In one line

Long-running and retained workflows keep accruing per-day charges after the work stops.

What gets missed

Retention is a meter. A completed execution keeps billing workflow-days for as long as you retain its history, so a long retention window on a high-volume workflow can cost more than running it did.

Bills the same way

These services turn exactly the same meters, so what you learn here transfers.
