What we cover

Eight disciplines, one helpdesk number.

Your team calls, emails, or opens a ticket. We classify it at intake, dispatch the right engineer, and close it inside the SLA. No menu mazes, no callback-tomorrow.

Remote support

Phone, ticket, or chat. Most incidents resolved without a site visit. Screen-share for software, configuration, and account issues.

On-site support

Engineer dispatched to your office for hardware swaps, network rebuilds, install jobs, or anything that needs hands-on. 4-hour on-site response in NYC, LA, SF, Houston, Dallas, Austin, and Chicago metros; next business day nationwide.

Emergency response

P1 incidents (server down, ransomware, site-wide outage) escalate immediately. Engineer on the case in 5 minutes, 24/7, holidays included.

Hardware support

Desktops, laptops, printers, peripherals. Diagnostics, repairs, replacements. Brand-agnostic. Spares stocked for the most common configurations.

Network & WiFi

Routers, switches, access points, firewalls. Configuration, troubleshooting, capacity planning. ISP coordination so you don't run a vendor war room.

Cloud & Microsoft 365

Tenant operations, user lifecycle, security baselines. We support whatever's already deployed: M365, Google Workspace, Azure, AWS basics.

Security incidents

Phishing, malware, account takeovers. Containment, recovery, and a written incident report. Coordination with your insurance carrier when relevant.

Vendor coordination

ISP, telephony, equipment OEMs, software vendors. We deal with their support so your team doesn't lose a day on hold.

Three modes of support

On-site, remote, or emergency, pick how you need us today.

Most tickets resolve via remote session. Some need an engineer in the office within the hour. A few are P1 emergencies that need everything we have. Each lane has its own response profile.

Engineer in your office, hands on the gear.

Why GR IT

Six reasons clients pick us over the alternative.

Concrete operational facts, the kind that show up when you ask for references.

US-based engineers

30+ engineers across our US delivery teams. 4-hour on-site response in Tier-A metros, next business day nationwide. We never subcontract on-site work to someone you didn't hire.

Brand-agnostic

SLAs measured, not promised

If we cannot resolve your issue, you do not pay. Simple. We carry the risk on every ticket so you do not have to gamble on the engineer who picks up.

Fixed-price guarantee

How it works

From first ticket to closed in four steps.

Every incident follows the same path so nothing gets lost between handoffs.
  1. 1

    Intake

    Within SLA

    Phone, email, ticket, or chat. We classify priority, capture the affected system, and assign the right engineer. You get a ticket number immediately.

  2. 2

    Diagnostic

    15-60 min

    Engineer opens a session (remote) or rolls to your office (on-site). Root cause documented in the ticket as we work, not after.

  3. 3

    Resolution

    Per SLA

    Fix applied, tested, and confirmed with the affected user. Workarounds logged for any deferred work. Hardware swaps logged in your asset register.

  4. 4

    Documentation

    Same day

    Ticket closed with root cause, fix, and prevention notes. Recurring issues flagged for the next quarterly review so we stop them at the source.

We moved from one stressed in-house IT person to GR IT Support and our ticket close time went from "next week" to "same morning". The cost is half what we used to budget and we finally stopped losing Fridays to network issues.
