SIGNIFICANT CLIENTS AND OTHER CONCENTRATIONS [Abstract]
SIGNIFICANT CLIENTS AND OTHER CONCENTRATIONS	(4)SIGNIFICANT CLIENTS AND OTHER CONCENTRATIONS The Company had no clients that contributed in excess of 10% of total revenue for the nine months ended September 30, 2018. The Company does have clients with revenue exceeding $100 million annually and the loss of one or more of these clients could have a material adverse effect on the Company’s business, operating results, or financial condition. To limit the Company’s credit risk with its clients, management performs periodic credit evaluations, maintains allowances for uncollectible accounts and may require pre-payment for services from certain clients. Based on currently available information, management does not believe significant credit risk existed as of September 30, 2018. On October 15, 2018, Sears Holding Corporation (“Sears”) announced that it has filed a petition for bankruptcy protection in the United States Bankruptcy Court for the Southern District of New York. As of the date of filing, TTEC had approximately $3 million in pre-petition accounts receivables exposure related to Sears. TTEC continues to provide services to Sears and has received assurances that the cost of its services will be covered by funds that Sears has available to satisfy its obligations to its current service providers through debtor in possession financing.

The entire disclosure for claims held for amounts due a entity, excluding financing receivables. Examples include, but are not limited to, trade accounts receivables, notes receivables, loans receivables. Includes disclosure for allowance for credit losses.
