# Engagement models — Devinity Solutions LLC Devinity quotes against defined scope, fixed in writing after a scoping call. The bands below are ranges from delivered work of the same shape — published so the cost of an engagement can be evaluated without a sales conversation. Last updated: 2026-08-07 ## Price bands ### Focused tool — $5k – $12k, 3–5 weeks - One job, done properly, integrated with what you already run. The fastest way to find out whether custom software pays for itself in your business. ### Core system — $12k – $28k, 6–10 weeks - The system a department works in every day, with the roles, permissions and reporting that implies. ### Platform — $28k – $60k, 3–5 months - Multiple user types, external access, and the operational hardening a system needs when revenue depends on its uptime. Most first builds land in the $5k – $12k range. Custom software costs a fraction of what it did a few years ago — a system quoted at $60,000 in 2019 is $12,000 to $18,000 today — and these bands reflect that being priced through rather than kept as margin.
