Are you considering custom software development?
Trying to understand what custom software development costs before committing to a discovery call? This article breaks down how custom software is priced, what drives costs up or down, and what you can realistically expect at different project sizes.
How much does custom software development cost?
Custom software development costs depend on team size, project duration, and complexity. Here are typical ranges based on our experience since 2009:
Small projects, such as MVPs, small DevOps engagements, or cloud migrations, start at around €25,000/$30,000 for one full-time developer over one to two months.
Medium projects, covering multi-module web applications, API integrations, or database platforms, run €50,000/$60,000 to €200,000/$225,000 and typically take three to six months with one or two developers.
Large enterprise projects involving multiple systems, complex integrations, or regulatory requirements can exceed €250,000/$300,000 and run six months to two or more years with teams of three to five developers.
What drives the cost up or down?
The biggest cost drivers are team size and duration. Beyond that, the following factors increase complexity and therefore cost:
Third-party integrations. Every API connection to an external system, whether a payment processor, an ERP, or a government data source, adds scope and testing surface.
Legacy system involvement. Migrating or integrating with an existing system that lacks documentation or has inconsistent data requires significantly more time than greenfield work.
Regulatory requirements. Healthcare, finance, defense, and government projects carry compliance overhead that affects architecture decisions, testing, and documentation.
Performance and scale requirements. A system that needs to process thousands of transactions per minute is architecturally different from one handling dozens.
User experience complexity. A consumer-facing application with a polished UI and mobile optimization takes longer than an internal tool used by trained staff.
What is included in the monthly rate?
At Volare Software, our monthly rate covers development, code review, automated testing, deployment, and project communication. We do not charge separately for sprint planning, architecture decisions, or progress reporting. You pay for a team, and that team delivers working software.
Why we do not offer fixed-bid contracts
Fixed-bid contracts require all requirements to be known and documented before work begins. In practice, requirements change on every project, usually significantly. A fixed-bid contract puts your vendor in the position of arguing that your new requirement was not in the original specification. That dynamic is bad for the project and bad for the relationship.
We prefer transparent time-and-materials engagements where we commit to the monthly team cost and provide a range estimate for the total duration. You decide how much scope to take on and can resize the team or pause the engagement at any time.
Delivering the most important software first
We use an agile development process where the highest-value modules are built first. This means you have working, deployable software early in the engagement, which reduces risk and allows you to validate the product with real users before the project is complete.
