No, there are none. One of Penta's core values is transparency - we make it as easy as possible to understand our pricing model and always keep our list of services & prices up to date. 

Today each Penta account includes 10 free outgoing transfers a month, every additional transfer costs 10 cents. As your business and your needs grow, you can pay for additional services and features if you need them. This pricing model lets you only pay for what you use.
