What is SaaS development?

SaaS (Software as a Service) development is the process of building a cloud-based software product that users access via a browser or app and pay for on a subscription basis. Unlike traditional software, SaaS products require multi-tenancy (multiple customers sharing one codebase with data isolation), subscription billing infrastructure, onboarding flows, and cloud-native architecture built to scale from day one.

NexIT builds SaaS products for Australian founders and businesses — from pre-revenue MVPs validating a market hypothesis to production SaaS platforms handling thousands of subscribers. We handle the full stack: product architecture, backend API, frontend interface, subscription billing (Stripe), deployment infrastructure, and ongoing maintenance.
