Does anyone use software like this? I would be interested in comparing a few packages. I am looking for a package that: - will allow me to track projects with multiple sub-contractors - issue work orders and invoices - allow me to organise and link files/documents to certain projects (all my work is based around the movement of Word documents!) - potentially have a web interface so customers can log in and track their projects etc. - is fairly customisable, so unique fields and types of data can be used specific to my industry - is free Well, it doesn't have to be, but it would help! I had a quick look at http://www.project-open.org/ - any experience of that? Any other suggestions?
