Switching booking systems without losing customers: a checklist
You can switch booking systems without losing track of your customers if you export the customer data, secure a list of future appointments and test the new calendar before you turn off the old one. Find out in advance how the data can actually be moved, because import options vary from system to system.

Written by the team behind Stamly at Inovix AS. We sell the booking system we write about, and we show where the numbers come from.
In short
- Keep the customer database and a list of every upcoming appointment before you switch.
- Find out which data the new system can import, and what has to be entered by hand.
- Test staff, services, breaks, opening hours and booking links before you go live.
- Tell customers clearly where to book once the switch is done.
What do you need to keep before you switch?
The customer database and future bookings come first. Find out how your current system lets you export names, contact details and, if possible, visit history. Then gather the rest of the setup: services, prices, staff working hours, opening hours and any time off that's already planned.
Go through which details you need to move, and which you're allowed to. Salons in Norway, like those in the EU, fall under the GDPR. Handle exported files securely and delete temporary copies once you no longer need them. Don't carry marketing consent across until you've checked how it was recorded.
How do you avoid losing appointments that are already booked?
Choose a changeover date and make a list of every appointment after it. Compare the old calendar with the new one before you send customers anywhere. Look hardest at appointments that were moved, cancelled or booked outside normal opening hours, because that's where things slip.
A short overlap can help, with one person keeping an eye on both calendars. Customers shouldn't see two places to book, though. Decide which system is the real one during the changeover, so staff don't create double bookings.
What data can be moved to Stamly?
Stamly helps the salon import its customer list from a CSV file. Arrange the import with us when you start. The file can contain:
- Name, or first name and surname.
- Phone number or email address. At least one of the two has to be there.
- The salon's internal note, if you want it brought over.
- Dates of the first and last visit, if the file has them.
The CSV file can use commas or semicolons, and UTF-8 or Windows-1252 encoding. Dates can be written as 2026-09-30 or 30.09.2026, for example. Agree a secure way of sending it with us before you send a file containing customer details.
We do a test run on the file before anything is added, and check for missing details and duplicates. Importing a customer does not give consent to marketing. If a customer already uses Stamly with another salon, the customer has to approve the link to your salon.

How do you tell customers about the switch?
Once the new system works, update the booking link everywhere: your website, your social profiles and your Google Business Profile. If you've checked that existing appointments still stand, say so plainly. A small note at the front desk for the first few weeks does no harm.
Ask a colleague to book through the new system exactly as a customer would. Check the confirmation and the entry in the calendar. Only remove the old booking link when all of that works.
A checklist for changeover day
- Check the basics. Customer database, staff, services and opening hours.
- Check upcoming appointments. Compare them with the list from the old system.
- Test booking. Try a new appointment, a reschedule and a cancellation before customers get the link.
- Update the links. Use the new address everywhere customers find the salon.
- Agree who helps. Make sure every staff member knows who to contact if something goes wrong.

Questions and answers
Can I switch booking systems without losing my customer list?
Usually you can export customer data from the old system. Check which fields the new system accepts before you close the old one.
What do I do with appointments that are already booked?
Make a complete list, and check that every future appointment is dealt with in the new calendar before the changeover.
Can Stamly import everything from my old system automatically?
The customer import doesn't move future appointments, full treatment history, photos, gift cards or points balances. These need to be sorted out separately before the switch.
When should I update the booking link?
When the new system has been tested and is ready to take bookings, so customers aren't sent to something half-finished.
Do I need to tell customers about the switch?
Tell them clearly where to book from now on, and be clear about how existing appointments and personal data are handled.
