You can track the hours entered on a project phase by importing a budget to that phase. Assign a budget to the project from the Projects > Budget tab or the Budget Templates screen. To track hours against the budget, run a Project Time Entries report or check the Project Status widget.
In addition, CORE can notify you when spending approaches or exceeds the budget. From Projects > Project Center > Settings > Monitoring, enable the Approved Spent against Budget alert and set a threshold percentage, for example, 75%. CORE then sends an in-app notification, an email, or both, to the recipients you choose once approved spending reaches that threshold. Click Additional Threshold to set up notifications at multiple milestones (e.g., 25%, 45%, 75%, 80%).
