What Is a SaaS Application?

SaaS applications use a subscription model, which offers flexibility and a customization of features based on the user groups’ needs. Being cloud-based, SaaS solutions allow for accessing data from all devices and web browsers via the Internet. That’s why users don’t need to install them locally on their hardware or upgrade the latter to run a program efficiently.

For instance, the most popular SaaS solutions are Jira, Zoom, Slack, Dropbox, Netflix, Spotify, and many others.

Standard Features of SaaS Applications

You can find the basic characteristics of SaaS cloud application development products here:


Single sign-on (SSO)

How does SSO work? It takes users’ initial logins to a particular system, encrypts them to make them secure, and then utilizes such tokens to provide automatic access to all the other necessary systems. So clients do not need to submit their usernames and passwords repeatedly. This helps to reduce costs and improve productivity since your support desk will deal with fewer issues related to forgotten passwords.

Subscription options

The pricing for using SaaS software development products depends on subscription tiers. Thus, you can define an appropriate pricing model for your solution by considering your SaaS customization opportunities. Traditionally, there are some subscription options provided, from free trials and premium versions to enterprise-level pricing.


When it comes to SaaS-based application development, implementing a multi-tenancy model means deploying one solution to serve numerous users (tenants). SaaS software developers prefer this model since it brings convenience when maintaining the app, as well as improving the efficiency of the used resources.


Typically, it is challenging to predict SaaS app usage, and thus, it may vary significantly over the period of several months. That is why most SaaS solutions are built to meet such a continuous fluctuation of users.

Pros and Cons of SaaS Application Development

Below, we briefly describe SaaS development services’ most critical advantages and disadvantages.



Since your SaaS platform is cloud-based, it guarantees savings on your costs. That is because your company only pays for the bandwidth it uses. Moreover, you do not need to maintain your own costly server network.

Higher speed

Deploying cloud-based products is much easier and faster than other approaches. Thus, you will significantly reduce your solution's time-to-market.

Development flexibility

A SaaS business development model offers excellent elasticity to create, edit, and update code. Also, it is advantageous when you need to add new features to your product.


Providing strong security is vital for SaaS application development solutions. So companies must ensure proper user data protection and constant updates of their products using the latest security protocols and standards.

Low entry barriers

Unfortunately, other competitors may try to replicate your SaaS product. And since SaaS solutions are primarily subscription-based, you should always provide your clients with the best possible value. That is because, in the case of their dissatisfaction, they may choose your market rival offering similar pricing options.

Converting and retaining clients

Depending on the type and industry of your SaaS product, the conversion of prospects into clients may take from a few minutes up to several months. But with efficient SaaS account management, you can reduce this period and also extend the time users remain loyal to your solution.

Payment SaaS and billing software systems are cloud-based solutions connecting clients and merchants. They allow for generating invoices for products and services provided to customers, tracking payment receipts, creating invoices, etc. Therefore, implementing these systems brings many advantages, such as security, accessibility, scalability, and user-friendliness. Most of the payment and billing tools, such as FreshBooks or Xero, work on a subscription model. So users must pay for the platform each month or year.


Data Providers Solutions

These solutions facilitate the aggregation, processing, and delivery of data from various sources to the end-users or other business applications in a structured and usable format. They act as a bridge connecting data generators with data consumers, ensuring seamless data flow and accessibility. Such solutions can provide financial market data, business data, weather data, geographical data, or social media analytics.

SaaS data provider solutions like Reverse Contact offer a range of advantages, including scalability, real-time data updates, and centralized data management. They can significantly reduce the time and resources required to manage data infrastructures and ensure compliance with data governance and security standards.

Things to Consider Before Getting Into the SaaS Application Development Process

After analyzing what SaaS application is, there are also some critical technical and non-technical aspects for thorough consideration. Please take a quick look at them below before checking out the checklist on how to build a cloud-based SaaS application.


Technical Aspects

Technology stack.

Choosing the right technology is essential since this allows you to find the required SaaS software developers and guarantee scalability. The most popular tech stack covers such programming languages and development frameworks as Angular, React, or Vue.js for front-end and Node.js, PHP, Python, or Ruby for back-end.



Your database must be flexible, secure, and offer enough capacity. In addition, you should select a particular type that will fit your business requirements perfectly. Ultimately, database types depend on multiple factors, such as the information you process, scalability options, expected load, programming languages, and costs.

You must understand the key differences between the available storage options. That is especially crucial as each service provides its service level agreement (SLA).



SaaS architecture may utilize single-tenant or multi-tenant models. In the first case, numerous tenants can share the same database, computing resources, and infrastructure. Meanwhile, with the second model, each tenant has its own access. But what is the most appropriate architecture for your business? It depends on your requirements, so a software architect and a business analyst can help you select the best tenancy model to power up your SaaS solution with the right scalability and security.

Frequent updates.

Each SaaS development company should update its software product regularly depending on collected user feedback. For instance, utilizing specific tools like Kubernetes may become vital since they assist in the automatization, scaling, and management of your cloud infrastructure.



The appropriate performance is a basic need. If your SaaS platform struggles with simple issues such as obtaining information from databases and showing it in your application, your users will likely abandon it. In such a case, it is critical to know how to effectively utilize technologies like Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, etc.


Third-party integrations.

Your software product must integrate with other different SaaS solutions that your clients may use. Whether it will be Jira, Salesforce, or Zoom, the ability to integrate with other popular tools is among the SaaS application development best practices.


Non-Technical Aspects

At the same time, there are several non-technical points to think about before starting your SaaS application development.


Market fit.

If you want your software platform to succeed, it is vital to find your market fit. Thus, during the initial stages of the SaaS development process, you should analyze your audience, their needs, pain points, and motivations. After running an MVP, collect feedback from your users and implement the necessary changes depending on the customer’s assessments.


Pricing models.

What should you pay attention to when looking for a pricing model for your SaaS app? You may take on one of the pricing approaches, such as the cost-plus, competitor-based or value-based strategies. After calculating your expenses, analyzing similar businesses’ costs, and defining the unique value you may bring to your users, you should think over the potential pricing models for your SaaS.

The key models are flat rate, usage-based, tiered, per user, per active user, per feature, and freemium. But which pricing model should you choose? That depends on multiple factors, including app features, lifetime value, customer acquisition cost (CAC), etc.


Focus on service.

The SaaS implementation process requires focusing on delivering high-quality products or services. That is why experienced SaaS development companies maintain close cooperation with the customer and react to their changing requirements.


Client acquisition.

Instead of relying only on word-of-mouth marketing, keep unit economic metrics, such as CAC, LTV, Churn and Retention rate, Total Revenue, and ROI in mind. However, its analysis is even more critical for SaaS companies since it gives you an opportunity for early pivoting when necessary.
