User and device support with a defined request process
Managed IT for Cook, DuPage, Grundy, Kane, Kendall & LaSalle Counties
Managed IT Services for Illinois Businesses
Managed IT is an ongoing arrangement for the technology your business needs to operate: user support, device maintenance, account administration, networks, backup, and planning. The agreement identifies which work the provider owns and how the business gets help.

Stadtler Technologies is based in Yorkville and serves Cook, DuPage, Grundy, Kane, Kendall, and LaSalle Counties. Jim Stadtler’s managed IT experience dates to 1998; the company was founded in 2013.
What belongs in a managed IT agreement
Start with an inventory of users, locations, devices, applications, and vendors. A monthly fee is difficult to compare when one proposal includes servers and cloud administration while another covers only staff computers.
Identify recurring tasks, support hours, urgent escalation, approval for disruptive work, and exclusions. Equipment, onboarding, migrations, incident recovery, and other projects may need separate pricing.
Scheduled maintenance and review of failed updates
Account, network, and Microsoft 365 responsibilities
Backup review, recovery requirements, and appropriate tests
Documentation, vendor coordination, and a prioritized work list
Connect routine maintenance with staff support
A service should track both the visible ticket and the work that prevents repeated trouble. A failed update, a device that stopped reporting, and a recurring login problem need an owner and a next action.
Ask what a completed task establishes. Closing an alert is not always the same as resolving the cause. Our proactive maintenance page explains the recurring review and exception process.
Put security and recovery in the same operating plan
Review account access, device protection, patching, remote connections, backup, and who responds to alerts. A license list should not substitute for evidence that the expected systems are covered.
Use a co-managed arrangement when your team keeps part of IT
An internal IT lead may retain application ownership or strategy while an outside provider handles agreed support, maintenance, or projects. Write down the split at the task level, including escalation and change approval.
See co-managed IT services for a responsibility matrix. If the immediate need is a specific decision or project design, IT consulting may be the better starting point.

Make the transition reviewable
Inventory accounts and systems, verify business ownership of administrative access, collect documentation through a secure process, and record unresolved issues. Agree how existing providers and vendors will be involved.
Ask for a report that shows the open work
A useful report lists the systems covered, unresolved issues, the next action, its owner, and any decision or budget required. Include approved exceptions and failed maintenance rather than reporting only ticket totals.
For example, a laptop waiting for a restart, an unsuccessful backup, and an application approaching end of support are different decisions. Their status should help the business decide what happens next.
Bring your operating needs to the first conversation
Bring a current system and provider list, one recurring problem, an approaching business change, and any support proposal you are comparing. Missing documentation is itself a useful finding.
