| A qualified electronic signature is an electronic signature that ensures the integrity of invoice content and confirms the invoice issuer's identity. Due to legal requirements, we include a qualified electronic signature on all PDF invoices to customers who indicate a billing address within the European Union.
If you receive a PDF invoice with a qualified electronic signature after you have completed your order, you can use a separate program to verify the qualified electronic signature and create a test log. For example, you can download the digiSeal reader application free of charge, install the program, save the PDF invoice on your computer or other system and open the file using the digiSeal reader. The signed invoice and the test log are used for submission to the tax authorities in the European Union. |
