iPaaS platforms like Workato, Boomi, and Tray.ai are general-purpose integration tools. They auto-map data fields between any two systems but have no built-in understanding of payroll. A context layer like datascalehr is purpose-built for global payroll connectivity. KMod predicts mappings, validations, and transformations based on 1.5M+ validated decisions across 150+ countries and 7,000+ schemas. iPaaS deployment runs 1-3 months per country with no compounding benefit. A context layer deploys in hours per country.
