Payoneer charges fees for you to receive payments (usually no more than a few dollars) but these fees can vary depending on your location, the brief payment currency and other factors such as exchange rates.
For example, if you complete a brief that is paying out in USD, and your bank account is in USD, then fees will likely be minimal. However if you're receiving EUR and your bank account is in AUD, there may be more fees associated.
As the fees vary, it's important that you check the relevant fee details directly with Payoneer.
