Why does Bookkeeping and Monthly Close matter?
This is the least interesting discipline in a startup and one of the highest-leverage, because everything later depends on it. Diligence, a bank facility, a tax filing, and an acquisition all read the same books, and books assembled hastily from a shoebox at year end are both wrong and visibly so. The cost of doing it properly is a few hours a month and a bookkeeper; the cost of not doing it is a diligence process where every number is questioned, which is how a deal slows down and how a buyer starts looking for what else was not maintained.
What does Bookkeeping and Monthly Close look like in practice?
Suppose a company closes each month within ten days: bank reconciled, invoices recorded in the month the service was delivered rather than the month cash arrived, expenses categorized consistently. Eighteen months later an acquirer asks for monthly figures for the whole period, and they exist. Now suppose the alternative, where categories drifted, personal and company cards mixed early on, and revenue was recorded on receipt. The same request triggers weeks of reconstruction by people who should be running the company, and the resulting numbers invite exactly the scrutiny you least want.
What are the common mistakes with Bookkeeping and Monthly Close?
- Mixing personal and company spending, which is tedious to unpick and reads badly to every professional who sees it.
- Recording revenue when cash arrives rather than when it is earned, which quietly misstates every metric built on top.
- Letting categories drift, so month-to-month comparisons compare different things.
- Treating the annual tax filing as the accounting. Filing is an output; the close is the process that makes it true.

- Cash Flow vs. ProfitProfit is what the accounting says you earned in a period. Cash flow is what actually moved in and out of the bank. A company can be profitable on paper and still run out of money.
