Remove former staff and vendors from billing portals while preserving invoice, approval, and audit records. 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 user name, portal, role, legal entity, last login, open assignments, export owner, disable request, approver, disable confirmation, and follow-up date. 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.
