The front end is easy. Lovable, Claude, Cursor — done in hours. But the moment a client needs real pricing logic, business rules, or calculations — you're either hard-coding it into prompts or writing custom backend code. Both are a nightmare to maintain when something changes. I built a solution. Here's how it works: → You vibe code the front end (any tool) → It connects to n8n → n8n pulls the business logic from Quotix (the engine I built) → Quote calculated, result returned to the front end → Lead pushed to GoHighLevel automatically No black box. No hard-coded prices. Full control over the business logic from one place. https://www.loom.com/share/256a189b6ba74aa2bf53aeab14569bc0 I'm looking for people to test this. If you build for solar, HVAC, roofing, electrical — or any service business that needs on-site quoting — drop a comment or DM me. Free to test.
