Final answer:
Customer self service (CSS) software is designed to enable customers to complete inquiries and perform tasks without needing help from the organization's employees, unlike CRM, SFA, or SCM software which serve different business functions.
Step-by-step explanation:
The type of software that allows an organization's customers to complete inquiries without the aid of the organization's employees is known as customer self service (CSS) software. This kind of software provides users with the tools and information necessary to resolve their own issues and perform tasks that otherwise would require assistance. For example, this can include managing account information, making payments, or seeking answers to frequently asked questions. While customer relationship management (CRM) software focuses on managing the company's interactions with customers and clients, and sales force automation (SFA) software is used to streamline the sales process, CSS is specifically designed to empower customers to help themselves. Moreover, supply chain management (SCM) software is intended to manage the flow of goods and services.
Software such as database user interface and query software, for instance Microsoft Access, and commonly used office suite software like Microsoft Office, may be parts of or interact with various kinds of business software, but they are not specifically tailored for customer self-service purposes.
