module-crm

What it is

module-crm.

Contacts, organisations and the tags that label them, with an idempotent upsert API other modules and a venture’s own code can call. An upsert is idempotent by the key a caller names, so replaying a webhook or a sync run twice lands on the same row rather than a second one. Use it for the records a venture keeps about its customers; module-orgs is for the records it keeps about itself.

From the crate’s own README.
