FAQ
Frequently Asked Questions
How can I tell if I need custom web development rather than a template?
Custom development is needed if a website must perform business functions: generate leads, automate processes, integrate with a CRM, or scale. If you need a temporary or very simple web site, a template may be sufficient.
Can I start with minimal functionality and expand the product later?
Yes, we often start with a basic version (MVP or core functionality). The project architecture is designed from the start to allow seamless addition of new features in the future.
How involved will I be in the development process?
You are involved at key stages: strategy, design, and interim results. At the same time, you don’t need to control every detail - we manage the process and provide regular progress updates.
Can the website be adapted if the business model changes in the future?
Yes. Custom architecture allows changes to the structure, logic, or functionality of the web site without a complete product rebuild.
What happens if requirements change during development?
We work flexibly: we assess the changes, agree on their impact on timelines and budget, and adapt the plan. This allows us to maintain control and predictability even when requirements change.
Is your development suitable for active marketing and advertising?
Yes, web sites are prepared from the start for ad traffic, analytics, and A/B testing. This enables effective marketing campaigns and scalable results.
Who owns the code and the final product after the project is completed?
After the website development is completed, you fully own the code, design, and all deliverables. There are no hidden limitations or dependencies.
Can I order only part of the work (for example, an audit or UX)?
Yes, you can start with individual services such as an audit, strategy, UX/UI, or technical consultation without a full development cycle.
What does post-launch support look like?
We can provide technical support, feature development, performance optimization, and assistance with scaling according to your business needs.
