Pricing and no-inference rules
The captured GBP prices show Free at £0 free forever, Pro at £7 per user/month when paying monthly or £5.75 when paying annually, and Business+ at £14.40 when paying monthly or £12 when paying annually. Pro and Business+ cards display a 50% off for three months introductory offer with discounted £3.50 and £7.20 monthly figures.
Free limits message history to 90 saved and searchable days and caps the Slack App Directory at ten apps, with 1:1 huddles and 1:1 external messages through Slack Connect. Pro removes both caps and adds group huddles plus group external messages with up to 250 organisations. Business+ is flagged Best value and positions Slack AI-powered work scaling on top of the same unlimited history and integrations.
Fair billing counts a member as active for billing when they take an action in any 28-day period, and prorated credits are added for paid members who become inactive. AI features displayed across the page include conversation summaries, the Slackbot personal AI agent, AI workflow generation, AI search, AI daily recaps, and AI file summaries.
Enterprise tier prices, per-plan attribution of the shared security feature strip, exact AI credit metering, GBP prices beyond the captured en-GB state, taxes, and nonpublic discounts are not inferred.
