- Priced by how many social accounts you connect: the plan steps up with the band you land in, 5, 15, 30, then 80 accounts. On Business you can add extra accounts at $1 a month each.
- Each connected destination consumes an account slot. Verify current destination eligibility, particularly Reddit and messaging-only channels, rather than treating analytics coverage as publishing support.
- There's no free plan, but a 7-day trial with nothing due upfront.
- Basic annual billing is $180 ($15 monthly equivalent). Each Google Business Profile location consumes one account slot.
- Basic holds 300 scheduled posts at once, not 300 per month. Cross-posting to three accounts consumes three waiting-post slots.
- Fair-use daily publication caps across accounts are 150/500/750/1,000 on Basic/Intermediate/Growth/Business.
- X link-post add-ons are sold in $50/month increments covering 250 link posts.
