For a media payment reconciliation, the practical backend cron alternatives for scheduled scripts are a timer, a queue-backed worker, or an HTTP task boundary. The cheapest-looking timer is not automatically the cheapest system: the real decision is how much latency you can tolerate before the media business sees a discrepancy, and how much operational machinery you are willing to own.

The useful boundary is this: use a simple scheduler when one run can be retried safely; use a queue-backed design when work can outlive the scheduler; use a workflow tool only when the human and application steps justify its extra abstraction. That rule keeps a 02:00 reconciliation from turning into a daytime accounting incident.

Start with the deadline.
