Duplicate Detection
Keep your database clean automatically
Duplicate Detection uses multi-stage scanning to find and merge duplicate records before they cause problems. The system first scans by username and email for exact matches, then broadens to title field matching for near-duplicates. Potential duplicates are grouped for review, and merging consolidates all donation history, sponsorships, messages, and activity into a single clean record.

The Problem
Without duplicate detection, your donor database accumulates redundant records over time -- splitting giving history across profiles, inflating donor counts, and leading to embarrassing duplicate solicitations.
The Solution
With Gratona Duplicate Detection, staff can review likely matches and use a guided merge workflow. Confirm the records and relationships included in a merge before applying it to production data.

How it works
Automated scan
The system runs multi-stage duplicate scanning -- first matching on username and email, then broadening to name and title fields for near-duplicates.
Group review
Potential duplicates are grouped together with a side-by-side comparison showing each record's data, giving history, and activity.
Select primary record
Choose which record to keep as the primary. The system shows you exactly what data will be merged and what will be discarded.
Merge with history
Review the donation, sponsorship, message, activity, and profile data included in the supported merge path before selecting the primary record.
