Custom software for every part of your business

Business management systems (ERP, CRM, MES)

One system instead of spreadsheets and scattered tools

We build custom ERP systems that connect inventory, purchasing, sales and finance. The CRM keeps customers, communication and quotes in one place, and the MES shows what is happening on the production floor in real time. Every piece of data is entered once, reports are one click away, and the system follows your processes.

Custom software development

When off-the-shelf software is not enough

If the software on the market does not fit the way your company works, we build custom software that does exactly what you need. We create web applications, internal tools and integrations that connect the programs you already use, so data never has to be entered twice.

AI integration and automation

Artificial intelligence and machine learning built into your own systems

We build AI agents, automations and machine learning (ML) models that work with your company data: they process incoming invoices and documents, answer staff questions based on ERP data, prepare quotes, or forecast from historical data. The solutions connect to your existing systems, and for every project we agree on where and how your data is processed.

IoT and device integration

Shop floor devices and software in one system

We connect your software directly to the devices on your shop floor: control of AGVs (automated guided vehicles), barcode scanning gates, scales, printers, and IoT sensors and devices. Data flows into the system instantly without manual entry, which means fewer errors and faster work.

Mobile app development

Apps for Android and iOS

We develop Android and iOS apps that connect seamlessly to your existing systems. Whether it is an app for your customers or a tool for staff working in the field, we support you from design all the way to publishing in the app stores.

Who we have worked for

How much does custom software cost?

Business reports and charts from an ERP system next to a laptop

Every company is different, so we do not work with template prices. The price depends on the size of the system, how many areas it covers, and which existing programs it needs to connect to. After a free assessment we give you a detailed quote showing exactly what you pay for.

A well-built ERP system can pay for itself quickly. Because the software is built on your real processes, it can cut duplicate work by up to 30% and reduce the time needed to complete tasks by more than 25%.

Frequently asked questions about custom software

Do you only work with companies in Hungary?

No. We work with companies in Hungary and abroad. Most of our projects run online, so we take on work from anywhere in the world, in English or Hungarian.

How much does custom software cost?

The price depends on the size of the system, the number of features and the integrations needed, so we do not work with template prices. After a free assessment we give you a detailed quote showing exactly what you pay for. Development can be split into stages, so you do not have to budget for everything at once.

How long does it take to build an ERP or CRM system?

A small, well-defined system can be ready in a few weeks, while an ERP system covering several areas is usually a project of several months. After the assessment you get a precise schedule, and you can start using finished parts while development continues.

What is the difference between custom and off-the-shelf software?

With off-the-shelf software, the company has to adapt, and often pays for features it never uses. Custom software is built around your processes, does exactly what you need, and grows with your company.

Can you connect a new system to the software we already use?

Yes. One of the biggest advantages of custom development is that it can connect to your existing systems, such as invoicing software, a webshop or accounting, so data does not have to be entered more than once.

How can our company use artificial intelligence?

Mostly where there is a lot of repetitive data work: processing invoices and documents, answering common staff questions from company data, preparing quotes and summaries, or forecasting from historical data with machine learning. In a free assessment we look at where it would bring the most value and connect AI to your existing systems.

Should we replace our existing software?

Not always. It is often cheaper and faster to fix or improve the existing system, while in other cases replacing it pays off in the long run. During a software audit we review the current system and recommend in writing which path makes more sense for your company.

What happens after the software is delivered?

We do not disappear after handover. We help with rollout and staff training, and with our software operations service we take care of updates, backups and troubleshooting, and keep improving the system as needed.
