Three developers. Three estimates. Which one is right?
Why does software pricing always feel like a guessing game?
01｜A Real Scenario
A client asks: “How long does it take to build a login feature?”
- Developer A: 2 days
- Developer B: 5 days
- Developer C: 8 days
👁
Who’s correct?
Actually, all of them — but they have different definitions of “done.”
A only counted coding time.
B included database, encryption, and API integration.
C also considered password reset, security, and error handling.
The real problem? No shared understanding of what “done” means.
02｜Why Estimates Differ So Much
On the surface: different experience, tools, and speed.
But underneath, three root causes:
1. Unclear Requirements
“Build an admin panel” or “a platform like Amazon” — vague scope leads to vague estimates.
2. No Standard Unit
Housing has price per square meter.
Software has... gut feeling.
3. Hidden Complexity
What looks like “just a button” often involves databases, security, permissions, and edge cases that no one accounts for upfront.
Software projects don’t have a “per square meter” pricing model.
03｜Is There a Scientific Approach?
Yes.
COSMIC Function Points is an internationally recognized standard for software sizing — used for nearly 30 years.
How It Works
- No guessing by “person days”
- Measure functional size using a consistent method
- Each function point represents a data movement or business operation
What It Solves
- Common language — clients and developers align on scope
- Historical data — use past projects to calibrate estimates
- Comparability — estimates become comparable across developers
In short: it turns fuzzy requirements into measurable numbers.

04｜How to Improve Estimation Accuracy
| Phase | Practice |
|---|---|
| Requirements | Use functional sizing to clarify scope |
| Estimation | Combine historical data with team velocity |
| Delivery | Compare actual vs. estimate and refine |
| Tooling | Let tools track data instead of “gut feeling” |
These steps aren’t complicated — but they require consistency and data.
05｜What Scope Labs Is Doing
We’re building tools to make this workflow practical.
Scope Labs helps software teams and freelancers estimate with confidence:
- Input requirements → AI helps identify function points
- Apply COSMIC standards → get functional size
- Combine with team historical velocity → generate estimate range
- Continuous learning → the system gets smarter over time
Our goal: make software estimation as transparent as renovation.
No more guessing games.
Final Thoughts
Software estimation will never be 100% accurate — but it can be predictable.
When we stop guessing and start measuring,
everyone wins: clients feel confident, developers get fair value, and projects stay on track.
