In InvoiceOcean you have to possibility to categorize income and expenses. To begin with, it is necessary to add your own categories. To do this:

• go to Settings> Categories of income/expenses
• press the blue New button
• name and (alternatively) describe the category
• press Save

From now on it is possible to assign categories to products and invoices and generate reports only for selected categories. To assign a category to a given invoice, when creating or editing a document, select a convenient option under Category.
