I think a chat widget on your site is a convenient way to offer support that works for a single-person company or a dedicated support team. We use Zopim on our site. It's the only way that I know of were one support person can offer real-time help to multiple customers at the same time. (or at least give that perception as long as not too many people are chatting at once). Having a knowledge base and/or documentation is a great because a lot of people do prefer to help themselves. That cuts down on the volume of support calls too, so it's an easy win. I personally think that support and sales go hand-in-hand so, especially when you're getting started, you need your customer's support experience to be excellent.
