n8n's pricing model is designed to be both affordable and scalable, which is particularly beneficial when integrating with OPN (formerly Omise). Unlike other platforms that charge per operation or task, n8n charges only for full workflow executions. This means you can create complex workflows with OPN (formerly Omise), involving thousands of tasks or steps, without worrying about escalating costs. For example, if your OPN (formerly Omise) workflows perform around 100k tasks, you could be paying $500+/month on other platforms, but with n8n's pro plan, you start at around $50. This approach allows you to scale your OPN (formerly Omise) integrations efficiently while maintaining predictable costs.
