I built Stampwerk because I was paying $29/mo for HoneyBook and using two features: proposals and invoice reminders. That's it. Two features out of fifty. Then HoneyBook hiked to $59/mo. AND.CO shut down the same month. Bonsai got acquired by Zoom. Three displacement events in sixty days. Dubsado is so complex that people charge $500-3,500 just to set it up. That tells you everything about how broken this market is. Stampwerk does four things well: 1. AI proposals -- answer 5 questions, get a structured proposal with scope, timeline, and pricing 2. Auto-generated contracts from accepted proposals 3. Stripe invoicing with payment links 4. A follow-up daemon that chases overdue invoices in 3 escalating steps $12/mo. Free tier: 5 proposals and 5 invoices/month. No credit card required. The AI follow-up daemon is the part nobody else has. Most tools make you manually "send reminder." Stampwerk sends a friendly nudge at 3 days, a firmer reminder at 7, and a final notice at 14. Configurable per client. Built with FastAPI + Next.js. The AI runs on Groq (Llama 3.3 70B) -- fast inference, low cost, no OpenAI dependency. https://stampwerk.com
