On-site IT support,
when and where you need it.
Experienced field engineer available across Sofia and the surrounding region. Hardware installs, on-site diagnostics, and vendor coordination - backed by SLA response times, not vague estimates.
Field support services
Hands-on IT work that can't be done remotely - delivered by an experienced engineer who shows up prepared and gets the job done.
On-site troubleshooting & diagnostics
When remote support isn't enough, we come to you. Hardware failures, network outages, intermittent faults - we diagnose and fix on location, minimising downtime for your business.
Hardware install & replacement
Servers, workstations, switches, access points, printers, UPS units - we handle the full lifecycle from unboxing and mounting to configuration and go-live.
Vendor escort & coordination
Need a trusted engineer on-site when your vendor or ISP arrives? We act as your technical representative - ensuring work is done correctly and to your standards.
SLA-backed field support
We agree response times before anything breaks - so when something does, you're not guessing how long help will take.
Guaranteed response times
We work to agreed SLAs - you know exactly when an engineer will be on-site, not just 'sometime today'.
Clear escalation path
If a fix requires parts, a specialist, or vendor involvement, we coordinate the full chain - you get one point of contact.
Post-visit reporting
Every visit is documented - what was found, what was done, and any follow-up actions - so your IT records stay accurate.

Work is agreed in scope before we start. No hidden call-out fees, no per-minute charges for travel within our service area.
