Abstract— The quality of information systems is the key
to user satisfaction with an information system application.
This study uses the information system success model as a
theoretical basis for discussing the influence of information
system quality on the sustainability of using Information
System applications. Qlue is used as a case study as one of
the complaint service applications. This study uses a
questionnaire with 299 data collected using Google Forms
which are distributed through various social media. Then
to test the hypothesis, the data isprocessed by Partial Least
Square (PLS) using SmartPLS application. The results of
this study explain that the factors influencing the intention
to continue using Qlue are satisfaction with system quality
and information quality, including design aesthetic,
immediacy, and customization.
