When people are paying for a calendar booking, they should be able to purchase products as add ons/upsells. Only a few booking platforms (Accuity & SimplyBook.me) allow this upsell natively in calendar bookings. GHL would have a huge advantage if this feature was added.
ALSO, we're already able to create custom forms with products and add them to calendars. HOWEVER, the products don't show up once the form is integrated in the calendar. We're so close to being there!
Its perfect for production studios (adding 4K video to a standard recording), classes (selling if attendees have to bring anything themselves), salons (selling hair washing/styling products when booking), etc.
Please make this happen. This feature would change the way my business operates and keep me from moving to another booking software.
