The tier base + metered events the platform charges for, the metered-only org billing mode, and how the period rolls up into an invoice draft. Numbers live on /pricing.
Tiers & metering
Tier base
Every paid tier carries a flat monthly base. The tier you
bought at checkout (Solo, Pro, Team, Enterprise, or Fleet)
sets the base; changing tier changes the base from the next
billing period. See /pricing for the tier
matrix and the per-tier base price.
Metered events
In addition to the tier base, the platform charges per-event for specific operations. The kinds you can see on your statement today:
- Job transitions — every FSM transition fired against one of your workflow jobs.
- Outbound webhooks — every successful delivery of a webhook subscription you configured.
- Email egress — every outbound platform email (notifications, mention emails, alerts).
- Extension bundle bytes — bandwidth served from your installed extensions, bucketed by byte count.
Per-event rates live on /pricing. Rates live on
/pricing, not in docs — anything we wrote here would drift
the moment marketing tunes a number.
The metered-only billing mode
An organization can be switched to a metered-only mode by the platform team. In that mode:
- The tier base is zeroed for billing purposes — you pay only for metered usage.
- The org is exempt from the prepaid-wallet auto-suspend (see Wallet & top-ups) because billing is reconciled out-of-band.
- The current-period draft on Settings → Billing & usage is stamped accordingly so the breakdown shows usage-only.
Metered-only is a per-org configuration handled by the platform team — there is no self-serve toggle in product today.
Invoice drafts
At any moment during a billing period the platform maintains a draft of what your invoice will look like at period end. The draft rolls up the tier base and every metered event attributable to the period. You can see the current draft on Settings → Billing & usage; the finalized invoice is delivered through the Stripe Customer Portal at period close.
What's not in metering today
- Per-tenant usage caps — set a hard ceiling on metered events for a tenant.
- Custom metered events — meter a custom action defined in your workflow.
- Real-time spend dashboards — what's on Settings → Billing & usage updates on a cadence, not in real time.
