Here’s something the IT industry won’t tell you: most small businesses don’t need an IT department. They need a sensible setup, a few good habits, and the confidence to handle the basics themselves. I say that as someone who supports small business technology for a living – the businesses that run smoothly without dedicated IT staff aren’t lucky, they’re just set up properly.

This is the practical, plain-English guide to doing exactly that: running your business technology yourself, safely, without hiring an IT person you can’t yet justify. No jargon, no fear-selling – just what actually matters and the order to do it in.

What “running IT yourself” actually means

It doesn’t mean becoming a technician. Modern business technology lives in the cloud and is built to be managed by normal people, not specialists. “Running IT yourself” means owning six things: your devices, your accounts and email, your security, your data backup, your everyday software, and your support plan for when something breaks. Get those six right and you’ve covered what an IT department would for a small team – at a fraction of the cost.

If you’re still weighing whether to do this at all, our honest breakdown of whether small businesses need an IT department walks through DIY vs an MSP vs a consultant. For most early-stage businesses, DIY plus the occasional expert is the right answer.

1. Get the foundations right

Everything sits on four basics: your own domain, business email on that domain (not a personal Gmail), an individual account for every person (never shared logins), and business-grade devices that still receive security updates. Shared logins and a personal-email business are the two things I most often have to untangle – fix them first and the rest gets easier. Our complete technology checklist covers the full foundation step by step.

2. Pick one platform: Microsoft 365 or Google Workspace

This single choice shapes your email, files, video calls, and a lot of your security. Pick one and commit – don’t run both. Microsoft 365 suits teams that live in Office and want desktop apps; Google Workspace suits browser-first teams who value fast collaboration. Either is fine; mixing them is the mistake. Our Microsoft 365 vs Google Workspace comparison settles the choice for your situation.

3. Do the security basics (this is the part people skip)

You don’t need an enterprise security budget – you need to do a handful of things consistently. In priority order:

• Turn on multi-factor authentication (MFA) everywhere. Free, and it blocks the large majority of account takeovers even if a password leaks. Start with email.
• Use a password manager. It ends reused and shared passwords – the #1 cause of small-business breaches. I recommend NordPass for small teams.
• Keep everything updated automatically.
• Talk to your team about phishing. The human is the target now.

That short list does most of the work. For the complete version, follow our small business cybersecurity checklist.

4. Back up your data (because the cloud isn’t a backup)

This is the one that saves businesses, and the one most owners get wrong. Microsoft 365 and Google Workspace are not a backup – they sync your data, but they won’t save you from ransomware, a deleted account, or a corrupted file past their short retention window. Use a proper third-party backup of your email and cloud files; I use IDrive. Then run one test restore so you know it actually works before you ever need it.

5. Keep your software stack lean

Most small teams need a small, boring set of tools used well – not fifteen overlapping apps. Your M365 or Workspace plan already includes chat, video, and storage; don’t pay twice for those. Add a simple task tool and somewhere to document how things are done, and stop there. If money’s tight, our budget tech-stack guide shows where to spend and where to save.

6. Have a plan for when something breaks

Running IT yourself doesn’t mean being alone. Know in advance who you’ll call for the hard problems – a trusted consultant you can pay by the hour beats a panicked Google search at 9pm. Keep a simple document of your setup (accounts, where things live, key contacts) so the business doesn’t live only in your head. That’s the difference between “no IT department” and “no plan.”

When you’ve outgrown DIY

DIY isn’t forever. Around ten-plus users, heavier complexity, compliance requirements, or simply when managing tech is pulling you away from running the business – that’s when a consultant or managed provider starts to earn its fee. Revisit the decision yearly. Plenty of businesses start fully DIY, add a consultant as they grow, and only later move to managed IT. The goal isn’t to avoid help forever; it’s to not pay for it before you need it.

Your starting point

If this feels like a lot, don’t try to do it all today. Do the security basics this week (MFA, a password manager), sort your backup next, and work through the rest steadily.

Frequently asked questions

Can you really run a business without an IT department?

Yes – most small businesses do. Modern cloud tools are built to be managed by non-specialists. The key is doing the security and backup basics properly so “no IT department” doesn’t quietly become “no protection.”

What’s the most important thing to set up first?

Multi-factor authentication on your email and key accounts. It’s free, takes minutes, and prevents the most common type of attack on small businesses.

How much does running IT yourself cost?

Mostly just your software: a per-user Microsoft 365 or Google Workspace plan, a password manager, and a backup service – each a few dollars per user per month. The biggest cost is your time, not money.

When should I hire IT help?

Consider outside help around ten or more users, when you run complex systems, handle regulated data, or when managing tech eats time you should spend on the business. Below that, DIY plus an occasional consultant is usually enough.
