How Long Does Custom Software Take to Build?

Realistic timelines for custom business software development.

One of the most common questions: “How long will this take?” Here’s a realistic guide.

Simple Application (3–5 days)

Single-purpose tool: inventory tracker, basic CRM, staff directory. Core CRUD operations with a dashboard and CSV export.

Standard Application (5–10 days)

Multi-feature system: user logins, automatic email alerts, multiple data views, reporting, and role-based access.

Complex Application (10–20 days)

Enterprise-grade features: multi-site support, API integrations, advanced reporting, document management.

My Process

  1. Day 1: Discuss requirements and agree on scope.
  2. Day 2–3: Working prototype delivered for feedback.
  3. Day 3–7: Full application built, tested, and refined.
  4. Day 7+: Deployed, handed over, and revisions until you’re happy.

The 48-hour prototype means you see progress immediately. No weeks of silence.
