A locally owned IT company for Jacksonville businesses
You'll know our names. We'll know your network.
Advanced IT Support has looked after small and midsize businesses in Jacksonville since 2014. We work three ways: managed IT for one monthly fee, co-managed alongside your own IT staff, or by the hour when you only need us now and then. Whichever it is, our office is on Salisbury Road in Southpoint, and when you call, a person answers who already knows your setup.
“Super friendly local staff. Very knowledgeable. They help our company with all of our IT needs and are very fast responding to any request. They provide both on site and remote assistance. Highly recommend their services.”

Most businesses call us for one of three reasons
You have been holding it together yourself
Someone has been doing the IT alongside their real job: the office manager, the owner, or the one person who happens to be good with computers. It worked fine at eight people. At twenty-five, it is a second full-time job nobody has time for, and critical maintenance starts slipping. That is usually when companies hand it to us on a managed IT agreement, or open the pricing calculator to see what handing it off would cost.
You have a provider and it has stopped working
Maybe the local firm you signed with got acquired, and the engineer who actually knew your network left eight months ago. Maybe tickets bounce between tiers and nothing gets owned. Either way, you are explaining your setup from scratch every time, and the scanner still doesn’t scan. With managed IT, one local team owns your whole environment, and we handle the handoff from your old provider so you don’t have to.
Something broke and it was expensive
Three days of network downtime. Ransomware locking critical files. An executive email account compromised with wire instructions quietly routed to the wrong bank. Most companies call us right after the first one, and our cybersecurity services and disaster recovery work is about making sure there isn’t a second.
“It doesn’t keep me awake at night. I know they’re there to protect our systems.”

Where would you like us to start?
IT support
How support works day to day: who answers, how fast, and an hourly option when you only need us occasionally.
IT consulting
What to replace, when, and what it will cost. Migrations, projects, and the budget conversation before the budget year.
Cybersecurity
Risk assessment, endpoint protection, email security, and the training that stops most of it at the door.
Managed IT
One monthly agreement for your help desk, monitoring, patching, security and Microsoft 365. Month to month.
Cloud and Microsoft 365
Migrations, tenant setup, licensing that matches what you actually use, and support afterward.
Co-managed IT
You have someone internal. We cover the gaps, the after hours, and the projects they do not have time for.

What other clients say
“I highly recommend the team at Advanced IT Support. I’ve been using Jeremiah Dillingham and team for years and they are super dependable and knowledgeable. The team is always responsive and they provide fast dependable service. They recently helped me with a business location move and were top notch throughout the strategy planning and new site planning to the actual day of installation, moving of all computers, printers, phones, modems, and coordination with Comcast Business. I wouldn’t trust anyone else with my IT needs. These guys are great at their job!“
Jim S.
Transportation Company | Jacksonville, FL
“Incredible service, locally owned and detail oriented, very knowledgeable! These guys are really wonderful and help my small business so much! We left a much larger and impersonal corporate company to come to Jeremiah and his team, and we are so happy we did. Cannot recommend them enough, always happy to help, very responsive and quick.”

Who we are a good fit for
We work best with businesses running roughly 5 to 100 users. Windows, Mac, or a mix of both. Microsoft 365 or Google Workspace.
We support accounting and CPA firms, medical and dental practices, veterinary clinics, law firms, logistics and transportation companies, property managers, and nonprofits across Northeast Florida. If you are in a regulated industry, we run the risk reviews, written policies and staff training as an ongoing compliance service rather than a one time project.
If you are a one-person shop or a 400-seat company, we will point you to a partner we work with closely.
What this usually costs
Fair question, and there is a calculator on the site that answers it rather than a form that makes you ask.
Managed IT is priced per user, per month, and the rate per user comes down as you add people. Servers, the Advanced Security level, and the number of locations each move the total, and there is a nonprofit rate. Co-managed is priced differently again, because you are bringing part of the work yourself.
The managed IT page shows exactly what each level includes.
Project work is billed hourly, at a lower rate for managed clients than for everyone else. Onboarding is a separate one time project fee, quoted once we have seen what we are taking on.
If a monthly plan is not right for you yet, we still do break and fix work, and we will say so if that is the better fit.
Where we go
Our office is at 4237 Salisbury Road, Suite 208, in Southpoint. From there, we provide responsive on-site and remote IT support across Jacksonville and Duval County, including Baymeadows, Deerwood, the J.T. Butler Boulevard corridor, Riverside, Mandarin, and the Beaches.
We also support businesses throughout St. Augustine, Clay County (including Orange Park and Fleming Island), and across the Georgia line in Brunswick and Waycross.
Most day-to-day tickets are resolved remotely because it gets your team back to work faster. When an issue requires hands on hardware, we drive straight to your door.
Tired of IT problems slowing your business down?
Talk to Jeremiah.
No sales pitch. Thirty minutes to understand your situation and work out whether we are the right fit. If we are not, I will tell you that too.
