Updates, ideas, and practical notes from Lumina Sales on building and selling AI software.
Follow via RSSA build fee rarely dies because the number is too big. It dies because it moves your deal from the money an owner spends alone into the money almost nobody is spending right now. Here is the budget math behind that, what year one looks like either way, what monthly-only pricing actually costs you, and the work that should still carry a setup charge.
ChatGPT waits for a person to open it. What you sell answers the phone at 2am when nobody opens anything. Here is the one-sentence answer to the objection, what ChatGPT Business actually costs and does, what it really takes to put a model on a phone line, and when the prospect is right and you should walk.
A demo node is one working piece of the system you sell, running live on a page your prospect opens in their own browser. Here are the six nodes, what each one proves on a call, how to sequence them, and where the demo site falls down.
The Census Bureau puts US business AI use at 19.8%, with firms of four or fewer employees under 20% and flat for six months. Meanwhile voice model pricing fell and quality rose. That gap is a distribution problem, and it is the whole reason an AI agency has a market.
A published Lumina Sales demo carries your logo, your colors, your subdomain and your booking link. It also carries one line saying the AI is a demo and its bookings are simulated. Here is what that means in front of a real prospect, and the three places the white label has a seam.
HVAC is the best first vertical for a small AI agency: a violent seasonal curve, a phone that is the only intake channel that matters, and a labor market that blocks hiring. Here is the demo to build, the price to charge, and the four deals to walk away from.
Ten clients takes about a thousand first-touch emails, two hundred dials, and a demo you can hand over on the first call. Here is the real math, the objection you will actually hear, and who this does not work for.
OpenAI put GPT-Live-1 into the API on September 10, 2026. It listens and speaks at the same time, and the voice layer costs $0.05 a minute. Here is what that changes for an agency selling AI phone systems to local businesses, and the four things it does not fix.
Building your own voice stack is cheaper per minute and more expensive per month. The vendor fees are public and small. The demo site, client portal, branding and intake are the parts nobody quotes you on.
Three things happen between a signed deal and a live build: intake under your brand, the fulfillment order at wholesale, and the client moving into your portal. Here is the full sequence, who owns which piece, and why the client's own answers set the timeline.
The average US roof replacement hit $17,631 in 2025, so every call a roofer misses during a hail week is a five-figure bid handed to whoever picked up. Here is the full playbook: who signs, what to put in the demo, what to charge, and the four roofers you should not bother selling.
Your delivery cost on the top wholesale tier is $500 a month plus the $49 platform fee. Everything above $549 is yours, with no build invoice to earn back first. Here is the input-cost math, the three ways to set retail, and where the model breaks.
