Expenses document allows to register expenses, which are accounted when calculating your monthly results. You may specify expense type and then generate a chart of expenses.
For future reporting matters, you can specify tax amount, payee (entered manually) and notes.
Any expense can be linked with some project or job, which adds additional slice for future analysis of your projects.
If expense must be distributed between a number of months, than you may do it using corresponding field. In this case, amount will be evenly divided between specified number of months and respectively included to the expenses of each month. Examples of expenses:
Internet connection - 10 USD (1 month)
CAT tool license - 500 USD (12 months, cause we may expect license updating after 1 year)
Taxes - 100 USD (3 months, if pay taxes quarterly)
