Custom Software Development
Custom software that adapts to your business, not the other way around. Automate processes, connect systems, and eliminate inefficiencies that hinder your growth.
Software That Works The Way You Work
Does your business rely on Excel spreadsheets, manual processes, or systems that don't communicate with each other?
Generic software forces you to change the way you work. Custom software does the opposite: it's designed around your processes, your team, and your goals.
For over a decade, we've been developing custom software for companies that had reached their limits with off-the-shelf solutions. Management systems that eliminated weeks of manual work. Platforms that connected legacy ERPs with modern tools. Applications that transformed chaotic processes into automated workflows. What they all have in common: each one solved a specific problem that no off-the-shelf software could address.

From Your Problem to Your Solution
Our custom software development process begins with understanding your business, not writing code. Every technical decision is driven by a business objective.
-
Process Analysis
We map your current operations to identify bottlenecks and automation opportunities. We understand how your team works before proposing solutions.
-
Solution Design
We define the custom software architecture: which systems to connect, which processes to digitize, and which API integrations are necessary. We prioritize features based on their impact on your efficiency .
-
Prototyping and Validation
We design interfaces and workflows that your team validates before development. We detect conceptual errors when correcting them is inexpensive, not after the software is already built.
-
Iterative Development
We build in cycles. You see real progress from the start: working software, not presentations. You can adjust priorities as your business evolves.
-
Integration with your systems
We connect your new custom software with CRM, ERP , and any existing system. If you work with legacy systems , we develop API integration layers that modernize without replacing them.
-
Deployment and Training
We implement on your infrastructure or in the cloud. We train your team to take full advantage of every feature. Software only generates value when it's used.
-
Continuous Evolution
Your business changes, and so does your custom software . Maintenance, new features, adaptation to new processes. We grow with you.
Why Mecexis for your Custom Software Development
We don't sell programming hours. We solve business problems.
Custom software development isn't about technology: it's about understanding what your company needs and building exactly that. Nothing more, nothing less.
We've helped companies eliminate processes that consumed days of manual work through intelligent automation . We've connected systems that hadn't communicated for years, unlocking data that no one could use. We've modernized legacy systems without forcing them to discard what was working.
We work with Django, the Python framework used by Instagram and Spotify when they need scalable systems. But what sets us apart isn't the technology: it's that every line of code addresses a real problem in your business. No over-engineering, no features no one will ask for. Custom software means exactly that: tailored to your needs.
A single team develops your backend, your frontend, and manages your infrastructure. When something goes wrong, there's no finger-pointing between vendors. We diagnose, fix, and follow through.

Frequently Asked Questions
Direct answers about custom software development .
What You Need to Know Before You Decide
-
1
When does it make sense to invest in custom software instead of using SaaS?
-
When your process is your competitive advantage and you don't want to adapt it to generic software. When you've tried several tools and none of them fit. When you need integration between systems that don't communicate. When the cost of inefficiency exceeds the cost of development.
-
2
How much does custom software development cost?
-
It depends on the complexity. Automation or digitization projects for specific processes can start at €25,000-€40,000. Complete platforms with multiple integrations and users typically range from €60,000 to €150,000. We'll provide you with a fixed price quote after analyzing your needs.
-
3
How long does a typical project take?
-
An automation system or specific module can be in production in 2-3 months. More complex platforms with CRM/ERP integration and multiple functionalities require 4-8 months. We work in sprints with constant deliveries: you'll see progress from week 2.
-
4
Can you integrate with our current ERP/CRM?
-
Yes. We've worked with many ERP and proprietary systems. If your system has an API, we'll connect it. If it doesn't, we'll develop an API integration layer. We also modernize legacy systems by adding modern interfaces without replacing the core.
-
5
What happens if our requirements change during the project?
-
That's normal. We use agile methodology precisely for this reason: we review priorities and make adjustments every two weeks. Your custom software evolves based on what you learn during development.
-
6
What guarantee do we have that it will work in the long term?
-
We develop with Django, a framework with 20 years of evolution and used by companies that serve millions of users. Our code is well-documented, tests are automated, and our architecture is designed for easy maintenance. We offer support and upgrade agreements to protect your investment.
-
7
Can you maintain or improve software developed by another company?
-
Yes, although it depends on the state of the code. We audit the system, evaluate its quality, and give you an honest diagnosis: whether it makes sense to keep building on it or if it's more efficient to rewrite parts of it. Sometimes inheriting bad code costs more than starting clean.
