Frequently asked questions

How much does custom software development typically cost?

Custom software development pricing varies widely based on scope, complexity, and agency location. Smaller projects or MVPs can start around ten thousand dollars, while comprehensive enterprise systems often exceed fifty thousand dollars or require custom pricing.

What is the difference between staff augmentation and a turnkey project?

Staff augmentation involves hiring external developers to integrate directly into your existing in-house team. A turnkey project means the agency takes full responsibility for managing, designing, and delivering the entire software solution from start to finish.

How long does it take to build a custom software application?

A basic minimum viable product can take between two to four months to develop. More complex enterprise software solutions with extensive integrations and stringent security requirements can take six months to over a year.
