.

HR attendance and leave management

Attendance and leave management backed by genuine location data:

• GPS + Wi-Fi geofence clock-in for field and on-site staff, eliminating buddy punching;
• Leave quotas managed centrally, with half-day granularity fitting HR policies;
• Attendance data settled on schedule, with monthly statistics automated.

A closed loop for expense reimbursement

Reimbursement materials circulate electronically, with progress checkable anytime:

• Employees photograph and upload invoices on mobile, submitting reimbursements anytime, anywhere;
• Reimbursement claims enter the unified approval flow, giving finance a solid basis for processing.

5. Tech Stack and Deployment

The backend is built on the go-kratos microservice framework, uses Ent ORM for data access, and stores business data in PostgreSQL; the admin console is built on Vue3 and Element Plus, and the mobile app is developed with Flutter, covering Android and iOS. For local deployment, docker-compose brings up middleware such as PostgreSQL, Redis, MinIO, etcd, and Jaeger with one command; business services are split by client into two entry groups — an admin console BFF and a mobile BFF — each with its own SSE push port.
