Hello, the most important advantage for e-commerce is automation. After connecting the system to the site and setting up the store, the seller only discusses the delivery details and sends the goods. The system itself generates an invoice for payment for the order, a request for secure payment, and then it itself transfers the money to the seller's settlement account. Payment systems for the site are needed by any online store that sells physical and digital goods or provides services. By the way, the company at PayAdmit: Online Payment Processing | Payment system for the site, the service for accepting payment (https://payadmit.com/) provides one of the most efficient payment solutions for businesses.
