For many customers, the whole WooCommerce setup may be excessive depending on the type of product, and how much they are selling. We all know PayPal from eBay and other online stores and this may be a better way for a business to accept payment. The PayPal payment screen allows for all major credit/debit cards as well as a PayPal payment so you would not be limiting customers.
There is no login/account aspect to using PayPal payments so it does allow for a straight forward click, pay, wait for delivery type of approach. Some customers like this as it is deemed less fussy and less chance of being swamped by marketing emails.
All any online trader needs is a business PayPal account, this provides a code Dynamiser would use with a set of PayPal buttons created via a PayPal WordPress Plugin. The buttons can be seen in the example below and both buttons redirect the customer to PayPal where they login and pay. PayPal then send the trader an email with order and delivery details and the payment lands in the traders PayPal account.
