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.
