Great program! However I am having some problems with VAT (Netherlands BTW) on the invoice (21% BTW) and it also wont show the amount of VAT on my summary.I like to keep track of all these things 
and its also a ditch requirement to show it on invoices. Can anyone help me out correcting the settings?
There are many built-in Netherlands tax codes for various percentages, EU and non-EU, etc. Have you read the Guides on tax codes? Once you have, ask specific questions beyond “having some problems.” Amount you owe will be in Tax payable. The various reports will break things down. Once you ask detailed questions, there are several very helpful Dutch forum members, especially @Hennie.
