What is SaaS application development?

Custom SaaS development in 2026: modern stack (Next.js, Supabase, Stripe), steps from MVP to scaling, real price ranges, and production considerations.
SaaS application development is a rapidly growing market. SaaS applications support businesses daily in their various needs and address a major challenge: mobility. Before diving into developing these applications, it’s important to understand what SaaS is and its benefits. Through this article, ’Agence Scroll explains everything about SaaS application development, its advantages, and how to get started!
What is SaaS application development?
SaaS stands for “Software as a Service,” which translates to “logiciel en tant que service” in French. A SaaS application is an online-hosted application that doesn’t require installation on a computer or other device. It’s accessible from anywhere, simply via an internet connection and a browser.
For several years now, the SaaS application model has far surpassed the traditional model of software installed on a computer.
What are the advantages of SaaS application development?
SaaS application development owes its success to the many advantages it offers, both for businesses and their customers.
The advantages of SaaS applications for businesses
Users can start using the application quickly.Since no download or installation is required to use the application, users can start using it very quickly. This makes onboarding much easier and faster than if they had to download and install software. This significantly increases the number of users.
Billing is simple and automatic. SaaS applications typically operate on a subscription basis. Billing is generated automatically based on each subscription, and payments are processed online, just like any other internet purchase.
Reduced development costs. A SaaS application consists of a single core block to which features are added as optional modules based on the client’s needs. Unlike installed software, there’s no need to create multiple distinct versions. This helps save on application development costs.
The advantages of SaaS applications for customers
An up-to-date application. The customer no longer needs to worry about updating their application. Since SaaS applications are hosted online, the application is always kept up to date by the developers. All users benefit from the same version of the application at the same time, without having to download or install updates.
Resource usage. SaaS applications do not use the customer’s hardware resources. Since the application is fully hosted online, the hosting provider supplies the power needed to run it. This makes the required hardware resources much more accessible for the customer.
A price tailored to specific needs. Thanks to the subscription-based payment model with selectable features, the client can tailor the offer precisely to their needs. More specifically, they can adjust their plan based on the number of users required and the features needed. This allows the client to save money since there’s no upfront investment to amortize.
The flexibility of the offer.SaaS applications offer clients a certain degree of flexibility. Depending on the plan, clients can add or remove users or features from their subscription at any time.
Mobility. SaaS application development is a major asset for mobility. Applications are accessible from anywhere, at any time. Whether the client is in the office, traveling, working remotely, or at a trade show, the app remains accessible from any device.
