ExisEcho uses sophisticated fuzzy logic algorithms to remove duplicates from a wide variety of data sources. Use ExisEcho to find misspelled duplicates called "fuzzy matches" in your customer masters, contact lists. Use ExisEcho to dedupe data in your transactions such as vendor payments. Masterfile duplicates can cause a lot of errors in your business, costing you thousands of dollars in lost revenue due to mistakes.

Even if you find just one error worth a $1000 this software will have paid for itself! Our product has many advantages over our competition. The more fuzzy matches you find, the more money you could potentially save. We use proprietary algorithms to discover inexact matches/fuzzy matches that are very difficult for other fuzzy logic applications to locate, such as when you have “John Smith” and “Smith John”. No other fuzzy logic applications software can claim this kind of functionality to discover fuzzy matches! Other fuzzy logic applications will not give you sophisticated options such as batch processing. Try it, and we are confident that you will immediately realize the benefits of this fuzzy logic application.
The terminology that is used a lot in this field is interchangeable. For example fuzzy dupes, or fuzzy duplicates are terms often used with inexact matching algorithms that use various approaches, such as the levenshtein distance approach and other methods.
