Key takeaways
- Slack bills per active member, not per team. Pro runs 6.75 € per user per month on annual billing, 8.25 € monthly (checked 2026-07-25). Every hire raises the invoice in a straight line.
- EU data residency starts at Business+. That tier costs 15 € per user per month annually, so a 10-person team pays 1,800 € a year before anyone opens a channel.
- The free plan hides messages after 90 days. It is the single most common reason teams describe for moving to Pro, and large communities routinely stay on free and live with the cap instead.
- Chat is rarely the only line item. Paying for team chat alongside scheduling, video and CRM is what makes the annual number hurt, which is why bundled suites price the same job differently.
Slack publishes its prices openly, so the surprise is not the list price. It is the two jumps almost every growing team makes: from free to Pro once the 90-day history limit bites, and from Pro to Business+ once someone in legal asks where the messages are stored. This breakdown prices both jumps at real headcounts.
How Much Does Slack Cost?
Slack has four plans. The figures below are the euro list prices shown on Slack's own pricing page, checked 2026-07-25. The plan structure is identical in other currencies.
| Plan | Price per user / month |
|---|---|
Free | 0 € |

At annual billing that works out to 67.50 € a month for ten people on Pro and 150 € a month on Business+. At 100 people the same two tiers cost 675 € and 1,500 € a month, or 8,100 € and 18,000 € a year. There is no volume discount below Enterprise+, so the per-seat rate holds steady as the team grows.

Slack Pricing Plans: A Breakdown
Free: 0 € per user
Free runs indefinitely with no user cap. The limits sit elsewhere: 90 days of visible message history, up to 10 connected apps, huddles restricted to one-to-one, Slack Connect limited to 1:1 external messages, and single sign-on only through Google OAuth. Enough for a quarter-long project team. Not enough for a company that makes decisions in channels and needs to find them a year later.
Pro: 6.75 € per user
Pro lifts the history limit, opens unlimited app connections, makes huddles group-capable and adds SAML-based single sign-on with SCIM provisioning. Support commits to a four-hour first response. What Pro does not give you is any say over storage location, so a Pro workspace has no region choice at all.
Business+: 15 € per user
Business+ is the tier European buyers with data-residency requirements end up on. It opens the region picker, including Frankfurt, and adds multi-SAML, compliance exports covering all messages, and priority support. That step from 6.75 € to 15 € per head is the most expensive single move in the price list, and for most teams it buys a legal answer rather than a daily-use feature.
Enterprise+: contact sales
Enterprise+ targets large and regulated organisations: Enterprise Key Management, HIPAA-configurable storage, per-user data exports, and a dozen SSO options. No list price is published, so the number comes out of a sales conversation.
What Hidden Costs Does Slack Have?
- Data residency is a tier jump, not a checkbox. Frankfurt as a storage region requires Business+ or above. For ten people that is 1,800 € a year instead of 810 € on Pro, without adding a single feature the team touches day to day.
- The region picker does not cover everything. Slack stores messages, canvases, snippets, uploaded files, the search index and app-generated content in the chosen region. Member profiles, workspace and channel membership data, seat and usage records, and sanitised analytics logs may sit outside it, and flagged content can be stored in the United States for policy enforcement.
- The promo has a seven-day window. The advertised 50% off for three months applies only if you buy Pro or Business+ online within seven days of creating the workspace, and annual plans are excluded. From month four the list price applies, which quietly breaks any first-year budget built on the discounted figure.
- You cannot upgrade one seat. Plans apply to the whole workspace, so an individual who needs older messages back has to get the owner to upgrade everyone. One r/Slack thread on upgrading to Pro has that spelled out by a replying admin, who also notes that the licence count has to include multi-channel guests, not just employees.
- Dormant accounts keep billing. Charges follow active members, so workspaces that never prune deactivated users pay for people who left months ago.

Slack Pros & Cons
Pros
- Mature chat product with channels, threads, huddles, canvases, lists and clips
- Large app directory plus Workflow Builder for no-code automation
- Slack Connect brings partner organisations into shared channels
- Certifications through FedRAMP and HIPAA-configurable storage for regulated buyers
Cons
- The Pro to Business+ step more than doubles the per-seat cost, largely to obtain the region picker
- Free workspaces lose visibility of messages after 90 days, which pushes groups onto paid tiers for archiving alone
- As a Salesforce subsidiary, Slack sits under US jurisdiction and the CLOUD Act regardless of which region stores the data
Who Is Slack Best For?
Slack earns its price for teams that treat chat as a platform: many connected systems, automations running in Workflow Builder, continuous work with external organisations in shared channels. In that setup the per-seat rate buys an integration layer, not messaging.
It is a harder sell for teams that use it as a messaging app. If the daily job is channels, DMs and file sharing, Business+ at 15 € a head funds capabilities that go unused. Cost is also what keeps large groups off paid tiers entirely: in an r/Slack discussion on community pricing, the organiser works out that a 500-member community would run past 3,600 € a month, and several replies confirm that comparable communities simply stay on free and accept the 90-day cap.
Slack Customer Reviews

Slack holds 4.5 out of 5 from 39,201 reviews on G2 (checked 25.07.2026), where reviewers consistently praise the integration depth and search. The recurring complaint in the same profile is cost at scale, which matches the community threads above.
What Is the Best Alternative to Slack?
meetergo is an EU-sovereign suite of 15 apps with no US corporate parent, so data stays under EU law rather than under a transfer mechanism. Team chat is one app in it: channels, direct messages, threads, mentions and file sharing, in the same workspace as bookings, CRM and AI meeting notes. The difference shows up on the invoice more than in the interface. Everything moves through one seat per person, and one data processing agreement replaces five.
An honest limit: meetergo does not match Slack feature for feature. The app marketplace, Workflow Builder, Slack Connect at partner-network scale and Enterprise Key Management have no equivalent here. Teams that push Slack as a platform will lose capability by switching. Teams using it as chat save a subscription and get the storage region without paying for a tier.

Is Slack Worth the Price?
For teams that run their operations through channels and automations, yes. Six to eight euros a head is not an outlier for a product this mature, and the free tier carries short projects fine.
The arithmetic breaks at Business+. European companies arrive there because of a compliance question rather than a feature, then pay more than double per seat for an answer that still leaves profile, membership and analytics data outside the chosen region. When the storage location is the actual reason for the purchase, it is worth pricing vendors where it comes standard. The same test applies to the rest of the stack, which is where breakdowns like Cal.com pricing and the Microsoft Teams alternative comparison come in, and the wider question is covered in this guide to data sovereignty.
