VAT and Tax Calculation for Quotes and Invoices in Enterprise Edition and Project Operations

[Grandfit]

I am wondering what the best practice for handling VAT on quotes and invoices is. Is it really the case that there is no standard feature for adding VAT/Tax on your quotes or invoices? I mean, what's the point in creating a quote if you can't even set a standard VAT rate that is applied to products, line items and grand total? Or am I missing something?
