Choosing between Custom SaaS and Off-the-Shelf software is a critical task. While an off-the-shelf software gives you the appeal of immediate implementation, a custom SaaS is tailored to the requirements and may have a longer development cycle.
Problem-SolvingCustom SaaS addresses your unique business problems, while an off-the-shelf software designed for massive usage may or may not include required problem-solving features.
ScalabilityA custom solution can quickly adapt to business growth, whereas off-the-shelf software often comes with usage limitations and performance issues with an increase in load.
IntegrationCustom SaaS can integrate seamlessly wth existing API and tools; off-the-shelf software may require third-party tools to complete integration.
SecurityOff-the-shelf software consists of shared code and thus has limited security; custom SaaS can add security at each level of the software, tailored to your requirements.
Software OwnershipWhile custom apps provide complete ownership and control over code and user experience, off-the-shelf solutions are vendor-dependent.
CostCompared to off-the-shelf software, custom SaaS comes with higher upfront costs but is cost-effective in the long term.
Easy Access:The mobile application allows the users to access the SaaS application anytime and from anywhere. Multi-device accessibility ensures that users get app access across all mobile devices.
Improved Usability:The mobile-optimised interface improves usability and navigation, and the app may support built-in device feature integration for camera, GPS, etc, making it easier for users to complete the work on the go.
Competitive Edge:A mobile application gives a competitive edge, as your brand looks different from competitors who depend only on web applications. You can attract a user base seeking mobile-based apps. Besides, the mobile app provides Instant access to critical features.
