The Expenses section allows you to keep track of your business related expenses. You can add new expenses and also separate your expenses into Expense Type categories if this is useful for you. The running total cost of your expenses for the current financial year is shown and the running total for your mileage can also be seen, unless you have opted out of mileage in the Business Settings. You can opt in to the mileage function again if you wish to, via Business Settings. Tip: A summary of your Expenses, sorted into financial years, can also be found in the Reports section, in Financial Details.
