By default, the subscription renews automatically at the end of each period with the same billing frequency and quantities.
A scheduled cancellation shows its effective date. The subscription remains active until that date, then changes to Cancelled.

PDF invoices are available in the Hyperline portal, which you can open by clicking Manage subscription. See the dedicated portal article.
Changes to quantities (licenses or phone numbers) or billing frequency during a billing period are prorated. The exact amount of the next invoice appears in the Hyperline portal.
Hyperline handles automatic payments and payment reminders. A failed payment blocks access to Ubic until it is resolved.
