Two company groups, each listing the spellings that belong to it.

See the company behind the spelling

Acme Inc and Acme Incorporated and ACME INC are one customer. A sort puts them rows apart. A count of accounts is off by a third.

This tool strips legal suffixes and punctuation and groups the variants.

Merge the company records too

A grouped spreadsheet still leaves three account records in the CRM. Deals and contacts hang off each one. Reporting splits three ways.

Dedupely merges duplicate companies inside your CRM and keeps their deals and contacts together.

Three duplicate company records with their contact and deal counts, merged into one Zephyrion BioTech with 19 contacts and 7 deals.
