Do all IRIS services use the same payment model?
No — the payment model follows the service. The Alert Management services (SMS and Voice/IVR escalation) are sold under a hybrid model: a per-user monthly subscription with a bundled monthly credit allowance, plus buyable credit packs for overage — paid plans launch with card payments, and the free trial is available today. The SMS-sending API (one-shot direct sends, no escalation) is prepaid only: you buy credits in advance — credit packs or an invoiced credit purchase — and each sent message consumes them, with no subscription, no seat fee and no minimum term. All services draw from the same per-tenant credit balance (1 credit = €0.01).

If I use both services, do I need two credit balances?
No. Credits are fungible within your workspace: one ledger, one balance. A tenant on an Alert Management plan can call the SMS-sending API against the same balance — bundled allowance included — and a direct-send-only tenant simply never pays a subscription.
Why is the SMS-sending API not part of a subscription?
Because its usage pattern is pay-per-message: one-shot sends with no escalation, no acknowledgement tracking and no per-user workflow. Charging a seat fee for that would be a per-user tax on a service nobody logs into — so it is pure prepaid: only messages actually sent consume credits, and suppressed or rejected sends are never charged.
Which credits are spent first on an Alert Management plan?
The bundled monthly allowance is consumed before purchased credits — bundle credits expire at the end of the billing month (no rollover), while purchased credit packs stay valid for 12 months.
