About Slack

Slack is a business communication and collaboration platform that organizes work into channels for teams, projects, and topics. Based in San Francisco, CA, Slack (a Salesforce company) provides real-time messaging, searchable conversation history, file sharing, voice and video huddles, and integrations with thousands of workplace tools like Google Workspace, Microsoft 365, Zoom, and more. Slack offers a free plan with limited history and features, as well as paid tiers such as Pro, Business+, and Enterprise Grid designed for larger or more regulated organizations.

A Slack-related charge may appear on your bank or card statement if you (or your company) upgraded a Slack workspace from the free plan to a paid plan, added more members to a paid workspace, or renewed an existing subscription. Common descriptors include terms like “SLACK”, “SLACK TECHNOLOGIES”, “SLACK*SUBSCRIPTION”, or similar. Charges are typically billed per active member, either monthly or annually, and may include prorated amounts when users are added or removed mid-cycle. You may also see a temporary authorization hold when you first add or update a payment method, or a charge following the end of a free trial of a paid plan.

To verify a Slack charge, sign in at slack.com, open the workspace you use for work or community groups, and have a billing owner or admin visit Settings & administration → Billing to review invoices, payment history, and upcoming charges. If you do not recognize the workspace, check with your employer or organization, as many Slack subscriptions are company-managed. For help, a workspace billing owner can contact Slack Support via help.slack.com or through the in-product “Contact support” option; Enterprise Grid customers typically work directly with their Slack account team. If you suspect unauthorized use of your card, first check for any Slack accounts tied to your email addresses, then contact Slack Support and your bank/card issuer as needed.

Frequently Asked Questions

What types of Slack subscriptions could be causing this charge?

Slack offers several plans: a Free plan (no recurring charges), the Pro plan (typically around $8.75 USD per active user/month when billed annually or $10 USD when billed monthly), Business+ (around $15 USD per active user/month annually or $18 monthly), and Enterprise Grid with contract-based pricing. The charge you see is usually for a Pro, Business+, or Enterprise Grid workspace subscription, based on the number of billable members and your chosen billing frequency (monthly or annual). Exact pricing and currency can vary by region and contract.

Why was I charged by Slack when I thought my workspace was on the free plan?

A Slack workspace can move from the Free plan to a paid plan if a workspace owner or admin upgrades it, starts a paid trial that converts automatically, or accepts a quote or invoice for Enterprise Grid. If you see a charge, a billing owner may have upgraded the workspace or added a payment method in the past. Have a workspace owner go to Settings & administration → Billing on slack.com to confirm the current plan and recent billing activity.

Why did my Slack charge amount change this month?

Slack bills based on the number of billable members in your workspace and may include prorated adjustments. If members were added, removed, or deactivated, or if you changed plans (for example from Pro to Business+), your invoice can increase or decrease accordingly. In the Billing section of your workspace, you can download detailed invoices that break down user counts, prorations, taxes, and credits for each billing period.

How do I cancel or downgrade my Slack paid subscription to stop future charges?

Only a workspace owner or billing owner can change your plan. From a web browser, open your Slack workspace, then go to Settings & administration → Billing → Overview and choose the option to change plan, downgrade to the Free plan, or schedule cancellation at the end of the term. If you’re on an Enterprise Grid plan or a custom contract, contact your Slack account representative or Slack Support to discuss termination or changes; contract terms may specify a minimum commitment period.

How do I request a refund or credit for a Slack charge I didn’t expect?

Slack’s standard policy does not provide automatic refunds for partial billing periods, but in some cases they may issue credits (for example, for overbilling due to a technical issue or rapid user removals). A billing owner should sign in to slack.com, go to Settings & administration → Billing, review the invoice in question, and then contact Slack Support from help.slack.com or from the in-app help menu to explain the situation. For Enterprise Grid or contract customers, reach out directly to your Slack Customer Success or account team with your invoice number and details. If you suspect fraud, notify both Slack Support and your bank or card issuer promptly.

Why do I see a small or temporary Slack charge (like $0–$2) on my statement?

Slack may place a small authorization hold when you first add or update a payment card to verify that the card is valid. This is not a completed charge and is usually reversed or disappears from your statement within a few business days. If a real subscription payment is due around the same time, you might see both an authorization and a separate full subscription charge.

How can I confirm which Slack workspace or account is associated with this charge?

The charge is tied to a specific workspace, not to an individual user account alone. A billing owner can sign in at slack.com, click your workspace name → Settings & administration → Billing, and check the workspace name, URL (e.g., yourteam.slack.com), and invoices listed there. If you manage multiple workspaces or companies, cross-check each workspace’s Billing page and the invoice dates with the date of the charge on your statement.

How can I contact Slack about a billing or charge issue if I’m the cardholder but not a workspace admin?

If possible, first contact the workspace owner or your company’s IT/finance team, as Slack can share detailed billing information only with authorized workspace or organization admins. If you still need help, you can visit help.slack.com and use the support contact form, providing the last 4 digits of the card, charge date, amount, and any descriptor text from your statement; Slack may need confirmation from an authorized admin before making account changes. For Enterprise Grid customers, your internal admin or procurement team should reach out to your assigned Slack account representative on your behalf.
