When something slips
An estimate is not a settlement
It happens. A channel export is late, a bank feed disconnects, a supplier invoice arrives after the close.
When a missing figure is material, we say so in writing and either hold the line or post it in the following period with a note. What we do not do is plug the gap with an estimate and let the two runs disagree next month. The aim is books that hold their shape over time, not a fast close that unravels.
