Your business model requires deep, complex customisations to core commerce logic that cannot be achieved with a SaaS platform, and you have a dedicated agency partner.
You are building an API-first, composable (MACH) architecture and see your ecommerce platform as an engine, not the entire solution, with mature internal engineering.
Key risk: A business underestimates the long-term cost of security patching, maintenance, and version upgrades, believing the platform will largely run itself after launch.
