This document discusses the evolution of online payment platforms and the benefits of modern all-in-one payment platforms. It outlines three generations of payment platforms: early gateways for basic card processing (Gen 1), APIs that enabled regional card processing (Gen 2), and current all-in-one platforms that optimize mobile and cross-border sales (Gen 3). Gen 3 platforms provide built-in functionality for checkout, virtual terminals, subscriptions, invoicing and more. Using these platforms is shown to increase sales and transactions while reducing costs compared to older methods. Key trends in the payment industry like growing mobile and global sales are driving businesses to upgrade to next generation all-in-one payment platforms.
