How to add custom header fields
You can add fields with your own text to the header of any TimeCache report layout. To add a field, show a report and enter layout editing mode. Then choose Report>Add Header Field...or Invoice>Add Header Field..., depending on whether you're working with a report or invoice. In the dialog box that appears, type the text that you want to appear in the field, then click OK. The field appears at a default position within the report header. You may need to move it to a different location. Note that this results in adding what TimeCache considers a text block to your layout.

You can change a custom header field's font size and style by Control-clicking the field as explained in How to change report fonts.

You can resize the custom header field as explained in How to resize a custom object.
