What does the budget balance indicate at the end of a project?

The budget balance at the end of a project reflects the remaining funds available for project completion. This is crucial for project management as it demonstrates whether the project has sufficient funds to cover any final expenses or if additional resources may need to be secured. A positive budget balance indicates that there are extra funds available, while a negative balance signifies that expenses have exceeded the allocated budget.

The other choices do not provide a comprehensive view of what the budget balance signifies. Total expenses incurred focuses only on the costs, ignoring the funds available. Funding sources yet to be received pertains to anticipated income rather than actual available resources for wrapping up the project. Overall project profitability ties into financial outcomes but is not directly indicated by the budget balance itself, as that balance specifically shows liquidity and available funds instead of profit margins.
