Committed to the #1 Customer Experience in Managed IT and Telecommunication Services

Since opening our doors in 1993, Access One has remained focused on one primary goal: to build the number one customer experience in business technology, managed IT, and telecommunications services. We work with small and medium sized businesses to create custom solutions – no upsells, no fluff -- just what you need to excel in your field.

Our customer service has been recognized by the prestigious Stevie Awards for four years straight. We’re proud to know that our hard work makes a difference to the community and helps local Chicago-based businesses grow and compete in our hometown as well as on the national stage.

Personalized IT and Telecommunications Services

We specialize in meeting the unique needs of growing businesses. That’s why we create your custom package just for you with no needless add-ons or upsells. And with our scalable, high-speed, high-capacity infrastructure, your growing pains will be less painful when your business starts to scale up.

Our packages contain everything from Plain Old Telephone Service (POTS) to state of the art Hosted PBX offering integrated voice, video, and messaging solutions, so no matter if your business is run out of your garage, in the office, or on the road, we can find a package with exactly what you need.

All-in-One Business Services

Managing your data, IT, cloud, phone, and call center services can be a nightmare when they’re each spread across different companies, especially if they’re spread all across the state or country. We consolidate all of your services in one local, easy to manage location. Better yet, by bringing all of your services together under one roof, we’re able to cut costs and pass the savings directly to you.

Always Up to Date

The world of telecommunications and IT changes all the time, and it’s easy to fall behind on the latest technology. Our experts stay on the cutting edge of every change in communication technology to keep your systems running smoothly and secure from threats. The peace of mind that comes with a secure infrastructure system is priceless, not only for you, but also for your customers who can rest easy knowing that their personal and financial information is safe.

Because we work with so many clients in a wide range of industries, we’re always alert about the next big threat. Once anything new hits our radar, you can be sure that we’re already working on securing your systems to stop it in its tracks.

Seamless Integration

Upgrading or updating your systems is always a delicate process. One minor hiccup can cause data duplication, loss, or corruption and set your business back for days while you recover - or worse. We test every new update and integration into your system so we can anticipate problems before they arise. We’ll also backup all of your data regularly in case of a disaster.

    - David SteinMalcolm S. Gerald and Associates
  • "As customers since 2000, last year Access One Inc saved us an additional $9,300 per year by transitioning several of our services to the underlying providers who offered the lowest MRC.  The service migrations were smooth and went virtually unnoticed by our users.  AT&T’s rates as a new customer didn’t come close to those that Access Once was able to offer us as existing customers.  Thank you for the savings!"
