Frequently Asked Questions
1. What is the difference between custom software development and SaaS?
Custom software is built specifically for your business needs, offering complete control and flexibility. SaaS (Software as a Service) is a subscription-based product that serves many users with similar needs. Unlike SaaS, custom software can be tailored to your workflows and scaled uniquely.
2. Is custom software development the same as SaaS?
No. Custom software development creates a unique solution tailored to your business, while SaaS is a pre-built product that you rent and use. SaaS is ready-to-use, whereas custom software requires time and planning to build from scratch.
3. Can SaaS software be customized?
SaaS platforms allow limited customization—like branding or feature toggles—but you can't modify the core functionality. For full control and complex integrations, custom software is more flexible.
4. When should I choose custom software over SaaS?
Choose custom software when your business has unique workflows, data security requirements, or complex integrations that SaaS can’t support. It's best when scalability, long-term cost control, and competitive differentiation matter.
5. Which is more cost-effective: custom software or SaaS?
SaaS is more cost-effective short-term due to lower upfront costs. However, custom software can be more economical in the long run if you need advanced functionality, user scaling, or licensing control, especially for large teams.
6. Does custom software take longer to build?
Yes. Custom software usually takes weeks or months to develop because it’s tailored from scratch. However, using agile methods and MVPs can speed up delivery and reduce time-to-market.
