Gábor Lőkös · Rendszermentor

I build a system into your business. One that runs without you.

I have helped more than 130 Hungarian companies go digital. I see where money, time and information leak away, and I know how to stop it. I don’t sell software: I build processes around the way you actually work, and I stay with you until your team truly uses them.

ERP and operations E-commerce Process design AI automation
0companies trained or consulted, invoices to prove it
0companies where I work hands-on every day
0SKUs in the catalogue I operate
0goal: a system that works for you
Sound familiar?

If any of these ring a bell, you are in the right place.

I didn’t get to know SMEs as a consultant but on the support line and in sales: I am the one who picks up the phone when invoicing breaks, the warehouse stalls, or nobody can find yesterday’s quote. Across hundreds of companies the same patterns keep coming back, and every one of them has a working fix.

Everything lives in your head

If you are out for a week, the company stops. The knowledge lives in you, not in a system. That is not a badge of honour, it is the biggest brake on growth.

You enter the same data three times

Paper, Excel, email, notebooks. Data scatters, retyping breeds errors, and errors cost money and customer trust.

Constant firefighting

The team spends the day putting out fires, so there is never time to improve. Yet it is exactly the missing system that keeps starting the fires.

You bought software, nobody uses it

You have bought an expensive system before that now gathers dust, because the team slipped back to notebooks and Excel. The real fear isn’t the software, but that your staff will sabotage the new one. Without rollout, training and mentoring, even the best system is just another monthly fee.

I don’t guess and I don’t preach theory: I have worked on the rollout of more than 130 companies, so I know exactly where things get stuck, and what makes them stick.

The Rendszermentor method

Three steps from chaos to a working system

I don’t start with the software, I start with your processes. The tool (ERP, e-commerce, automation, AI) always adapts to your goals, never the other way around.

01

Assessment

We walk through your processes from quotation to invoicing. I show you where money, time and information slip away. You get a written action plan that stays yours even if we stop here.

02

System building

We roll out the tools that fit your goals: operations, inventory, e-commerce, invoicing, AI automation. We use what is good for you, not what someone wants to sell you.

03

Mentoring

I don’t just set up the software: I break the staff’s resistance and make sure your team actually uses it. I train the people, we measure the results and keep fine-tuning until the system becomes a natural part of everyday work. I won’t leave you alone with the software.

Day to day I run a database of 19 million SKUs. If I can handle that, your few thousand products or warehouse won’t even make a dent. Running a shop with a huge product list? Check out the Product Search module: proven on car parts, pluggable into any webshop engine.

About

Who is behind Rendszermentor?

I am Gábor Lőkös. Every day I take part in running five companies, from very different vantage points. At an ERP software company I stand between the customers and development: I understand what a business needs, guide it through the rollout, test the system, and translate real needs for the developers. I manage the full digital operation of an auto-parts business with a catalogue of more than 19.3 million part numbers. I handle finance at an industrial refrigeration company, I built and operate a webshop for a confectionery, and meanwhile I am building my own venture, Rendszermentor.

I learned the demand for quality in the best possible place: I worked in quality management at the Mercedes-Benz factory in Kecskemét. In a multinational environment I picked up systems-level thinking and the disciplined, recurrence-proof way of solving problems (8D). Ever since, I look at every system the same way: it is not enough for it to work, it has to be measurably good.

I earned my software engineering degree at the University of Szeged, with a minor in teaching: that is where I learned both how to build systems and how to explain them clearly. Practice comes from the everyday: I have trained or consulted 131 companies on business operations so far.

I have seen from the inside what makes a rollout fail, and what turns software into a true everyday working tool. I created Rendszermentor out of a conviction: small and medium businesses don’t need yet another piece of software. They need someone who speaks the language of their processes and sees the change through.

  • 131 companies trained, consulted or onboarded, documented by invoices
  • ERP, e-commerce, automation and AI in practice, not in theory
  • Quality-management and multinational background (Mercedes-Benz plant, 8D methodology)
  • Experience across trade, manufacturing, services and hospitality
Testimonials

What my clients say

We had been putting off the ERP switch for months, terrified that the warehouse and invoicing would stop during the process. Gábor came in as an external mentor: he brilliantly managed the software vendor, translated our needs to the developers, and ran the data migration with 100% accuracy. Our business didn’t stop for a single day, the changeover happened unnoticed. Had I known this kind of vendor-independent help existed, I would have done it two years ago.

Gergely KántorManaging Director, Finucci Technology Kft. (Retail)

We already had an expensive ERP system, but it gathered dust on the shelf because the staff sabotaged it and stuck to their old notebooks and Excel sheets. What’s brilliant about Gábor is that he didn’t just set up the processes, he held our team’s hand until the system became a natural part of everyday life. He broke the internal resistance. Finally I don’t have to micromanage the company, the software enforces order.

János PászorManaging Director, Gold Company Kft.

I used to work 10-12 hours a day, and the phone kept ringing even on holiday, because every process lived in my head. During the assessment, Gábor and I saw exactly where my colleagues’ time was leaking away. We introduced online worksheets, and thanks to his experience with a 19-million-SKU database he sorted out our huge warehouse in no time. Today I see clean dashboards, and my company generates profit on its own, without me. I have more free time.
