When javascript is disabled, does a visit register goal completion in Google Analytics?

I'm looking for reasons why Google Analytics goal completions would appear to be fewer than the actual known number of online sales for a company, and I'm wondering if disabled javascript is likely to be the primary cause of a discrepancy.  Thanks for any insight you have.

To add another reason that this is possible:

GA Goals only count once per session. So in the event that someone purchases twice in one session, that goal will only have registered once.

Disabled javascript should not account for more than around 2% of lost conversion stats.

Check to make sure that the conversion page is loading quickly too, and that people aren't clicking a prominent link that takes them off of the page before the page has completely finished loading or it might not register the conversion.

If people have javascript turned off then they don't trigger a view so no goal is registered.

There could be other reasons. Check your funnel, namely the page before the Goal conversion page and view navigation summary (content >site content >all pages then search for the page url). Check to see if everyone is going to the URL that your using for the goal and not a strange variation generated by your site. If there is a variation  include it in the goal and make sure analytics is installed on it.

Edit: I've also seen cases when orders are processed through the website over the phone by a representative but the I.P address of the office is blocked. So you see the sale as online but that isn't tracked in analytics because of the I.P block. In those cases I would suggest setting up a new profile with a filter to include that I.P only or one to not exclude internal traffic.

Hope that helps
