Duplicate company records happen when two team members create the same record from different email domains, or when an import adds a record that already exists with a slightly different name.
Detection
Data > Merge Duplicates > Companies tab. The dedup engine groups likely duplicates by exact domain match, similar name, and shared contact overlap.
Resolution
The merge UI shows both candidates side by side. For every conflicting field (different revenue, different industry, different address), pick which value wins. You can mix and match — keep one record's domain and the other's address.
What carries over
All linked contacts from both records, all deals, all activities, all files, all custom field values you picked, and the union of all tags.
Permanence
Merging is irreversible. Tormano writes an audit log entry for every merge so you can see what was combined, but there is no automatic unmerge. Review carefully before confirming.
