Add cost management

Hope to see adding cost management is available in invoiceplane.

Invoiceplane gives strong help in managing invoices for my small business but it will be better if there is function to manage cost. Such as managing the payees, pay date, amount (inc. or not inc.GST), payment method, and certainly a report / filter to check the total cost in a certain period of time will be great (for taxation purpose).

Understand that it is not a simple task but this should make invoiceplane as an all-in-one app (managing both income and outcome well) for small business.

Thank you.
