Paying “on site” is not supported for entry passes or credits. This is intentional, as it would likely create a large number of unpaid orders. Entry passes and credits only become usable after the payment is successfully completed, so allowing on-site payment in the booking flow could confuse clients — they would place an order but wouldn’t be able to use it immediately.
If a client comes to your studio and wants to purchase a credit/pass in person, you can easily add it manually from the client administration see How to Add Credits, Entry Passes, or Make-Up Sessions to Your Clients.
This ensures everything is properly recorded and avoids the need to cancel unpaid orders or deal with inconsistencies.
For first-time offers (e.g. a free or discounted first class), we recommend using a promo codes. Promo codes can be limited to one use per client and provide a clean, controlled way to offer special pricing.
How to set it see in How to Set Up "First Class Is Free".
