Billbase
Personal Finance & Bill Tracking App · 2026
Excel is powerful but it was never designed for personal finance tracking. Formulas break, sheets get messy, and there is no real-time visibility into what is due, what is overdue, or where your money is going. Meanwhile, enterprise finance tools are overkill — too complex, too expensive, and built for accountants, not everyday people.
Building a focused, intuitive finance tracking app that replaces the spreadsheet entirely. Every bill, subscription, and recurring expense gets a digital record with due dates, amounts, categories, and status tracking — all in one clean dashboard. No formulas, no formatting, no manual calculations. Just clear visibility into your financial picture.
A personal SaaS project born from a simple truth — most people are still tracking their finances in Excel spreadsheets, sticky notes, or worse, from memory. Billbase is the modern replacement: a clean, digital-first way to stay on top of your bills, subscriptions, and financial commitments without the friction of a spreadsheet.
Finance apps intimidate people. The design challenge was making Billbase feel less like accounting software and more like a personal assistant — clean, clear, and reassuring. Every UI decision was made to reduce friction, not add to it.
When a bill is marked paid, the dashboard totals and status indicators need to update immediately. Rather than polling or complex webhook systems, Supabase Realtime subscriptions deliver live updates the moment the database changes — zero additional infrastructure required.
Personal finance data demands strict privacy. PostgreSQL Row Level Security policies ensure at the database level that no user can ever access another user's records — even if a query is misconfigured. Security is enforced at the lowest possible layer, not just at the application level.
Next.js App Router handles routing and server-side data fetching for fast initial loads. Supabase provides the full backend stack — PostgreSQL for relational finance data modeling, built-in auth for secure user accounts, Row Level Security for data isolation, and Realtime subscriptions for live dashboard updates. TypeScript throughout with strict mode. No ORM — raw SQL queries for precise control over performance and data shape.
