In this chapter, we review the special payment methods (services) supported by Sellvio.
Please note that not all payment methods are available in every country, and each payment method has its own list of supported currencies.
IMPORTANT: All payment methods provided with Sellvio require the store owner’s company to enter into a contract with the respective payment provider they wish to offer to their customers during the checkout process.
Once the contract is signed by the store owner and the payment provider, the provider will supply the necessary credentials and configuration parameters to the store owner. These can then be entered into the fields of the configuration form for the respective provider in Sellvio.
