Custom Software Development

We build complex, production-grade software systems for organizations where downtime, data loss, or a failed launch are not acceptable outcomes — from national-scale government portals to business-critical enterprise platforms.

Who this is for

You're replacing a legacy system nobody dares to touch

A business-critical system has grown for years, the original authors are gone, and every change is a risk. You need it modernized without taking production down.

A previous vendor over-promised on a fixed bid

The project ran over budget, missed deadlines, or shipped something that didn't fit. You want transparent delivery and a partner who stays accountable.

The system has to survive an audit

Security, legal, or a regulator will review what you build. You need documented architecture, traceable decisions, and compliance handled from day one — not bolted on later.

You need a system that outlives the vendor

You want the source code and the know-how, to avoid lock-in, and to be able to operate or hand over the system long after the project ends.

What We Build

  • Government portals and citizen-facing platforms at national scale
  • Enterprise SaaS products and business-critical internal tools
  • API platforms, microservices, and system integrations
  • Legacy system modernization and incremental rewrites
  • Data-intensive and high-throughput transactional applications
  • Regulated-industry software (healthcare, finance, energy, public sector)
  • High-availability systems with disaster recovery and SLA guarantees
  • Mobile and cross-platform apps backed by robust services

How we deliver

We start with architecture, not code — mapping your systems, compliance obligations, and goals before a line is written. We deliver in scoped milestones with full transparency, quality built in from day one, and we operate what we build long after launch.

1

Discovery & requirements

We map your existing systems, integration points, compliance obligations, and business goals. You get a shared understanding of scope, risks, and success criteria in writing — before anything is built.

2

Architecture & estimation

We design the architecture, choose a fit-for-purpose stack, and produce a transparent estimate broken down by milestone. You get architecture documentation you can take to your own IT and security teams.

3

Iterative delivery with demos

We build in clearly scoped iterations, ending each with working software and a live demo. You see progress continuously, can re-prioritize a shared backlog, and there are no black boxes.

4

QA, security & compliance review

Automated tests, code review, and security scanning run on every change. Before release we run acceptance testing against agreed criteria and produce the compliance documentation your audit needs.

5

Deployment & handover

We deploy to production with you, hand over source code, documentation, runbooks, and credentials, and make sure your team can operate or extend the system independently.

6

Support & long-term evolution

We operate what we build under agreed SLAs, stay accountable for uptime and incidents, and keep the system secure and current as your needs and the regulations change.

Why Softopus

Senior, local team — no offshore handoff

The architects and engineers who scope your project are the ones who build it. No junior bait-and-switch, no time-zone handoffs.

The source code and full rights are yours

You receive the source code, documentation, and an unlimited licence to use, modify, and operate the work. No vendor lock-in, no proprietary traps — you can run or move the system at any time.

We operate what we build

We don't ship and disappear. We stay accountable for uptime, incidents, and the long-term health of the system under clear SLAs.

Security & compliance built in

ISO 27001-aligned delivery, GDPR by design, EU/CZ data residency, and accessibility for the public sector — handled from architecture, not patched at the end.

Transparent estimation and delivery

Milestone-based estimates, a shared backlog you can steer, and working software every iteration. You always know where the project and the budget stand.

Proven at national scale

From government portals serving millions of citizens to business-critical enterprise platforms, we've delivered systems where failure was not an option.

Engagement models

Fixed scope & price

Best for: well-defined projects and public tenders with a fixed specification.

Agreed price for an agreed scope, billed by milestone.

Maximum budget certainty; changes handled through a transparent change process.

Time & materials

Best for: evolving products where scope is discovered as you go.

Billed for actual work delivered, with a shared backlog and regular reporting.

Maximum flexibility; you re-prioritize every iteration and steer the budget.

Dedicated team

Best for: long-running platforms that need a stable, committed team.

Monthly rate for a ring-fenced team of engineers, architects, and DevOps.

A team that works as yours, with Softopus accountable for delivery and quality.

Public-tender & framework delivery

Best for: public-sector buyers procuring under VZ rules or framework agreements.

Structured to fit tender and framework-contract requirements.

We've delivered under public procurement and bring the documentation and process it demands.

Security, compliance & quality

Cybersecurity Act (ZoKB) & NIS2

Delivery aligned with the Czech Cybersecurity Act (ZoKB) and NIS2 — risk management, incident reporting, and resilience for operators of essential and important services.

ISO 27001-aligned delivery

We work to a certified information security management system and apply it across the delivery lifecycle.

GDPR by design & EU/CZ data residency

Data protection is built into the architecture; your data can be hosted within the EU or the Czech Republic and never leaves your control.

Secure SDLC

Automated security scanning, dependency checks, and code review run in every CI/CD pipeline, with penetration testing before release.

Accessibility (WCAG 2.1 / EN 301 549)

Public-sector systems are built to meet the Czech accessibility law and European accessibility standards.

Source code & no lock-in

You receive the source code, documentation, and infrastructure definitions under an unlimited licence; escrow and full handover are available on request.

Documented, auditable quality

Architecture decisions, test coverage, and acceptance criteria are documented as delivery artifacts your audit can rely on.

What you get

  • Full source code in your repository
  • Architecture and technical documentation
  • Automated test suites and CI/CD pipelines

Frequently asked questions

You receive the complete source code, documentation, and infrastructure definitions, together with an unlimited licence to use, modify, and further develop the work — from day one. There's no proprietary lock-in, and we can arrange code escrow on request.

We estimate per milestone after the architecture phase and work against a shared backlog you can see and steer. You get regular reporting, and scope changes go through a transparent change process so there are no surprises.

Wherever your compliance requires. We can host within the EU or the Czech Republic, support on-premises and air-gapped deployments, and design so your data never leaves your control.

Yes. We've delivered under public procurement (VZ) rules and framework contracts, and we bring the documentation, process, and structure that public-sector procurement requires.

You keep everything needed to run it independently — source code, documentation, runbooks, and credentials — plus a structured handover so your team or another vendor can take over cleanly.

Yes. We operate what we build under agreed SLAs, stay accountable for uptime and incidents, and keep the system secure and current as your needs and regulations evolve.
