Who we are
A product company and a custom software team in one.
GSM Media was founded in Skopje in 2010. What started as web development for local companies grew into a complete software company: today we build and operate the systems our clients run their businesses on, from the online shop and the warehouse to invoicing, bank payments and hotel front desks.
We own our platforms. Atom ERP, Atom CMS and our hotel system are developed in-house, which means a new project starts from a proven base instead of a blank page, and every client benefits from improvements made for the others.
We stay small on purpose. You talk directly to the engineers who write your code, decisions are made in days, and the same team that built the system keeps it running for years.
Direct line to the engineers
No account managers in between. The people who build your system answer your calls.
Long-term partnerships
Most of our clients have been with us for more than five years. We grow with them.
Regional know-how
Taxes, e-invoicing, banks, couriers and marketplaces of every country we work in.
