I am looking at different Calendar/Event Booking solutions to find a way to do this:
Having the 'calendaring/event data' handled by something like jEvents Pro / RSVP Pro but the billing being passed on to Hikashop so that we don't have 2 different client workflows as there are add-on items, downloadable and shippable goods that are handled by the very capable Hikashop eCommerce solution... to provide a better customer experience, we want only 1 customer workflow/interface...
FYI, there is no pre-sales contact us form, having to create an account to get into a forum to ask a question is not the simplest process and not conducive to sales... also, from the website when you look for answers to things many come up under Gold or some other plan so if we are Pre-Sales and are looking to see if your solution does something and how it does it we hit a paywall

Sincerely,
Emmanuel
