Smart Tax Planning
AI-Enabled Solutions
Engagement Model: End-to-End Platform Development
Client Industry: FinTech / Tax Technology / SaaS
Executive Overview
A tax-planning technology firm sought to develop a sophisticated, browser-based platform serving accountants, tax advisors, and small business owners. The solution required real-time tax projections, scenario simulations, strategic recommendations, and seamless integrations with leading bookkeeping applications.
Rays Techserv was engaged to architect and build the complete platform leveraging the Microsoft ecosystem (ASP.NET, Azure, SQL Server) to deliver enterprise-grade scalability, security, and performance.
The Challenge
The client faced a multifaceted technical and business challenge:
- Building a robust projection engine capable of modelling personal and business tax scenarios, what-if analyses, and dynamic strategy recommendations
- Establishing secure integrations with external bookkeeping platforms (QuickBooks Online, Xero) for automated financial data synchronization
- Implementing multi-tenant architecture supporting multiple advisors, their clients, role-based permissions, and secure data flows with real-time analytics
- Achieving rapid time-to-market with core modules (projections, strategies, integrations) while maintaining flexibility for iterative enhancement
Solution Approach
Rays Techserv executed a comprehensive full-lifecycle development approach utilizing Microsoft technologies.
Key Deliverables – Core Contributions
- Architecture & Platform Stack: Designed scalable architecture using ASP.NET Core for web UI and API layers, Azure App Services and Azure SQL Database for performance and scalability, with microservices for modular functionality.
