Issuing certified electronic invoice

There is a possibility to issue certified electronic invoice in CO3. These invoices not require printing, are transmitted electronically and stored electronically. Certified electronic invoices are signed with CO3 Kft.'s own enhanced security certificate, and receive a time stamp from a qualified service provider. The certificate is a certified certificate used for electronic signatrure and encryption. A timestamp proves the existence of any electronically stored information at a moment. The electronic signature and time stamp of the invoices can be used for a separate unit price fee. The unit price of the timestamp varies per subscription plan.

You can see your current timestamp balance at the top of the Finance tab:

You can choose to top up your balance by clicking 'Top up.':

Here you can set how much you want to top up your balance. The system allows payment by card and bank transfer also. You can provide an electronic signature and timestamp to your invoice by selecting one of the electronic methods at the bottom of the invoice when recording:

  • Print invoice to PDF or
  • Send e-invoce to customer If one of the above options is selected, "E-signature and timestamp" will be active.

By selecting this, the invoice will be prepared by including CO3 Kft.'s own enhanced security certificate and the time stamp from the qualified service provider.After the invoice is issued, the time stamp balance is reduced by the unit price of the time stamp.

Invoices with an electronic signature and time stamp are automatically stored in the Documents module after they are issued or emailed. The original PDF documents of the signed invoices can be retrieved, accessed and downloaded from the Document module at any time.

Can I send an e-invoice to multiple recipients? Yes, you can. Enter email addresses separatedly in the email address field by commas, when finalizing your invoice.

Certified electronic invoicing has a legal background. Please contact with your accountant to know more about it.
