Heating & air conditioning (HVAC)
AirCooling
12 years of paper sheets, over
From an entirely paper-based operation where quotes took over a week to go out, to a platform where everything is centralised and quotes leave the same day.
[01]The context
11 technicians, a business still run on paper
AirCooling installs and maintains heating, air conditioning, refrigeration and ventilation systems for B2B and B2C clients in the Brussels region, with 11 technicians in the field and partnerships with Daikin and Fujitsu. Despite this size, the entire operation — quotes, client tracking, scheduling — still ran on paper sheets for 12 years. A method that worked while the business stayed small, but broke down under volume: lost sheets, scattered information, no centralised record.
[02]Day to day
The pain points we removed
Concretely, here is what made daily management impossible before we stepped in.
Quotes taking over a week
Every quote written by hand on a paper sheet, then typed up later. Clients sometimes waited over a week to receive anything — plenty of time to turn to a competitor.
Lost sheets, vanished information
Site notes, client details, job specifics: all on loose paper. One missing sheet meant a forgotten client or a job to redo from scratch.
Nothing centralised
No overview of B2B and B2C clients, ongoing contracts or job history. Every piece of information lived in the owner's head or in a stack of papers.
Manual appointment booking
Appointments arranged by phone with no clear view of the 11 technicians' availability. Constant risk of overlaps or forgotten slots.
[03]What we built
What we put in place
A web + admin platform to centralise quotes, clients and scheduling, delivered and deployed on aircooling.be.
Quotes generated the same day
Before
Quote written by hand, typed up later, sometimes sent out a week after the initial request.
After
Quote created and sent to the client the same day the request comes in, directly from the admin.
Centralised client management
Before
Client details and history scattered between paper, memory and isolated emails.
After
Every B2B and B2C client in a single record, with job history and linked quotes.
Appointment calendar (Cal.com)
Before
Appointments taken by phone with no overview of technicians' real availability.
After
Booking built in via Cal.com, clear visibility on available slots for all 11 technicians.
Digitised internal management
Before
No internal tool: every job or contract had to be tracked from memory by the owner.
After
The entire internal workflow — job tracking, contracts, quotes — brought together on a single platform.
[04]The outcome
What truly changed for the owner
Quotes go out the same day, no more week-long wait for the client
No more lost paper sheets — everything is centralised and accessible
Clear overview of all B2B and B2C clients and their history
Scheduling for 11 technicians handled simply through the appointment calendar
Internal management finally digitised, after 12 years of paper
[05]Client's words
« 12 years in the trade and until recently I did everything on paper sheets. Sheets got lost, clients waited over a week to get a quote. Today my quotes go out the same day, everything is centralised, and I wonder how I managed for 12 years without this. »
Quotes sent the same day — no more paper sheets
