Accounting month end close procedures exist for one practical reason: so the close does not depend on one person being available. Everything else, the audit comfort, the process discipline, the induction material, is secondary to that. Which makes the test for whether your procedures are good enough refreshingly concrete: could a competent person who does not work here run the close from them? Most documented procedures fail that test, not because they are short but because they record the steps and omit the knowledge, which lives in the head of whoever wrote them. This page is what to write down so that they pass it.
Document the judgements, not just the steps
Posting an accrual is a step and anyone can do it. Knowing which costs are routinely accrued, who to ask for the estimate and what the usual size is, is the knowledge that makes the step possible. That is what to write down.
Name the people outside finance
A close depends on approvers, budget holders and whoever knows what a provision should be. A procedure that names them, and their alternates, is worth more than one that describes the accounting perfectly.
Keep the evidence with the month
Reconciliations, the aging at cut-off, the unapproved list and the sign-off, attached to the month they belong to. That turns a procedure into something a successor or an auditor can follow backwards, which is the real handover test. Retention of those records is a policy question worth deciding deliberately.
Questions people ask about accounting month end close procedures
How is this different from the checklist?
The checklist says what to do and in what order. The procedures say how, and who to ask. Most teams have the first and not the second, which is why the close survives a busy month and not a resignation.
Do procedures need to be approved by anyone?
Someone should own them, and the budget holders should have agreed anything that commits them. Formal approval is not the point; being current is.
How long should they be?
Long enough to pass the handover test and no longer. If a section is never read during a close, it is documentation for its own sake.
