A budget consists of one or more versions and each modification of the budget is part of a version.
Compare the versions of a budget with each other to visually detect differences between the versions.
For each budgeted amount you can visualize the history: what amount was inputted by who and when.
You can create predefined budget schemas (structures) which can then be applied to multiple budgets.
Define transformation rules to 'translate' one schema to another, view a budget inputted in one schema visualized into another schema.
Generate comprehensive budget analysis reports for a single budget version, or for all budgets of a project, as an MS Excel pivot table.
