What type of charges cover support for software after purchase?

Maintenance charges refer to the costs associated with the ongoing support and upkeep of software after its initial purchase. This usually includes services such as troubleshooting, updates, bug fixes, and technical support, ensuring the software continues to operate effectively over time. These charges are crucial for users who rely on software for critical operations, as they help maintain its functionality and can enhance security by keeping the software updated against vulnerabilities.

In contrast, installation fees typically cover the costs related to setting up the software for the first time, while service fees may refer to general support services that aren't specifically designated for ongoing software maintenance. Upgrade costs, on the other hand, are tied to improvements or new versions of the software, not the continual support necessary after the initial purchase. Thus, maintenance charges are the key to sustained software functionality post-purchase.
