We always charge 0.10 EUR + VAT per correct operation, no matter which payment method you use. Each payment method you use through us will charge you directly its commission, since you will have the contract with them to negotiate directly with each provider.
We have additional services such as IVR, pay by link via SMS or Email. In the case of SMS or Email, you can also use a service with your own account, such as Twilio, Vonage/Nexmo or your SMTP server.
