British Swim Schools operates a national network of hundreds of franchises, each managing up to 15 locations within their territory — a sprawling, complex system where keeping data accurate and consistent across every level is no small feat. The core challenge: building a architecture that could sync franchise and location data to a master database, while maintaining isolated child databases for franchise-specific information, all without letting one franchise’s data bleed into another’s. Layered on top of that was a full enrollment system for their swim programs, tying locations, schedules, and customer signups into one cohesive flow. The result is a platform that brings order to franchise chaos — giving British Swim Schools the infrastructure to grow without losing control.
