Frequently Asked Questions
Do you provide .NET staff augmentation, or project-based development?
We deliver project-based engagements with a dedicated onshore team, not hourly staff augmentation. If your legacy .NET system needs a long-term technical partner rather than a contractor to fill a seat, that's the fit we're built for.
How much does custom .NET development cost?
Most engagements begin around $25,000 for a focused build or assessment. Larger modernizations, multi-system integrations, or enterprise platforms can extend well into six figures depending on scope and compliance requirements.
How long does a .NET development project take?
Timelines vary by scope. A focused application build or integration often runs three to six months; larger modernizations of legacy .NET Framework systems extend longer. We deliver in phases so you see working software early.
