python
from billing import BillingEngine, Subscription
# Initialize billing engine
billing = BillingEngine()
# Create subscription
subscription = billing.create_subscription(
customer_id="cus_123",
plan_id="plan_pro_monthly",
billing_cycle_anchor=datetime.now(),
trial_days=14
)
# Process billing cycle
billing.process_billing_cycle(subscription.id)Detailed patterns and worked examples
