The problem

One AC unit. Five possible outcomes.

A typical small shop installs 50-300 units a year. What happens after 12 months? Either you call them one by one (and lose days), or - most often - you forget about them. And the customer calls the first technician they find on Google.

Without ExpireMate

Excel, a paper notebook, and - silence.

  • You keep install dates in your head or in a spreadsheet no one opens
  • 12 months later the customer hears nothing from you
  • The unit runs without cleaning, breaks down - and you get the blame
  • The customer calls another technician because you never reminded them
Most of that repeat-service revenue quietly disappears - simply because no one calls the customer back.
With ExpireMate

Log it once. The system does the rest.

  • Log the customer and unit when you install it - 45 seconds
  • On day 365 exactly, an SMS goes to the customer in your name
  • The customer replies YES - you see the appointment in your calendar
  • The customer stays yours. For good.
When every unit reminds the customer on its own, the ones you'd otherwise forget come back - same unit, same technician.
How it works

Four steps. One minute per customer.

We don't ask you to change how you work. Just log the customer when you finish the install.

1. Log the AC unit

Customer name, phone, model, serial number, install date. Done in 45 seconds on your phone while you're still on site.

2. The system counts the days

A year later (or whenever you set) ExpireMate knows that unit is due for its annual service.

3. Automatic SMS

The customer gets a message in your name with the device details and an invitation to book. Personalized, not spam.

4. You book the service

The customer says YES - you see the slot in your calendar, show up, invoice. The system sets the next reminder.

What you get

Built for small shops, not corporations.

No bloated modules. Everything you actually need so you don't lose a customer - and nothing else.

Core feature

Automatic SMS reminder after 12 months.

The heart of the system. The customer gets the message exactly when they should - not a day early, not three weeks late. It carries your name, the unit details, and a clear call to action.

Set it however you like - 6 months, a year, two. The system tracks each unit's lifecycle separately.

CRM

Every customer and every device.

Name, phone, address, AC model, serial number, service history. All in one place, searchable by anything.

Calendar

Booking without the hassle.

The customer says YES - you see an open slot, click, booked. Syncs with Google Calendar.

History

What was done last year?

Every service stays logged on the device. You know what you replaced and when, with prices. No one can dispute your work.

Mobile

Works on your phone. Works in the field.

Everything is built for techs who spend most of their time on site. Log a unit from your phone while the customer makes coffee. It syncs automatically when you get back to the office.

What losing customers costs you

Run the numbers for your shop.

Move the sliders. You'll see how much money evaporates each year because no one calls customers for their annual service.

How many units do you install a year?200
Average price of an annual service€45
Out of 10 customers, how many come back for a service today?4 of 10

This assumes automatic reminders lift your return rate toward ~75% - a projection to size the opportunity, not a measured average. Adjust the sliders to your own numbers.

"I'm building ExpireMate because I watched small HVAC shops do great installs and then lose those same customers a year later - not from bad work, but because nobody reminded anyone. The whole product is one idea: log the unit once, and never lose that customer to a forgotten service again."

Founder, ExpireMate

FAQ

Questions people ask us.

No. The message comes from your name (or your shop's name) and contains the exact details of their device - model, install date, recommended appointment. It reads as if you wrote it yourself. You can further customize the text on the Pro plan.
No. We send the SMS from our servers through certified carriers. You just log the customer; we handle everything else.
Replies arrive in your CRM in real time. You get a notification "Marko replied YES - book an appointment". One click opens the calendar and you set a time.
Not right away. The trial gives you the whole product: you log customers and units, and reminders get scheduled and show up in your calendar. The sending itself starts once you buy a message bundle. We say so up front so the first due date doesn't surprise you.
Between €0.155 and €0.18 per message, depending on bundle size - the bigger the bundle, the cheaper the message. You only pay for what you send, and unused messages roll over to the next month.
10 minutes for the basic setup. You can do all of it from your phone - no computer needed.
We do, for free. Whether your list is in Excel, a paper notebook or your phone - send us the file or photograph the pages and we'll enter it for you. Nothing to retype.
Then don't use one. All you have to do is log a customer from your phone, the way you save a new number in your contacts. We walk through the setup together over the phone, and we enter your existing customers for you.
Your customers are yours. Only your team sees them - the people you invite into the account. We don't sell your data, don't share it with other shops, and don't use it for advertising.
No. A CSV export of all customers is always available, before and after cancellation. We don't hold you hostage - if you don't like it, you leave, and your data goes with you.
Yes. ExpireMate is a web app - it runs in any browser, and you can add it to your phone's home screen like an app. No app store, no installs.
