Month-end and year-end close

A closed month is a month that no longer changes.

You check which days are signed off, close the month, and Containn blocks new entries in that period. Reopening requires permission and records who, when and why.

How it works

Review the month’s status

Which days are signed off, how many journal entries it has, what’s missing.

Close the month

From then on, no new entry lands in that period.

Close the fiscal year

The year’s result is transferred to retained earnings.

Why it matters

The difference between accounting and a spreadsheet is that accounting has periods that close and can’t be touched again without leaving a name. Containn treats it as a signature, not a preference.

What’s included

Month status: which days are signed off, how many journal entries it has, what’s missing.
Month-end close, which blocks new entries in that period.
Reopening with permission and a record: who, when and why.
Fiscal year status and close, with the year’s result transferred to retained earnings.
Fiscal year reopening, with the same trail.

Who can reopen a closed month?

Only someone with the reopen permission, which is separate from the close permission. Every reopening is recorded with its reason.

What happens to the result when the fiscal year is closed?

It’s transferred to retained earnings.

Journal entries and general ledgerOne journal entry per signed-off day, and none that don’t balance.Financial statementsIncome statement, balance sheet and trial balance, from the general ledger.Audit and internal controlEvery peso has a name, a date and someone responsible.

Start with yesterday.

If your hotel already signs off on its night audit, Containn can post yesterday today. The chart of accounts is set up in one step, the transaction code mapping is done once, and from then on every signed-off day becomes a journal entry.
