These Billing & Usage Terms explain how PurpleCallio measures, calculates, and charges for usage-based services.
PurpleCallio charges customers based on the services they consume according to the rates displayed on the applicable pricing page.
There are no subscription fees or up-front costs — you only pay for what you use.
Authoritative pricing
PurpleCallio uses participant-minute billing. Audio, video, and screen sharing are tracked separately. Screen sharing is billed as its own usage category and is not automatically added as a surcharge to video minutes.

For communication services billed per participant-minute, one participant using the applicable service for one minute equals one participant-minute.
For example:
This is important because the applicable per-minute rate applies per participant, not per room.
PurpleCallio may apply different rates to:
The applicable rates are displayed on the pricing page and may vary by currency, region, product, or service.
Audio, video, and screen sharing are independently tracked usage categories. Screen-sharing participant-minutes are not automatically added as a surcharge to video participant-minutes.
If a session changes communication modes during a call, PurpleCallio may calculate usage separately for the applicable periods.
For example: 10 minutes of Audio + 5 minutes of Video + 3 minutes of Screen Sharing.
Each applicable usage segment is rated according to its applicable rate.
If participants join or leave a session, usage is calculated according to the number of participants using the service during the applicable period.
Therefore, a single call can produce different participant-minute totals over its lifetime.
PurpleCallio's backend usage records are the authoritative source for billing calculations.
Customer dashboards may display estimated or current usage, but final invoices are generated from PurpleCallio's billing records.
PurpleCallio tracks usage in per-second increments.
For invoice display, usage is rounded up to the nearest minute per usage segment. Billing is calculated on the underlying per-second usage.
Every account receives a monthly free allowance of audio and video participant-minutes as shown in the current rates published by the billing service, plus unlimited projects and developers.
Screen sharing has no free allowance and is always billable. Usage beyond the free allowance is billed at the applicable rates.
PurpleCallio may provide usage notifications when customers approach configured usage or spending thresholds.
Customers are responsible for monitoring their usage.
Customers must maintain a valid payment method for paid usage.
Where supported, PurpleCallio may automatically charge the customer's payment method for billable usage.
A 18% GST applies on billable usage.
If a payment fails, PurpleCallio retries and notifies you, then enters a 7-day grace period.
During the grace period existing calls continue uninterrupted, but new calls are paused until the payment succeeds.
Customers should report suspected billing errors within 30 days of the applicable invoice.
