Meeting with Suzi. She had a new analogy for me (for the dog care demo site), think of an operating room... patient(s), doctor(s), other assistants, etc. Complex scheduling stuff. Switched over to some questions on a frozen yogurt demo site. Suzi has a need for items and sub item attributes, extras, or modifiers. This would need to be tracked per main item but basically, a pool or preset group of extras that could be hung on or attached to an invoice or cart line item. Imagine, a main item with sub options. These could be called options, extras, sizes, flavors, colors, modifiers, attributes, etc. I'm not sure. We spent some time going over an ice cream store (frozen yogurt) type options and needs.
