Customer service with issue tracking has similar functionality to Sales module, but instead of creating target group of clients and then work with them here we are creating a categories of issues from clients and adding a client's issue when it will be received. Module bases on processes, each type of client's issue can have different process used to standarize service of a client.
Filtering of issues allow quickly find unfinished issues.
Creating a new issue is very simple: we are just selecting client, type of an issue and entering name. System based on type of an issue select proper process and assign work to dedicated persons.
Work with an issue is simple with issue card where you can get history of performed steps, possible next steps to do and list of attached files.
