The Most Common IT Mistakes Small Businesses Make
After years of supporting small businesses, these are the IT mistakes we see over and over. Avoiding them saves money, time, and serious headaches.
Small businesses make the same IT mistakes repeatedly — and each one has a predictable cost. Here are the most common mistakes we encounter, and what to do instead.
1. Using Consumer Hardware for Business
Consumer computers (Best Buy laptops, home routers) aren't built for the duty cycle, reliability requirements, or management needs of business environments. Business-line hardware costs 20–30% more upfront but lasts longer, has better warranties, and has longer software support lifecycles.
2. No Real Backup (or Untested Backup)
Many businesses have 'backup' that hasn't been verified in months or years. A backup that hasn't been tested isn't a backup — it's a false sense of security. Test your restore process quarterly.
3. Skipping Multi-Factor Authentication
MFA is free in Microsoft 365 and Google Workspace and takes 30 minutes to enable for your entire organization. Without it, a single compromised password gives attackers full access to your email, files, and business applications.
4. Keeping Computers Too Long
A 6-year-old computer that takes 5 extra minutes per day is costing you real money in staff time. At $25/hour, that's $100+/month per slow computer. A new computer pays for itself in under a year through recovered productivity.
5. No Written IT Documentation
When the person who 'knows all the passwords' leaves, businesses without IT documentation are in serious trouble. Document your network, accounts, licenses, and vendor contacts. Store documentation securely and make sure more than one person has access to it.
