Custom software pricing is famously opaque. You ask three developers for a quote and get three wildly different numbers. This post breaks down the real factors that drive .NET development costs — so you can budget accurately and spot unrealistic quotes.
The Core Variables
Cost is driven by four things: complexity (how many modules, edge cases, and integrations), team size (solo dev vs. team), timeline (faster delivery costs more), and tech stack (some stacks have higher developer rates).
Typical Ranges for .NET Projects
Based on real projects I've worked on: A simple Blazor CRUD web app (3–5 modules, single user type) typically runs $3,000–$8,000. A medium-complexity SaaS platform with auth, roles, notifications, and 3rd-party integrations: $12,000–$35,000. A full enterprise system with multi-tenancy, BI dashboards, complex workflows, and compliance: $50,000+.
What Drives Costs Up
Real-time features (SignalR, WebSockets), third-party API integrations (payment gateways, CRMs, legal platforms), strict compliance requirements (HIPAA, PCI-DSS), and rushed timelines all add significant cost. Each integration is a negotiation — with another company's API, documentation quality, and rate limits.
What Drives Costs Down
Clear requirements upfront, phased delivery (start with MVP), reuse of existing .NET libraries (Hangfire, Syncfusion, ABP.io), and flexible timelines all reduce total cost significantly.
Fixed Price vs. Hourly — Which Is Better?
Fixed price works when scope is clear and well-documented. Hourly works for ongoing work, consulting, or projects where requirements evolve. I typically offer fixed price for defined projects and a monthly retainer for ongoing development support.
