If you already pay for Microsoft 365, Teams is usually the sensible default. If most of your calls are with clients, customers or people outside your company, and you want them to join with as little fuss as possible, Zoom is usually the easier choice. Most small businesses can decide in about ten minutes by answering two questions: what do you already pay for, and who sits on the other end of your calls?
We spend a lot of time setting up Microsoft 365 for small businesses across Derbyshire and beyond, so we see this decision from both sides. Here is how the two tools really differ day to day, without the feature-list fog.
TL;DR
- Teams is a collaboration hub (chat, files, tasks, meetings) that comes with Microsoft 365. Zoom is a meeting-first platform with collaboration add-ons.
- Zoom is generally easier for outside guests to join. Teams is stronger for internal work, especially if you live in Outlook, Word and SharePoint.
- Both advertise a 99.9% uptime commitment, and both offer solid security basics. Your decision is rarely about reliability.
- If you already pay for Microsoft 365, Teams costs you nothing extra. Paying for Zoom as well only makes sense if outside meetings or webinars are a big part of your week.
- You can run both. Plenty of small firms use Teams inside the business and Zoom for the occasional client or webinar.

The core difference in one minute
The two products started from different places, and it still shows.
Teams is a collaboration platform with persistent chat, file sharing through SharePoint and task tracking in Planner. Zoom is a meeting platform that has grown collaboration features around it, according to a UK comparison aimed at small businesses. Another UK write-up puts it the same way: Teams is a hub where meetings are just one feature, while Zoom is built meeting-first.
It is worth knowing that each company tells the story its own way. Zoom presents its Workplace product as an all-in-one platform and describes Teams as mainly optimised for Microsoft 365 users. Microsoft describes Teams as a work platform that brings chats, channels, meetings, calling and apps together. Both are fair descriptions of what each does best.
The practical version: Teams is where your team works. Zoom is where you meet people.
Why so many companies end up on Teams
The biggest reason is boring and very sensible: money and admin. Businesses tend to move to Teams, or consolidate into it, because it is already covered by their Microsoft 365 licences, which cuts costs and means one less system for someone to look after.
That same source notes the common split in usage: Teams for internal collaboration, Zoom for video conferences with other companies.
Imagine Sarah, who runs a six-person bookkeeping firm. Her team already lives in Outlook and shares spreadsheets through OneDrive. Adding a separate video tool means another login, another bill and another thing to explain to a new starter. For her, Teams is a no-brainer, because the files, calendar and calls already sit in one place.
If that sounds like you, our guide on which Microsoft 365 plan UK small businesses actually need is a good next read before you spend anything.
Joining a meeting: where Zoom pulls ahead
Here is the part that matters if you meet customers on screen. Zoom is easier for external attendees to join and has historically coped slightly better with poor connections, while Teams is more feature-dense and its browser guest access can confuse people. Zoom also lets guests join from a browser link without downloading anything or creating an account, and one 2026 guide called that the lowest barrier of any major video platform.
That matters more than it sounds. If you are a plumber’s merchant doing a quote review with a customer in their seventies, or a consultant meeting a new lead for the first time, the first thirty seconds set the tone. A guest wrestling with an install is not the impression you want.
Teams has improved on this, and for people who already use it, joining is straightforward. But if guests are a big share of your calls, test it yourself: send a Teams link and a Zoom link to a friend who has neither installed, and watch what happens.
Chat, files and working together
This is where Teams earns its place. Persistent chat, channels for projects or clients, shared files that live in SharePoint and OneDrive, and tasks in Planner are all part of one workspace. For a business already on Microsoft 365, that integration is described as highly cost-effective.
Zoom is not a one-trick tool. Zoom Workplace combines meetings with chat and other services, and Zoom Phone supports text and group SMS across multiple clients, whereas Teams SMS relies on third-party services. Zoom’s own materials list whiteboard, mail, calendar, scheduler, rooms and notes among its wider workplace features.
If you are weighing up calls and phone numbers as well, we cover that side in our Teams phone guide for UK small businesses.
Quick comparison
| What you care about | Microsoft Teams | Zoom |
|---|---|---|
| Best at | Internal collaboration, files, chat | Meetings with people outside your company |
| Guest joining | Works, but can confuse some guests in a browser | Browser link, no account or download needed |
| Microsoft 365 fit | Built in | Separate product |
| Uptime commitment | 99.9% SLA | 99.9% SLA |
| Free plan | 5 GB storage, group calls up to 60 minutes, 100 participants | Basic: up to 100 participants, 40-minute limit |
| Paid meeting length | Up to 30 hours | Pro: up to 30 hours |
| Webinars | Available on higher Microsoft 365 plans | Dedicated webinar licences, view-only attendees by default |

What each one costs a UK small business
Prices change, so treat the numbers below as a snapshot and check the provider’s page before you buy.
Teams. Microsoft 365 Business Basic is listed at £5.40 per user per month on an annual commitment and includes Teams. Microsoft’s UK page lists it with web and mobile Word, Excel, PowerPoint and Outlook, custom business email, 1 TB of cloud storage and Teams chat, calls and meetings. If you only want meetings, Teams Essentials is aimed at small businesses and offers meetings of up to 30 hours and 300 participants, plus 10 GB of storage per user. The free Teams plan is for one person, with 5 GB of storage and group calls of up to 60 minutes with 100 participants.
Zoom. The free Basic plan supports up to 100 participants but cuts meetings off at 40 minutes. Pro keeps the 100-participant limit, lifts the duration to 30 hours and adds 10 GB of cloud recording, polling, reporting and international dial-in, per Zoom’s own comparison. Larger plans stretch to 500 or 1,000 participants. For current UK prices per licence, check Zoom’s pricing page.
One trap catches people out. Some Microsoft 365 plans are sold in “No Teams” versions to comply with international regulations, which confuses businesses that expected Teams to be included. When you buy, confirm the plan includes Teams.
The money point is simple. If you already have Microsoft 365, Teams is effectively free. Adding Zoom means a second subscription per host, so ask whether outside meetings justify it.
Security and privacy
For most small businesses neither tool is a risky choice. Both support encryption, waiting rooms and ISO 27001 certification. Teams has an edge if you already use the Microsoft security ecosystem (Defender and Entra ID) because management sits in one place, while Zoom offers UK and EU data residency on its paid tiers, according to the UK comparison.
If you handle client data where location matters, such as legal, financial or health-adjacent work, ask your provider in writing where meeting data and recordings are stored and set the admin controls on day one. Your professional body or data protection adviser can tell you what your sector expects.
Limits worth knowing before you commit
Every tool has rough edges, and knowing them lets you set things up properly.
- Zoom’s free 40-minute cap. Fine for a quick catch-up, awkward for a client workshop. A paid licence for the person who hosts removes it.
- Zoom webinars are separate. Hosts and panelists present, attendees are view-only, and microphone, chat, Q&A and polls only appear if the host switches them on. If you run serious webinars, plan for the webinar licence.
- Teams has a lot going on. Channels, chats, teams and apps can overwhelm a new user. A short naming convention and one onboarding session fix most of it.
- Teams guest joining. Agree with clients in advance whether they will use the app or the browser.
How to choose: five questions
- Do you already pay for Microsoft 365? If yes, start with Teams. Use it for a month before buying anything else.
- Who are most of your calls with? Mostly staff and regular suppliers points to Teams. Mostly new clients and the public points to Zoom.
- Do you run webinars or large events? If so, price up Zoom’s webinar licences against what Teams offers on your Microsoft plan.
- How tech-confident is your team? Zoom is simpler to learn. Teams repays the learning curve.
- Do you need chat, files and tasks in one place? That is Teams territory.
For many firms the honest answer is both: Teams as the everyday workspace, Zoom kept for outside calls. That is perfectly reasonable, as long as someone owns the accounts and you are not paying for licences nobody uses.
If your team is spread across countries, a good meeting tool is only half the picture. Our note on hiring remote staff in South Africa is useful when you are planning how a distributed team will actually work together.
Our perspective
We get asked this at least once a month, usually by an owner who has been burned by a pile of subscriptions they barely use.
Our honest view is that the tool matters less than the set-up. A small business that picks Teams, names its channels sensibly, puts files in one place and connects its calendar will get more from it than a business that buys the “better” app and leaves it half configured. That is why we set up and manage Microsoft 365 for small businesses rather than just handing over licences: email, calendar, files and Teams working as one thing, with someone local you can phone when it misbehaves.
Where a business also meets lots of clients on video, we would rather you keep it simple: Teams for the daily work, and a plain, tested join process for guests. And if your leads arrive through email and WhatsApp as well as calls, that is where our SmartFlowCRM comes in, because meetings are only useful if the follow-up does not fall through the cracks.

FAQ
Why do companies use Teams instead of Zoom?
Mostly because Teams is already included in their Microsoft 365 licences, so it adds no cost and keeps chat, files, calendar and calls together. It also means one less system to manage. Zoom stays popular for calls with people outside the company.
Is Microsoft Teams as good as Zoom?
For internal work, Teams is often the stronger tool, thanks to persistent chat, SharePoint files and Planner. For meetings with outside guests, Zoom is generally smoother to join. Neither is better in every case, so match the tool to who you meet most.
Can I use Teams and Zoom together?
Yes. Many small businesses run Teams internally and Zoom for client calls or webinars. Just watch the licences so you do not pay for seats nobody uses.
Is the free version enough for a small business?
Possibly for light use. Zoom’s free plan stops meetings at 40 minutes, and the free Teams plan is designed for one person with group calls of up to 60 minutes. Regular client calls usually justify a paid plan.
