When we reached out to Simplex Systems, we needed a complete optimization and modernization of our IT infrastructure. Our systems had been built up over time without a clearly structured security layer, and our process organization no longer met the needs of a fast-growing company. The Simplex team approached the project with exceptional professionalism — they conducted a thorough analysis, proposed specific improvement steps, and took on the implementation with full commitment. They built a stable, secure, and well-structured IT environment that not only resolved the accumulated issues but also laid the foundation for future growth. Since then, we've been using their subscription-based support — they're lightning-fast, proactive, and think strategically. Working with them gives us peace of mind and confidence that our IT operations are in safe hands. Simplex Systems has become a trusted partner we can fully rely on.

Anna Anchova – IT Director, Scania Bulgaria

We've been working with Simplex for so long that we're certain — if our systems ever crash, it must mean they've been hijacked by an alien Terminator sent by Skynet. Our apparent calm can't hide the fact that we're practically dependent on their support, which saves us from our own ambitions to blow everything up.

Filip Mutafis – CEO, Paysera Bulgaria

We’ve been working together for over a decade. They take care of everything on the IT side, and over time, you simply get used to being able to rely on them. Technology evolves, and so do we — with their help, we stay up to date. Over the years, we’ve replaced servers and systems, upgraded hardware and software, migrated services — and all of it happened without us ever feeling disruption. They provide us with reliable data protection and software stability. Peace of mind and security — that’s what we get from them.

Vassil Jivkov, Owner, Prodes

Simplex Systems has been handling all of our IT needs for so long that, to us, they’ve simply become part of how we operate. In the legal field, reliability, confidentiality, and information security are not advantages — they’re requirements. Simplex Systems meets those requirements without compromise. They understand the nature of our work and consistently provide the stability and security that allow us to focus on what truly matters.

Georgе Sabev – Managing Partner, Sabev & Partners Law Firm

We’ve been working with Simplex Systems for … years. We’ve always received impeccable service, attention to our digital processes, and prompt, timely responses whenever needed. System maintenance and license renewals are always handled on time and with minimal disruption to our work. Thank you for the work you’ve done and for being a partner we can rely on.

Ivan Ivanov – Managing Director, Agrotime

We’ve been working with the team at Simplex Systems for over 15 years — even before the company itself was officially founded. Over that time, we've gone through various stages and changes, but one thing has remained constant: the confidence that we can always rely on them. They know how to keep our work environment stable — without unnecessary noise or disruptions. They’re the kind of team you don’t see, but you can feel through the results.
