I'm looking to be able to print batch pdf invoices on letterhead. I want the normal operation to function which uses the file invoicepdf.tpl in which I will have a logo and header info.
Then maybe a second Batch PDF export menu item or button that would simply load a second version of invoicepdf.tpl with a blank space to accommodate the letterhead artwork.
Can someone point me in the right direction -- I'm brand new to WHMCS.
