Automatic. And actually simple.

Most business software is one or the other. It either does the work and takes a month to learn, or it's easy because it barely does anything. This does the work and stays out of your way.
Maintenance plans bill and book themselves The customer is charged on schedule and the seasonal visit lands on the calendar without anyone remembering.
Estimates become jobs become invoices One approval from the customer moves it along. Nothing gets retyped.
Pay and commission add themselves up Service calls and installs each carry their own rule, settled and payroll-ready.
Customers get reminded before the season The tune-up reminders go out on their own, so the calendar fills before the phone rings.
If you can use WhatsApp, you can use this No manual, no training course, no settings to work out. Open it on your phone and the next thing to do is on the screen in plain words.
We set it up — not you Your rates, your team, your existing customers and jobs are already in it on day one. You start on a finished system instead of an empty one.
In the language you actually speak English, Russian, Spanish and Turkmen today — Ukrainian and Uzbek next. And when we set you up we translate the screens your office works in, not only what your drivers see.

Built-in AI

Paperwork that reads itself. You see the price before it runs.

Take a photo or upload a PDF. StackViro reads it and fills in the form for you to check. By default, nothing is read until you confirm.

Receipts and supplier invoices fill the expense form

Photograph a fuel receipt or upload a supplier invoice. The merchant, date, amount and a suggested category fill the form for you to check and save.

Business cards become contacts

Photograph a business card. The name, company, title, phone, email and address become a contact.

Questions, answered simply

What owners usually want to know before the first call.

Can it handle maintenance agreements?
Yes — recurring plans bill your customers on their own schedule and drop the seasonal visits onto the calendar automatically, so nothing depends on someone remembering.
Can we track what equipment is at each house?
Yes. Every address keeps its own equipment history, so the technician knows the model and the last service before arriving.
Do you handle install jobs, not just service calls?
Both. A quick service call and a multi-day install need different handling, and the platform treats them differently rather than forcing everything into one shape.
We add techs every summer. Is that painful?
No — hiring, onboarding paperwork and signed agreements are built in, so a seasonal tech can be working, with everything signed, the same week.
