Remove Duplicates from Professional Services Firm Data
✓ TestedWorks with CSV, Excel, Google Sheets → JSON-LD Schema

Professional services firms -- consulting, accounting, architecture, engineering -- manage client and project data across CRM systems, time-tracking platforms, billing software, and proposal databases. The same client organization can appear as 'Deloitte', 'Deloitte Consulting LLP', and 'Deloitte & Touche' in different systems. When partners bring clients from previous firms or projects span multiple engagements, duplicate records proliferate. dataclean.to matches client, contact, and project records by organization name, contact details, and engagement history to produce a unified business development database.
The Problem
Duplicate records in professional services data undermine business development, billing accuracy, and client relationship management. A CRM with three entries for the same client organization shows conflicting revenue history, making it impossible to identify your top accounts by actual total billings. Time entries logged against the wrong duplicate project record produce incorrect client invoices that damage the firm's credibility. Business development teams pursuing a prospect who is already an active client under a different record create an embarrassing situation. Cross-selling opportunities are missed when the firm does not realize its tax client is the same entity as its consulting client listed under a different name variation.

How to Fix It
1
Export client and project records
Pull data from your CRM, time-tracking system, billing software, and proposal database into CSV format. Include client organization name, primary contact, contact email, project name, engagement type, billing amount, and responsible partner.
2
Upload to dataclean.to
Upload the combined CSV. The tool compares organization names, contact emails, and project details to identify clients and contacts that appear in multiple records across your systems.
3
Review duplicate client and contact clusters
Examine flagged groups. Common patterns include the same organization with and without legal suffixes, contacts listed under both employer and personal email addresses, and clients entered separately by different partners who both have relationships.
4
Consolidate into unified client profiles
Merge confirmed duplicates into single client records. Combine total billings history, preserve all contact names and relationships, link all associated projects, and retain the earliest engagement date.
5
Export the clean business database
Download the deduplicated data for import into your CRM and billing systems. Unified client profiles enable accurate revenue reporting, prevent duplicate solicitation, and surface cross-selling opportunities.
Frequently Asked Questions
How does the tool handle subsidiaries of the same parent company?
Subsidiaries sharing a parent company name are flagged based on name similarity and address proximity. You decide whether to merge them into one client record or keep them as separate entities linked to a parent, depending on how your firm structures client relationships.
Can it detect when two partners have entered the same client independently?
Yes. When two records for the same organization have different responsible partners assigned, both entries are flagged as duplicates. This reveals situations where multiple partners have relationships with the same client, enabling coordination rather than competition.
What about clients who were prospects that later became active clients?
A prospect record and an active client record for the same organization are flagged as duplicates. Merging them preserves the full relationship timeline from initial business development through active engagement.
