INVITATION FOR PARTNERSHIP
In light of the growing instability of global supply chains and the increasing demand for reliable, localized, and technologically advanced solutions, 4S4 Group views strategic production alliances as a key instrument for sustainable growth and expanded presence across critical markets.
About Us: From Industry Leader to Technological Platform
Established in 2006 in Bulgaria, 4S4 Group successfully developed and exported cash registers and tachographs to over 14 countries worldwide (Bulgaria, Greece, Romania, Serbia, Croatia, Slovenia, Czech Republic, Hungary, Kenya,
Tanzania, Rwanda, Niger, Benin, Nigeria). This phase shaped a strong engineering foundation and an extensive international business network.
In 2022, in response to the shifting global landscape, we made a strategic decision to transform our existing infrastructure into a versatile, full-cycle electronics manufacturing plant, designed to serve both our own product lines and the needs of external clients.
Our transformation has delivered:
• 15,000 m² of production space in Botevgrad — a modern, high-automation facility for everything from
prototyping to mass production
• 11 SMT lines with a total capacity of 1,585,400 CPH, equipped with Juki, Samsung, Yamaha systems
• In-house mechanical workshop, laser cutting, automated painting, assembly, packaging
