Im a beginner user of SUGARcrm, and would like to ask a few questions about it:

Is it possible to create and store invoices, if yes, how?
Would be useful to have a kind of registration for in/outgoing post, anything like this available?
Is it possible to mass-upload documents? e.g. to archive old invoicing
I couldn't find in the calendar the choice of booking holidays, sickness, absence for the employees?

we have the sugar community edition version 5.0.0d (build 3235)

thanks for answering in advance
