I am an attorney and I bill clients on a regular basis (monthly), not at the end of a project.

Having worked out the issue of billing for multiple attorneys on one project, I have a suggestion for streamlining the invoicing project.

Currently, you select the project in Billings, then select a range of slips/expenses to include, then generate the invoice using "send invoice".

It would be very useful to have a command that would allow me to batch generate invoices for all clients with projects that have unbilled activity during a particular period.

For example, I would enter the date range in a dialog (for example, a month) then be presented a list of all clients with active projects that have unbilled time during that period.

From that list I could choose which clients/projects to bill. If there were slips that I did not want to bill, I should be able to designate them as nonbillable.

Then, after making my selections, billings would batch generate the invoices and present me with a list of the invoices that it generated. From the list, I should be able to select an invoice, view it and decide whether it should be printed or cancelled.

This would be tremendously helpful, particuarly when managing many projects that have ongoing billing needs.
