Why the month-end close slips, and what actually fixes it

When a close runs late, attention goes to the last step — the pack, the review, the sign-off. That is where the delay is visible and it is almost never where the delay is created.

Trace it back and the constraint is usually two weeks earlier: bank reconciliations that were not done daily, supplier invoices sitting unposted, intercompany balances that do not agree, or a stock figure nobody trusts.

Data arriving late. Nothing downstream can be faster than its inputs, and inputs are usually a process problem rather than a systems one.

Reconciliations left to month end. A reconciliation performed weekly takes minutes; the same reconciliation performed monthly takes a day and finds more.

Review as a bottleneck. One person reviewing everything serially will always be the constraint once the first two are fixed.

Move reconciliations earlier and make them continuous. This single change accounts for most of the improvement we see, and it costs nothing in software.

Automate only the rules-based steps. Judgement should stay with people; re-keying should not exist.

Then shorten the cycle a few days at a time, holding a clean close at each step. A close that goes from three weeks to three days in one attempt tends to go back.
