Chasify

The SaaS that helps freelancers and small businesses follow up on unpaid invoices.

Chasing a client who hasn't paid is tedious, so it keeps getting pushed back. Chasify takes it off the plate of freelancers and small businesses. A standalone product, designed and built end to end.

  • React
  • Vite
  • TypeScript
  • PostgreSQL
  • Cloudflare R2
