The Register OS is an AI business-judgment platform for trade contractors. It refuses code, safety, and technical installation questions — and focuses only on what actually moves your money: pricing, margin, bids, lead ROI, cash flow, and hiring timing.
"I swear, if one more homeowner says, 'well ChatGPT said…' I'm walking out of the house."

"ChatGPT said it's the capacitor."
It was not the capacitor.

"A young apprentice gave me an answer he found using ChatGPT. The answer was wrong."

"I've also seen it be very wrong but convincing — so it's not 100% reliable as of now."

"Should I raise my maintenance agreement price?" "Can I afford another technician?" "How much cash should I reserve for the slow season?" "Is this lead source worth it?"
Loaded-cost breakdowns. Margin targets. Lead-source cost-per-booked-job comparisons. Cash reserve targets by month. Hiring breakeven calculations. Real numbers, sourced from trade benchmarks.
Ask it about Manual J, refrigerant charge, duct sizing, code compliance, EPA 608, or diagnostics — and it says no. Every time. That refusal is the trust mechanism.
The Register OS doesn't replace ServiceTitan, Jobber, or Housecall Pro. It tells you whether you're using the right one, pricing the right way, and banking enough for the slow months.
This isn't a limitation. It's the product. The moment an AI gives a wrong refrigerant answer, a compressor dies, or a customer gets hurt — the trust is gone forever. We'd rather be the tool that says no.
Sizing equipment for a space is engineering. That's for a licensed professional with the building specs, not an AI.
Refrigerant handling requires federal certification. A wrong answer can damage equipment or violate federal law.
Airflow design belongs to the mechanical engineer or your senior tech with measurement tools.
Local mechanical and plumbing codes vary by jurisdiction. Wrong answers fail inspections or void insurance.
"Why is the compressor short-cycling?" — a wrong diagnosis wastes a truck roll and can make things worse.
Wrong wire sizing can start a fire. Wrong gas pressure can cause carbon monoxide exposure. Life-safety = hands off.
Wrong specs void warranties. Check the OEM install manual or call the manufacturer's tech support line.
Plumbing code, backflow prevention, and cross-connection questions are jurisdiction-specific and safety-critical.
Ask it any of these and it says: "That's a technical, code, or safety question. I don't answer those — a wrong answer could create liability. I focus only on pricing, margin, cash flow, and business judgment for your trade."
Ask any business question. Get dollar math, not platitudes. "Should I raise my maintenance agreement price?" "How do I respond to a customer who says my quote is too high?"
Enter material cost, labor hours, labor rate, overhead, and proposed price. Get true cost, gross profit, net margin, and a warning if your bid is below target.
Compare Google LSA, Angi, Thumbtack, and HomeAdvisor by cost-per-booked-job, not cost-per-lead. Get a clear scale/test/kill recommendation per channel.
Enter monthly revenue and fixed expenses. Get your peak saving months, projected cash gap, weekly savings target, and reserve goal for the shoulder season.
Enter average job value, jobs per week, tech labor cost, truck/insurance/tools, and utilization. Get breakeven revenue, profit contribution, and a safe-to-hire signal.
Customer says "your price is too high" or "ChatGPT says it should cost less." Get a professional, firm, non-defensive response that protects your margin.
Drag the sliders. Most HVAC and plumbing owners have never seen this calculation. This is what The Register OS shows you on day one.
From pricing decisions. Not more leads. Not more trucks. Not more hours. The Register OS exists to help you capture exactly this.
"I'm using Jobber, but honestly, I've been finding it way too expensive for what it offers."

"We pay $120,000/yr to ServiceTitan. I'm having a possible fraud case where our estimates go to competitors."
BBB Complaint · 2026
"ServiceTitan demanded an early termination fee of $67,230 — the full remaining balance — despite never having delivered a functional platform."

"They've recently submitted another round of rate increases. Ours went up 65%."

The Register OS doesn't replace your dispatch software. It sits beside it and tells you whether you're using the right one, pricing the right way, and banking enough for the slow months.
First 100 contractors only. No credit card. No demo call. We'll email you when your seat opens.
Because that's where AI fails trades. Contractors have watched ChatGPT misdiagnose capacitors, apprentices cite wrong AI answers, and homeowners weaponize AI to argue quotes down. The refusal IS the product — it's what makes The Register OS trustworthy. A wrong refrigerant answer can kill a compressor. A wrong code answer can fail an inspection. We don't play with that.
No. The Register OS sits beside your dispatch/scheduling software. It doesn't handle dispatch, routing, or invoicing. It handles the business judgment layer: pricing, margin, lead ROI, cash flow, hiring timing. Think of it as the business advisor that your dispatch software doesn't have.
Three ways. First, The Register OS has a hard wall against technical questions — ChatGPT will happily give you a wrong load calculation. Second, it's trained on HVAC and plumbing business benchmarks: lead costs, margin ranges, seasonal cash patterns, technician replacement costs. Third, it gives you dollar math and action items, not essays.
The Register OS supports both HVAC and plumbing contractors with 3–30 employees. The business judgment layers are nearly identical: pricing, margin, lead ROI, cash flow, hiring. The refusal list is trade-specific — plumbing code, backflow, and cross-connection questions are refused just like HVAC refrigerant and Manual J questions.
Yes. The first 100 founding members keep $49/month as long as they stay subscribed. Even as features are added and the regular price increases, founding members keep their locked price. No contract, no termination fee, cancel anytime — but if you cancel and rejoin later, you rejoin at the current regular price.
Phase 2 of The Register OS includes embedded financial products: instant payouts for completed jobs, invoice factoring, and working capital advances. Because the platform already sees your margins, cash-flow timing, and job pipeline, it can underwrite faster than a traditional lender. These features will be handled through appropriate regulated partners. For now, it's a "coming soon" section — the MVP is the SaaS subscription and business tools only.
Not for the MVP. The Register OS works standalone — you enter your numbers, it gives you judgment. Future versions will integrate with QuickBooks and field-service platforms for automatic data sync, but the founding cohort starts with manual input. Less friction, faster onboarding.
No. The Register OS provides business-judgment tools and estimates for planning purposes only. It does not provide legal, accounting, engineering, code, safety, or compliance advice. You are responsible for verifying all trade-specific requirements. Any future financing features will be handled through appropriate regulated partners.
The Register OS is the AI business manager for trade contractors. It refuses what it shouldn't touch, and focuses on what actually moves your margin. $49/month, locked for life, for the first 100.
