Slack Plan Retirements 2027: Legacy Business+, Enterprise Grid and the Slack AI Add-On

On March 3, 2026, Slack announced that four of its offerings retire on March 1, 2027: the legacy Business+ plan, Enterprise Grid, Enterprise Select and the Slack AI add-on. For each one, Slack's help center says that on your next renewal date after March 1, 2027, you won't be able to purchase it again (Slack feature and plan retirements). If your team is on one of them, your renewal date is now a plan decision. Here's what Slack has said, what it hasn't, and how to use the time.

What Slack is retiring, and when

Slack lists each retirement on its feature and plan retirements page. All four were announced on March 3, 2026, with a retirement date of March 1, 2027, and a status of "Announced" when we checked.

For each plan, Slack's advice is the same: to find the best plan going forward, contact your Account Executive.

What "legacy Business+" means

Slack changed its plans in 2025. Its plan updates article describes a Business+ price change, the introduction of Enterprise+, and advanced AI features bundled with the new Business+ version. The plans it lists today are Free, Pro, Business+ and Enterprise+.

So "legacy Business+" is the earlier version of Business+, not the plan Slack sells now. The same article explains how to check which version you're on. It also says Slack stopped selling the AI add-on on its website, so the retirement mainly concerns existing contracts.

What Slack hasn't said yet

The retirements page covers renewals only. When we checked, it didn't say:

• what happens to your current subscription between now and your renewal,
• which plan a legacy Business+, Enterprise Grid or Enterprise Select workspace moves to,
• or what that plan will cost you.

Those answers come from your Account Executive, so ask early rather than in your renewal month. For Slack's current list prices, see Slack pricing explained.

What it means for your team

Find your renewal date. The change reaches you at your first renewal after March 1, 2027, not on that day. By Slack's wording, a team whose renewal falls in February 2027 renews before the cutoff, while one that renews in April 2027 falls after it. Check your contract or billing settings before you plan around the March date.

Decide where you're going, not just whether to renew. Staying on Slack likely means moving to a current plan, and your Account Executive can tell you which one and what it costs. If you relied on the Slack AI add-on, check which AI features your next plan includes. Slack lists most of them on Business+ and Enterprise+, and enterprise search on Enterprise+ only (Slack help).

Leave time to compare. A forced plan change is a natural point to ask whether Slack is still the right fit. Evaluating an alternative, running a pilot and moving history all take weeks, so start well before your renewal.

If you're a startup, check any partner discounts you qualify for and confirm their eligibility and renewal terms before you sign. If you're considering the Free plan, distinguish history access from retention: Slack limits access to the most recent 90 days and deletes data more than a year old (Free plan limits). See Slack for Startups for more planning considerations.

Questions to bring to your renewal

• When exactly is our next renewal date?
• Which current Slack plan will we move to, and at what price per seat?
• Which features we use today are on that plan, including AI features?
• What do we need from team chat now that we didn't when we signed, such as agents working with us?
• What would it cost to run the same team on another app? See cheaper Slack alternatives for yearly costs by team size.

Where Ando fits

If you're evaluating alternatives, Ando is team chat built for teams that work with AI agents. Agents are members of the workspace, in the same chats as people, with their own name and profile. There are two kinds: an Ando agent, which Ando runs for you, and an external agent, which runs elsewhere, such as a coding agent on your own machine, and connects in (Ando agent vs external agent).

Ando has two paid plans, Pro and Business, and both keep unlimited message history. See pricing for current details. If you're moving from Slack, migrate from Slack covers what to plan for.

Ando won't be the right choice for every team leaving these plans. If you depend on Slack Connect with many outside companies, or on a long list of Slack apps, weigh that before you move.

FAQ

Which Slack plans are being retired in 2027?

The offerings covered here are the legacy Business+ plan, Enterprise Grid and Enterprise Select, plus the Slack AI add-on. Slack announced all four on March 3, 2026, with a retirement date of March 1, 2027.

Does my Slack plan stop working on March 1, 2027?

Slack's page doesn't say that. It says that on your next renewal date after March 1, 2027, you won't be able to purchase the retired plan or add-on again. Ask your Account Executive what happens to your subscription before then.

What is legacy Business+?

The earlier version of Slack's Business+ plan. In 2025, Slack changed the price of Business+ and moved advanced AI features into the new version of the plan. Slack's plan updates article explains how to check which version you're on.

Can I still buy the Slack AI add-on?

Not from Slack's website, which stopped selling it. Slack's retirements page says it can't be purchased at renewals after March 1, 2027.

What should we do before our renewal?

Find your renewal date, ask your Account Executive which plan you'll move to and what it will cost, check which features you'll keep, and compare alternatives with enough time to run a pilot.
