Yes, it is possible with our Extended version.

I have the same questing and the productslist in the products manager is completly empty do i have to import the products or so?

you can import those products directly into an invoice. if you install the plugin, then when you search through products INSIDE an invoice, virtuemart results will show up (therefore there's no need for them to be imported into the product list, this would only cause duplicities)

Oke i understand but this doesn't seems to work

I have activated the plugin "Invoice Manager - Search Items - VirtueMart" and go to the Invoice manager, click on "New" and go to the tab "Items", click on "add new item" and when i type a value somewhere noting happens

I Use Joomla 3.3.6 with VM 3.0.0

no, the place where to type to "search" is just beneath this, where there is a search box with a Search button

been there, done that and doesn't work, no results are shown

hmm.. should be working. if you want to send me admin access at support@ joomlathat.com I'll take a look at it.

I've send you an email

Did you had the time to look at this issue jet?

The problem was related to the language. you had set in the plugin details that the language had to be "nl_NL" but actually in your virtuemart tables it still is "en_gb". so I let it to en_gb and now the products show fine...

Thanks for this solution!
