Monthly period-end closing

Period locking prevents any new dated entries from being made in a given month: sales, purchases, receipts, miscellaneous transactions, reversals, allocations, provisions and settlement or direct debit campaigns. This is an optional monthly close: no month is locked by default.

What it is for

Once an accounting month has been closed and checked, we want to prevent any entries from being added or amended by mistake, as this would distort figures that have already been reported (to a manager, a bank or the tax authorities). Period locking addresses this need: by locking a month, no further transactions dated within that month can be created, regardless of their source (sales, purchases, bank transactions, manual entries, reversals, depreciation charges, provisions, or batch transfers or direct debits). This is an opt-in feature: by default, no month is locked, and you decide for yourself when to close a month. Unlocking remains possible if necessary, for example to correct an error discovered after the fact — but this then reopens the door to any new entries for that month.
