Why your IT person leaving should not panic your business
When your one IT person tells you they're moving on, the panic is real. Who knows where everything is? Who has the passwords? What if something breaks the day after they leave?
That panic is legitimate, but the outcome it predicts isn't inevitable. Plenty of businesses have made this transition smoothly. The difference is preparation, and it's easier than you think.
Document everything while they're still there
This is the single most important step, and it has to happen before they leave. You need a written record of what's running, how it's configured, where the backups are, and what the passwords are. Not in someone's head or an email from 2019. Written down, accessible to you, and stored securely.
Have your IT person create a simple inventory: server names and what they do, cloud services you use, where licenses are purchased, what monitoring is in place. Include passwords (encrypted and stored securely, or moved to a password manager your team can access). Document the backup system, how often it runs, and when the last successful restore was tested.
This takes a few hours at most. Not doing it is the mistake that turns a departure into a disaster.
Test your backups before they leave
An untested backup is a guess. If your IT person has never actually recovered a file or a server from backup, you don't know whether the backups are working. Have them do a full restore test before they go. Document the results. If something fails, fix it now, not on an emergency call six months from now.
This is standard practice with a proper managed IT partner, and it's a habit worth keeping in-house too. After they leave, you need monthly proof that your backups actually work.
Know who to call when they're gone
Decide now whether you're hiring someone internally to replace them, bringing in a contractor for critical support, or switching to a managed IT partner. Don't wait until your former IT person is already on their way out the door and you're scrambling.
If you hire another full-time person, your documented system and tested backups make their first month far less chaotic. They have a roadmap instead of having to reverse-engineer everything.
If you go with a managed partner instead, the first month is usually an onboarding process where they document your environment (filling in any gaps in what you've already written down), verify your backups are actually working, and set up monitoring so problems don't blindside you. A good managed IT provider treats this handoff from an internal person as routine.
Don't let this happen again
Once you've made it through a departure, the lesson is clear: having all your IT knowledge in one person's head is a business risk, not a cost-savings measure. Whether you replace your departing IT person or switch to managed support, build in redundancy from day one.
That means documented systems, tested backups, and either multiple people who understand your setup or a partner who's monitoring it constantly. It costs less than an emergency data recovery, and it prevents the panic when someone eventually leaves.
