work flow

Can anyone recommend any good pre press (pre-flight) software? In the past we've checked each upload from our clients before going to print, however we need something more automated that can handle batch jobs also. The majority of our uploads are pdf so it'd need to support this format before...

Hi - we are a small-med size sign/large format printing company. We are looking for a "simple" print management/job tracking system (prefferably web-based) that we can integrate with our website to manage jobs/work flow. Any suggestions would be appreciated! Thanks.
