Estimates
A customer emails about a water heater. You get a priced estimate, from your own price list, ready to send.
For plumbers, electricians, HVAC, roofers, and landscapers
You do the job. Virtual employees do the paperwork.
Zentrol gives your trade business a small office team of virtual employees. They write the estimates, the schedules, the reminders, and the invoices. You check the work before anything goes to a customer.
The job ends at five.The estimates, the invoices, and the callbacks start after that. Zentrol takes that work.

How it works
How it works.
Write the task
Say what you need in plain words. For example: "Write an estimate for the Parker water heater job."
Give it to a virtual employee
Each virtual employee has a role, such as front desk or billing, and knows your prices and your rules.
See the progress
Every task shows who has it and where it stands. If the virtual employee needs an answer, it asks you.
Check the work
Read the result, ask for changes, or approve it. You send every email and text yourself.
You stay the boss
You stay the boss.
Virtual employees do the writing. Every decision stays with you.
Nothing is sent without you
A virtual employee can only write a draft. You read it, and you press send. There is no way for it to send on its own.
It works by your rules
Write your company rules once, such as your prices and what you never promise. Every virtual employee gets them on every task.
Your files stay on your computer
Customer lists, prices, and schedules stay in a folder on your own computer. The virtual employees work on them there.
It asks when it is not sure
A virtual employee that is missing a fact stops and tells you what it needs. It does not guess.
FAQ
Questions owners ask us first.
Do I need to be good with computers?
No. You write a task in plain words and read the result. Setup means one app on your office computer, and a guided setup takes you through it.
Can it send a wrong price to a customer?
Not on its own. A virtual employee can only write a draft. You read each email and text, and you are the one who sends it.
Where does my customer list go?
It stays in a folder on your own computer. The virtual employees read and update the files there.
Does it replace my office manager?
No. It takes the writing and the lookups, so your office manager has time for customers and crews.
Which tools does it work with?
It writes email drafts into your Gmail, and text messages that you send from Zentrol. It reads the files you already keep, such as spreadsheets and documents.
What does it cost during the beta?
The beta is free. Your virtual employees run on a Claude subscription, which you pay to its maker.
