A small business IT checklist gives owners in Miami and Naples a practical way to find gaps before they become outages, security incidents or rushed purchases. You do not need to be an IT engineer to review the basics. Start with your devices, accounts, backups, network, phones and vendors, then assign someone to fix anything that does not have a clear owner.
1. Build a Current Device Inventory
List every business-owned or business-managed device:
- Desktop computers
- Laptops
- Servers
- Firewalls
- Switches
- Wi-Fi access points
- Printers
- VoIP phones
- Tablets
- Mobile devices
- Backup appliances
Record the user, location, operating system and warranty or replacement information where useful.
An inventory helps answer a simple question: what are we responsible for protecting and supporting?
2. Check Operating-System Support
Unsupported operating systems create avoidable risk.
Microsoft says standard Windows 10 support ended on October 14, 2025. See Microsoft's Windows 10 end-of-support guidance.
Review each workstation and identify anything running an unsupported operating system or application.
If a specialized business application requires an older system, document the dependency and create a replacement plan.
3. Confirm Patch Management
Ask:
- Who installs operating-system updates?
- Who checks failed updates?
- Are browsers updated?
- Are firewalls and switches updated?
- Are remote-access tools patched?
- Are business applications current?
CISA's small and medium business resources list software updates as a core cybersecurity practice.
Patching should be a managed process, not something that depends on an employee clicking “later” indefinitely.
4. Require MFA
Review every important cloud service.
Prioritize MFA for:
- Microsoft 365
- Google Workspace
- Accounting
- Cloud storage
- Remote access
- VPN
- Backup portals
- Administrative accounts
CISA recommends requiring MFA wherever possible and starting with sensitive and privileged access.
Document exceptions instead of allowing them silently.
5. Review Administrator Access
Find out who has administrative rights on:
- Computers
- Microsoft 365
- Firewalls
- Servers
- Backup systems
- Websites and domains
- Business applications
Remove access that is no longer required.
Employees should not use broad administrative privileges for ordinary daily work unless there is a specific reason.
6. Verify Backups
Do not stop at “the backup says successful.”
Confirm:
- What is backed up
- How often
- Where copies are stored
- Whether a protected offsite or isolated copy exists
- Who receives failure alerts
- When a restore was last tested
Ready.gov says IT disaster recovery should be developed alongside business continuity planning. Its business emergency plan guidance specifically includes communications, IT recovery and continuity.
A restore test is what turns a backup from a hope into a recovery tool.
7. Review Endpoint Security
Check that company computers have:
- Active endpoint protection
- Current definitions or signatures where applicable
- Disk encryption where appropriate
- Screen-lock policies
- Monitoring
- Unsupported software removed
FLTECHS lists 24/7 endpoint monitoring as part of its managed IT service.
Ask what happens when an endpoint stops checking in or security software is disabled.
8. Review Email Security
Check:
- MFA
- Spam filtering
- Anti-phishing protection
- Suspicious forwarding rules
- External forwarding
- Shared mailbox permissions
- Former employee access
- Domain settings such as SPF, DKIM and DMARC
Email is a major entry point for account compromise, so it should be reviewed regularly.
9. Check Employee Onboarding
A new employee should not receive random permissions based on whoever trained them.
Document:
- Account creation
- MFA
- Device setup
- Required applications
- File access
- Business phone access
- Security training
- Password-manager access
Use role-based access where practical.
10. Check Employee Offboarding
When an employee leaves:
- Disable sign-in
- Revoke active sessions
- Recover devices
- Remove business phone access
- Transfer file ownership
- Remove VPN
- Review shared passwords
- Remove SaaS access
- Forward or archive email where appropriate
Do this promptly.
11. Review the Network
Check:
- Firewall support status
- Switch age and firmware
- Wi-Fi coverage
- Guest Wi-Fi separation
- Cabling
- Internet reliability
- Backup internet
- UPS battery status
A cloud-first business still depends on the local network to reach those cloud services.
12. Review Business Phones
Document:
- Main numbers
- Direct numbers
- Call queues
- Auto attendants
- Business hours
- After-hours routing
- 911 locations
- Mobile users
- SMS-enabled numbers
FLTECHS uses FlowPBX for business phone systems, routing, SMS/MMS and integrations.

13. Check Domain and Website Ownership
Make sure the business knows who controls:
- Domain registrar
- DNS
- Website platform
- Hosting
- Google Business Profile
- Analytics
- Search Console
Do not let a former employee or old vendor become the only person with access.
14. Review Vendor Access
List every outside company that can remotely access systems.
For each vendor, record:
- Contact
- Systems accessed
- Account used
- MFA status
- Business purpose
- Expiration or review date
Remove old remote tools and stale vendor accounts.
15. Write Down the Recovery Plan
If the office loses power, internet or access to the building, employees should know what happens next.
Document:
- Emergency contacts
- Phone rerouting
- Remote-work access
- Backup internet
- System shutdown
- Data recovery
- Customer communication
For Florida businesses, continuity planning should include storm season even if the business has never experienced a major outage.
How Often Should You Use This Checklist?
Review the full checklist at least when:
- You change IT providers
- You open a new location
- You hire rapidly
- You adopt a major new application
- You experience a security incident
- You prepare for hurricane season
- You plan the annual technology budget
Smaller items such as patches, backups and security alerts should be managed much more frequently.
FLTECHS says it has served Florida businesses for more than 20 years, with coverage across Miami, Naples and Fort Myers. Its site lists an 8m 41s average response time, 99.98% uptime across systems and 24/7 endpoint monitoring.
Frequently Asked Questions
What is the most important item on a small-business IT checklist?
There is no single item. Identity, patching, backups, endpoint security and network reliability work together.
How often should backups be tested?
The schedule should match how critical the data is and how much loss the business can tolerate. The important point is to have a documented restore-testing process.
Should small businesses document all IT passwords?
Critical access should be documented securely in a controlled password-management process, not in an unprotected spreadsheet or notebook.
Can an MSP complete this checklist for us?
Yes. A managed IT provider can inventory systems, identify gaps and help assign ongoing ownership.
FLTECHS provides managed IT services for Florida businesses that want monitoring, cybersecurity, cloud support and a documented technology plan.
