A-000 COVER SHEET

Every call answered. Even when you're on the job.

I set up AI offices for small businesses: a receptionist that answers in English and Spanish, follow-up that doesn't forget, and a morning digest of what needs you. I run the same system in my own three companies in Texas, Mexico and Florida.

A-101 HOW THE OFFICE WORKS

Your calls, texts and emails go to one desk. You stay the one who says yes.

The AI answers, asks the right questions, and writes it down. Anything a customer will read, anything that spends money and anything that promises a date or a price waits for your approval.

G-002 WHY LISTEN TO A BUILDER

I built this for my own companies first.

I run a home-building company in McAllen, a building-materials store in Tulum and a last-mile trucking company in Miami. Three businesses, two countries, two languages, and a phone that never stops.

The agents that help me sort email, summarize calls, draft follow-ups and write the morning digest are the same ones I install for you. When something breaks, it breaks on my business first, and I fix it there.

What I learned doing it →
  • Answers in English and Spanish, and switches when the caller does.
  • Nothing goes to a customer until a person approves it.
  • Follow-up stops after four touches. No spam, no robocalls.
  • One channel per topic, so you know what decision you're about to make.
  • Works with the tools you already pay for: your phone line, Gmail, WhatsApp, your CRM.
  • Installed in about two weeks. You own the accounts and the data.

What I learned running three companies with AI agents

A home builder, a materials store in Tulum and a Miami trucking company, run with AI agents that draft and wait for approval. What worked, what broke.

Markup vs. margin: the math that quietly eats a builder's profit

Markup and margin are not the same number. The formulas, a conversion table, and a $40,000 job example that shows where the money goes.
