For most small teams, Microsoft 365 Business Standard is a suitable starting point, offering desktop Office apps, Exchange email, Teams and SharePoint for a reasonable monthly per-user fee. If your business handles sensitive client data or manages several company devices, step up to Business Premium for the added protection. Either way, you can trial before you commit, or ask a partner to set it up properly from day one.
TL;DR:
- Most small businesses will find Microsoft 365 Business Standard sufficient, with full desktop apps, while Business Premium adds essential security features for handling sensitive data.
- Additional costs like Copilot, backup solutions, or licences for shared devices should be factored into the budget, especially as team size grows beyond 10 users.
- Upgrading from Standard to Premium is straightforward and can be done per user, enabling flexible security and device management as business needs evolve.
- Native security features like multi-factor authentication and device encryption are available across all plans and should be activated immediately for basic protection.
- A proper migration with professional support minimises downtime and ensures correct setup of email, file sharing, and security, especially when scaling or switching plans.

Microsoft 365 plans for business at a glance
Picking between four plan names that all sound similar is where most small business owners get stuck. Here’s the quick version, so you know which section below is worth your time.
- Business Basic: web and mobile versions of Word, Excel, PowerPoint and Outlook, plus Exchange email, Teams and OneDrive. No desktop app installs. Best for lean teams working mostly from browsers or phones, and the cheapest way into the ecosystem.
- Business Standard: everything in Basic, plus fully installable desktop apps for Windows and Mac, and SharePoint for shared document libraries. Best for teams who need to work offline occasionally, or who just find desktop Word and Excel faster than the browser versions.
- Business Premium: everything in Standard, plus Microsoft Defender for Business, Microsoft Intune device management, and Entra ID identity protection features. Best for businesses managing several laptops or phones, or handling data that needs stronger protection.
- Microsoft 365 Apps for business: apps-only licensing with no Exchange email or Teams bundled in. Best for anyone who already has email sorted elsewhere and just wants the Office apps.
Every one of these business plans supports up to 300 users, which covers the overwhelming majority of small and medium UK businesses. Cross that threshold and you’re into enterprise-tier licensing, a different conversation entirely.
Billing runs per user, per month, and you choose whether to pay monthly or commit annually. All four plans include 1 TB of OneDrive storage per user, with SharePoint adding pooled storage on top for shared team libraries.
One thing worth flagging before you go further: Microsoft Copilot isn’t automatically bundled into every plan tier. It’s positioned as an add-on or selectively included feature depending on which plan and licence combination you choose, so treat it as a possible extra line on your invoice rather than something you already own the moment you sign up for Microsoft 365 for business.
What’s actually included in each Microsoft 365 plan
Knowing the plan names is one thing. Knowing what you can actually do with each one is what makes the decision easier, so here’s the breakdown by real capability rather than marketing copy.
-
Microsoft 365 Business Basic. You get Exchange Online for professional email on your own domain (so no more sending invoices from a Gmail address), Microsoft Teams for calls and chat, OneDrive for cloud storage, and browser or mobile-only versions of Word, Excel and PowerPoint. There’s no desktop install here. If your team works from laptops with solid broadband and rarely needs to edit a spreadsheet on a train with no signal, this gap barely matters. A sole trader answering client emails from a phone, or a small delivery team coordinating jobs through Teams chat, gets full value from Basic without paying for apps they won’t install.
-
Microsoft 365 Business Standard. This is where desktop apps enter the picture. You get fully installable versions of Word, Excel, PowerPoint and Outlook for Windows and Mac, on top of everything Basic offers, plus SharePoint for building shared document libraries your whole team can access. The difference shows up in ordinary moments: two colleagues co-authoring a proposal in real time inside desktop Word, a bookkeeper running complex formulas in Excel that the browser version handles clumsily, or a small marketing team storing brand assets in a shared SharePoint site instead of emailing files back and forth. Standard is the plan most growing small businesses land on, because it removes the “why can’t I do this offline” friction that Basic eventually creates.
-
Microsoft 365 Business Premium. Take everything in Standard and add three specific security layers: Microsoft Defender for Business for threat protection across devices and email, Microsoft Intune for managing and securing company phones and laptops remotely, and Entra ID features for stronger identity and access control. This matters the moment your business has more than a couple of company-owned devices in circulation, or you’re storing information you’d genuinely be in trouble for losing. A firm managing a fleet of ten laptops used by field staff can wipe a lost device remotely through Intune. An accountancy practice handling client financial data gets encryption and conditional access policies that Standard simply doesn’t offer. Premium costs more per user, but it’s solving a real risk, not adding shine.
-
Microsoft 365 Apps for business. This is the odd one out because it strips away Exchange email, Teams and SharePoint entirely and just gives you the installable Office apps. It suits a business that already runs email through another provider, perhaps a legacy setup they’re not ready to migrate, but wants the familiar desktop Office experience for staff. Worth knowing it exists, but for most readers weighing up Microsoft 365 for small business as a genuine unified system, this plan isn’t the answer, since you lose the collaboration tools that make the ecosystem worth adopting in the first place.
To put the day-to-day difference in plain terms: imagine a five-person design studio. On Basic, they’re drafting client proposals in browser Word, which works but feels clunky for anything with heavy formatting. Move them to Standard and the same proposal gets built in desktop Word with full formatting control, then shared via SharePoint so the client-facing folder stays organised rather than scattered across five inboxes. Add Premium if that studio starts handling client contracts with personal data attached, since Defender and Intune close the gap between “we use cloud tools” and “we use cloud tools responsibly.”
Small webinars and client presentations can run through Teams on every plan tier, so that’s rarely the deciding factor. What decides it, almost every time, is whether your team needs offline desktop apps and whether your device fleet needs remote management.
How much does Microsoft 365 cost for a small business?
Microsoft charges per user, per month, and you choose between paying monthly or committing to an annual plan (often at a lower effective rate, paid either upfront or spread across the year). Prices and promotional offers shift regularly, so always check the live Microsoft 365 pricing page before budgeting, rather than relying on a figure you read somewhere months ago.
Pro Tip: Set a calendar reminder to review your Microsoft 365 subscription every 12 months. Microsoft periodically adjusts prices and rolls out new bundles, and businesses that never revisit their plan often keep paying for Premium when half their team could sit happily on Standard.
Here’s how the maths generally works out as your headcount grows, using multipliers rather than fixed figures since your exact bill depends on the plan mix, billing frequency and any add-ons you layer on:
- 5 users: if everyone’s on the same plan, your monthly cost is simply that plan’s per-user price multiplied by five. Small teams often mix Basic for admin staff and Standard for anyone producing client-facing documents.
- 10 users: costs scale linearly, but this is usually the point where businesses start asking whether a few users genuinely need Premium’s security features while others are fine on Standard, splitting the licence mix to control spend.
- 25 users: at this size, device management stops being optional in practice. Losing track of which laptop has which security patch becomes a real operational risk, which is exactly the gap Business Premium closes.
Two things push your total above the headline per-user price. First, Copilot is generally an add-on rather than an automatic inclusion, so factor that in separately if you want AI assistance baked into Word, Excel and Outlook. Second, shared devices and service accounts (a shop till, a reception PC used by rotating staff) usually still need their own licence, since Microsoft licenses by user or device, not by desk.
Choosing the right Microsoft 365 plan for your business
There’s no single “best” plan, only the plan that matches how your business actually operates. Before you buy, run through this checklist:
- How many people need active accounts, and is that number likely to grow past 20 within the year?
- Does your team need offline desktop apps, or is everyone comfortable working entirely in a browser?
- Are staff using company-owned laptops or phones that would benefit from remote management if lost or stolen?
- Do you handle data that carries a real compliance or client-confidentiality obligation?
- What’s your realistic monthly budget once you’ve factored in any Copilot add-on?
Matching those answers to a plan gets easier once you see how it plays out for businesses shaped like yours.
The sole trader or microbusiness. One or two people, working from a laptop and a phone, sending invoices and the occasional proposal. Business Basic covers this comfortably, since browser-based Office and a professional email address solve 90% of what a business this size needs, and there’s little value in paying for desktop installs nobody will use daily.
The trades or field team. Five to fifteen people, several company vans or shared tools, staff who need to check job sheets and send quotes from a site with patchy signal. Business Standard is usually the sweet spot here, offline desktop Word and Excel matter when you can’t rely on connectivity, and SharePoint gives the office a shared library of job records everyone can reach.
The creative agency or consultancy. Client-facing work, shared design or document files, tight deadlines that depend on real-time co-authoring. Standard covers the collaboration side well; if the agency also stores signed client contracts or financial data, Premium’s protection is worth the jump.
The regulated professional services firm. Accountants, solicitors, healthcare-adjacent businesses, anyone with a genuine data-protection obligation attached to client records. Business Premium isn’t optional here in any meaningful sense. Defender, Intune and Entra ID features exist specifically to reduce the risk that a lost laptop or a phishing email turns into a data breach with regulatory consequences.
Before you buy, ask yourself a few less obvious questions too: who in your business will actually manage the admin centre once it’s set up? Does anyone already have backup practices in place, or are you assuming Microsoft backs everything up forever (it doesn’t, by default, forever)? And are you buying for where the business is today, or where it’ll be in eighteen months? A five-person team growing toward fifteen is often better served buying Standard now and planning the Premium upgrade path early, rather than overpaying for security features three people don’t yet need.
Security and device management explained
Business Premium’s extra cost buys you three specific, concrete tools, not a vague promise of “better security.” Here’s what each one actually does.
Microsoft Defender for Business watches for malicious email attachments, phishing links and malware across your devices, and can isolate a compromised machine before it spreads damage further. Microsoft Intune lets an administrator push security settings to every company phone and laptop remotely, and wipe a device clean if it’s lost or an employee leaves on bad terms. Entra ID (Microsoft’s identity platform) handles who can access what, enforcing rules like requiring multi-factor authentication before anyone logs into company email from an unrecognised device.
Even businesses staying on Basic or Standard should take a few immediate steps that cost nothing extra:
- Turn on multi-factor authentication for every account, today, not next quarter.
- Enable device encryption on every company laptop, which is usually a one-click setting on modern Windows and Mac machines.
- Apply Defender-based email filtering wherever it’s available on your plan tier to catch phishing attempts before they reach an inbox.
Microsoft’s own security guidance treats MFA and Defender protections as baseline, not optional extras, regardless of business size.
| Feature | What it does | Available from |
|---|---|---|
| Multi-factor authentication | Blocks logins from unrecognised devices without a second verification step | All business plans |
| Microsoft Defender for Business | Filters malicious email and isolates compromised devices | Business Premium |
| Microsoft Intune | Manages and remotely wipes company devices | Business Premium |
| Entra ID access controls | Enforces identity and access rules across the business | Business Premium |
If your business handles payment details, health information, or client contracts with personal data attached, Premium’s cost stops being a luxury and becomes a reasonable insurance policy against a breach that could cost far more in fines or lost trust.
Migration and getting started with Microsoft 365
Rolling out Microsoft 365 for small business doesn’t need to be chaotic if you follow the steps in order rather than jumping around.
- Buy your licences through the Microsoft 365 admin centre or a partner, choosing the plan mix that matches your team’s roles rather than putting everyone on the same tier by default.
- Verify your domain, proving ownership of your business’s email domain so Microsoft can route mail correctly.
- Set up Exchange Online and create mailboxes for each user.
- Migrate existing mailboxes, moving historic email and calendar data across from your old provider.
- Deploy desktop apps to company machines if you’re on Standard or Premium.
- Set up OneDrive and SharePoint structures so files land in the right shared locations from day one, rather than scattered across individual desktops.
- Enable backup, since Microsoft’s native retention isn’t the same as a proper backup strategy, a distinction worth understanding before you assume everything’s protected forever.
The most common pitfalls are DNS timing (email can go quiet for a few hours mid-migration if records propagate slowly), oversised legacy mailboxes that take longer to move than expected, and old email archives nobody remembered existed until they went missing. None of these are dealbreakers, but they catch out businesses attempting a DIY migration on a Friday afternoon with no fallback plan.
Microsoft’s own documentation recommends contacting a Microsoft Partner for anything beyond a straightforward small migration, and for good reason: a partner engagement typically includes planning the domain cutover, running the mailbox migration overnight to limit disruption, and being on hand if something breaks rather than leaving you googling error messages mid-morning. Our own step-by-step email migration guide walks through the process in more depth if you’re weighing up doing it yourself.
Scaling up or changing plans as your business grows
Nothing about your Microsoft 365 setup is locked in permanently, and that flexibility matters more than most buyers realise at the outset. Upgrading from Basic to Standard, or Standard to Premium, is usually a straightforward change inside the admin centre, applied per user rather than forcing a business-wide switch overnight. That means you can move just the three people handling sensitive contracts onto Premium while the rest of the team stays on Standard, rather than paying the higher tier across the board.
The trigger points worth watching for: crossing from a handful of company devices into double digits (device management stops being a nice-to-have), taking on a client contract with data-protection clauses attached, or growing toward the 300-user ceiling where enterprise plans become the next conversation. None of these need to catch you off guard if you revisit your plan mix annually rather than assuming the setup you bought on day one still fits three years later.
Downgrading works too, and it’s worth doing honestly. If half your Premium licences are sitting on staff who never touch a company device outside the office, that’s money better spent elsewhere. A quick audit of who actually uses which feature, once or twice a year, keeps your Microsoft 365 spend matched to what your business genuinely needs rather than what felt safest at signup.
Connecting Microsoft 365 to the tools you already use
Microsoft 365 rarely sits in isolation. Most small businesses run it alongside accounting software, a CRM, and whatever booking or project tools keep daily operations moving, and the good news is that integration between these systems has become far less painful than it used to be.
Outlook and Teams both support add-ins that pull data from accounting platforms directly into your inbox or chat, useful if you want invoice status visible without switching apps constantly. SharePoint and OneDrive connect to a wide range of project management and e-signature tools, so a contract can move from drafted, to signed, to filed without leaving the Microsoft ecosystem entirely. Teams itself has become something of a hub for smaller businesses, with third-party apps for scheduling, customer support and even lightweight helpdesk functions bolting on directly.
Where this gets genuinely useful is CRM integration. If your business relies on WhatsApp, email and phone enquiries all landing in different places, connecting that activity to your Microsoft 365 calendar and contacts saves the ten minutes a day most small business owners lose copying details between systems. A platform like SmartFlowCRM is built around exactly that kind of channel consolidation, worth knowing about if lead management currently means checking three separate inboxes before you can call anyone back.
What Microsoft 365 really costs once you add everything up
The per-user, per-month price on Microsoft’s plan page is the starting point, not the finish line. A handful of extras tend to appear once a business is a few months into using Microsoft 365 properly, and it’s worth budgeting for them upfront rather than being surprised later.
Copilot, as already covered, sits outside most core plans as an add-on rather than a built-in feature, so add that cost separately if AI assistance in Word and Outlook matters to your team. Backup is the other big one: Microsoft’s native retention policies aren’t a substitute for a proper backup solution, and most small businesses eventually pay for a dedicated backup service once they understand the difference, something our Microsoft 365 backup guide covers in detail.
Shared devices, like a reception PC or a warehouse scanner, often still need their own licence even though no single person “owns” that device, a detail that catches out businesses budgeting purely by headcount. Annual billing usually beats monthly on a per-user basis, so switching billing cadence is often the simplest saving available. And if you’re bringing in a partner for setup or migration, that’s a one-off or ongoing service cost sitting outside Microsoft’s own invoice entirely, worth weighing against the hours it would take your own team to do it, and get it wrong, without help.
How we think about Microsoft 365 setup at TTOY Digital
We come to Microsoft 365 projects from the same angle as everything else we do for small businesses: figure out what’s actually slowing the client down before recommending anything. That usually means a short conversation about how the team currently handles email, files and client communication, then mapping that reality onto the plan that fits, rather than defaulting everyone to Premium because it sounds safest.
If your business is weighing up a partner for setup versus doing it alone, the honest answer is that a straightforward five-user Basic rollout rarely needs one. Once you’re migrating legacy mailboxes, setting up device management, or trying to connect Microsoft 365 to a CRM workflow, that’s where a partner engagement typically pays for itself in avoided downtime and fewer support calls in month one.

Managed Microsoft 365 setup from TTOY Digital
TTOY Digital is the alternative to figuring out Microsoft 365 migration by trial and error, and to paying for a plan tier your team doesn’t actually use. Where a DIY rollout risks DNS hiccups, an oversised mailbox migration eating a whole weekend, or a Premium subscription nobody configures properly, we set it up once, correctly, and explain what we did in language that doesn’t require an IT background to follow.
Our Microsoft 365 service covers mailbox migration, plan selection based on how your team actually works, Defender and Intune configuration for businesses that need Premium’s protection, and integration with SmartFlowCRM if your leads currently live across WhatsApp, email and a notebook by the till. We work alongside partners in the wider digital ecosystem, including agencies like ClickXpand supporting marketing teams that run on Microsoft 365 day to day.
We aim to recommend plan tiers that fit your business needs without unnecessary upselling. Get in touch through our services page and we’ll talk through what your business actually requires before anyone recommends anything.

What’s the cheapest way to get Microsoft Office 365?
Microsoft 365 Business Basic is the lowest-cost business plan, giving you web and mobile Office apps, Exchange email, Teams and OneDrive without desktop installs. It suits businesses that work mostly from a browser and don’t need offline access.
How much does Microsoft 365 business cost overall, including extras?
Beyond the per-user licence fee, expect potential extra costs for Copilot (typically an add-on rather than included), a dedicated backup service, and licences for any shared devices like a reception PC. Annual billing is usually cheaper per user than paying monthly.
What’s the difference between Microsoft 365 and a “Microsoft business” plan?
“Microsoft 365” is the umbrella name for the whole subscription family, while specific business plans (Basic, Standard, Premium, Apps for business) are the individual tiers within it. There’s no separate product simply called “Microsoft business” beyond these named plan tiers.
Which Microsoft 365 plan includes Copilot?
Copilot availability varies by plan and is generally offered as an add-on rather than a guaranteed inclusion across every tier. Check the current Microsoft 365 plan and pricing page to confirm which licence combination includes it before budgeting.
