In plain words
Many small traders keep no proper books: a bank statement, a pile of invoices and a notebook. The profit can still be found. It takes detective work, and two ideas do most of it.
6 things to know
- A small business may not keep full double entry records because it saves time and money, and the owner may not know how. The drawbacks: errors and theft are harder to notice, and there is less information for running the business or for getting a loan.
- A statement of affairs lists the assets and liabilities at a date. Capital = assets − liabilities.
- Profit can be found from the change in capital: profit = closing capital − opening capital + drawings − capital introduced.
- Credit sales = money received from customers + closing trade receivables − opening trade receivables. Add any discount allowed, irrecoverable debts and sales returns.
- Credit purchases = money paid to suppliers + closing trade payables − opening trade payables. Add any discount received and purchases returns.
- With sales and purchases found, the statement of profit or loss and the statement of financial position are prepared in the usual way, with the usual adjustments.
Worked example
A trader's assets were $30 000 and liabilities $8000 at the start of the year. At the end, assets were $41 000 and liabilities $9500. During the year he took drawings of $12 000 and paid in extra capital of $3000. Calculate the profit for the year.
- Opening capital = 30 000 − 8000 = $22 000.
- Closing capital = 41 000 − 9500 = $31 500.
- Profit = 31 500 − 22 000 + 12 000 − 3000 = $18 500.
Tips and tricks
- Drawings are added back because they reduced the closing capital without being a loss. Capital introduced is deducted because it increased the capital without being profit.
- To find credit sales, think of the customers' accounts as one account and look for the missing figure. A quick sketch of that account avoids sign errors.
