When you hire a software development company, you're choosing two things: who builds your product, and how you pay for it. The second choice quietly decides your budget, your flexibility, and how much friction you'll feel along the way.
There are three main engagement models. Here's how each one works, what it really costs, and when to use it.
At a glance
| Fixed Price | Hourly (Time & Materials) | Dedicated Team | |
|---|---|---|---|
| Best for | Clear, stable scope | Evolving requirements | Long-term roadmaps |
| Budget certainty | High | Medium | High (monthly) |
| Flexibility | Low | High | High |
| Your involvement | Low–medium | Medium–high | High |
| Typical duration | Weeks to a few months | Any | 6+ months |
Fixed price: certainty for well-defined work
You agree on a detailed scope, timeline, and total price before work starts. Payments are usually tied to milestones.
Works best when:
- The requirements are clear and unlikely to change
- It's a contained project: a marketing website, a defined feature, a small app or MVP
- You need a firm number for budgeting or approvals
Watch out for:
- Built-in risk buffers. Vendors price in uncertainty, so you may pay for risks that never happen.
- Change requests. Every new idea becomes a negotiation and an extra cost.
- Rigidity. If you learn something new mid-project, changing direction is slow.
Tip: Fixed price only works with a detailed, written scope. Invest in a proper discovery phase first.
Hourly (time and materials): flexibility as you learn
You pay for the actual hours worked, typically with weekly time reports. Priorities can change every sprint.
Works best when:
- Requirements are still evolving
- You're iterating based on user feedback
- The work is ongoing improvements, maintenance, or integrations
Watch out for:
- Less budget certainty unless you set caps
- Needs your attention — someone on your side must prioritise and review regularly
Tip: Agree on a monthly budget cap and review working software every week. That gives you flexibility without surprises.
Dedicated team: your own engineers, without the hiring
You get one or more engineers working full-time on your product for a fixed monthly cost. They join your tools and processes, and build deep knowledge of your business. The development company handles recruiting, payroll, equipment, and replacements.
Works best when:
- You have a long-term product roadmap
- You need steady capacity rather than a one-off project
- You want engineers who understand your product deeply
Watch out for:
- You manage priorities. It's your team — it works best with clear product ownership on your side.
- Short projects don't suit it. For a few weeks of work, fixed price or hourly is simpler.

Which model saves the most money?
It depends on how well you know what you're building:
- You know exactly what you need → Fixed price avoids paying for uncertainty you don't have
- You're still discovering what users want → Hourly avoids paying for change requests and rework
- You're building and improving a product for the long haul → Dedicated team gives the lowest cost per hour of real output, because the team keeps its knowledge and momentum
The most expensive choice is a mismatch — like forcing a fixed-price contract onto a product that's still changing every week.
A common, effective path
Many successful products combine models over time:
- Discovery and MVP on fixed price — clear scope, clear budget, fast launch
- Hourly after launch — iterate quickly based on real user feedback
- Dedicated team as you scale — steady capacity for a growing roadmap
How Brahmweb works
Brahmweb offers all three models — fixed price, hourly / T&M, and dedicated developers — and you can switch between them as your project evolves. Every engagement includes weekly demos, code review on every pull request, and a written paper trail at every stage, so you always know what you're paying for.

Frequently asked questions
Is fixed price cheaper than hourly?
Not necessarily. Fixed-price quotes include a buffer for risk, and every change request adds cost. For clearly defined projects it gives budget certainty; for evolving products, hourly often ends up cheaper because you only pay for work actually done.
When should I choose a dedicated team?
When you have a long-term product roadmap, ongoing development needs, and want engineers who build deep knowledge of your product. It's usually the most cost-effective model for work lasting six months or more.
Can I switch engagement models later?
With a flexible partner, yes. A common path is a fixed-price MVP, then moving to hourly or a dedicated team once the product is live and requirements keep evolving.
How do I control costs on an hourly project?
Ask for weekly time reports, agree on priorities every sprint, set a monthly budget cap, and review working software in regular demos so effort always matches value.
