Two-Way Sync

Two-way sync means changes in either system update the other. Example: update a contact in your CRM and it updates your email marketing tool, and vice versa. It sounds great, but it can cause conflicts if both systems change the same data differently. Two-way sync needs rules: which fields sync, which system wins conflicts, and what happens with deletes. When done carefully, it reduces duplicates. When done poorly, it multiplies chaos.
