Start with a decision register, not a number. List recurring decisions in the bookkeeping workflow, the role allowed to make each decision, the evidence required, and the latest useful response time. Then define a normal-review lane, an owner-approval lane, and an immediate escalation lane. The lanes should include examples and non-examples so a new reviewer is not forced to infer the rule from historical messages.
For example, an incomplete source document may stay in ordinary review when the period is open and no approval boundary is crossed. A payment-related item with an unclear approver should move to the owner lane even if its value is small. A payroll or filing input with a deadline risk may need immediate escalation while the bookkeeper continues assembling facts. These are illustrations of decision logic, not universal materiality thresholds.
The escalation record should preserve the original evidence, the reason the threshold was met, the owner, timestamp, response state, and any later correction. If an owner declines or changes the proposed action, that decision should be visible rather than rewritten as a preparer resolution. Aging reports should show both time outstanding and time since the last owner response; otherwise repeated reminders can look like progress.
The same record should distinguish a blocked item from an unanswered request. A blocked item lacks a prerequisite; an unanswered request has reached the person who can decide but has not received a response. That distinction helps a manager improve source availability, coverage, or delegation instead of applying pressure indiscriminately. It also gives a later reviewer enough context to understand why a deadline was missed.
