FFLGuard is a company that specializes in Legal Services & Compliance Solutions
for the Firearms Industry.  One of their departments monitors outputs from the BATFE and puts out advisories, and the most recent is the end of year report from BATFE inspections.

The BATFE actually publishes this information as a Power Point presentation that you can access here: http://www.atf.gov/sites/default/files/assets/Firearms/FirearmsIndustry/2014_shot_show_stats.pptx

I’m a data nerd so I found the presentation interesting.

The quick summary:

• Overall licensee population has increased (the majority of the increase was in dealer licenses).
• The number of new applications (for licensees) denied is high at close to 20%. [edited]
• The most frequent violation is transferees not properly completing ATF Form 4473, Section A.
• The second most frequent violation was failure to timely record information in the A&D Record (which is mainly related to poor inventory control).  The scary thing is that even after audits, 14,455 firearms remained missing (which is actually slightly down from last year, but way up from 2012).  There are gross numbers, not the trend (which as was pointed out by David in the comments is moving in a positive direction). [edited]

I think the take away is that if you are going to interact with the BATFE in an official capacity, try and have your documentation in order and follow the rules.
