Hands are full
You're mid-job, on a roof, or driving between call-outs. A phone that rings out doesn't wait — the caller moves on to whoever picks up.
The phone still gets answered when you're under a sink.
A plumber, electrician or heating engineer mid-job cannot reasonably stop to answer a call — and a caller who gets no answer usually just rings the next name on the list. SIMCOAI answers every call, books the ordinary ones straight into your diary, and puts a genuine emergency in front of a person immediately.
The problem
The job that pays doesn't stop for the job that's ringing.
None of this is about the AI being clever. It's about the phone getting answered at all, on the days it matters least to be free.
Out of hours still rings
Boilers fail on Sunday nights and pipes burst before 8am. Somebody has to answer, or decide what genuinely needs answering.
A paper diary doesn't match reality
Whoever answers has to know what's actually free that week — not what a sticky note said an hour ago.
What SIMCOAI does
Built from your own diary, your own rules.
None of this is generic. It only offers what your dashboard says is true.
Books against your real jobs
Set your services and how long each one runs — a boiler service, a call-out, a rewire — plus travel or turnaround buffers, and SIMCOAI offers only times that genuinely work.
Emergencies go to a person, not a queue
Escalation rules you set decide what's urgent. A caller describing a gas smell or a burst pipe is handed to your team rather than booked in for next Thursday.
The caller confirms before it's booked
The appointment is read back and confirmed by the caller before it lands in your diary, so a mis-heard day or time is caught on the call, not on the doorstep.
Returning customers are recognised
A number that's called before is matched to a customer record, so a repeat job doesn't start from a blank page.
You always know what happened
Every call is recorded against the record it created — what was asked, what was booked, what was escalated — so nothing gets relayed from memory at the end of the day.
Nothing outside what you've allowed
SIMCOAI never quotes a price, diagnoses a fault or promises a specific engineer. It books what you've told it exists, and hands the rest to your team.
Common questions
What tradespeople ask before setting this up.
Will it try to diagnose the fault or quote a price?
No. It takes the details the caller can give — what's happened, the address, the best number back — and either books it against a service you've defined or hands it to your team. It doesn't attempt a technical diagnosis or a price.
What counts as an emergency?
You decide, in the dashboard. A gas smell, a burst pipe or no heating in freezing weather is the kind of thing most trades route straight to a person rather than booking as an ordinary appointment.
Can it book a job while I'm on site?
Yes — it reads live availability from your timetable, so nothing needs re-checking against a paper diary when you get back to the van.
Does it know a customer who's called before?
Yes. Returning numbers are matched to one customer record, so their history is already there rather than starting again.
