Software development in Miskolc
We build custom software tailored precisely to your processes. Web, mobile, business systems and integrations – from one partner, under one contract.

Software development is the founding competency of Lorz Kft. in Miskolc: for more than 15 years we have been writing code that solves real business problems. We don't sell off-the-shelf packages; we design and build systems shaped around your workflows, using modern technologies. From websites and webshops to mobile apps and business systems, we keep everything in one pair of hands — from development to long-term operation. And because software, IT operations and automation all sit under one roof here, your systems can connect seamlessly to your servers, the cloud and our building automation solutions.

Custom software: what to know before you start
01When is custom software worth it?
You need custom development when the way your business works no longer fits into ready-made tools. It's rarely one big failure that signals this — more often it's lots of small, daily workarounds that together cost working hours and cause errors.
If several of the following sound familiar, it's worth seriously considering a system of your own. If an existing product covers your needs well, however, we'll recommend that instead — and we'll tell you so honestly during discovery.
- the same data has to be entered by hand in several places (spreadsheet, email, invoicing software);
- spreadsheet versions contradict each other, and nobody knows which one is current;
- an important process lives in one employee's head and grinds to a halt when they're away;
- more and more manual add-ons and “clever” workarounds pile up around your off-the-shelf software;
- pulling together data for reports takes hours, so decisions end up being based on gut feeling.
02Custom, off-the-shelf — or a smart mix of both?
Off-the-shelf software gets you started quickly and runs for a predictable subscription, but in return your business has to adapt to it. A custom system adapts to your existing processes and strengthens your competitive edge, but it needs more planning up front.
In practice the best solution is often a mix of the two: proven ready-made systems (invoicing, accounting, webshop engine, Microsoft 365) stay in place, and a thin custom layer connects them and does what none of them can. That's system integration — and it's often the development with the fastest payback. If the question is about your website, take a look at our website development service.
03How does a vague idea become a precise, fixed-price quote?
Most software projects don't fail on the programming — they fail because the two sides understand the same sentence differently. That's why every engagement starts with discovery: we walk through your processes with the people who carry them out every day.
At the end of discovery you receive, in writing, a prioritised feature list, sketches of the key screens, a timeline and an itemised, fixed-price quote. For larger systems we start with a well-defined first version (MVP) that can be in use within weeks — and we re-prioritise further features based on real-world usage.
04Which technologies do we use — and why?
We build on proven, widely used technologies so that your system stays maintainable for years to come and isn't tied to a single developer. Our typical choices are React and Next.js for web interfaces, .NET and Node.js on the server side, PostgreSQL for databases, React Native for mobile, and Microsoft Azure and Docker for hosting and operations.
We always choose the technology to suit the task, not the other way round: if an existing system runs on a different platform, we adapt to it. We record the reasoning behind our choices in the discovery documents, so the decisions remain traceable later on.
05Who owns the source code, and what happens after handover?
With custom software, the three most important questions are: who has access to the source code, what rights you have to use the system, and who can continue developing it if the original developer drops out for any reason. We set these out in writing, in advance, in the quote and the contract — they're never left to be discovered at handover.
Handover comes with documentation and training. After that, we can run and further develop the system for you as needed — with servers, cloud and user support covered by our managed IT service, under the same contract.
06Why does it matter that the development team is in Miskolc?
Designing a business system takes a lot of thinking together. We hold process discovery and key workshops in person, at your premises — in Miskolc and the surrounding Borsod-Abaúj-Zemplén county this isn't a separate travel project, just part of the way we normally work.
During development you talk to the same developers who work on your system, and after go-live a local partner is responsible for keeping it running. If the software also needs to connect to your machines, your network or your building automation, we handle that from a single source too.
How we work
- 1
Discovery & planning
We get to grips with your business goals and existing processes, then produce a precise technical plan and timeline. The quote is transparent and fixed in advance.
- 2
Architecture & prototype
We build the right architecture and show you the direction with an early prototype. You see what you'll get before development even begins.
- 3
Iterative development
We deliver working features in short, regular cycles. You follow progress throughout, and we can refine the direction as we go.
- 4
Testing & go-live
We test the system thoroughly, then deploy it safely to the cloud. Handover comes with full documentation and training.
- 5
Operation & support
We don't leave you on your own after launch: we maintain, update and keep developing your system for the long term. One partner, one contract, one invoice.
What determines the cost of custom software?
The cost of custom software isn't driven by the number of screens, but by how many business rules, how much data and how many external connections it has to handle reliably. These are the factors that move the effort the most:
- 01
Processes and business rules
How many steps a process has, how many exceptions and approval rounds it involves, and which permission levels need to be handled.
- 02
Integrations
Invoicing software (e.g. the Hungarian services Számlázz.hu or Billingo), NAV Online Számla (Hungary's real-time invoice reporting), accounting, webshop, bank or courier services — every connection is a separate piece of development and testing.
- 03
Data migration
Cleaning, standardising and safely transferring data from old spreadsheets or a previous system.
- 04
Interfaces and platforms
Whether a browser-based interface is enough or you also need a mobile app — perhaps with offline operation for colleagues working in the field.
- 05
Security and compliance
GDPR, logging, access control, backup and recovery requirements — these form the backbone of the system.
- 06
Operation and further development
The hosting environment, monitoring, updates and the level of support you need shape the cost across the system's entire life cycle.
We give a fixed price after the discovery phase, in writing and itemised — we walk through the factors above together in the first, free consultation.
