SaaS Website Development FAQ & Customer Testimonials

Real results from our SAAS Customers
What is SaaS development and is it right for my business?

SaaS (Software as a Service) is a subscription-based software model delivered online. It’s ideal if you want to offer software tools and platforms or services to customers who pay monthly or annually. Examples include project management tools and CRM systems or analytics platforms.

We build comprehensive SaaS platforms with user authentication and subscription billing (Stripe and PayPal) and role-based access and dashboards and APIs and multi-tenancy and analytics and email notifications and third-party integrations and white-labeling and admin panels for complete business management.

We integrate robust payment systems with automated recurring billing and multiple subscription tiers and trial periods and proration and invoice generation and payment retry logic and subscription upgrades and downgrades and detailed revenue analytics to manage your SaaS business efficiently.

Our Thai & English-speaking team provides end-to-end support for SaaS projects including planning, development & deployment and ongoing maintenance. We can develop in phases to help you validate your concept with real users early and iterate based on feedback.

  • Sierra Group truly offers the best price and service. We worked with their team to develop our restaurant website, and the team at Sierra was incredibly helpful throughout the entire process. They helped us create a beautiful and functional website that exceeded our expectations. What impressed us most was their willingness to make numerous small changes to ensure we were completely satisfied with the final result. I really appreciate their excellent work and hospitality. I will definitely return to Sierra Group for future website services. Highly recommended!

  • I've had the pleasure to work with Sierra IT on a number of projects, from building basic websites to full on web shops. As a one stop shop, they do all aspects from website design, coding, and SEO. Even helped us set up payment processing. For every project they've worked efficiently and fast paced, and gone above and beyond for every aspect of website design. If anything they are too fast and the customers are the ones that feel slow since we have to take time to finally decide what it is we want! If anyone is on the fence, get off it and work with these guys. I'd give 10 stars if I could.
