One customer, not one per module
Most businesses end up with the same customer in three systems: the one that bills them, the one that emails them, and the one that schedules them. Crescove models the customer once, at the Brand level, and lets modules attach to it.
- A customer who subscribes and later books service is one record
- Contacts belong to the customer, not to a single transaction
- Notes and tags survive the work that prompted them
