I'm building an ecommerce site for a massage therapist. For the ecommerce side (couple little products) I'm leaning toward oscommerce, but the client also wants a way to manage her appointments online.
Does anyone know of open source PHP based online schedulers?

Seems like there are a few SaaS schedulers out there. Looking there these two seem pretty good:

http://acuityscheduling.com - has a free version and has a basic ecommerce site for a products catalog
https://www.fullslate.com/ - also looks free, but doesnt have anything for ecommerce

Has anyone here used them? Any other recommendations for a scheduler, either PHP or preferably one which has an ecommerce plugin?
