Connect an accrual estimate to its reversal, actual invoice, variance explanation, and final review. The working definition should name the covered entities, accounts, period, source systems, cutoff, preparer, reviewer, and the event that closes a row. A queue is useful only when another person can tell what is ready, what is waiting, and what decision remains protected.
For this workflow, record accrual ID, service period, vendor, estimate basis, amount, account, reversal journal, actual invoice, variance, explanation owner, and reviewer status. Use stable identifiers from the governing systems. Free-text notes may explain an exception, but they should not replace the transaction ID, source date, amount, status, or evidence location that lets the reviewer reproduce the result.
