+Scenario: Successful invoice generation within SLA
+  Given I am a policyholder with an active policy "POL-12345"
+  And my policy was issued within the last 24 hours
+  And the billing system is operational
+  When the automated invoice generation process runs
+  Then an invoice should be created within 24 hours
+  And the invoice should include policy number and premium details
+  And the invoice should be sent to my registered email address
+  And the invoice status should be marked as "Generated"
