Most "free" invoicing apps cap you at 3 invoices or hide email delivery behind a paywall. Clever Tally's free tier includes unlimited invoices, email delivery, online payments via Stripe, automated reminders, recurring invoices, and custom brand colors — up to 5 clients. Pro ($7.99/mo) just removes the client limit. That's it. Built solo with Node.js, Express, and PostgreSQL. Simple, fast, no bloat.
