Quick Answer: SMS Reminder Bot for a 2-5 employees HVAC business costs £900 as a one-time build fee. Ongoing tool subscriptions (Twilio, Google Workspace, etc.) add £34/month. Most HVAC businesses recover the build cost within 2 months from reduced no-shows alone.

What You Are Actually Paying For
An SMS Reminder Bot is a custom automation that sends appointment confirmations and reduces no-shows. When you buy SMS Reminder Bot, you are not buying a subscription. You are buying a one-time build of a custom automation that handles no-shows for your specific business.
The £900 covers:
- Twilio SMS integration
- Make.com workflow logic
- Calendar sync (Google/Outlook)
- Custom message scripting
- Testing and handover
You own every tool and every workflow. There is no SaaS lock-in. The system uses Twilio and Make.com to execute the logic, ensuring reliability without monthly build fees. I built this for a HVAC client in Manchester who recovered the cost in 6 weeks.
Cost Breakdown
| Item | Cost | Notes |
|—|—|—|
| One-time build | £900 | Fixed price, no hidden fees |
| Twilio (SMS/voice) | £15/month | Pay-as-you-go, scales with volume |
| Google Workspace | £10/month | If not already using |
| Make.com | £9/month | Automation platform |
| Total monthly | £34 | After build is complete |
Compare that to the cost of Receptionist (£22000/year) or Manual reminders (£3900/year).
External data confirms SMS engagement rates remain high compared to email Twilio pricing. Field service businesses lose significant revenue to missed appointments according to industry reports ServiceTitan benchmarks.

Is It Worth It? The Numbers
For a 2-5 employees HVAC business:
- Cost of no-shows: £5400/month
- Cost of SMS Reminder Bot: £900 one-time + £34/month
- Payback period: 2 months
- 5-year savings: £36000
The numbers are conservative. They do not include the value of your time, the revenue from faster response times, or the commercial contracts you can pursue with the hours you get back.

Frequently Asked Questions
Q: Are there any hidden costs?
A: No. The build is £900. Tool subscriptions are separate and typically £34/month. I tell you every cost upfront.
Q: What if my business grows?
A: The system grows with you. Adding a new technician or location usually takes 1-2 hours of configuration. No extra build cost for minor changes.
Q: Can I get a refund if it does not work?
A: I do not offer refunds — but I do offer a diagnostic call first. If I cannot help your specific situation, I will tell you before you pay anything.
Q: Do you offer payment plans?
A: Yes. For builds over £500, I offer a 50/50 split: 50% upfront, 50% on completion.
What People Also Ask
Q: How long does setup take?
A: Setup takes 5 working days. This includes configuration, testing, and handover training for your team.
Q: Does this work with ServiceTitan?
A: Yes. The system integrates with common tools like ServiceTitan, Jobber, and Simpro via API or email parsing.
Q: What happens if a customer replies?
A: The workflow captures replies. If a customer needs to reschedule, the system flags this for your admin team to handle manually.
