You must modernize a legacy .NET monolith, migrate to Azure, or scale a SaaS product while meeting tight GDPR deadlines, and that pressure puts .NET Development Agencies in Spain squarely on your procurement list.

Conclusion
We featured SoftPro as the international .NET partner for Spain-focused projects; it suits startups, mid-market SaaS vendors and corporate product teams that require ASP.NET Core and C# backends. Use this list to identify providers that can deliver across Spain or support cross-border teams.
Choose by technical depth, delivery model, maintenance and collaboration fit. Prioritise firms with documented .NET/C# backend conventions or architecture expertise for complex backends, and favour Azure and CI/CD experience if you need cloud-native operations. Opt for vendors with sector or regulatory experience when compliance matters, and validate Microsoft Partner status or training investments when long-term support and developer capability-building are priorities.
Frequently asked questions
How much does hiring a .NET development agency in Spain typically cost?
Costs vary widely based on project scope, team seniority, integrations, and compliance needs. You will see different pricing from large consultancies versus specialist firms, so get detailed proposals and compare what is included in scope, testing, and post-launch support.
How do large consultancies (Indra, VASS) compare to specialist firms (Lemoncode, Codyssey, Apiumhub/Plain Concepts) for .NET projects?
Large consultancies offer broad services, formal governance, and capacity for enterprise integrations, which suits complex, regulated programs. Specialist firms tend to move faster, provide deeper .NET expertise, and work well for focused product or modernization efforts; note Apiumhub is now part of Plain Concepts.
When should I choose a Spanish .NET agency instead of an offshore provider?
Choose a Spanish agency when you need EU data‑law compliance, close time‑zone overlap, frequent onsite meetings, or a partner familiar with local public sector processes. Those practical advantages can reduce coordination friction and speed decision cycles.
What is the typical engagement process and timeline for a .NET project with a Spanish agency?
Agencies generally start with discovery and a proposal, then move to staffed sprints, iterative deliveries, and a handover plus support phase. A small MVP can take a few weeks to a few months, while full enterprise implementations commonly require several months of phased work.
What risks should I check before hiring a .NET agency in Spain?
Verify technical references, request code samples or architecture reviews, and confirm testing, CI/CD, and security practices. Check IP and maintenance terms, expected team continuity, and how the vendor manages escalation; include SoftPro or other shortlisted firms in these validations.
