PayPal is a payment processing service. A payment processor moves money from a buyer's account or card to a seller and handles the checks in between, such as fraud screening. PayPal Business is the part of PayPal for companies that sell online and in person.
A business adds PayPal Checkout to its website or online store, or sends invoices and payment links when it has no website. Customers pay with a PayPal or Venmo account, a credit or debit card, or a pay-later option, from more than 200 markets and in more than 130 currencies. The money arrives in the business's PayPal balance, from which it can be withdrawn. PayPal also offers risk and fraud tools, Seller Protection on eligible transactions, payouts to many recipients, business loans and a debit card. Developers connect it through APIs described in the developer documentation.
PayPal charges a fee on each payment that the business receives: a percentage of the amount plus a fixed fee that depends on the currency received, and an extra percentage for international payments. Separate fees apply to chargebacks, disputes and currency conversion.
