I know we have quite a few consultants in the Ruby world. Does anyone
have a nice system for generating billable invoices, possibly
Rails-based, which generates PDF or something of that nature?
Something they would be willing to share (or already do.) This sure
would be nice :)

Also something for tracking time which could be tied into the above
would also be great.

Even if it isn't Rails-based, something automated in Ruby would be
useful, and PDF sounds like the perfect output format for an invoice.

If the above does not exist, I will be surprised, and maybe I should write it.

Of course if there is some other non-Ruby system which works great for
this, I wouldn't complain, but Ruby would be nice of course.

Thanks,
Ryan
