Billing

Last updated: 29 May 2026

Free tier

SemaFore’s free tier supports up to 5 approved members per organisation.

The free tier includes:

  • private messaging
  • group messaging
  • broadcasts
  • file transfer
  • audit logs

Professional trial

From the portal Billing section, an organisation administrator can start a 30-day free trial of the Professional plan.

Professional plan

The Professional plan is priced at GBP 9 per seat per month and supports organisations with up to 25 members.

Billing is processed through Stripe. Payment details are handled by Stripe rather than stored inside SemaFore.

At the member limit

When you attempt to approve a member that would take the organisation beyond the current plan limit, the portal displays an upgrade prompt.

Billing management

Billing is currently managed through the portal for plan visibility and trial start. If you need support with a paid plan, contact hello@attomus.com.
