The "Cost Categories" screen registers and changes cost categories for project budgets. A cost category is a category in which costs or revenues are registered, such as "purchase ground", "architect" or "sale houses". All financial activities within a project are distributed over cost categories. All registered projects can use the same cost category. A cost category belongs to exactly one roll up, which groups the linked cost categories (see also [[Invantive Estate/Subjects/Administration/Roll Ups|Roll Ups]]). Roll ups belong to master roll ups, which show an even more general view of the cost categories (see also [[Invantive Estate/Subjects/Advanced/Master Roll Ups|Master Roll Ups]]). The cost category structure for real estate projects is often based on the Dutch standard NEN 2631. The screen contains the following fields: - "Master Roll Up": The master roll up to which the selected roll up belongs. - "Roll Up": The roll up to which the cost category belongs. - "Code": The code of the cost category. - "Description": The description of the cost category. - "Explanation": Free text. - "Payment Term (days)": The number of days within which an invoice must be paid. This applies to invoices in this cost category that have no due date or have not been received yet. The value is used for [[Invantive Estate/Subjects/Budget Control/Cash Flow Projections|Cash Flow Projections]]. - "Interest": The cost category is treated as interest if this box is checked. - "Investment Real Estate": The cost category is treated as investment property if this box is checked. - "Fees": The cost category is treated as developer costs if this box is checked. - "Provision": The cost category is treated as a provision if this box is checked. - "Ground": The cost category is treated as acquisition costs for land if this box is checked. - "Unexpected": The cost category is treated as a reserve for contingencies if this box is checked. - "General Costs": The cost category is treated as general expenses if this box is checked. - "Own Capital": The cost category is treated as owner's capital if this box is checked. - "Hours": The cost category is treated as a reserve for contingencies if this box is checked. - "Distribution Method": The way cash flows are allocated for this cost category if this is not set at a more detailed level.
