The accounting cycle, and why the order is not negotiable

Bookkeeping looks like an unbounded set of chores. It is not. It is one loop, repeated, and every task belongs somewhere in it.

The loop#

1. Something happens. A sale, a purchase, a payment, a payroll run. The event, not the paperwork, is what the books are recording.

2. It gets a source document. An invoice, a bill, a receipt, a bank line. This is the evidence, and everything downstream inherits its quality. No document, no defensible entry.

3. It becomes a journal entry. Debits and credits that balance. In modern systems you rarely write one by hand — raising an invoice writes it for you — but the entry exists whether or not you saw it.

4. It posts to the ledger. The entry lands in accounts, and account balances move. This is the step where a transaction stops being an event and becomes part of the position.

5. The trial balance proves the mechanics. Total debits equal total credits. This proves the arithmetic, and nothing else — a transaction posted to entirely the wrong account still balances perfectly. It is a necessary check, not a sufficient one.

6. Adjustments go in. Accruals, prepayments, depreciation, inventory movements. This is where a cash-shaped ledger becomes an accrual one, and where judgement enters.

7. Statements come out. Profit and loss for the period, balance sheet at the end of it, derived from the posted entries rather than maintained separately.

8. The period closes. Locked. Corrections after this point are new entries, not edits.

Then it starts again.

Where the loop usually breaks#

Three places, consistently.

Between 1 and 2 — the event happened, the document never arrived. The supplier invoice sitting in someone's inbox, the expense claim in a coat pocket. Nothing downstream can compensate, because the ledger does not know the transaction exists.

Between 5 and 6 — the trial balance is treated as the finish line. It balances, so the books must be right. But a balanced trial balance with rent posted to travel produces a perfectly balanced, entirely wrong P&L.

At 8 — the period never actually closes. It stays open, gets edited, and the statements you circulated in April quietly become different numbers in July.

Why derived beats stored#

Step 7 says statements are derived from posted entries. That is worth being literal about.

If a report reads a stored balance somewhere, that balance can drift from the transactions that produced it — and when it does, there is no way to tell which one is right. If every figure is computed from the journal lines each time it is asked for, drift is impossible by construction. Slower, and worth it.

The same principle is why a correction has to be a new entry rather than an edit. Editing a posted transaction changes what the statements said without leaving any record that they changed. The immutable ledger post covers what that costs and why it is worth paying.

The cycle is what you hand over#

The practical value of thinking in a loop is that it makes the work transferable. "Do the bookkeeping" is not a set of instructions. "Every Tuesday, steps 1 to 4 for last week; at month end, steps 5 to 8 in this order, with these reconciliations" is.

That written-down loop is the single most useful document in a small company's finance function, and the one that almost never exists — which is exactly why a handover usually means a month of archaeology.

The close sequence is steps 5 through 8 in detail, and the free handover template is the list of everything a successor needs before they can run any of it.
