Creating Invoices, from the TimeSpent reports

Please could somebody assist me. I am trying to create some invoices, from the timespent reports, and I am coming up against several roadblocks. I am hoping someone may be able to explain how they do it, so I can get some ideas... :)

This is how I am trying it currrently:

I run the timespent report by account, to get a list of the completed jobs, assigned to the accounts. I have been able to get the different accounts to appear on their own, seemingly, pages. However, the heading with most of the details of the report only appears in the first page, so only the client at the top of this list, gets to understand which company is providing the report, and the details of it, ie date frame etc.

I still can't split the report, so I can email separate pdf's to my clients, to accompany the invoices... :(

Also, how do you know which tickets have been invoiced, and which haven't? You can't really just run the report over a month at a time, because there are invariably some jobs which are not completed in those months - so how do you know what you have billed?

Am I expecting too much from this system - is it not tailored for incorporating a billing system into the package? IF so - why include the time spent details?

I have Quickbooks, not sure if anyone out there uses an integration module or similar?

OR do I need a separate "TimeSheets" application that can interface with SCP?

Any help will be SINCERELY appreciated, as my billing has really fallen behind because of this, and now is not the time to interrupt cash flow...

Thanks,
Ryan
