FAQ — software development services
What are “software development services” in practice?
We design, build, integrate, and maintain software tailored to your processes — from internal systems and APIs to mobile apps and websites.
How much does custom software cost?
It depends on scope and integrations. After a short free consultation we provide a realistic estimate and delivery plan.
Do you work hourly or fixed price?
Both are possible. For unclear scopes we usually start hourly (audit / prototype), then move to a fixed scope and milestones.
Can you improve an existing system?
Yes. We often take over existing codebases, stabilize them, and deliver new features in safe increments.
Are you based in Lithuania? Can you work remotely?
Yes — we’re based in Kaunas, Lithuania, and we work remotely with clients in Lithuania and abroad.
How fast can we start?
Usually within days. First we clarify the goal, constraints, and define the next concrete step (audit, prototype, or MVP).
Do you provide support after launch?
Yes — monitoring, bug fixes, and ongoing development as your product grows.
