Before you sign with a software development company, you will choose a contract model. The right model protects your budget and keeps the project flexible enough to succeed. Here is how fixed price, time and materials, and dedicated team models compare.
Fixed price
The scope, timeline and price are agreed upfront.
- Best for: small to medium projects with clear, stable requirements.
- Pros: predictable budget.
- Cons: less flexibility; changes require change requests and may add cost.
Time and materials (hourly)
You pay for the actual time spent, usually with regular reporting.
- Best for: evolving products, R&D and projects where requirements will change.
- Pros: flexibility to adjust priorities at any time.
- Cons: total cost is less predictable, so set budgets and review regularly.
Dedicated team
A team of developers, testers and a project manager works on your product for a monthly fee.
- Best for: long-term products and continuous development.
- Pros: deep product knowledge, stable velocity, full control of priorities.
- Cons: requires active product management on your side.
What every software contract should include
- Scope or backlog and acceptance criteria.
- Milestones, deliverables and payment schedule.
- Ownership of source code and intellectual property.
- Confidentiality (NDA) and data protection.
- Warranty period and support terms.
- Change request process.
- Termination and handover terms.
Writing a good project brief
Describe your business goals, users, main workflows, systems to integrate with, must-have versus nice-to-have features, budget range and target launch date. A clear brief leads to accurate quotes.
Frequently asked questions
Which model is cheapest?

Can I switch models during a project?
Yes. Many clients start with a fixed-price MVP, then continue with a dedicated team or hourly model.
