What's Actually Included in Microsoft 365 (And Do You Need It)?

Most business owners are already paying for Microsoft 365, or something they call Microsoft 365, without being entirely sure what they're actually getting for it. That's not a knock on anyone, Microsoft has renamed plans, moved features around, and turned AI into a separate paid extra, all within the space of a year or two.

Short version: the tiers mainly differ in whether you get installed desktop apps and how much built-in security comes with it, AI is never included by default, and most small businesses land on Standard or Premium depending on how sensitive the data they handle actually is.

Even people who set their own subscription up originally can end up unsure exactly what's included versus what they'd need to add separately. If you've never actually sat down and compared the tiers properly, here's what's genuinely in each one, and a straight answer on whether your business needs it at all.

What Microsoft 365 actually is

At its core, Microsoft 365 is Microsoft's subscription bundle for businesses. Instead of buying Word or Excel once and owning that copy forever the way people used to, you pay per person, per month, and in return you get a mix of the Office apps, a professional email address on your own domain, cloud storage, and, depending on the plan, a set of security tools layered on top. It's less a single product and more a bundle of several Microsoft products sold together under one name, which is exactly why the tiers matter so much. Two businesses can both say they "have Microsoft 365" and be using two completely different sets of tools for two very different prices.

A lot of small NZ businesses aren't actually comparing Microsoft 365 against a competitor. They're comparing it against a patchwork of free tools, a personal Gmail address doing double duty as the business email, files scattered across whatever device last had them, and video calls happening through whatever app a customer happens to prefer that week. Against that baseline, even the entry tier is a genuine step up.

Business Basic: the browser only option

Business Basic is the cheapest tier, and it gets you the web and mobile versions of Word, Excel, PowerPoint, and Outlook, not the installed desktop programs. You also get professional business email through Exchange with a decent sized mailbox, 1 TB of cloud storage through OneDrive, Microsoft Teams for calls and chat, and SharePoint for shared files. For a business that mostly works out of a browser or off a phone and doesn't need the full desktop software, this covers the basics properly. For anyone who wants to open Word or Excel as an actual installed program on their laptop, it falls short, and that gap is usually the first thing that pushes people up to Standard.

Business Standard: the default for most small businesses

Business Standard includes everything in Basic, plus the full installed desktop versions of Word, Excel, PowerPoint, and Outlook, along with a couple of smaller extras like Clipchamp for basic video editing. This is the plan most typical small businesses end up on, since it covers real desktop software plus email, storage, and Teams, without paying for security features a two or three person operation may not feel they need yet.

Business Premium: Standard plus real security

Business Premium includes everything in Standard, then adds a genuine security layer: Microsoft Defender for Business for antivirus and ransomware protection, Intune for managing and securing staff devices, advanced identity protection for logins, and stronger email filtering against phishing attempts. None of that is exciting to read about, but it matters a lot more than it sounds once you're handling customer payment details or personal information, or letting staff access work email and files from their own phones. In practical terms, it's the difference between a lost or stolen staff laptop turning into a real problem, and being a locked device that gets wiped remotely before anyone else ever sees what was on it.

Apps for Business: the odd one out

This one trips people up. Apps for Business gives you the full installed desktop Office apps and cloud storage, but it deliberately leaves out business email, Teams, and SharePoint. It exists for businesses that already have their email sorted elsewhere, through a website host or a different provider, and just want proper installed Office software on top. It's a narrow fit, but the right one if that's genuinely your situation.

The part almost everyone assumes wrong

None of these plans include Microsoft's AI features by default. Copilot for Microsoft 365 is sold as a separate add on, on top of whatever plan you're already paying for, and you need to already be on Standard or Premium to buy it at all. If part of the reason you're considering Microsoft 365 is the AI features you've heard about, know going in that it's an extra cost layered on top, not something that comes bundled in with the plan itself.

What it actually costs

Pricing in New Zealand roughly runs from around $7 a user per month for Basic up toward $30 a user per month for Premium, with Standard sitting in between. The exact number depends on who you buy through and whether you commit annually or pay month to month, and GST is generally on top of whatever headline figure you see advertised. It's worth getting an actual quote for your specific business size rather than assuming the advertised price is the final one, since resellers and commitment terms genuinely move the number around.

Do you actually need it

If you're currently running your business email through a free personal account, a Gmail or similar address with your business name jammed in front of it, that alone is worth fixing before anything else. A professional address on your own domain changes how customers see you, and it's one of the clearer signals that a business is properly set up rather than running out of someone's back pocket.

If it's just you, working mostly from your phone between jobs, Basic or Standard will genuinely cover what you need, and the desktop apps in Standard are worth the small jump up if you ever sit down at an actual computer to do quotes or paperwork.

If you've got staff, if customers hand over personal or payment details, or if work happens on phones and laptops that could get lost or stolen, Premium's security tools stop being a nice to have. The cost of a genuine data breach or a compromised account, in time, reputation, and hassle, is a lot higher than the monthly difference between Standard and Premium.

If you've already got email sorted through your website host and just want proper Office apps, Apps for Business is a reasonable, narrower option. It's the one plan on this list worth actively choosing only if you already know that's your situation, rather than defaulting to it because it sounds simpler.

One more thing worth knowing: you don't have to put every staff member on the same tier. It's common to put office based staff who handle sensitive data on Premium while someone mostly out on the tools only needs Basic. Mixing tiers by role is a legitimate way to control cost without under protecting the people who actually need it.

Where ForgePoint fits in

Microsoft 365 setup is part of what we do alongside websites, and the plan that actually suits a two person plumbing outfit is rarely the same one a template or a generic guide would push you toward by default. If you want a straight answer on which tier fits your business rather than working through all of this yourself, that's a quick conversation.
