Project Steps

Our development process is completely transparent, and the customer has access to the application at any stage. See the SaaS development lifecycle we adhere to.

Analyze Requirements

We discuss the requirements for the project and its goals with the customer and prepare a specification if necessary.



Based on an analysis of the requirements, we draw up a roadmap and project implementation plan and set goals for the upcoming sprints.


Architecture Design

The next step is building the core of the SaaS development platform and writing the source code.



Once the prototype is completed, we send it for testing so that our quality assurance specialists can verify the functionality and compliance with the requirements. If any bugs are found, they are instantly fixed. As per client wishes, they can also join an app check at this stage.



We integrate the product with various third-party resources to expand its capabilities.



After all the functionality has been created and approved, we prepare the application for a live release.



As soon as a product enters the market, our team continues to support and administer it, adding or modifying functionality and updating technologies.

Frequently Asked Questions

Below we have prepared more useful information for you.
What is SaaS Development?

SaaS (Software as a Service) development is when a provider creates the application and places it online. SaaS applications are cloud technologies, so users can access the product from anywhere in the world and do not need to download it to their smartphone. The idea is that most of these applications are free, but have a variety of monetization models. For example, Google Drive is a SaaS app. Any user can get 15 Gb of storage for free, but the placement of files over this volume occurs at an extra price.

Do I need to build a SaaS app from scratch?

If you have a business idea, we will be happy to help you implement it. If you already have a SaaS application and you want to modernize or update it, we will also provide you with all the necessary range of services to achieve your business goals. If you have an application and want to transform it into a SaaS product, our team will make all the necessary development steps.

Can you support my product after release?

Sure. By clients' requests, we support and update products even after they have entered the market. Our team is committed to a long-term partnership and we will be happy to maintain your application further.

Can you estimate my project?

KeyUA technical experts will be happy to review your idea and draw up a project implementation plan. If you need an estimation of the time for development and price of your product, we will provide you with a free consultation and a detailed report. Feel free to contact us at any time.
