CRM needs nothing else switched on. It stands alone, and it talks to its neighbours rather than reaching into them:
- A party can be linked to a Customer or a Donor you already have. The link points at the master record — CRM never copies or duplicates it.
- Sales and Donations keep owning their transactions. When conversion arrives in a later release, a won opportunity will become a quote or a first donation through those modules' own screens and services — CRM will never write into their tables.
