Propstack GmbH · Broker CRM & migration · In preparation
Modern broker CRM with a strong API.
How it connects
API-based sync of contacts and deals — or a clean one-time migration.
For a switch we run a guided import: you get a mapping preview before anything is written, and the old system stays untouched. For parallel operation, a scheduled sync keeps both sides current.
Typical data flows
- One-time migration: objects, contacts, activities, documents
- Or a running sync while both systems stay in use
- Duplicates are detected and merged on import
