Separating business and personal money

The first rule of small-business bookkeeping is that business money and personal money live in different places. When groceries, software subscriptions and client payments all flow through one account, every transaction has to be investigated before it can be recorded, and some will be guessed wrong. Mixed accounts also make it hard to prove which costs were genuinely for the business if a tax authority, lender or buyer ever asks. Even where the rules let sole traders use a personal account, a dedicated business account is one of the cheapest time-savers available.

Separating money takes four steps. First, open a business current account; if your business is a separate legal entity, such as a company, the account must be in the business’s own name. Second, get a card linked only to that account and use it for every business purchase. Third, move all customer payments to the new account details on the same day: update your invoice template, payment links, card terminal and marketplace payout settings. Fourth, choose a cut-over date after which nothing personal touches the business account, and note it in your books as the start of clean records.

Once the money is separated, you need a clean way to move it between the two worlds. In an unincorporated business, money you take for yourself is usually called drawings; in a company it may be salary, dividends or a loan from the company, each treated differently for tax depending on your country. Whatever the form, make transfers deliberate. One or two fixed transfers a month with a clear description are far easier to follow than dozens of small withdrawals. If you pay a business cost personally by accident, record it and reimburse yourself with a single, labelled transfer.

Three habits commonly undo the separation. The first is the “just this once” purchase: a personal item on the business card because the other card was at home. The second is leaving old payment details active, so a few customers keep paying into your personal account for months. The third is treating business savings as a personal emergency fund without recording it. Each creates a transaction that needs explaining later. If one slips through, do not ignore it: record it as drawings or as money the owner owes the business, and settle it in the same month.
