How Software Dev Shops Lose Margin

Running a profitable software agency or engineering consultancy requires continuous awareness of the difference between nominal billing rates and effective realized rates.

Most dev consultancies face three primary sources of margin erosion:

  • Uncontrolled Scope Creep: Small client requests and revisions that are never formally billed, eating into developer hours.
  • Tooling Overhead Stack: Paying $50โ€“$100/user/month across fragmented tools (Jira, Confluence, Harvest, HubSpot, Zephyr) instead of lean platforms.
  • Timesheet Lag: When developers log hours days or weeks late, project managers fail to catch budget overruns until the milestone is already unprofitable.

Formula for Realized Hourly Rate

The realized hourly rate represents the true dollar value generated for every hour an engineer spends working on a client account:

Realized Hourly Rate = Total Client Revenue รท (Planned Hours + Unbilled Scope Creep Hours)

Frequently Asked Questions

What is a good gross margin for a software development agency?

Top-performing engineering agencies target a 55% to 65% gross margin on core development services, leaving enough buffer for operating expenses, sales commissions, and profit distributions.

How does Klority help software consultancies track margins?

Klority unites the entire agency workflow: CRM pipelines track deals, Sprint Kanban tracks deliverables, built-in timesheets track developer hours, and project invoicing calculates real-time profit margins automatically.
