Overview
DCM Guitar School is a music school based in Kill, Co. Kildare, Ireland. Founded by Dan Cassoni in 2013, the school offers lessons in guitar, piano, drums, bass, and ukulele, and runs music camps throughout the year. The school operates with a team of teachers and aims to make learning music fun, engaging, and tailored to each student.
The challenge: No-shows and constant back-and-forth
Before using Koalendar, DCM Guitar School handled bookings through phone calls, emails, and website forms. That meant a lot of manual admin, with time spent answering queries, checking availability, and calling people back.
But the bigger business problem was no-shows.
When students booked over the phone, they could simply fail to turn up. That left teachers waiting, created unnecessary cost for the school, who still had to pay the teachers, and made scheduling harder to manage.
“We were having a few issues with no shows. Someone would book a class over the phone and then they wouldn’t show up… the teacher has to be paid, and that became a problem.” Dan explains.
The school needed a booking system that would reduce admin, make scheduling easier, and protect the business from missed appointments.
The solution: A simple system with payment option
DCM Guitar School found Koalendar through Google after trying other options, including Wix’s built-in booking system.
“We tried the Robo booking system on Wix — it wasn’t very good. I even paid someone to fix it and it still didn’t work.”
After searching Google for alternatives, they tested a couple of other tools (like Acuity) but found them either more expensive or less intuitive. Koalendar stood out for its ease of setup and reliability:
“I found that the quality was great and it was just easier to set up, and it’s worked well since I started using it.”
This is how DCM Guitar School transformed how scheduling is handled with Koalendar:
Online booking link for each teacher
There’s a separate booking page for each teacher, allowing students and parents to:
- View real-time availability
- Choose lesson times that fit their schedules
- Book directly without needing a phone call or email

“If people want to ask questions first they’ll call, and then I just direct them to the online booking instead of me having to tell them what times are available and then they can have a think about it and it's all taken like a while on the phone.”
Calendar sync with Google
All bookings are integrated with Google Calendar, so teacher availability is always up to date:
“I do all our scheduling through a Google Calendar… because I organise all the bookings so we can see their calendars.”
Payments via Stripe at booking
Koalendar is configured to take payments upfront through Stripe, ensuring lessons are paid before they occur. This reduces no-shows significantly:
“They paid for it upfront… if they don’t show up then it’s on them rather than us.”
Rescheduling made easy
Students and parents can reschedule themselves, reducing the need for phone and email coordination.
“With the rescheduling option… they don’t need to ring me. They can just do it themselves.”
The outcome: Less admin work, fewer no-shows, happier teachers
Since implementing Koalendar, DCM Guitar School has seen clear improvements in day-to-day operations.
✅ Fewer no-shows: Because lessons are paid for at the time of booking, students are far more likely to attend. If they don’t, the time is still covered, which removes financial loss for the school.
✅ Time saved on scheduling: Instead of answering calls and checking availability manually, students book their own sessions at a time that works for them.
“Koalendar helps me save time and that's the main reason why I use it... when I'm at home, I don't want to be answering the phone for work.”

✅ Better experience for teachers:Teachers can focus fully on teaching instead of managing schedule changes or handling last-minute adjustments.
✅ More flexibility for students: Students can reschedule their lessons themselves, without needing to call or message the school directly.
Conclusion
For DCM Guitar School, Koalendar brought structure to a booking process that had become time-consuming and unpredictable.
By moving bookings online, taking payment upfront, and letting students reschedule themselves, the school reduced admin, made no-shows less damaging, and gave teachers a more reliable schedule.
What used to require constant calls, emails, and follow-up can now be handled through a simple booking flow, freeing up more time to focus on teaching.
