Which term best describes the fees for ongoing assistance with software?

The term that best describes the fees for ongoing assistance with software is maintenance charges. These fees typically encompass a variety of services related to keeping the software operational, which can include troubleshooting issues, providing updates, and ensuring the system continues to function correctly over time. Maintenance charges are associated with the long-term sustainability and performance of the software, making them essential for organizations that depend on these tools.

Consultation fees, while related to expert advice or guidance on software issues, don't specifically pertain to the ongoing nature of assistance. Support fees could also describe some aspects of ongoing help but may not fully encapsulate all the ongoing responsibilities associated with keeping the software functional, which is what maintenance charges intend to cover. Update costs refer strictly to the expenses incurred when new versions or features are released, rather than the broader scope of assistance needed throughout the software's lifecycle.
