We have recently moved from a competitor and sorely miss the tips on card feature we used to have. When payment is initated from a booking and the card reader is active/ready for payment, it would first present the customer with a tip screen. This screen was configurable with percentages e.g. 5%, 10%, 15%, None, etc. A client could select an option and that would automatically add the tip to the sale and show under tips for that invoice. Since moving from the competitor we have seen a huge downturn in tips on card, so for us this feature is hugely important for our stylists.
