Fivetran is an integration platform that uses a usage-based pricing model, where customers are charged only once per month for monthly active rows (MAR), which are distinct primary keys added, updated or deleted from source systems to destination systems by connectors. The cost is calculated based on the total monthly usage and spend rate, which depends on two factors: volume and pricing plan. Fivetran offers various free features and trials, including initial sync, new connectors, resyncs, and private preview connectors. To get the most out of Fivetran, it's essential to understand how source systems affect MAR and engage with stakeholders to discuss value and total cost of ownership. The platform provides a usage estimator and pricing page for customers to explore different scenarios and pricing plans.
