Agency pricing is rarely just a per-channel bill. Seats, connected accounts, client groups, and workspaces are different units. This study compares public monthly list prices and capacity fields for agency-shaped plans. Research notes: 15 September 2026. Re-open every source before publish. Scenarios below are planning inputs, not observed customer behaviour.

Why agency seat maths differs
Keep these units separate. Never treat them as interchangeable.
| Unit | What it usually means | Not the same as |
|---|---|---|
| Account / profile / channel | A connected social destination | A human login |
| Seat / member / user | A person who can log in and work | A client container |
| Client group | A way to organise client work (Posterly notes) | A workspace or brand |
| Workspace | A container used by some vendors (PostEverywhere notes) | Automatically equal to a client group |
Rule: a seat is not a connected social account. A group is not a workspace. If a vendor does not disclose a field, write not stated or verify. Never infer unlimited capacity.
Methodology
Three explicit planning scenarios (assumptions, not averages):
- Solo operator: 5 accounts, 1 working user, 3 client groups as a planning input.
- Small team: 20 accounts, 3 working users, 5 client groups.
- Growing agency: 50 accounts, 5 working users, 10 client groups.
Rules:
- Public monthly list prices from the research snapshot, not negotiated enterprise deals.
- Show the lowest researched tier that appears to accommodate each scenario; every row verify-before-publish.
- Mark MCP/API as included, add-on, or verify. Do not invent a competitor fee.
- SociaHive is automation-led category context, not an identical scheduler.
- This measures plan capacity and price, not approval speed, service quality, reliability, or agency profitability.
- No Autopilot, set-and-forget, ARR, traffic, rankings, or invented agency results.
Verify-before-publish: confirm Posterly Agency $49, 100 accounts, 10 seats, 30 client groups, and +$29 MCP; PostEverywhere Scale $39, 20 accounts, five members, five workspaces, included MCP; SociaHive Agency $349 and 50 accounts; Buffer Team $10 per channel; recalculate fits and gaps.

Capacity snapshot
| Vendor | Published capacity (notes) | Not established by the snapshot |
|---|---|---|
| Posterly | 100 accounts, 10 seats, 30 client groups on Agency | Exact relationship between group, seat, and approval workflow |
| PostEverywhere | 20 accounts, 5 members, 5 workspaces on Scale | Client-group equivalent and distribution by workspace |
| SociaHive | 50 accounts on Agency in notes | Seat, workspace, and automation-credit allocation |
Safe quote (verify before publishing): In a dated September 2026 snapshot, Posterly Agency was recorded at $49 for 100 accounts, 10 seats, and 30 client groups. Those units are not directly interchangeable with PostEverywhere's five workspaces.
Five, twenty, and fifty account calculations
Solo (5 accounts, 1 user, 3 groups): Posterly Starter $7 (or $10 with MCP) can cover accounts if seats and groups are not required. Posterly Agency $49 overshoots on price but clears capacity. PostEverywhere Growth $29 or Scale $39 both fit accounts. Buffer Team is $50 at five channels.
Small team (20 accounts, 3 users, 5 groups): Posterly Agency $49 fits accounts, seats, and groups in the notes. PostEverywhere Scale fits accounts and members at the 20-account cap; client-group equivalence is not stated. Posterly Power's 30 accounts fit the account count, but seat and group fields need verify. Buffer Team at twenty channels would be $200 if that channel count is valid (verify workflow fit).
Growing agency (50 accounts, 5 users, 10 groups): Posterly Agency (100 accounts, 10 seats, 30 groups) fits the recorded fields. PostEverywhere Scale does not fit 50 accounts. SociaHive Agency fits 50 accounts on price/capacity notes but is automation-led. Power's 30-account cap does not meet this scenario.
Included versus add-on MCP
| Vendor | Agency-shaped MCP treatment (notes) |
|---|---|
| Posterly Agency | +$29 add-on (all-in $78) |
| Posterly Power | +$5 add-on |
| PostEverywhere Scale | Included in researched notes |
| SociaHive Agency | 40+ tools claimed; entitlement verify |
| Buffer Team | Agent / MCP entitlement verify |

Trade-offs beyond price
Price alone cannot show whether an agency has enough people, client containers, or connected accounts. Also check platform coverage (platform breadth study), approvals, post caps, and whether the product is scheduler-led or automation-led. Product pages: PostEverywhere vs Posterly, SociaHive vs Posterly, Buffer vs Posterly.
