What it does:
- Log expenses in under 15 seconds (amount, category, date, receipt)
- Real-time per-person balance calculations
- Automated "Settle Up" calculator that minimizes transactions
- CSV/PDF exports for accounting
- Free for teams up to 3 members
Tech stack:
- Next.js 15 with App Router
- Supabase (Postgres + Auth + Storage)
- Stripe for subscriptions
- AWS SES for emails
- TypeScript throughout
What makes it different:
Most expense trackers are either too simple (spreadsheets) or too complex (enterprise software). I focused on speed—the form is minimal, balances update in real-time, and the UI is mobile-first.
Free tier: Up to 3 team members, unlimited expenses, basic dashboard. No credit card required.
Paid tiers: Features like CSV export, Settle Up calculator, and advanced charts, slack integrations etc.
I'd love feedback from the HN community, especially on: - The balance calculation logic (currently splits equally) - The UX flow for adding expenses - Any features you'd find useful for small teams
