Working with Invoice files
TimeCache keeps invoices in a different file than the TimeCache data file. You must have an invoice file open before TimeCache lets you work with invoices. Any time you save an invoice created with TimeCache, it is saved to the currently open invoice file.

Invoice files can be created, opened and closed with commands in the File menu; New Invoice File, Open Invoice File, and Close Invoice File, respectively.

You can also access these functions from the popup menu that appears when you click the invoice icon in the toolbar. The popup menu also allows you to open the Invoices panel.

The toolbar Invoice icon also serves as a visual cue as to whether there is an invoice file open. The icon is grayed out when there is no invoice file open, and is the same green color as an invoice file's Finder icon when there is an invoice file open.

Once you open an invoice file, TimeCache remembers it and automatically reopens the invoice file anytime you open a TimeCache data file. You can make TimeCache "forget" the invoice file by closing the invoice file (choose File>Close Invoice File).
