A service guarantee is a marketing tool service firms have increasingly been using to reduce consumer risk perceptions, signal quality, differentiate a service offering, and to institutionalize and professionalize their internal management of customer complaint and service recovery. By delivering service guarantees, companies entitle customers with one or more forms of compensation, namely easy-to-claim replacement, refund or credit, under the circumstances of service delivery failure. Conditions are often put on these compensations; however, some companies provide them unconditionally.
