Slack powers collaboration, but managing its licenses is anything but straightforward. Our data shows that nearly half of Slack licenses go unused. Meanwhile, organizations spend over $400,000 a year on average. That kind of inefficiency adds up quickly.
The challenge goes deeper than shelfware. Decentralized workspaces, new AI-bundled pricing, and limited admin controls create real risks. Unused accounts linger. Overlapping subscriptions spread. Visibility fades.
Traditional tools, spreadsheets, and manual processes can’t keep up. You need clear usage data, automated deprovisioning, and scalable license workflows to stay ahead.
In this blog, I’ll outline how Slack licensing works, where organizations struggle, and what it takes to manage Slack cost-effectively at scale. Whether you’re in IT, SAM, or Procurement, the tactics shared here can help you reduce waste, limit risk, and get more from your Slack investment.
Slack license management is the process of tracking and optimizing Slack user seats to reduce cost, eliminate waste, and limit risk. At scale, this includes:
Managing Slack licenses is more complicated than many teams expect—especially in large or decentralized environments. While Slack offers Fair Billing credits for deactivated users, those savings only apply if the right actions are taken manually and on time.
Miss a step, and you’re still paying for unused seats.
Organizations using Enterprise+ face additional complexity: users may belong to multiple workspaces, licenses may be over-assigned, and controls are often fragmented across admins. Guest users, Slack Connect, and bundled AI features only add to the challenge.
Slack license management is an opportunity for IT, SAM, and Procurement teams to drive cost savings, enforce governance, and create a more scalable way to manage collaboration tools.
Understanding Slack’s structure is essential to managing cost and complexity. Here’s how the licensing model breaks down, and where I see hidden challenges often emerge.
Slack offers four core plans, each with increasing functionality and cost:
Each plan adds more robust features, but every active user must be on the same tier. That’s why unmanaged seats or underused features quickly drive up costs.
As of August 1, 2025, Slack introduced this new tier structure that includes updated names (e.g., Enterprise+), bundled AI and Salesforce functionality, and higher pricing at the top tiers. Previously optional features—like AI summaries, advanced analytics, and Salesforce workflow automation—are now embedded in Business+ and Enterprise+ plans, raising the stakes for license utilization and oversight.
With Slack’s new plan structure, premium features are no longer offered a la carte. Now, they are bundled into Enterprise+ or Business+. These include:
These capabilities offer high value—if adopted and tracked. Otherwise, they add unnecessary cost.
Plan pricing starts low, but scales fast. Here’s a general breakdown:
For now, AI capabilities are bundled into user licenses. Because Salesforce is already using consumption pricing with Einstein and AI agents, I would expect that to pass down to Slack in the future.
For larger companies, negotiating and tracking these variables at renewal is essential to avoiding unexpected increases.
Slack’s Fair Billing policy provides credits for unused time when users are manually deactivated. This policy applies to Pro, Business+, and Enterprise+ plans. However, credits are only issued from the deactivation date forward; there’s no retroactive refund for idle accounts .
Timely deactivation is therefore essential to avoid paying for unused licenses.
Slack’s flexibility with access introduces additional considerations:
Each of these features brings value but requires oversight to manage costs and security effectively.
Enterprise+ is Slack’s solution for large organizations. It centralizes billing, compliance, and security controls. But license visibility isn’t always unified. Users can exist in multiple workspaces, and guest access can span environments. Without clear governance, license duplication and unmanaged access become costly.
Managing Slack licenses goes beyond just toggling users on and off. It can be challenging because:
These issues show up fast in my work with enterprise teams, especially those using Enterprise+. Slack often grows without structure—making it hard to maintain control once scale sets in.
In large organizations, multiple workspaces are common and are often siloed across the business. Each workspace may have its own sets of policies and admins, leading to fragmented visibility and oversight. In addition, one user might appear in multiple workspaces.
Without unified oversight, it’s difficult to reconcile these accounts or prevent them from duplicating in the first place.
Slack continues to layer in new features, especially AI. These tools can be valuable, but only if teams actually use them. And from what I’ve seen, usage varies widely.
Despite that, every user is charged the same. Without clear insight into adoption, teams often struggle to determine whether these features are worth the added cost—or if there’s an opportunity to downgrade.
Orphaned accounts are more common than most teams realize. Someone leaves the company, but their Slack license stays active. Or maybe a user hasn’t logged in for months, but no one notices.
IT teams have cut license waste spend just by identifying and removing these idle accounts. But it doesn’t happen without process. And most organizations are still relying on spreadsheets or infrequent audits.
Optimizing Slack licenses starts with visibility and ends with automation. In my experience, the most effective teams follow these practices:
These steps form the foundation of ongoing license management. They help reduce cost, support compliance, and make optimization a repeatable part of your SaaS operations—not just an annual cleanup.
Start by identifying users who haven’t logged in within the past 28 days. This is Slack’s common threshold for inactivity—and often a red flag for shelfware. However, depending on your business, I’ve seen companies choose a threshold of 60 or even 90 days of inactivity.
Organizations that review this metric quarterly often uncover hundreds or thousands of dollars in unnecessary license costs. Mapping activity data to license assignment helps ensure only active users hold paid seats.
Also look for duplicate users across workspaces. In Enterprise+ environments, this happens often, and it quietly drives up license counts.
If your organization is running multiple disconnected Slack workspaces, consolidating them under Enterprise+ can help. It brings unified billing and admin controls under one roof, making it easier to manage access, enforce policies, and optimize spend.
However, consolidation needs more than just technical configuration. It also requires clear governance. I always recommend setting policies for workspace creation, user provisioning, and shared channel management.
Not everyone needs a full license. Slack allows guest users—single- or multi-channel—who can be added without consuming a full paid seat. These are ideal for contractors, external partners, or temporary collaborators.
Used strategically, guest access can reduce your total license count while maintaining collaboration flexibility. Just be sure to review these guest accounts regularly. It’s easy to forget they exist—and they can still pose risk if unmanaged.
Manual license management doesn’t scale. Automating provisioning and offboarding through Slack’s SCIM integration—or a SaaS Management Platform—ensures users get the right access when they join and lose access when they leave.
At Zylo, we’ve seen IT drastically cut license waste by setting up automated workflows. Not only did they save money—they also improved security by eliminating access gaps.
When Slack licenses go unmanaged, three things happen consistently:
These issues don’t surface all at once—but they build fast.
Slack licenses aren’t cheap. At an average annual spend of $407k per organization, even a 10% waste rate translates into significant budget loss. In some cases, up to 48% of Slack licenses are unused.
This shelfware is easy to miss without a consistent audit process. Over time, these idle accounts continue to drain your budget—month after month—with no value delivered.
When employees leave the company and their Slack accounts aren’t properly deactivated, they become security liabilities. These orphaned accounts may still have access to shared channels, direct messages, and integrations with other tools.
Without proactive offboarding, companies expose themselves to unnecessary risk—especially in regulated industries or high-compliance environments.
License data is one of the most powerful tools you can bring to renewal negotiations. Without it, you lose leverage.
If usage trends aren’t tracked, teams often renew at last year’s license volume—or higher—regardless of actual need. That leads to inflated contracts and missed chances to optimize pricing, remove unused features, or renegotiate terms.
Proactive Slack license management keeps your team ahead of the contract cycle. It gives IT, SAM, and Procurement the confidence and data they need to make smarter decisions.
Zylo gives IT, SAM, and Procurement teams the data, automation, and control needed to reduce waste, limit risk, and optimize Slack at scale. It’s built to handle the complexity of Slack’s licensing—especially in large or multi-workspace environments.
Here’s how Zylo simplifies Slack license management:
Zylo connects directly to Slack, pulling in detailed usage data across all workspaces. This means you can see who’s active, who’s inactive, and where duplicate users exist—all from one centralized view.
No more chasing admins for spreadsheets or waiting for manual reports. With real-time visibility, you can act faster and more confidently.
Zylo automates license reclamation workflows using custom rules based on usage. If a user hasn’t logged in for 30+ days, you can notify them and ask to reclaim their license—no manual tracking required.
This reduces the risk of orphaned accounts, improves audit readiness, and helps teams maintain lean license inventories.
Zylo’s Offboarding Insight identifies Slack users who retain access after leaving the company. It integrates with HR and identity systems to flag offboarding gaps automatically—helping IT and SAM teams eliminate security risk and reclaim unused licenses fast.
With built-in Slack benchmarks and trend analysis, Zylo helps you prepare for renewals with usage data in hand. You’ll know how many licenses you actually need, where to cut, and what’s driving up costs.
These insights support better negotiations and ensure license volumes align with real usage—not guesswork.
Slack is one of many collaboration tools in a typical environment. Zylo gives you full visibility into how Slack fits into your broader SaaS ecosystem—highlighting redundancy, overlap, and opportunities to rationalize.
Managing Slack licenses in isolation won’t solve the bigger problem. Zylo brings it all into focus.
Slack drives collaboration—but without active license management, it also drives waste. With nearly half of licenses sitting unused across organizations, unmanaged Slack environments create real financial and operational risk.
Now’s the time to move from manual cleanup to proactive optimization. That means understanding usage, automating workflows, and preparing for renewals with data.
The result? Lower costs, reduced risk, and a stronger position in every vendor conversation.

Slack license management means tracking and optimizing user seats to reduce cost, remove unused accounts, and improve control. It involves assigning licenses, identifying inactivity, and automating provisioning and offboarding.
Slack provides credits for deactivated users on paid plans. Credits start from the deactivation date and aren’t applied retroactively. You must manually remove users to receive the credit.
No. All active users in a Slack organization must be on the same plan. You can’t mix Free, Pro, Business+, or Enterprise licenses within a single workspace.
All users in a workspace must be on the same plan.
Deactivation removes a user’s access but keeps their history and channel presence. Deletion removes the user entirely. Deactivation is preferred for license cleanup and Fair Billing credit.
Check for users inactive for 28+ days. Slack’s admin tools show limited data; most teams use automated tools (like Zylo’s SaaS Management Platform) to flag inactivity and remove or reassign licenses efficiently.
Slack AI is included in multiple plan tiers and is priced by license, not consumption. As you go up in tier, AI capabilities become more robust, with premium features such as AI-powered workflows, enterprise search, and AI agents.
Slack supports SCIM for automation. For broader control, SaaS Management Platforms offer advanced workflows based on role, activity, or lifecycle triggers.
