Flexible engagement models
Choose how you want to work with us based on where your product is today. We can help you validate, ship and then scale without forcing you into a one-size-fits-all model.
Fixed-scope projects
Best when requirements are clear and we can estimate precisely.
- Clearly defined scope, milestones and deliverables.
- Predictable budget with upfront estimates.
- Ideal for MVPs and discrete feature releases.
Works well when we have good documentation, visual references or can run a short discovery to lock requirements.
Dedicated product squad
A cross-functional team that behaves like your in-house product team.
- Stable team for long-term ownership and roadmaps.
- Capacity planned monthly with clear velocity.
- Founder involvement on architecture and key decisions.
Ideal when software is core to your business and you need a reliable, senior team without adding full-time headcount immediately.
Time & material / Agile
Ideal for ongoing iterations, R&D and integrations.
- Pay for actual engineering and design time used.
- Flexible backlog and scope, prioritised every sprint.
- Perfect for experiments and proof-of-concepts.
Works well once we have an established relationship and steady flow of work where agility matters more than fixed scope.

Contact our expertsWhat kind of software development projects does QalbIT take on?
We typically work on custom web and mobile applications, SaaS products, internal tools, integrations and platform modernisation. If software is core to your business or operations, we are usually a strong fit.
How do you estimate budget and timelines for a project?
We start with a short discovery call to understand goals, scope and constraints. For well-defined requirements we provide a fixed-cost estimate with milestones. For evolving products, we recommend a monthly or time & material engagement with a clear range and regular checkpoints so you keep control of budget and priorities.
Can you work with our existing codebase and infrastructure?
Yes. We usually begin with a code and infrastructure review to understand the current state, risks and opportunities. Based on that, we propose a stabilisation and improvement plan before adding new features, so we do not build on an unstable foundation.
Which technologies do you use for web, mobile and cloud projects?
We primarily work with modern PHP, JavaScript and mobile stacks including Laravel, Node.js, React, Next.js, Vue.js, Flutter and cloud platforms such as AWS and DigitalOcean. We select the stack based on what is best for your product, team and long-term maintainability.
How does communication and project management work with QalbIT?
You get a dedicated point of contact, a clear communication rhythm and access to our task board. We align on weekly or bi-weekly check-ins, share demos regularly and keep you updated with concise status reports so you always know what is happening next.
