Yes. Every new salon can use KRI free for 1 month, with every feature included, and you don’t need to enter a card to start.
When the trial ends
The trial runs for calendar months from the day you sign up and ends at midnight, Helsinki time, on the same day of the month. If you sign up on the 15th, your trial ends on the 15th of the following month. If that month is shorter, it ends on its last day: a trial started on 31 January ends on 28 February in a normal year.
Adding a card
You can add a card on the Billing page of your dashboard at any point during the trial. Your plan is billed monthly from there.
Making the trial longer
A salon you invite gets one extra month of free trial. Each salon has a permanent invite code, which you will find in your dashboard under Billing, and when the business you invited pays for its first month, you both get the next month free. A promotional code entered during the trial can lengthen it as well.
