Prepaid expenses / Unearned revenue: You have paid but not received (asset), or you have been paid but you have not given or provided (liability)
Accrued revenue / expenses: Revenue not collected, or expenses not paid.
The thing is that the two first (PE-UR) show up on the balance sheet as themselves, but the others do not, right? Accounts receivable would be an Accrued revenue, but it does not appear with that specific name, whereas PE-UR do, I think.
