Key Challenges

Adapting pricing structures to evolving market demands

Embedding product innovations fast and seamlessly into the solution portfolio.

Managing complex billing cycles while ensuring a seamless user experience

Offering flexibility without creating operational bottlenecks

Best Practices

  • Implement dynamic pricing models, such as tiered subscriptions and add-ons, to maximize revenue.
  • Enable both recurring and ad-hoc payments to cater to different customer needs.
  • Automate invoicing and integrate self-service portals to reduce support overhead.
  • Use data analytics to identify the most effective pricing strategies based on customer behavior. For organizations focusing on b2c, A/B testing could be an option.
  • Enhance security through tenant protection at both the application and data layers.
  • Integrate with third-party financial platforms for efficient payment processing.

Why It Matters

As your SaaS business grows, so does the complexity of your subscription infrastructure. A microservices architecture ensures your platform remains agile, secure, and scalable.

Key Benefits

  • Independent scaling of core functionalities, ensuring high availability.
  • Faster iteration and deployment of new features without disruptions and zero downtime.
  • Flexibility to pick various tech stacks for different domains/features based on requirements. For example: Go lang or even C for performance sensitive stuff, Java/Kotlin or other high-level languages for others.
