I need a simple scheduling option for potential clients to book a free 15 minute Zoom meeting. At first glance I thought SquareSpace Scheduling was free on all plans - is this correct? I've also just come across the Acuity Scheduling option which looks like it's an additional £11 for the cheapest plan. Can someone please clarify the options for me and their associated costs? Also, do I need a payment provider to process free appointments?
