Accounts · The books

One set of postings.
Every report.

The profit and loss, the balance sheet, the cash flow and the ageings are all computed from the same entries. There is no reporting database to refresh, and no version of the truth that lags the other one.

Why two reports usually disagree. Because they were built from different extracts at different times. These are not.

The statements

The three that matter, and the ones underneath.

Profit and lossFor any date range, from the postings, with the accounts that produced each line openable.
Balance sheetThe position at a date, tying to the same trial balance every other report reads.
Cash flowWhere the money actually went, as distinct from what the P&L recognised.
Trial balanceThe check underneath all of them.
The daily view

Day book, cash book, ledger.

Day bookEverything that happened on a day, in order — the view a bookkeeper actually works from.
Cash bookCash in and out, separate from the bank, because most Indian businesses genuinely run both.
Ledger per accountEvery posting to one account over a period, with its source document.
Who owes whom

Both ageings, from the same documents.

Receivables ageingWhat is owed to you, by age.
Payables ageingWhat you owe, by age — computed the same way, so the two are comparable.
