SaaS Application for Tax Compliance

Hi,

I am planning to develop a **web-based SaaS application for Chartered Accountants / Tax Practitioners for Income Tax Notice Management and Compliance**.

The basic concept is:

**Income Tax Portal → Automatic Notice Retrieval → Notice Dashboard → Due Date → Client Documents → Staff Assignment → Reply/Compliance → Filing → Closure**

The software should be similar in concept to a **Notice Board**, but I want to make it more useful from the actual CA-office compliance point of view.

### Key Features Required:

1. CA/Firm login with multiple staff/user access.
2. Add/manage multiple clients and PANs.
3. Integration with Income Tax portal/API/ERI, subject to authorised availability, for automatic notice retrieval.
4. Automatic sync and identification of new notices.
5. Notice-wise details:

* Client/PAN
* AY/FY
* Section
* DIN/Reference
* Notice date
* Response due date
* Notice type
* Status
6. Dashboard showing:

* New notices
* Pending notices
* Due today
* Due within 3/7 days
* Overdue
* Documents pending
* Reply pending
* CA approval pending
* Filed/Closed
7. Powerful search and filters by client, PAN, AY, section, status and due date.
8. Staff-wise assignment and responsibility.
9. Client document request and document upload facility.
10. Automated email/WhatsApp reminders.
11. AI-based notice reading to extract important information and prepare:

* Notice summary
* Issue identified
* Documents/information required
* Suggested next action
12. Notice-wise complete timeline/history.
13. Reply/document upload and CA approval workflow.
14. Filing acknowledgement and closure record.
15. Complete audit trail of who performed which action and when.
16. Reports/MIS and Excel/CSV export.
17. Secure document storage, backup, encryption and role-based access.

### Important Requirement

I do **not** want to build a general accounting or complete tax-practice-management software initially.

The first version should be **strictly focused on Income Tax Notice → Compliance → Closure**.

The system should also be designed in a scalable manner so that additional features can be added later.

### Please provide a quotation

Please give me a detailed quotation separately for:

**A. UI/UX & Frontend**
**B. Backend & Database**
**C. Income Tax API/ERI Integration**
**D. AI Integration**
**E. Client/Document Portal**
**F. WhatsApp/Email Integration**
**G. Security, Backup & Hosting Setup**
**H. Testing & Deployment**
**I. Annual Maintenance/Support**

Please also mention:

* Estimated development time
* Technology stack proposed
* One-time development cost
* Monthly/annual running cost
* API/third-party charges, if any
* Maintenance cost
* Number of users/clients supported in the quoted infrastructure
* Whether source code/IP will belong to us
* Post-development support period

**Important:** Before final development, we need to confirm the feasibility and authorised process for Income Tax notice retrieval through the Department's API/ERI framework. The software architecture should therefore be designed so that the API integration can be added/modified without rebuilding the entire application.

Please review the concept and provide your **technical approach and commercial quotation**.
