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 take part in 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:

– email address
– T-shirt size
– participation in conference party (no/alone/with accompanying person)
– current job position
– job experience

I haven’t received a verification email. What should I do?

Please check Spam folder, next verify anti-spam settings of your inbox. If you didn’t find an email, try new registration using another e-mail address.

What is this conference about?

JOIN! 2020 is conference dedicated to SQL Platform. The SQL Platform conference is specifically designed for: – programmers and database administrators – software engineers – architects and designers of database systems

In what language will the sessions (workshops) be presented?

The official event language is English. All workshops will be presented in English.

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). You can, however, reclaim the paid VAT from Polish tax authorities under EU VAT return scheme. More on that here: http://europa.eu/youreurope/business/vat-customs/refund/index_en.htm.

Can I pay by credit card?

You can pay by credit card via PayPal. During registration please choose PayPal as your payment method and send your payment via PayPal to the e-mail address indicated on your proforma invoice.

How can I participate in conference?

Workshops will take place on some video streaming platform. If you had registered, you will receive an email with links, that allows you to enter the session room.

Can I send my conference links to my colleagues?

Links will work only for one person, so if your colleagues would want to participate in event, they should register and they will receive their own links.
