1 · One source of truth
A single client record carries contacts, entity type, year end and relationships.
Product · Run the work
One client record every part of the system reads from — contacts, groups, entities and a timeline of what actually happened.
What you can do
Contacts, groups, entities and a full history live on one record that billing, work and documents all read from — so nothing is right in one place and stale in another.
Clients, projects, billing and documents all read the same record.
Contacts that cascade through a group, with related entities linked.
Everything about a client — work, money, documents, comms — on one screen.
Entity type and year end that drive the work cadence.
What happened, logged as it happened, not reconstructed later.
Staff discuss a client in context, saved to the record.
