How much will it cost to develop a custom SaaS solution in 2025?

The development of a web or mobile application in SaaS mode is one of the most structuring IT projects for a company in the process of digitalization. More than just a simple tool, it often involves creating a business software solution or management software designed to evolve with actual uses, terminals, teams, and market constraints. But how much does it cost? Unlike a standard software subscription or a turnkey CMS, a custom-developed project mobilizes a development team, software architects, frameworks, server environments, and a real design logic.

If you are just discovering the world of customized SaaS solutions, start with our main article on custom SaaS development. There you will find all the fundamentals: application architecture, programming languages, integration with business environments, user experience, ergonomics, etc.
This will help you estimate the cost of a custom software project more accurately, based on your level of digital maturity, your existing resources, and your long-term strategy.

1. Why there is no single price for a customized SaaS project

1.1. The cost depends entirely on the functional scope and business uses.

Creating a custom application is not just a matter of checking options in a configurator. Each specific development is based on your business processes, your customer relationship management, existing applications, your internal constraints, and your management tools (ERP, CRM, HRIS, extranet, etc.). Between a management application designed for 20 internal users and a collaborative management software package dedicated to several hundred external customers via an internet connection, the price differences are automatically significant.

Application developers will translate your business rules, organizational logic, and internal workflows into sustainable application components. It is these parameters—often invisible to end users—that explain budget variations.

2. The main cost items to anticipate

2.1. Scope, functional specifications, and architecture

Before writing a single line of code, a SaaS development project requires an application design phase supervised by a project manager or IT department. This phase will structure the technical foundation (framework, servers, database, API), lay the foundations for the information system, model the business application, structure workflows, and ensure compatibility with existing IT tools.

At Easyweb, this phase may include workshops with your employees, UX mockups, functional configuration, prototypes, and business validation. It generally represents 10 to 20% of the total software development cost.

2.2. Technical development: frontend, backend, connectors

This is where the development teams createthe web application,mobile application, or business software using the chosen languages (e.g., PHP, Symfony, Laravel, Java, etc.). This part covers the user interface, application logic, security components, automation, back office, rights management, authentication, and interoperability with other solutions (such as ERP or CRM).

Each development is tailored to your needs, with a modular approach to ensure scalability, backups, corrective maintenance, and access from various mobile devices (smartphones, tablets, PCs via web browser).

3. What price ranges can we expect to see in 2025?

3.1. Some indicative benchmarks according to functional scope

• Simplified MVP (single-function business app): between €20,000 and €35,000
• SME SaaS (dashboard, automation, multi-profiles): between €40,000 and €80,000
• Scalable business application/cloud ERP solution: starting at $110,000 depending on infrastructure, connectors, and volumes

These budgets are based on actual projects carried out or audited by our development agency. They take into account the agile method, the development cycle, integration with existing tools (management software, CMS, e-commerce platforms), ramp-up, architectural robustness, and the number of target users.

4. How to intelligently reduce the budget without sacrificing quality

4.1. Prioritize value through a targeted MVP

Good application development is based first and foremost on clear trade-offs: which features are critical to your business, and which can be added later? This MVP logic is at the heart of agile projects. We focus on the essentials (billing, resource management, activity management) to develop a robust, testable application that can be quickly deployed.

It is also a way to optimize development costs, acceptance testing phases, and module customization.

4.2. Focus on automation, responsive design, and scalability

A good SaaS solution is not limited to well-designed screens. It incorporates business automation, responsive design, collaborative dashboards, and ergonomics designed to reduce clicks and errors. By focusing onagility, the development team can also design a scalable application that can be adapted to new modules, future integrations, or gradual digital transformation.

5. Cost of custom SaaS vs. accumulation of standard software

A well-designed, tailor-made solution often replaces three or four poorly integrated standard software programs, avoids recurring license costs, reduces time wasted on unsuitable tools, and makes your sales management or customer relations more reliable. Where existing CMS or software programs force you to compromise, you regain control over the product, the budget, and the scope.

Over three years, a well-developed SaaS application specifically designed for your business can generate a much higher return on investment, thanks to its customization, stability, performance, and lower support or corrective maintenance costs.

Conclusion

The cost of custom SaaS software depends on the maturity of your project, the functional scope, the tools in place, and the level of customization desired. In 2025, the most successful companies will no longer be looking for the cheapest option, but the most suitable one. Custom development that is well-defined, well-prioritized, and well-supported is a sustainable strategic investment.
