My experience is that you need to plan for retries at the system level anyway (above application; think “dead letter queue processing” or equivalent).
When you don’t (as we sometimes haven’t), you end up with people having to write scripts or perform manual actions to poorly approximate what the system should have done, often with thousands of orders (or whatever entity matters to your company) in a limbo state.
