When requesting the certification of an invoice and/or a packing list please ensure the following criteria is met and that you understand the process;
The invoice and/or packing list is signed by someone who appears on your company's current Formal Undertaking, held on our files.
Ensure the signature matches the sample on the Formal Undertaking.
We will only stamp the page that bears a signature. If it is a multiple page invoice with each page signed, we will stamp the page that holds the total invoice amount.
