FAQs
Q: What is the average cost of B2B software development in 2026?
A: In 2026, costs are driven by AI complexity and integration depth. A standard B2B MVP typically starts at $75,000, while enterprise-grade platforms featuring multi-agent systems (MAS) or custom LLM integrations often range from $250,000 to over $1,000,000.
Factors such as high-fidelity UI/UX, serverless cloud-native architecture, and stringent 2026 cybersecurity compliance heavily influence the final quote.
Q: How do I verify an agency's AI capabilities?
A: Ask for their AI-SDLC (Software Development Life Cycle) framework. A top-tier agency in 2026 should use AI for automated testing, documentation, and code refactoring, which can increase delivery speed by up to 40%.
Q: Should I choose a local or nearshore agency?
A: If you need deep collaborative discovery sessions, local is best. If you have a clear roadmap and need to scale engineering capacity cost-effectively, nearshore is the modern standard.
Their primary difference remains time-zone alignment. Nearshore (if US companies are hiring from Latin America) offers real-time collaboration for Agile sprints. Offshore (if hiring from Southeast Asia or Eastern Europe) remains the most cost-effective for large-scale engineering, provided the agency has a robust 24/7 communication model.
Q: How do I protect my Intellectual Property (IP) during development?
A: Strict legal frameworks are essential. Ensure the agency signs a comprehensive Master Services Agreement (MSA) and a Non-Disclosure Agreement (NDA) that explicitly states all source code, data, and logic are your sole property upon payment.
In 2026, specifically check for clauses regarding AI-generated code ownership to ensure your unique algorithms remain legally protected.
Q: Why is Platform Engineering important for my B2B software?
A: Platform Engineering is the 2026 gold standard for scalability. It involves building an internal developer portal that automates infrastructure and security checks. By choosing an agency that prioritizes this, you ensure that you have a standardized, secure ecosystem that your internal team can easily maintain and update without needing constant agency support.
