The books of a one-person business

The first payments have started arriving, and with them the oldest trap of the one-person business: the money that comes in and vanishes, uncounted, into the same pocket as transport and tomatoes. Six months later the work was real but the profit is a rumour. The cure is not an accountant — not yet. The cure is four small habits, all of them things you already know how to do, applied to your own money with the discipline you have been applying to other people's systems since lesson one.

Habit one: separate the money. A second account — the bank app lesson's two accounts, now with a purpose — receives every business payment and pays every business cost; personal money is transferred out like a salary, decided, not nibbled. Habit two: record every in and out, weekly, fifteen minutes — the weekly money list from lesson eighty-four, grown up: what came in, from whom; what went out, for what. A notebook works; a spreadsheet works better; the discipline works best of all. Habit three: split every payment the day it lands — set aside a slice for tax, because the government's interest in small business is maturing here too, and a slice for rain, because laptops die in the middle of jobs and clients do not extend deadlines for fun. What remains is profit you can actually spend, without owing anybody.

Habit four: reconcile, monthly

Once a month, the quiet hour: download the statement — the bank lesson showed where it lives — and sit it beside your own records. Every entry on one should sit on the other. The transfer that never landed. The subscription you meant to cancel, still drinking. The client's payment recorded twice in hope. The reconciliation is the spreadsheet lesson's when-the-cell-looks-broken, applied to life: a difference found now is a one-line fix; the same difference found in December is a mystery novel. And when the year closes, the books answer the questions that decide next year with numbers instead of vibes: which work actually paid, which clients actually pay, what the business costs to run before a single naira of profit.

The tools, honestly: begin with notebook or spreadsheet — you own both skills already. When volume justifies it, a small bookkeeping app or a part-time accountant earns their fee, and the books you kept make hiring them a week's work instead of an archaeology. What no tool supplies is the habit; and no investor, no loan officer, no visa officer, no big client will ever take your business more seriously than your books do. The shop that keeps books is a business. The one that does not is a habit.

• Open the second account this week, even if the first payment has not arrived. Build the wall before the water.
• Book the weekly fifteen minutes in the calendar — in and out, every week, no exceptions, no heroics.
• Split on arrival: tax slice, rain slice, then spend. The percentages are yours; the order is not negotiable.
• Reconcile on the first Saturday of the month. Statement against records, line by line, until they agree.

The books are the business's own portrait

One reframe to close: the books are not bureaucracy. They are the honest mirror the bank lesson taught you to read for your employer's sake — read now for your own. The weekly list, the split on arrival, the monthly hour: together they turn a person who earns into a business that lasts, and they answer, at last, the question every worker on this shelf deserves to ask precisely: is this working? Now you will know, to the naira.
