Sound familiar?
Running a plumbing business is hard enough
Missed calls are missed jobs
A homeowner with a leak calls three plumbers and hires the first one who answers. If you are elbow-deep in a geyser, that is not you.
Evenings lost to callbacks
A day on the tools, then two hours of quoting, confirming, and diary juggling at the kitchen table.
No-show customers
You drive 40 minutes and nobody is home. Fuel burned, slot wasted, nothing to invoice.
WhatsApp AI assistant
Answers while you are under the sink
Customers message your business on WhatsApp and the assistant replies instantly: what you do, when you can come, and it books the callout with the details you need. You see the job on your calendar when you surface.
- Instant replies around the clock
- Books callouts against your real availability
- Hands over to you for complex jobs

FAQ
Frequently asked questions
How much does Calenxo cost for a plumbing business?
A solo plumber pays $10 per month. Teams of up to 10 pay $39, larger firms $99 for unlimited team members. Every plan includes the WhatsApp assistant, booking page, and reminders. Free 14-day trial, no card required.
Can customers book emergency callouts?
You control your bookable hours and slot types. Many plumbers offer standard callout windows online and keep emergencies on WhatsApp, where the assistant flags urgency and you decide whether to squeeze the job in.
Can I collect job details before I arrive?
Yes. Attach an intake form to your booking types asking what the problem is, where it is, and anything else you need. Answers land on the booking so you arrive with the right parts.
How do I get paid?
Take deposits at booking, and settle the balance on site with checkout or send a pay-by-link when the job is done. Every payment is recorded against the customer and the job.
