Things to Consider Before Developing a SaaS Application

However, to lay a strong foundation for your SaaS project, it’s important to evaluate several key aspects—ranging from performing thorough market research to outlining a strategic roadmap and assembling the right development team. Let’s explore these considerations further:

1. Conduct Thorough Market Research

With more than 30,000 SaaS companies competing for a share of the profitable SaaS market, simply launching a SaaS product without prior planning is unlikely to yield success. This oversight can be extremely expensive, particularly if the application you develop fails to address a genuine market demand. To maximize your chances of success, it is essential to undertake comprehensive market research. A good starting point is to assess the competition, as this will help you pinpoint gaps in the market that your product could effectively fill.

Answer these questions to conduct a competitive analysis:

What is their unique selling proposition (USP)?
What are their strengths and weaknesses?
How do they market their products?
What do their customers say about them?
How do they price their products?

As you analyse your competitors, it’s crucial to identify how you can set your product apart. Focus on aspects such as pricing, features, and customer support. One effective strategy is to take advantage of free trials that most SaaS products offer, allowing you to experience their services firsthand.

Pay close attention to the areas where these competitors may be lacking, and think about ways to provide added value. For instance, if you find that their offerings are too complex, consider developing an application that emphasizes simplicity and user-friendliness—a tactic that Zoom successfully used to attract users from Skype.

2. Define Your Target Audience and Create User Personas

Once you have completed your market research, the subsequent step involves identifying your target audience by developing user personas. These personas are fictional representations of your ideal customers, designed to encapsulate their characteristics, preferences, and behaviors. This process helps you tailor your product and marketing strategies to better meet the needs and expectations of your potential users.

Distributing surveys and performing individual interviews are excellent methods for collecting valuable insights about your prospective users. Utilize the data you’ve gathered to develop comprehensive user personas that reflect their needs and behaviors.

A clearly outlined user persona allows you to design a more engaging product. For instance, if you discover that a significant concern for your users involves tedious, repetitive tasks, you might consider creating an application that focuses on automation to address this issue effectively.

3. Establish a Product Vision and Decide on a Development Approach

Once you have a firm grasp of your target audience, leverage the insights you’ve obtained to formulate a distinct vision for your product. Define the ways in which your application will address the challenges and needs identified among your audience, ensuring that your solutions align with their preferences and pain points. This clarity will guide your development efforts and enhance your product’s relevance in the marketplace.

Horizontal Development: This strategy involves designing a software product that caters to a wide audience. For instance, accounting software that accommodates various use cases can attract a larger potential market; however, it may face difficulties in differentiating itself from competitors.
Vertical Development: This method focuses on creating a product tailored to a specific niche or industry. An example is accounting software specifically for nonprofits, which allows for a more targeted solution. While this approach can lead to more precise offerings, scaling the product may prove to be more challenging.

4. Develop a Minimum Viable Product (MVP) Roadmap

Having established your application’s objectives, the subsequent focus should be on formulating a roadmap for your Minimum Viable Product (MVP). This roadmap outlines the essential steps you will take to test and launch your SaaS product while utilising minimal resources. The goal is to validate your concept in the market efficiently, enabling you to gather user feedback and make necessary adjustments before a full-scale release.

The MVP serves as a crucial basis for iterative development, offering key insights for future improvements. By focusing on only the essential features, you can avoid unnecessary expenditures on superfluous additions. Launching an MVP early enables you to test your concept and adjust subsequent updates in alignment with customer feedback.

Take Buffer as an example; this well-known social media marketing tool began as a simple solution for scheduling tweets. Despite its limited functionality at first, the significant user interest validated the concept and encouraged the founder to invest further resources. To create an MVP, identify the fundamental features and functionalities required to realise your concept. Prioritize these elements based on user demand and technical capability, as they are vital for addressing user pain points and providing a rewarding experience with your application.

5. Decide On a Pricing Strategy For Your Product

Selecting an appropriate pricing strategy is crucial for the success of any SaaS product; setting the price too low can jeopardize your cash flow, while pricing it too high might deter potential customers.

A good starting point is to conduct a competitive analysis. Examine your competitors’ pricing structures: what do they charge, and what models do they use? Do they have flat fees, tiered pricing, or usage-based options? This research will be instrumental in shaping your own pricing approach. Additionally, consider the competitive landscape you’re entering.

If the market is crowded, offering a freemium plan can help draw in new users. For instance, Notion adopted this strategy as a productivity tool competing with brands like Asana, Evernote, and monday.com, enabling them to attract a broader audience.

6. Assemble a Talented Development Team

It’s essential to have the right personnel in place to bring your application to life. Begin by determining whether you will handle development internally or enlist the help of external SaaS developers.

Conduct a cost-benefit analysis to weigh both options and assess the necessary skills and expertise for effective development, which includes front-end and back-end programming, cloud infrastructure management, and security measures. If your team possesses the required skills and can dedicate the necessary resources to the project, building the application in-house might be viable.

Conversely, if these capabilities are absent, outsourcing the development to skilled professionals could prove to be a more economical choice.
