Accounting documents with a guaranteed electronic signature


As of today, all accounting documents in PDF format have a guaranteed electronic signature

We send all accounting documents to our customers automatically after they are issued by e-mail (to the customer’s address on the order/service). All documents are also available for download in the WEDOS Customer Centre in the Invoicing section.

The customer will receive the following messages and related documents for each order:

  • a call for payment (advance invoice with payment instructions)
  • tax receipt for the payment made
  • Invoice (statement of services provided)

We recommend our customers to use a credit – deposit account. The advance account is used for bulk payment of service orders and their extension. The customer does not have to make individual payment orders all the time and at the same time it reduces the number of all accounting documents sent.

All accounting documents are in PDF format and have a guaranteed electronic signature. A qualified system certificate issued by the PostSignum certification authority is used. This means that this electronic signature is also accepted by Czech state authorities and organisations.

If your PDF viewer does not trust this certificate authority, you can download their certificates from

We do not send paper documents by post. A guaranteed electronic signature issued by an accredited certification service provider is a sufficiently conclusive form of authenticity and origin of the accounting document and is fully compliant with the Value Added Tax Act and the Accounting Act.
