We strongly recommend that all customers use a credit card to pay for premium services. It has many benefits:

Some customers, such as companies, schools or nonprofit organizations might not be able to pay direclty with a credit card, and for these we may issue a proforma invoice at their request. Private customers are also able to request a proforma invoice if it is necessary. 

The proforma invoice can only be issued:

  • on request - contact our customer service directly,

  • to ANNUAL / BI-ANNUAL premium plans - STANDARD, ELITE or Survio BUSINESS,

  • in the currencies EUR and CZK. We are unfortunately unable to process proforma invoices in other currencies than these. 

Warning: This purchase is a manual process so it may take several days before you have the premium services available! Our customer care team is unable to speed up this process. 

Recommendation: If you need to activate premium services immediately, please pay directly with your payment card or PayPal through our payment processor cleverbridge AG.
