I needed to invoice a client in USDT. Couldn't find anything simple. Everything required MetaMask or 30min enterprise setup. So I built Billify. What's different: → Client pays with card or crypto — no wallet needed → AI writes follow-up emails for unpaid invoices → Stripe + 200+ crypto coins on the same invoice → Invoice in 60 seconds, free to start Built for freelancers and Web3 teams tired of losing money on bank transfer fees.
