Discussion forums are a useful way of providing support to your hosting customers. I believe they support forums should compliment an email ticket support system, not replace them.
They provide a place where members can discuss issues not directly related to their account. For example, general advice on website hosting, website development questions, marketing etc.
Discussion forums are also a useful way for potential customers to ask questions in a pre-sales discussion room.
bbPress is a simplistic forum solution that requires you to add a lot of additional plugins to add forum functionality which is standard on other forum applications.
In my opinion, bbPress is way too basic to be used as a support forum, however you may want to consider using it if the front-end of your hosting company is powered by WordPress (*bbPress is a WordPress plugin).

phpBB was once the most popular forum application on the internet. This was in part due to it being free at a time when better alternatives were premium. It continues to have a large devoted following to this day and is still free to download.
You will find thousands of themes and plugins available for phpBB, which is why many hosting companies decide to use it for their support forums.
Simple Machines Forum (SMF) is a powerful free forum application that is fast and easy to use. It is an application I still have a lot of fondness for because I used it for a few communities I used to run.
I highly recommend you check SMF out if you are looking for a good free forum solution.

Launched in 1999, vBulletin was the leading online forum software for many years. I used them to build communities from 2001 to 2010.
The fifth version of the software retails at $249 with their mobile suite application costing a further $150. For that price you get a feature-packed piece of software that has everything you can think of. Blogs, polls, user permissions, and an advanced admin panel.
If you prefer, vBulletin can host your community with their vBulletin Cloud service. Plans start from $19.95 per month for 25GB of bandwidth and prices increase with usage.
Xenforo was developed by the lead developers of the most successful period of vBulletin's life. When vBulletin was bought over, the developers formed their own forum software company called Xenforo.

A license for Xenforo costs $140. Extensions are available for an additional fee, such as their media gallery and resource manager.
