An employee salary and a development quote cover different things. Before comparing them, write down the same release scope, review requirements and support period for both options.
Build two complete estimates
For an internal team, include recruitment, onboarding, tools and the time existing staff will spend on management and review. For an external team, include discovery, delivery, acceptance testing, your own coordination time and any work excluded from the quote.
Keep assumptions visible. A fixed price based on settled requirements cannot be compared directly with a monthly team budget for an evolving backlog.
Ask what changes the estimate
- Who pays for investigation when an existing integration behaves differently from its documentation?
- How are changes to scope estimated and approved?
- Are deployment, documentation and handover included?
- What happens if a key reviewer or dependency is unavailable?
- What support is included after acceptance?
Compare a delivery plan, not just a rate
A lower hourly rate does not tell you the required hours, review effort or likely rework. Ask each option to explain the first deliverable and the assumptions behind its schedule. Where uncertainty is high, estimate a limited discovery phase separately.
Use your actual staffing costs and supplier proposals. This article provides a comparison method, not market salary benchmarks or a promise that one model will be cheaper.
