The close is the chain most often produced as evidence that a system acts, and it is the narrowest one here: it moves money and information and very little else. It is first so the other seven can be read against it.
The last subledger for the period stops accepting postings and the close calendar opens on day one, with the prior day's bank statements and the final goods receipts already in.
Reconciles every bank account to the cash ledger at statement line level, clearing what matches and listing what does not by age, value and account, never as a single difference.
Accrues for goods received and not yet invoiced by pairing open goods receipts against purchase order prices, and reverses the prior period's accrual first so the same cost cannot be carried twice.
Runs depreciation and amortisation across the fixed asset register, including assets capitalised mid period, which are depreciated from their in service date, not from the period start.
Revalues foreign currency monetary balances at the period end rate and posts the unrealised movement to the revaluation account, leaving non monetary balances at historic rate.
Matches intercompany balances pair by pair, eliminates what agrees on both sides and lists what does not with the counterparty entity, the amount and the age of the difference.
The controller dispositions one accrual the system cannot settle, on a contract in dispute where the amount owed turns on whether a delivery obligation was met. The reading of the obligation is the input the ledger does not hold.
Runs the variance review at account level against prior period and budget, holding every account whose movement exceeds the stated threshold until the movement is attributed to transactions it can name.
Posts the entries that fall inside its grant, each carrying the evidence it was built from, the version of the policy in force and the accounts it was read from.
The controller signs the close, which is the point at which responsibility for the reported position passes to a person who can answer for it.
Files the close package, locks the period against further posting, and records the trial balance, the entry list and the open reconciling items as the record of what the period was closed on.
An entry above the value ceiling in the grant, an intercompany difference that survives matching, a bank item unreconciled beyond the stated age, or an account whose variance the system cannot attribute to transactions it can name.
A closed period: journals posted to the ledger, the period locked, and a trial balance signed by a named person, with every entry reconstructable to the evidence and the policy version that produced it.
