How long does custom software take to build?

Custom software development timelines range from 6 weeks to 12+ months.

A simple MVP or internal tool takes 6–12 weeks. A mid-complexity application with multiple features and integrations takes 3–6 months. Large-scale platforms with complex workflows and extensive testing take 6–12+ months. The timeline depends on scope, complexity, team size, and how quickly decisions and feedback are provided. Building in phases (MVP first, then iterations) is faster and less risky than trying to build everything at once. At MooseBase, we use agile development to deliver working software in 2-week sprints, so you see progress continuously.
