The cost of buying a PayPal account varies depending on the type of business you run. Some small businesses might only use the account for small-scale transactions, while larger ones might need to set up a more sophisticated payment system. PayPal has many features, including a mobile application. In addition, it doesn’t charge monthly or annual fees. However, you should expect to pay 2.7% + $0.15 per transaction for keyed transactions, plus 1.5% for currency conversion and cross-border fees.
