The short answer
A Slack workspace subscription — the workplace messaging app owned by Salesforce. Slack bills per active user (Pro is about $8.75/user/month on annual billing), so the amount moves as people join or leave. The card usually belongs to the workspace owner or billing admin, which is why a Slack charge can outlive your involvement in a team.
Decoding SLACK TECHNOLOGIES
Slack Technologies, LLC is Slack's U.S. billing entity, headquartered in San Francisco. Statement lines name the company rather than a product, so workspace plans (Pro, Business+, Enterprise Grid) and seat increases all post under the same descriptor.
The amount is the real tell: Slack bills per active user, not per seat. A $43.75 line, for example, is five active users at Pro's $8.75 annual-billing rate — and the total moves mid-cycle with prorated adjustments whenever members are added or removed. Keeping close track of your monthly statements ensures complete financial security and prevents unexpected surprises from recurring charges.
- Open the workspace billing page Sign in at slack.com, open the workspace, then Settings & administration → Billing to see the plan, seat count, and invoice history.
- Identify the workspace URL The charge is tied to a specific workspace (like yourteam.slack.com) — check every workspace you've created or administered.
- Search email for invoices Slack emails invoices from its billing system — the inbox holding them points at the workspace that's paying.
Why is my Slack charge not a round number?
Slack bills per active user, so totals are seat count times the per-user rate, plus prorated adjustments when people join or leave mid-cycle.
Is SLACK TECHNOLOGIES LLC a fraud charge?
Almost never — it's the legal billing name for Slack subscriptions. If nobody with card access has a workspace, contact Slack support and your issuer.
The workspace angle
Slack billing attaches to a workspace, not an individual login. The card on file often belongs to the workspace owner or a billing admin, while the people creating the cost are the members. Former-employee, client-team, and community workspaces are the classic sources of a 'who is this?' Slack charge.
Workspace billing also keeps running after a team stops using it — an old workspace stays paid until an owner or admin cancels or downgrades the plan. A small authorization hold ($0–$2) can also appear briefly when a card is first added or updated; it drops off on its own.
- The card belongs to the workspace owner or billing admin — members just create the cost.
- Old or inactive workspaces keep billing until an owner cancels the plan.
- Prorated amounts appear when users are added or removed mid-cycle.
- Ask coworkers or former colleagues Many Slack subscriptions are company-managed — the workspace owner may be you or an ex-teammate.
- Cancel or downgrade the plan Only workspace owners and admins can cancel: Settings & administration → Billing → Cancel plan.
- Escalate to Slack support Use help.slack.com with the charge date, amount, and last 4 digits of the card if you still can't trace it.
I see a $1-ish Slack hold on my statement. What is it?
A temporary authorization when a card is added or updated to verify it's valid. It isn't a completed charge and disappears within a few business days.
Other Slack descriptors
Some processors show SLACK alone, SLACK*SUBSCRIPTION, or SLACK T0101-style tokens with the plan code appended. EU and UK billing can show SLACK +35315137661 IE — Slack's Ireland billing line. All trace to the same Slack billing system.
Why does my Slack charge mention Salesforce?
Slack is a Salesforce company (acquired in 2021) — some newer billing runs through Salesforce Commerce Cloud, which still posts under SLACK* descriptors.
