Who can change billing
Only the workspace Owner, on Settings → Billing.
Upgrade
Choosing a higher plan starts WayForPay checkout or a plan change. Access to the new limits is intended to apply immediately after payment confirms.
Downgrade
WayForPay may bill the cheaper price from the next period, but Duvento applies the target plan’s limits in the workspace immediately. Export or reduce records before you drop to a smaller cap — you do not keep the old limits until the billing date.
Cancel
Cancel at period end keeps the paid plan until the date shown, with a Resume action while it is still scheduled. Cancel immediately ends paid access now. When cancellation takes effect the workspace is moved to the internal trial/expired state and becomes read-only; it is not a free Cloud tier and is not converted into a self-hosted install. Subscribe again from Billing, or export CSV and install self-hosted separately.
