To use your ApprovalMax Organisation after trial expiration, you need to add it to a paid subscription.
You can do this while purchasing a subscription, or later.
Additionally, it's important to note that some features available during the trial period may not be included in certain paid plans. For example, the "Review" step available during the trial is not included in the standard subscription plan.
Please note: If you purchase a subscription/add an Organisation to a subscription after trial expiration, you'll need to manually reactivate your approval workflows.
