Slack vs Microsoft Teams: which fits in 2026?
Short answer: Slack vs Microsoft Teams: which fits in 2026?. Put the current file, the decision and the next owner in one channel. Basic is 9 USD per paid account a month, or 86 USD a year, with 25 GiB. The trial is 3 days. The iPhone and iPad app is coming soon. The encryption scope is on the security page.
Slack vs Microsoft Teams on price, files, history and meetings. Slack Pro reference 8.75 USD, checked 31 Oct 2026. No invented score.
Short answer. Slack and Microsoft Teams are both team chat, and they are not the same quote. Slack Pro in our calculator is a reference of 8.75 USD per person a month, or 7.25 USD on annual billing, checked against Slack's pricing page on 31 Oct 2026. Teams is sold with Microsoft 365, so a chat seat is not the whole license. Confirm both quotes before you buy.
Slack and Microsoft Teams on the points that change a quote
| Point | Slack | Microsoft Teams |
|---|---|---|
| Price shape | Per-person plans. Pro reference 8.75 / 7.25 USD. | Sold with Microsoft 365. Read the suite price. |
| Files | Slack documents a 1 GB cap on one upload. | Files often sit in SharePoint while the talk is in chat. |
| History | The Free plan limits visible history. | Retention follows the Microsoft 365 settings you already run. |
| Meetings | Huddles and calls exist. A meeting suite is not the product. | Meetings are a reason companies already pay for the suite. |
| Choose it if | You depend on a Slack app you have already tested. | The company already runs identity, files and meetings in Microsoft 365. |
Choose Slack if, choose Teams if
Choose Slack if the team already lives in Slack apps and the quote you were given matches the per-person price on Slack's own page. Choose Teams if leaving Microsoft 365 would split identity, meetings and files. Neither choice is a project checklist. The file and the next step can still live in different products.
A third option when the job is the project file
BusyVault is not required to pick between Slack and Teams. It is a separate product for teams whose problem is keeping the file, the decision and the next step in one channel. Basic is 9 USD per paid account a month or 86 USD a year, with 25 GiB. Pro is 30 USD or 288 USD, with 100 GiB. Extra storage is 0.03 USD per GiB a month. We make BusyVault, and Teams still wins when you need the Microsoft 365 suite.
QUESTIONS
Questions about Slack and Teams
Is Teams cheaper because chat looks included?
Only if you already pay for the Microsoft 365 licenses the team needs. Add-ons and audio conferencing can change the quote. Read Microsoft's current page.
Which file limit is published here?
Slack documents 1 GB for one uploaded file. This page does not invent a Teams upload number. Check Microsoft's current limit before you rely on it.
Do you rank a winner with a score?
No. There is no star rating and no lab score on this page. The verdict is which quote and which suite you already have.
Where does BusyVault fit?
When the daily problem is the project file next to the conversation, not the Microsoft meeting stack. Compare it on its own page, and keep Teams if the suite is the reason you pay.
What to write down before you switch
Read “Slack vs Microsoft Teams: which fits in 2026?” as a buying note for one job, not as a score. Name the file you would actually send, the history you still need to search, and who pays for each account. BusyVault is the hosted app for that job. Other products stay on this page only where the comparison says who runs the server or what one upload allows. There is no star rating and no laboratory winner. Keep the quote you were sent beside any public price printed here.
Files, history and the next owner
On Slack vs Microsoft Teams: which fits in 2026?, keep the file next to the sentence that approved it. Slack documents a 1 GB cap on one upload and, on the Free plan, 90 days of visible history. Those two limits are the public facts this site already cites.
BusyVault bills storage per paid account: 25 GiB on Basic and 100 GiB on Pro. Extra storage is 0.03 USD per GiB a month after you confirm the charge. Basic is 9 USD a month or 86 USD a year. Pro is 30 USD a month or 288 USD a year. One subscription does not cover the team.
The trial is 3 days and 10 GiB. Use it to upload a real file and to search for a decision, not to announce a company-wide move. If the file does not fit or the old decision cannot be found, say so in the channel before you promise the room is the archive.
Where the app runs
BusyVault runs in the browser and can be installed from Chrome or Edge on Windows, macOS and Linux. The Android app is on Google Play and uses the same account. The iPhone and iPad app is coming soon. Enterprise customers can run BusyVault on their own servers under a separate contract. There is no public installer on this site for that path. This page does not claim SOC 2, ISO 27001 or HIPAA.
A check you can finish this week
For Slack vs Microsoft Teams: which fits in 2026?, finish four lines and stop. Line one is the project name. Line two is the channel name. Line three is where the current file lives. Line four is the next owner. Add one rule for meetings: what must be decided live, and what must be written down the same day.
Ask someone who was not on the call to find the file without help. If they open the right channel first, the structure works. If they search three threads and still ask which version is current, move the file to the channel and leave a pointer. Owners and administrators can export a BusyVault backup from workspace or channel settings. After a restore, check the text, the file references and who can open them. Keep the original files until that check passes. Product questions go to the address on the support page.
Suite seat or a project channel
Slack and Teams are not the same bill. Slack publishes a per-person chat price. Teams is sold with Microsoft 365, and the chat seat is not the whole license. Files from Teams chat often sit in SharePoint while the decision sits in a thread. Compare those two layouts on one project you already run, then read the shortlist if neither layout holds the file and the next step together.
