I am looking for advice for the best workflow for selling and scheduling service products on Squarespace while using Acuity. I would like to be able to sell and schedule directing from the store (because I feel it is the most intuitive) but it seems in order for that to work, I would need to send an email with a link to schedule (which we run into ensuring they don't exceed appointments paid for). The other option would be to embed the scheduler within a page about the service and let them pay and book from the embedded portion. Please shed some light on this and point out any other possible options or pitfalls. We just expanded to services on the site, so this is fairly new. Thanks in advance.
