SmartProposal: Win more clients. Send, sign, and get paid in one link

Hi Product Hunt! 👋 I'm jaewon, the maker of SmartProposal. As a freelancer and agency owner myself, I was always frustrated by the fragmented client onboarding process. Sending a PDF, waiting for an email reply, sending a separate e-signature link, and then sending an invoice... it creates way too much friction and lowers the closing rate. I built SmartProposal to solve this exact problem. It's an all-in-one proposal tool designed specifically for freelancers and small agencies who want to look professional and close deals faster. ✨ Key Features: Interactive Proposals: Create beautiful, web-based proposals in minutes. Read Notifications: Stop guessing. Know exactly when your client views the proposal. One-Click Sign & Pay: Clients can legally sign the document and pay the deposit on the exact same page via Stripe. Affordable for Freelancers: Start for free, or upgrade for just $15/month (no hidden per-user fees). I built this to scratch my own itch, but I'm incredibly excited to share it with the community today. I'll be hanging out here all day to answer your questions and hear your feedback. Let me know what you think! Also, if you run into any inconveniences, please shoot me an email at bcc101010@naver.com I'll fix it right away! 🚀
