No problem. We develop and publish your extension on Microsoft’s **AppSource** platform. ### Tech Debt Analysis: Uncovering the hidden costs and risks of tech debt. Individual adaptations often lead to confusing complexity and high follow-up costs – a classic example of technical debt (tech debt). This arises from unstructured developments that become difficult to maintain over time. Especially in M&A transactions, it is crucial to clearly understand the risks and costs of the existing system. We provide a comprehensive analysis of your NAV/Navision system, identify tech debt and assess potential impacts. This gives you full transparency and a sound basis for making your next move.
