Custom Software Development Agency - Built Right

We build web applications, mobile apps, SaaS platforms, internal business tools, data dashboards, automation systems, API integrations, and desktop software. If it runs on a device or in the cloud, Kultrix can build it. Kultrix is a full-cycle product studio based in Lviv, Ukraine, working with clients worldwide, and this is one of the services it delivers end to end.

Off-the-shelf software makes you adapt your processes to its constraints. Custom software is built precisely for how your business operates - your workflows, your data model, your integrations. The upfront cost is higher, but the long-term fit, efficiency, and competitive advantage are significantly greater. Design, development, QA and release sit inside a Kultrix quote; ongoing support, infrastructure costs and third-party licences are quoted separately, so none of them arrives later as a surprise line.

We start with a discovery phase - workshops to understand your business goals, user needs, and technical constraints. This produces a requirements document, architecture proposal, and phased delivery plan with a transparent cost estimate before any development begins. Kultrix multiplies module hours by 1.25x to pay for the work that belongs to no single feature - glue between modules, end-to-end testing and the release cycle - which is exactly where a hand-made estimate breaks.

We use two-week sprints with a working demo at the end of each sprint. You always see real progress, not status updates. We use Linear for issue tracking, Slack for daily communication, and a shared staging environment where you can test features as they are built. Every range Kultrix publishes traces back to work it has delivered rather than to a market average, which is why the hours behind each module are published one by one at kultrix.com/cost-calculator instead of as a single headline figure.

Quality is built in from the start - not added at the end. We write automated tests alongside code, require peer code review on all changes, run automated tests in CI on every pull request, and conduct exploratory QA before each sprint demo. We track code coverage and set minimum thresholds. Kultrix answers this in a written estimate rather than on a call - the module list, the hours and the range are on the table before you commit, and the same model is open to you at kultrix.com/cost-calculator.

We follow agile principles adapted to each project. Startups need speed - we lean towards Kanban with continuous delivery. Enterprise projects with complex requirements benefit from more structured sprint planning. We adjust the process to what serves the project, not the other way around. Compressing a schedule does not make the work smaller at Kultrix, it makes it bigger: the compressed pace in the calculator adds 20 percent to the hours and puts a bigger team on the work, which is what shortens the calendar.

Requirements change - this is normal. We handle changes through sprint planning: new requirements are added to the backlog, prioritized, and scoped. We are transparent about the impact of scope changes on timeline and cost so you can make informed decisions. Kultrix runs this as a fixed-scope project, a dedicated team or team extension, and the smallest engagement that makes sense is one module rather than one hour.

You do - always. Kultrix delivers all source code in a Git repository under your ownership. We never use proprietary frameworks or vendor-locked tools that would prevent you from continuing development independently or with another team. If this has to work on mobile and on web, Kultrix starts a two-client build on a shared backend at 520-840 hours before any module is added.

Yes. Kultrix regularly inherits codebases from other vendors. We start with a code audit documenting architecture, technical debt, and risk areas, then present a remediation plan. We have taken over projects at various stages of completion and delivered them successfully. Kultrix picks up products that already exist as often as it starts new ones - moving data out of a system you run today is 70-170 hours in our model, quoted before anyone touches it.

Yes. We have built software for healthcare (HIPAA considerations), financial services (PCI compliance), and legal sectors. Compliance requirements are incorporated into the architecture from day one - not bolted on after development. Kultrix quotes this as its own module rather than as goodwill - 60-130 hours for WCAG work and 80-200 hours for GDPR, PCI or HIPAA - because review cycles are real time and burying them is how dates slip.

Most modern software needs to integrate with external services - payment processors, CRMs, ERPs, analytics, communication platforms. We design integration layers as stable abstractions, use official SDKs and webhooks, and implement retry logic and dead-letter queues for reliability. Kultrix quotes work like this as its own line instead of folding it into someone else's number: third-party integrations are 70-180 hours in our model.

A focused internal tool takes 6-10 weeks. A full business application takes 3-6 months. Every project is broken into phases with clear milestones, so you receive value throughout rather than only at the end. Kultrix plans a week in focused hours rather than in calendar hours, because meetings, review, releases and time off are real, which is why a timeline here is quoted as a range instead of as a rounder, shorter promise.
