Pricing
Software development pricing and engagement models
Software projects are usually priced in one of four ways: fixed price, time and materials, milestone billing or a dedicated team. The right choice depends on how well your scope is defined and how much change you expect.
How software development pricing works
There is no single price for software; cost follows scope, complexity and timeline. What you can choose is the pricing model, which decides who carries which risk. Stackvala offers four models and helps you pick the one that matches how clear your requirements are.
Pricing models compared
| Model | Best for | How it works | Watch out for |
|---|---|---|---|
| Fixed price | Well-defined projects with stable scope | Agreed scope, timeline and total price | Changes need a formal change request |
| Time and materials | Evolving products and discovery-heavy work | Billed for effort at agreed rates, with a budget cap if wanted | Needs active prioritization to control spend |
| Milestone billing | Phased projects | Payments tied to delivered milestones | Milestones must be clearly defined |
| Dedicated team | Ongoing product development | A team assembled for your roadmap, billed on a recurring basis | Best value over months, not weeks |
Key points
What drives cost
Scope
Number of user roles, screens, workflows and reports.
Integrations
Each third-party or legacy connection adds design and testing.
Compliance
healthcare and financial requirements add controls and documentation.
Design depth
Research-led, custom design takes longer than a standard interface, see UI/UX design.
Platforms
Web only versus web plus iOS and Android.
Timeline
Compressed schedules need larger teams.
Quality level
Test automation and security reviews are investments that reduce later cost.
How to reduce risk and control budget
- Start with an MVP to validate before building everything.
- Prioritize ruthlessly: separate must-have from nice-to-have.
- Use a paid discovery phase for complex or unclear projects.
- Set a budget cap or milestone checkpoints on time-and-materials work.
- Keep one decision-maker on your side to avoid scope drift.

Contact StackvalaHow much does custom software cost?
It varies widely with scope, integrations and compliance needs. After discovery, we provide a written estimate with options so you can compare.
Is a fixed price always cheaper?
Not necessarily. Fixed price transfers some risk to the vendor, which is priced in. It suits well-defined work; evolving products often fit time and materials better.
Do you require a deposit?
Payment terms are set in the agreement and depend on the model. We agree them in writing before work starts.
Are there hidden costs?
We list assumptions and exclusions in the estimate. Typical separate costs include cloud hosting, third-party licences and app store fees.
Can I change the model later?
Often yes. Clients commonly begin with a fixed-price MVP and move to a dedicated team or support plan.
