About Slack Technologies
Slack Technologies is the company behind Slack, a cloud-based team collaboration and messaging platform used by businesses, nonprofits, and educational institutions worldwide. The service provides organized channels for communication, direct messaging, file sharing, integrations with other workplace tools, and features like audio/video huddles and workflow automations. Slack is typically used via desktop and mobile apps or a web browser and is sold primarily on a subscription (SaaS) basis.
A charge from “SLACK TECHNOLOGIES” on your card statement usually corresponds to a paid Slack workspace subscription, such as the Pro, Business+, or Enterprise plan, or to add-ons like additional users or upgraded features. The amount often reflects the number of active members in your workspace and the billing frequency (monthly or annual). Charges may also appear after a free trial converts to a paid plan, or when an existing plan renews automatically at the end of the billing period.
If you don’t recognize a Slack charge, first log in to Slack using email addresses you commonly use, then go to your workspace’s billing page (Workspace Name → Settings & administration → Billing) to review invoices, billing history, and the card on file. Workspace Owners and Admins can adjust plans, change the billing contact, or cancel paid subscriptions from that page. For unresolved questions or suspected unauthorized use, gather the charge details (date, amount, last 4 digits of the card) and contact Slack support via their Help Center, and if necessary, notify your card issuer to dispute unfamiliar transactions.
