I haven’t received any confirmation that I’m registered for the conference. Can I arrive to Warsaw without any fear?

The electronic ticket, that you problably received on your e-mail inbox, is the confirmation of participation in the event. If you lost it, don’t panic – we’ll send tickets to all Attendees the few days before the event. Even if you were absent at the list of attendees, you would take part in the event after quick payment at the service desk.

When will my company receive a paper invoice?

According to point IV.4 of the Regulations available at registration system, we don’t send paper invoices. According to Polish law, unsigned invoice has the same importance as signed – thus, in order to get paper invoice, it’s enough to print the electronic version of it.

I can’t go to the event, but there’s a person who would like to attend the event instead of me. What should we do?

Please log in to your account in registration system and click the “Edit registration” button. Make all necessary changes, next click “Save” and confirm. Both you and new Partcipant will receive the e-mail confirmation. Prepare the following information:

Sure! As soon as you register and pay for your participation in the conference, contact us and we will prepare a visa invitation letter for you. After registration and payment, please contact us for your visa invitation letter. We will need your full name, date of birth, nationality and passport number.

My company is VAT registered in EU. Do I have to pay VAT on my registration?

Since the place of service delivery is in Poland, we have to charge VAT on top of the net amount and the “reverse charge” scheme does not apply in this case (it’s different from export of services or goods to another EU country).
