What is SaaS Development?

SaaS (Software as a service) development is the process of building and deploying software apps over the internet. Since you host your software on the cloud, you don't have to install and maintain them on your computers.

SaaS development solutions offer many benefits in terms of scalability, easy deployment, and security. Thus, many businesses have started building SaaS products to streamline their processes. The global market for this industry is now worth $3 trillion and is expected to reach $10 trillion by 2030.

We offer three different models to handle your outsourcing SaaS development projects. Each of them comes with a unique set of advantages, serving different needs.

Dedicated Development Team

Like staff augmentation, this model involves building an external team for your business. However, the team then becomes part of your company and only works on the SaaS project. You may love this idea if you need experienced developers to deal with complex projects. It also comes into play for businesses that prioritize adaptability and a unified workflow.

Discuss your project

IT Staff Augmentation

This model integrates our team into your company to foster your workforce capabilities without hiring permanent employees. Hence, staff augmentation is the best option for businesses that want to adapt to changing requirements and avoid long-term employment. Our staff with specialized skills can help with your short-term projects.

Discuss your project

Project-Based Model

If you choose this outsourcing model, we will cover the complete SaaS development project, from its planning stage to deployment. Our team takes care of every aspect of the software and takes full ownership. Even so, we guarantee that the final product will align with your objectives. So, this model is best suited for projects with clear parameters.
