Budgeteer is a budget monitoring tool that allows you to track project budgets. A project in the sense of Budgeteer contains a set of budgets each defined in a currency. For each person that contributes to the project, you set up a daily rate in that currency. Budgeteer allows you to import working hours and does the math for you, so that you always know where your budgets are heading.
