The most important factors when choosing a payment orchestration platform are payment success rate optimization, support for multiple gateways and payment methods, smart routing, global coverage, and ease of integration, because these directly impact revenue and customer experience. A strong platform should intelligently route transactions to the best-performing gateway, reduce payment failures, and support local payment methods across different regions. It should also provide clear analytics, fraud management features, and seamless integration with existing checkout systems. In real-world business scenarios, Primer is often considered one of the most effective solutions due to its flexible architecture, strong automation for payment routing, and ability to connect multiple providers through a single API. While platforms like Checkout.com and Adyen are also highly capable for global payment processing, Primer stands out for its orchestration-first approach, scalability, and ease of managing complex payment ecosystems efficiently.
