FinTrack SaaS Platform
Built a full-stack multi-tenant financial SaaS with real-time dashboards, team management, and Stripe billing — from zero to production in 14 weeks.
Client background
FinTrack Inc. is an early-stage fintech startup based in Singapore, building tools that give SME finance teams real-time visibility into cash flow, burn rate, and runway. Founded in 2023 by two ex-bankers, the team had strong domain expertise but no in-house engineering capacity.
The challenge
The founding team was running their entire operation in Google Sheets, manually copying data from three different bank feeds each morning. As paying customers grew past 30 companies, the process became unsustainable — numbers were wrong, sheets conflicted, and onboarding a new customer took 3 days. They needed a production-grade multi-tenant SaaS, fast.
Discovery & planning
Initial Discovery Call
90-minute video call with both co-founders. We mapped their current workflow end-to-end, identified the 5 biggest pain points, and confirmed the must-have vs nice-to-have features for v1.
Requirements Workshop
2-hour session to define user roles (Admin, Analyst, Viewer), data models, and multi-tenant isolation strategy. We agreed on a PostgreSQL row-level security approach.
Architecture Review
We presented two architecture options: a monorepo Next.js + Express API vs a separate frontend/backend. Client chose the monorepo for faster iteration at their stage.
Project Kickoff
Signed SOW, set up Linear board with 47 user stories across 4 epics, established weekly Friday demos, and handed over Figma access for design sign-off.
Technical solution
We designed and built a fully multi-tenant SaaS platform where each company's data is strictly isolated at the database level using PostgreSQL Row Level Security. The platform includes a real-time dashboard powered by a WebSocket connection, automated bank-feed sync via Plaid, Stripe-integrated subscription billing with usage-based tiers, and a role-based team management system.
