Why choose an affordable B2B web app development agency
Cost matters, but so does quality. Here is what IRPR delivers at our price point.
IRPR has shipped over 200 B2B web apps for clients in 50+ countries. Our fixed price model means you know the cost before we write a line of code. No hourly billing, no scope creep fees.
We use modern stacks like Next.js, Node.js, and PostgreSQL to keep build times short and maintenance low. Every app passes automated security scans and load testing before launch.
How IRPR compares to other agencies
Most agencies quote high and deliver late. Here is the difference.
We price projects at $80K-$250K with a fixed scope. Other agencies often start at $150K-$300K with hourly billing and no cap.
Our engineers are senior only. We skip junior developers who need training. This keeps velocity high and bugs low.
