After 5 Years In B2B Sales, I Taught Myself To Code And Built An AI Proposal Too

So I built what I wished existed: PropelAI Studio (propelaistudio.com)

How it works: 1. You type a one-line brief (e.g. "5-page website for a catering business in Abuja, 450k&quot 2. The AI writes the full professional proposal — scope, milestones, terms 3. You send your client a link — they open it on their phone and e-sign.

No app, no account needed. 4. From the signed proposal, generate the invoice with a Pay Now button — card, bank transfer, or USSD.

Also in there: contracts, client dashboard, WhatsApp sharing, Zapier integration (it's a listed Zapier app).

Stack: React + Supabase + Netlify.

It's free to try — 3 AI proposals, no card needed.

I'd genuinely appreciate honest feedback — the good, the bad, and the "this will never work in Nigeria." What's missing? What would you want before using it with your own clients?
