What is period-end closing (locking) in accounting software?
IntermediateAnswer
Period-end closing locks a completed accounting period so transactions can't be added or changed after it's finalized and reported. It preserves the integrity of reported figures; any needed adjustment to a closed period is made by a dated journal in an open period or by a controlled reopening, with the audit trail recording it.
Real-world example After filing the VAT return, the bookkeeper locks the quarter so those figures can't be altered accidentally.
