Depends on the method the customer choose to pay you - if you're not sending invoices and allowing the customer to simply send you money via your email address, if they choose the option for "Friends and Family" and use money from either their bank account or PayPal Account Balance - there's "no" fees. If the customer uses a credit card or selects "Goods and Services", there are fees. If you send an invoice there are fees. If you're using PayPal Here there are fees. And if you have a Business Account and send a PayPal.ME link, there are fees.
