The global SaaS market was valued at USD 237.48 billion in 2022 and is projected to reach USD 908.21 billion by 2030, growing at an estimated 18.7% CAGR between 2023 and 2030.

The United States continues to dominate the SaaS industry with 8.5 times more companies than any other country worldwide.

But what is driving such popularity of SaaS products? Unlike traditional software, the ease of access which eliminates the need for heavy infrastructure installation and maintenance costs have made SaaS an attractive digitalization tool for businesses of all sizes.

Another key driving factor is the rapid pace of digital transformation across industries. Organizations are increasingly seeking agile and scalable solutions to meet their evolving needs, and SaaS aligns with these requirements perfectly.

Furthermore, the ongoing trend of remote work and the need for collaboration and connectivity has further catalyzed the demand for a SaaS product development company.

The market clearly exists. The demand is constantly rising.

So you’re probably here because you want to know what it really takes to build a super successful SaaS product that will carve a decent share of this market.  

The SaaS development lifecycle is a good place to start and this guide will walk you through the key stages of SaaSDLC.

SaaS Development Lifecycle (SaaSDLC)

The SaaS Development Life Cycle is basically the step-by-step process of creating and delivering software applications over the internet as a service.

Let’s look at the core steps that make up SaaS development life cycle.

#1. Ideation

Ideation is the creative process of generating and refining ideas to identify a unique concept for a SaaS product, in this context. 

You may need to conduct some intense market research here. 

Market research allows you to gather valuable insights into the target market and identify potential opportunities. The goal is to ensure  your idea addresses a real pain point.

There is no shortage of the approaches you can use in this stage. But for the larger part, these will suffice:

  • Surveys and questionnaires: Use simple online survey tools like SurveyMonkey or Google Forms to gather feedback from your target audience and gain insights into their pain points.
  • Social media listening: Monitor conversations and discussions about your target market on social media platforms. Tracking mentions, hashtags, and discussions that relate  to your idea. Which tools can you use for this? Try tools like Buzzsumo and Sprout Social. 

The main actors in this stage:

  • Key stakeholders: May include founders, executives, and decision-makers who provide the product's strategic direction and what it’s intended to achieve.
  • Product managers: They provide critical help in gathering market insights, analyzing customer needs, and translating them into product requirements.
  • Development team: These are mostly software developers and engineers. They collaborate with stakeholders and product managers to contribute to ideas from a technical perspective. 

The key deliverable of this stage:

At the end of the ideation phase, the team should have a clear problem statement and a proposal for a  SaaS driven solution. The proposal should detail the clear need for a new solution.

#2. Planning  

At this stage, you want to ensure a clear understanding of project goals, scope, and the necessary resources to drive successful execution. 

The following are the core activities that are vital to this stage:

i. Requirements gathering and analysis  

During this activity, you actively involve stakeholders, including end-users, business analysts, and product managers. The primary goal is to collaboratively identify and document the desired features. 

Some examples of these features could be:

  • Performance requirements for both backend and frontend
  • Scalability expectations
  • Security considerations

ii. Evaluating and choosing a cloud service provider

The goal here is to evaluate different cloud service providers and select the most suitable for hosting your SaaS application. 

What to consider:

  • Reliability: Assess the track record, uptime guarantees, and disaster recovery plans of the cloud provider to ensure a dependable infrastructure.
  • Scalability: Evaluate the ability to scale resources up or down based on your application's changing demands. Can they deliver a seamless performance during peak usage periods.
  • Security: Scrutinize the provider's security measures, including data encryption, access controls, and compliance certifications. Are they capable of safeguarding your application and user data?
  • Pricing models: Analyze the pricing structures, such as pay-as-you-go or subscription-based models. Is the pricing cost-effective? Does it align with your budget   and usage patterns?
  • Integration capabilities: Assess the cloud platform’s compatibility with your existing systems.

You want to compare as many options as possible and make an informed decision that takes the future into account.

iii. Assembling the SaaS software development team

You want to make sure that you have a very good idea of the key SaaS developers that will drive the project. Yes, this is better done at the planning stage. 

Remember you may have already interacted with these professionals at the ideation stage. So picking those who will execute the project should not be very difficult.

Who are the key people to think about?

  • Software programmers
  • Product designers
  • Software architects
  • Quality assurance (QA) specialists 

iv. Choosing the appropriate SaaS software development methodology

Agile methodologies like Scrum or Kanban offer flexibility and faster time-to-market, making them ideal for evolving SaaS products. 

Evaluate the team's expertise and experience with different methodologies to ensure they can effectively execute the chosen approach.

It’s also important that you consider the level of collaboration and communication needed with stakeholders, as methodologies like Agile emphasize frequent interaction. 

Lastly, keep in mind the project's timeline and budget constraints, as some methodologies may be more cost-effective in delivering results. Please check this resource on how to budget for app development 

v. Choosing the technology stack

Here, you get to decide on the programming languages, frameworks, libraries, databases, and other tools that will be best suited for the project.

Start by evaluating the functional and non-functional requirements of your SaaS product to identify the technologies that best fulfill those needs.

What to consider for each technology option:

  • Maturity: Look at aspects like industry adoption to ensure a robust and well-established foundation for your SaaS application.
  • Community support: Is there an active and vibrant community around the technology. How easy is it to access valuable resources such as documentation, forums, and updates? 
  • Ecosystem: Evaluate the availability of compatible tools such as, libraries, frameworks, APIs, and plugins. These are essential for enhancing productivity during development.
  • Scalability:  Examine how well the technology accommodates scalability requirements, such as horizontal or vertical scaling.
  • Team proficiency: Assess the team's expertise and availability of developers proficient in the chosen technologies. 

The main actors in the SaaS planning phase include:

  • Product managers: Responsible for defining project goals and aligning the SaaS software development process with business objectives.
  • Business analysts: Key for requirements gathering, analysis, and defining the project's scope.
  • Project manager: Helps to match the project roles to the responsible persons, with timeframes and expected deliverables.
  • Development team: Provide technical input on technology decisions
  • Cloud architects: Assist in evaluating and choosing the cloud service provider.

During this stage, you can leverage project management tools like ClickUp or Asana to enhance collaboration and streamline task management. They provide effective ways to stay organized and work efficiently on your SaaS project.

At the end of this phase, the team should deliver the following:

  • Requirements documentation: A clear, detailed document outlining the functional and non-functional requirements of the SaaS application, with a section defining the roles of each team member.
  • Cloud service provider selection report: A comprehensive report highlighting the evaluation and selection criteria used to choose the cloud service provider.   

#3. Design & prototyping

This phase allows designers and developers to visually represent how the components of the proposed SaaS solution will interact. 

They also come up with a blueprint that allows stakeholders to validate and provide feedback on the proposed user interface (UI) and user experience (UX).

There are two fundamental activities that are essential for this phase to succeed:

i. Visualizing process flow, dependencies and delivery

This activity entails creating process flow diagrams, wireframes, and dependency maps to visualize how different components interact. 

Process flow diagrams are graphical representations that illustrate the sequence of steps or activities involved in a particular process. In the context of SaaS design, process flow diagrams are used to showcase how users will navigate through the system, what actions they can perform, and how data will flow between different components. These diagrams provide a high-level overview of the system's functionality and help stakeholders understand the overall workflow.

Wireframes are basic, skeletal representations of the user interface (UI). They focus on the layout of various UI elements such as buttons, forms, menus, and content sections. Wireframes are usually low-fidelity, meaning they don't include detailed visual design elements like colors and graphics. They serve as a blueprint for the UI design and help stakeholders visualize the proposed user interface.

Dependency maps illustrate the relationships and dependencies between different components of the SaaS solution. They help identify how changes or updates in one component may impact other components. Dependency maps can be used to represent both technical dependencies, such as API integrations or data flows, as well as functional dependencies, such as module dependencies or feature interdependencies. By visualizing these dependencies, designers and developers can ensure that all necessary components are accounted for.

ii. Building the SaaS prototype

When you develop a working model of the SaaS application, you get to validate it early on, gather feedback, and make iterative improvements. This way, you reduce the risk of expensive design changes during the later stages of development.

A prototype can also give you an easy way to raise money to fund your SaaS app development by pitching investors. This article explains how to use a prototype to pitch seed investors.Please check it out to learn more. 

Significant tools in this phase include:

  • Visualizing tools like Lucidchart, Microsoft Visio, or to create process flow and architectural diagrams.
  • Prototyping tools such as Figma, Adobe XD, or InVision to create interactive prototypes that simulate the user experience.

The main actors in this stage include:

  • UX/UI designers
  • Front-end developers
  • Product managers.

At the end of this phase, the team should deliver the following:

  • Process flow diagrams
  • Architectural diagrams
  • Dependency maps
  • Interactive SaaS blueprint with key screens, user flows, and basic functionality.

The development only begins after verifying that the prototype indeed depicts the proposed solution. 

#4. Developing SaaS product 

This is the core stage of the SaaS development lifecycle that brings together UX/UI designers, frontend developers, backend developers, QA engineers, and project managers.

Working as a team, these instrumental players translate design mockups to executable code that aligns with the user requirements.

Here are the significant activities in this stage:

i. UI/UX, frontend and backend development

UI/UX development creating visually appealing and user-friendly interfaces that align with the wireframes and mockups created in the design stage.

Frontend development focuses on building the user-facing components of the SaaS application, while backend development involves creating the server-side infrastructure that drives the product.

The application is brought to life by transforming the design and functionality into functional code. Different application modules are created independently and integrated to ensure communication within the modules.

But how can you tell that your system is performing as expected? Testing against the requirements!

ii. Testing and debugging (product environment)

It’s reckoning time:) Have we done a good job so far? 

Essentially, you want to establish the stability and reliability of the SaaS application that has just been developed. 

Each module is tested independently (unit testing), after which the integrated modules are tested against the user and functional requirements (integrated testing).

Testing is typically performed in a dev environment that closely mimics the production environment to ensure accurate results.

The last step in the testing exercise is acceptance testing, to confirm if the product is performing as expected. A key question is whether the app is ready for adoption.

iii. Refining and launch (live version)

Any necessary iterations or refinements are made based on the feedback gathered during testing. 

Once the application meets the desired quality and functionality standards, it is ready for launch. The live version of the SaaS application is deployed and made available to users.

The main actors in the development phase include:

  • UI/UX designers
  • Front and back-end developers
  • Quality assurance (QA) engineers
  • Business analysts
  • System users/testers

These are the core categories of essential tools for the development phase:

  • Programming languages (e.g. Python, Ruby), frontend frameworks (e.g., React and Angular), and backend frameworks (e.g. Django, Ruby on Rails).
  • Testing tools such as JUnit, Ghost Inspector, Rainforest QA, TestRail.
  • Continuous integration and deployment tools (e.g., Jenkins, GitLab CI/CD)
  • Hosting platforms (e.g., AWS, Azure, Google Cloud).

At the end of the development phase, the SaaS software development team should deliver the following:

  • Functional frontend and backend code, integrated databases, and APIs
  • Test reports of resolved bugs and issues
  • A deployed live version of the SaaS application.

#5. Maintenance

By now, your SaaS application is up and running. But SaaS development lifecycle does not stop at running.

You want to ensure consistent uptime through effective maintenance.

To do this, there are several key activities that you need to focus:

  • Bug fixes and issue resolution: When you identify a problem, you need to investigate it, diagnose the root cause, and fix it promptly.
  • Security updates: Cybersecurity is crucial for any SaaS product, so you must update your software's security measures on a regular basis. Examples of updates include applying security patches.
  • Feature enhancements: As you gather feedback from users and gain insights into their needs, you should prioritize and implement new features.
  • Platform and dependency updates: To ensure compatibility and leverage the latest technologies, you must keep your SaaS application up to date with the underlying platforms and dependencies it relies on. This includes updating frameworks, libraries, databases, and other components that your software utilizes.
  • Knowledge base maintenance: You should continually update the knowledge base to reflect any changes. This enables users and support teams to understand and utilize the application effectively.
  • Monitoring and analytics: Continuously monitor metrics such as uptime, response time, error rates, and user activity, to identify and respond to potential issues. Analytics also provide valuable insights into user behavior, allowing you to make data-driven decisions for future enhancements.
  • Continuous support: Provide ongoing support to users. 

The key actors in this phase include:

  • DevOps team
  • Infrastructure team
  • Support staff
  • System users

Important tools in this phase include:

  • Performance monitoring tools like Pingdom to analyze key performance indicators (KPIs) such as uptime.
  • Helpdesk ticketing systems, like Zendesk, to aid in managing user support requests and tracking their resolution and response time.

During this phase, the team should deliver the following:

  • Regular performance monitoring reports
  • Documented change requests
  • User support requests, bug fixes, and updates
  • Updated user manuals and tutorials

#6. Scaling

Great job when you reach here!

Your SaaS product is up and running. The early adopters like it. But you haven’t established the ‘big revenue driving’ customer base yet. 

This is the time to seize new opportunities by increasing the product's reach and market presence. 

So, you're probably wondering how to scale a SaaS product?  Well, let’s break it down by exploring the prominent methods that have proven effective.

i. Dominance play

Solidify the product's position in the existing market by continuously improving features and user experience to outperform competitors. 

This could also involve aggressive marketing campaigns, acquiring competitors, or pursuing aggressive pricing strategies. The goal is to establish a strong market position and gain a competitive advantage over other players that offer the same product.

ii. Establish presence in new markets

Partnership opportunities such as reselling can help combine strengths and expand your market reach. 

But how do you go about it? Start by identifying a complimentary SaaS partner whose offering can be of mutual benefit.

A good example of SaaS scaling that utilized this approach to great effect is the Slack and Zoom partnership. Slack, a popular team communication and collaboration SaaS platform, partnered with Zoom, a leading video conferencing solution.

The partnership allows users to launch Zoom meetings directly within Slack, simplifying communication and encouraging remote collaboration. 


As we wrap up, please note that the SaaS development lifecycle is not merely a series of steps to follow when building SaaS solutions. 

It also represents a fundamental approach that embraces the complexities of creating a successful SaaS product. 

At its core, SaaSDLC empowers teams to create a product that will deliver an enjoyable experience to users.

What could go wrong if you don't embrace SaaS development lifecycle when developing your SaaS app? 

One major risk that should concern you is the risk of creating a product that doesn't meet user expectations. Remember, SaaS development life cycle stands out for its ability to facilitate a comprehensive understanding of user needs and preferences, as it employs a user-centric approach. 

Without this in-depth understanding, your app may lack the desired features and usability, ultimately hampering user satisfaction. Consequently, the product may face low adoption rates and, ultimately, failure.
