Let me say something uncomfortable.
Most “Fixed Price” projects are not really fixed.
And most “Time & Material” projects are not really flexible.
They’re just risk-transfer mechanisms dressed up as pricing models.
Here’s what software agencies rarely say out loud.
The Fixed Price illusion
When a client demands absolute certainty, agencies quietly add a “risk buffer.”
- Ambiguity gets priced in.
- Unknowns get priced in.
- Future arguments get priced in.
You aren’t paying for development. You’re paying for uncertainty insurance. And the moment the scope changes? That’s when the real negotiation begins.
The Time & Material trap
Clients think T&M means transparency.
Agencies think it means protection.
But here’s the truth:
- If requirements are weak, T&M becomes an open tap.
- If governance is weak, burn rate replaces discipline.
It’s not flexible. It’s unmanaged risk.
The part nobody discusses in digital transformation meetings
The pricing model doesn’t determine a project’s success. Risk clarity does.
Before you choose between Fixed Price or T&M, ask these 5 questions:
- How mature are the requirements?
- How stable is the product vision?
- Who actually controls change requests?
- Is the technology stack proven for this use case?
- Who absorbs the cost of integration failures?
Traditional engineering disciplines learned this the hard way decades ago. In custom software development, we are repeating the same mistakes.
If you are a software agency, be honest about risk.
If you are a client, stop shopping for pricing models and start shopping for clarity.
Because in IT services, pricing is never just about money.
It’s about who carries the uncertainty.
