There shouldnt be any issues. As @JohnLeonard said though - you do have to make sure that Instadocs is installed after Job Ops due to the panel changes. Instadocs adds a tab in most screens and while our installers merge panels together, Job Ops just overwrites panels. So if Job Ops gets installed after Instadocs it just wipes out the standard panel. If Instadocs is installed after Job Ops our panels will be merged with theirs.
