Software that actually works,
built by people you can reach
Verleij Services develops custom software, websites and mobile apps. You talk directly to the developer. No middlemen, no vague proposals.
Our services
From a simple website to a full software platform. We think along, build solid and deliver what was agreed.
Custom software
Off-the-shelf packages never fit perfectly. We build software tailored to your process, workflow or product. From simple internal tools to complete production platforms.
Web development
Fast, secure and well-indexed. Whether it is a business card site, a landing page or a fully CMS-driven website, we make sure it works on every device and loads quickly.
iOS and Android apps
Native feel, built cross-platform. From a simple informational app to a complex application with push notifications, subscriptions and a backend. App Store and Play Store submission included.
Technical consulting
Which technology fits your situation? How does this scale? Is it secure enough? You get honest, independent advice from someone who also builds it themselves.
Code review
A second pair of eyes on your codebase. We flag bottlenecks, maintenance risks and security issues, then give you concrete improvement points rather than a page of theory.
Security audit and pentest
We find vulnerabilities before attackers do. From configuration check to active penetration test. Result: a clear report with priorities and actionable fixes.
Debugging and problem-solving
Your application is behaving strangely but nobody knows why. We dig down to the root cause. Reproducible, well-founded, and with a fix that holds up in the next release too.
API integrations
Two systems that do not talk to each other yet. We build the bridge: REST, GraphQL, webhooks, existing packages. Robust, documented and with proper error handling.
Why Verleij Services?
There are plenty of software companies. Here is why clients choose us.
Direct line to the developer
You email or call the person who actually writes the code. No account manager in between, no information lost in translation across three departments.
Honest about what is possible
If something is too complex for the budget, we say so. If an off-the-shelf package fits better than custom code, we advise that too. No stretching a project to land a contract.
Years of real-world experience
We have seen the pitfalls. Legacy migrations, real-time sync issues, multi-tenant edge cases. That experience is baked into every project we take on.
Results-driven, not hour-chasing
We work to get things done. You pay for a working result, not endless meetings. And if something overruns because of a mistake on our side, we do not just pile on extra hours.
Portfolio
From open source tools to complete platforms with thousands of users. An overview of projects we have built and maintain.
Frequently asked questions
How much does custom software development cost?
The price depends heavily on the scope and complexity. A simple tool or integration can start at just a few hundred euros; a larger platform requires a more detailed quote. Send us an email describing your idea and you will receive an honest estimate quickly, with no obligations.
Do you also build iOS and Android apps?
Yes. We develop native-feeling, cross-platform apps for both iOS and Android. From a simple informational app to a complex application with push notifications, subscriptions and backend integrations. We handle the App Store and Play Store submission process for you.
What is a security audit or pentest?
A security audit is a systematic review of vulnerabilities in your application or infrastructure: insecure configurations, outdated dependencies, logic flaws and known attack vectors. A penetration test goes a step further: we actively try to exploit vulnerabilities to prove they are real and exploitable. You receive a clear report with prioritised findings and concrete remediation steps.
How do I get in touch?
Send an email to info@verleijservices.nl. You always get a direct reply from the developer, not a helpdesk or sales team. Just an honest conversation about what you need.
