On Collectionstock, it is the Studio who sells the design and who selects the selling price in USD.
In theory, it is the Studio who is paying Collectionstock a commission for using the platform. Collectionstock transfers its Studios an amount per design sold calculated as follows: the amount is the difference between the selling price selected by the Studio and the commission due to Collectionstock. The amount transferred to Studio is called the Studio Fee, and is transferred within 45 days of a design being sold. Studio will receive the Studio Fee in USD.
When registering as a Studio, Collectionstock will ask the Creators PayPal account in order to easily transfer the Studio Fee. Occurring currency exchange costs will be at the account of the Studio.
More information on the Collectionstock commission percentage and Studio Fee can be found in the Studio Zone section under Studio Tools/Studio Fee. This section is only available for approved Studios.
