We do not add, edit or change the content of your document. There is one exception: we add your order reference number to the back cover.
We need the order reference number to match your order within our systems. The order reference number is also used for re-ordering and customer service purposes, appreciated by many of our customers.
The order reference number is placed at the right-hand side near the bottom of the final page. So when you prepare your document make sure you don't put any importan content in this area because it may get partially obscured.
