Fixed-Price vs Hourly Software Development: Which Protects Your Budget?
Who carries the risk under each pricing model, when each one makes sense, and what to check before you sign.
When you hire a team to build software, the pricing model matters almost as much as the price. It decides who pays when the work takes longer than expected. There are two common models, and each suits a different kind of project.
How hourly billing works
You pay for the time spent. The team gives an estimate, tracks hours, and invoices what was used. If the work takes longer, you pay more. If it takes less, you pay less.
Good for: ongoing work, maintenance, research, and projects where the scope will change as you learn.
The risk: the budget is open-ended. An estimate is not a commitment, and you carry the cost of every surprise.
How fixed-price works
You agree on a scope and a price before work starts. If the work takes longer than the team planned, that is their cost, not yours.
Good for: projects with a clear goal and a defined set of features: a web app, a mobile app, an integration, a redesign.
The risk: anything not written in the scope is a change, and changes are priced separately. A vague scope leads to disputes.
Side by side
| Hourly | Fixed price | |
|---|---|---|
| Who carries overrun risk | You | The team |
| Budget certainty | Low | High |
| Flexibility to change scope | High | Lower, changes are quoted |
| Upfront planning needed | Little | A written scope |
| Best for | Open-ended or evolving work | Defined builds |
What makes fixed-price work
- A written scope. Deliverables, timeline and price in one document, agreed before the first invoice.
- A revision allowance. A set number of revision rounds, so feedback has a place in the plan.
- Regular demos. Seeing working software every week catches misunderstandings while they are cheap to fix.
- A clear rule for changes. New ideas are welcome, and they get their own quote.
Questions to ask before you sign
- What exactly is included, and what is not?
- How many revisions are included?
- What happens if the deadline is missed?
- How are changes priced?
- Who owns the code when the project is paid for?
How we price
We work fixed-price. Every project starts with a discovery call, followed by a written scope with deliverables, timeline and price. Our custom web app development packages start at $800 and mobile app development at $4,500, each with a written scope and a weekly demo.
Quick answers
What is the difference between fixed-price and hourly software development?
With hourly billing you pay for the time spent, so the budget is open-ended. With fixed-price you agree a scope and a price before work starts, and overruns are the development team's cost.
Which pricing model protects the client's budget?
Fixed-price gives the most budget certainty because the team carries the overrun risk. Hourly billing is more flexible but leaves the client paying for every surprise.
What does a fixed-price software project need to work?
A written scope listing deliverables, timeline and price, a set number of revision rounds, regular demos of working software, and a clear rule that changes are quoted separately.
