.NET modernization costs: estimate upgrade and architecture
Estimate framework upgrade, cloud readiness, modularisation, tests, CI/CD and modern user interfaces.
.NET modernization costs
Costs for .NET Modernization depend on scope, risk, and quality expectations. The calculator provides an initial range.

FAQ
.NET modernization costs
Upgrade and architecture
What does a .NET modernization cost?
A focused framework upgrade often starts around EUR 24,000 excl. VAT. Modularisation and cloud readiness increase analysis and refactoring effort.
When is an upgrade to current .NET enough?
An upgrade is enough when architecture and business logic are still sound and the main goals are support, security or deployment improvements.
When should a monolith be modularised?
When releases block each other, modules scale differently or changes regularly create unexpected side effects.
Create a .NET roadmap
We review the framework, dependencies and target operations model.
Testing and operations
Why does test coverage affect cost?
Automated tests make behaviour visible and reduce manual regression. Without tests, a safety net must be built before larger changes.
What does cloud-ready .NET include?
Configuration, logging, health checks, containers, automated deployments and decoupled state are prepared for reproducible operations.
How does Groenewold IT deliver .NET projects?
Modernization is delivered Made in Germany in Leer, East Frisia, in measurable stages with direct architecture and operations feedback.
Typical pricing models (overview)
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.
