The current collection type for Business / Corporate is more for a business start-up, with required business cards.
For a corporate event, like a Grand Opening, Business Party, etc, the only current option is to use the Holiday Event collection type, which really isn’t that accurate since a business event can occur at any time of year.
The business / corporate events collection type should be set up much like a wedding collection, with invitations, RSVP cards, envelopes, menus, signs, etc.
