Since the 8.4.9 version of Salon Booking System – PRO edition, you can request your customers to complete their payments online.
If you have the online payment enabled, and you are asking a deposit to confirm the reservation, then you can request the customer to complete the remaining part of the booking amount to be paid online.
Just open the Web App, look for the customer reservation, and click on the “complete payment” icon.
Once done, an email will be sent to the customer with a link to complete the payment online.
