We take over the continuous maintenance and care of your software solutions. Through regular updates and optimizations, we keep your systems up to date.
Regular Updates & Patches
Keep your software secure and up to date.
Feature Enhancements
Continuous improvement and extension of functionality.
Bug Fixing & Support
Quick response to problems and issues.
Knowledge & Answers
Security updates, bug fixes, performance optimizations, small enhancements, monitoring, and technical support. Optionally also 24/7 on-call service. We define the exact scope together in an SLA.
Yes, after an audit. We review quality and security before taking responsibility for operation. If the code is too problematic, we advise on alternatives.

Assessment of your software?
We check what maintenance effort your system requires.
Thorsten Frieling – Project Management
Usually a monthly flat rate or time & materials. Predictable costs prevent nasty surprises during outages. Packages start at around €500/month for smaller applications.
Flexibly negotiable – from monthly cancellation to multi-year contracts with discount. Most customers choose 12-month contracts with fixed monthly rates and defined SLAs.

Need a maintenance quote?
We create you an individual SLA offer.
Björn Groenewold – CEO
We agree on SLAs (Service Level Agreements) that guarantee response times – up to 24/7 support for critical systems. Standard: 4-8 hours during business hours.
Yes, maintenance and development go hand in hand. We make sure your software grows with your business. Small changes are often included, larger ones are quoted separately.
Regular security updates, dependency monitoring, vulnerability scans, and proactive patches. We keep an eye on your system and act before attackers can exploit vulnerabilities.
Knowledge about old systems is often lost. We systematically document and build knowledge transfer so your software doesn't depend on individual people.

Want reliable maintenance?
Let's discuss your requirements for long-term care.
Thorsten Frieling – Project Management
Software does not stop needing attention after deployment. Operating systems release security patches, programming language runtimes deprecate features, and third-party libraries disclose vulnerabilities that require immediate action. Without proactive maintenance, applications accumulate technical debt that makes every future change slower and riskier. Our maintenance services ensure your software stays healthy, secure, and compatible with evolving infrastructure requirements throughout its entire operational lifetime.
Our maintenance engagements begin with a thorough audit of your application stack, identifying outdated dependencies, known security vulnerabilities, and architectural bottlenecks. We establish automated monitoring for dependency updates and CVE disclosures, enabling us to apply critical patches within hours rather than weeks. Regular health checks assess database performance, memory utilization, and response times to catch degradation before it affects your users or triggers costly emergency interventions.
Beyond keeping the lights on, effective maintenance includes continuous improvement. We analyze error logs and user feedback to identify recurring pain points, then prioritize small enhancements that deliver outsized impact. A streamlined form field here, a faster search query there, incremental performance tuning month over month. These steady improvements compound over time, extending the productive lifespan of your software investment and delaying the need for expensive rewrites or replacements by years.
Knowledge continuity is one of the most undervalued aspects of professional software maintenance. When your internal team changes or the original developers move on, critical understanding of system behavior can evaporate overnight. We systematically document architecture decisions, deployment procedures, and business logic as part of every maintenance contract. This living documentation ensures that your software remains understandable and maintainable regardless of personnel changes, protecting your organization from dangerous knowledge silos.
Frequently Asked Questions
Monitoring, dependency updates, security patches, bug fixes and optional enhancements. We document architecture and procedures so your software stays understandable and maintainable.
Typically 10–20% of development cost per year; small applications from around €300/month excl. VAT. We tailor SLAs and scope to your risk and budget.
For business-critical software, yes. Without it, security gaps and technical debt grow and every change becomes riskier and slower.
Yes. We audit the stack, document what we find and then maintain or improve it. Knowledge transfer and runbooks are part of our handover.
