Billing Specialist

Black Bull Group was founded in 2009 with a clear mission: to become a reliable, agile, and effective partner for armed forces, governments, and international organizations.

We specialize in integrated military logistics and also operate a robust security and intelligence division that works independently, providing strategic support to governments as well as publicly traded multinational corporations. These two core areas define who we are: an operational company with a global outlook, on-the-ground experience, and the ability to respond quickly in the most demanding environments.

On the logistics side, we provide services to naval, ground, and air forces in over 800 locations across five continents. Our core business includes military vessel husbandry services, as well as support for aerial and land deployments. This extends to the supply of fuel, food, spare parts and equipment, construction and maintenance of military facilities, waste management, emergency mission support, and last-mile logistics in remote or high-risk areas.

We operate 24/7, 365 days a year, with global coverage through our own network and a flexible structure that adapts to the needs of each mission.

We currently work with more than 30 Ministries of Defense, are a NATO contractor, and collaborate with several United Nations agencies. Our experience, proven in high-pressure environments, has made us a trusted reference in the sector—known for the quality of our services and our ability to anticipate and respond to operational needs.

Since joining the ES-KO Group, we have expanded our strategic capabilities and strengthened our reach in international operations. This alliance has allowed us to create powerful synergies in areas such as large-scale deployment logistics, critical infrastructure construction and management, field catering services, and humanitarian mission support.

Our Security and Intelligence Division operates as a strategic advisor on critical infrastructure protection, risk management, threat prevention, and cybersecurity. Our team of experts supports both public institutions and global corporations, providing analysis, protocols, and operational solutions in complex and sensitive environments.

All of this rests on a solid organizational structure, a highly qualified team, and an unwavering commitment to excellence. We operate under the highest international standards.

Black Bull Group is not a conventional company. We're not here to do the bare minimum—we're here to raise the bar. If you're part of this team, you can be sure your work makes an impact and leaves a mark.
