what Slack actually costs in 2026
$7.25 per user/mo (Pro, annual) · $8.75 (monthly)
Business+ ($15/user/mo annual) is often bought for AI features a 5-50 person team barely uses; Pro covers most startup needs.
what companies your size actually pay
We have read 4 Slack invoices so far, which is fewer than the five we require before publishing a range. Until then this page shows published list pricing only, above.
the levers that work
- annual billing saves ~17% vs monthly ($7.25 vs $8.75)
- new-team promo: 50% off Pro/Business+ for 3 months if purchased within first 7 days of workspace creation
- seats auto-sync to active member count each renewal, so removing inactive users before renewal avoids paying for unused seats
Across the audits we have run, roughly 15% of a small company's Slack line is recoverable without changing provider.

A published price is not a quote. In a full audit we email the alternative as a disclosed agent for your company and get a real price for your exact usage — which is the number your incumbent actually responds to.

Drop last quarter's invoices. We name every line you are overpaying, with an annualized amount, free. The full audit is $299 once: it gets a real quote from the alternative for your exact usage and runs the renegotiation with your incumbent until there is an answer. If it does not identify at least $2,990/yr, we refund it in full.
