Donor data cleanup for nonprofits

Consolidate donor records from giving tools, events, and spreadsheets, resolve duplicates, and build reliable reports on giving and retention.

Donor data accumulates across giving platforms, event tools, email lists, and spreadsheets. Duplicates lead to double acknowledgments or missed thank-yous, and reports on giving and retention cannot be trusted.

We consolidate donor data, resolve duplicates with clear matching rules, respect communication preferences, and reconcile totals with financial records. Reports then show giving, retention, and campaign results from one source of truth. Clean data also makes the next donor system or website launch much simpler.

Things to keep in mind

  • Carry over the most restrictive communication preference when merging.
  • Keep a log of merges so they can be reviewed.
  • Clean data before launching a new website or donor system.
