SaaS Application Development: How to Build Your Own SaaS App From Scratch?

Learn About SaaS Development

Software is no longer something you install and update manually. These days, we interact with most applications through the cloud – a model known as “Software as a Service” or SaaS.

Rather than purchasing licenses, with SaaS you simply subscribe to use apps over the internet. The software lives on the provider’s servers and gets delivered through your web browser or mobile app.

Building SaaS applications is very different from traditional software development. Your app has to be structured to serve multiple tenants or customer accounts from the same codebase. 

Creating a successful SaaS solution involves many crucial steps – validating your concept, designing an exceptional user experience, architecting cloud infrastructure, implementing, and providing top-notch customer support.

In this guide, we’ll walk through the full lifecycle of SaaS developing a robust, secure, and scalable SaaS application ready for the prime time. Whether exploring SaaS as a new career direction or looking to modernize your approach, this is your start-to-finish roadmap.

Let’s dive into mastering the unique methodologies and processes involved develop a SaaS application!

Let’s get started with the basic question.

What is SaaS Application?

At its core, a SaaS or “Software as a Service” application is software that gets delivered over the internet – no installation is required on your computer or mobile device.

Rather than buying a copy of software that’s yours forever, with SaaS you’re basically just renting or subscribing to use the app. The actual program and all your data live on the company’s servers in the cloud.

From a company perspective, building SaaS apps is also a smart model versus traditional boxed software. They can instantly reach customers worldwide without manufacturing discs or downloads. But it also introduces some unique tech challenges around scalability, security between different user accounts, and seamlessly pushing updates.

Still, the convenience factor of SaaS has made it super popular in recent years. A ton of tools you likely already use daily – stuff like Google Workspace, Dropbox, Salesforce, Slack, Zoom, and more – are all SaaS products making our work and life easier through the magic of the cloud.

A Step-by-step guide to SaaS app development

Developing SaaS applications that can reliably and securely serve a large user base through the cloud introduces some unique engineering challenges around scalability, multi-tenancy, automated testing and deployment pipelines.

But when done right, SaaS unlocks amazing opportunities to build software that provides incredible value, reaches global audiences, and adapts rapidly to changing customer needs – all through the power of the cloud.

Step 1: Researching the Market for Your SaaS Application

Diving headfirst into creating a SaaS app without proper planning is a guaranteed path to squandering both time and resources.

The smart approach? Do your homework upfront through solid market research. 

Get out there and actually talk to your potential users – run surveys, interviews, join online communities in your problem space. 

The goal is to deeply understand their struggles, frustrations, and desired outcomes. What job are they hiring your product to do? You need those raw insights directly from the source.

Thoroughly analyze what competitors and alternatives are already out there is best way to start your developing SaaS application journey.

Step 2: Defining the Minimum Viable Product (MVP) for Your SaaS App

With all your user and market intelligence gathered you can start defining your minimum viable product (MVP) – the lean, core solution to put out into the world first.

Avoid attempting to do everything at once! Reduce the scope to just the most essential set of features that deliver value and solve real problems for your early adopters.

Mapping out the user flows, epics and requirements for this MVP is crucial. But also critically think through what the future product roadmap beyond the MVP will look like. That upfront planning and visioning lays the foundation for an evolvable SaaS product down the line.

Step 3: Gathering Essential Resources for SaaS Application Development

Every SaaS app needs the right players and tech stack in place to turn your vision into reality. On the human resources side, you’ll need a cross-functional team with skills spanning product management, UI/UX design, full-stack development, QA engineering, DevOps, and potentially sales/marketing.

Don’t try to cut corners by having general web developers simply try to “figure out” how to build a SaaS application. 

You need people with direct experience designing and developing cloud software with scalability, multi-tenancy, and continuous delivery in mind from Day 1.

From a tooling and infrastructure perspective, you’ll need cloud hosting, CI/CD pipelines, monitoring, containerization platforms, artifact repositories, communication tools for your distributed team, and more.

Step 4: Prioritizing UI/UX Design in SaaS App Development

Your UI/UX design team has to be involved from the very beginning, not tacked on at the end. After all, the user’s entire experience of your application is through those software interfaces.

Invest heavily into upfront user research, persona development, wireframing, prototyping, and stakeholder feedback cycles.

Run usability tests during the design phase before writing production code. The goals are intuitive navigation, clear information architecture, and ideally even delightful micro-interactions.

Don’t let your engineers default to dull, dated UI frameworks and conventions. Push for modern, visually-appealing user interfaces with responsive, mobile-first approaches in mind. Well-designed cloud apps provide simple, cohesive experiences across devices.  

Step 5: Estimating the Costs of Building  SaaS Application

As the requirements and designs for your MVP come into focus, you’ll need to carefully estimate the implementation costs – both upfront and for ongoing development/operations.

On the initial build side, factor in your team’s salaries or contractor rates, any paid tool subscriptions, cloud infrastructure fees, and buffer for unexpected needs.

For long-term, recurring costs, you’ll need to account for variables like hosting consumption scaled for your projected user growth, contracted DevOps/support services, marketing spend to acquire customers, and most critically – your sales engine’s ability to drive revenue and cash flow from subscriptions.

Step 6: Selecting the Tech Stack for Your SaaS App

Your SaaS tech stack selection deserves particularly meticulous planning and consideration. The core programming languages, frameworks, databases, CI/CD tools, cloud services, and more that you standardize on form the critical infrastructure.

You want a proven, scalable stack suitable for distributed cloud computing rather than traditional monolithic app stacks. Look at what leading, mainstream SaaS players use.

Favor technologies with robust performance, third-party integration capabilities, and healthy open-source communities.

Developing on proprietary, niche, or new/unproven platforms may seem appealing. But will those have the resources, skillsets, and ecosystem available to evolve and scale your app over the years? Probably not the safest bet for a SaaS product’s longevity.

Step 7: Managing Deployment and Support for Your SaaS Application

Just getting your initial SaaS app shipped is only half the battle. Having processes for continuous delivery of enhancements while providing top-notch, proactive customer support is mission-critical.

On the deployment side, you’ll need robust automated testing environments, CI/CD pipelines, and mechanisms to push updates without impacting users. You’ll also need monitoring, logging, analytics, and incident response protocols to maintain uptime and performance.

Equally important is supporting your customers through channels like live chat, email, phone, knowledge bases, and community forums. Plan for hiring and staffing roles like customer success managers, technical support analysts, docs writers, and more. Ongoing education through videos, webinars, and hands-on training resources is valuable too.


As we come to the end of our discussion on Software as a Service (SaaS), let’s simplify it. SaaS means using software via the internet, or the “cloud,” rather than downloading it onto our computers.

This approach makes software more accessible and keeps it up-to-date effortlessly.
