Why separate accounts
Mixing business and personal money creates problems that compound quietly and are expensive to unpick later.
- Tax and accounting. Separating transactions after the fact is slow and error-prone. Accountants charge for the time, and the risk of missing a deductible cost or claiming a personal one rises.
- Legal separation. For an incorporated business, mixing funds can undermine the distinction between the company and its owners — the separation that limited liability depends on.
- Credibility. Suppliers, landlords and lenders generally expect payment from a business account in the business name.
- Visibility. You cannot see whether a business is working if its transactions are mixed with grocery shopping.
- Terms of service. Personal account terms commonly prohibit business use, and breaching them can mean the account is closed at short notice.
Cash flow versus profit
These measure different things, and confusing them is one of the most common reasons viable businesses fail.
Profit is revenue minus costs over a period, usually recorded when the sale is made rather than when the money arrives. Cash flow is money actually moving in and out. A business can be profitable on paper and still have nothing in the account, because customers pay on long terms while wages, rent and suppliers are due now.
Growth consumes cash. Larger orders mean buying more stock and paying more wages before the resulting invoices are settled. A fast-growing business can run out of money precisely because it is succeeding, which is why a cash-flow forecast tells you more than a profit figure.
- Forecast the timing, not just the totals
A simple week-by-week view of expected receipts and payments reveals the gaps a monthly profit figure hides.
- Know your payment terms
Invoice terms, when customers actually pay, and what you owe suppliers. The gap between them is the working capital you need to fund.
- Keep a buffer
A reserve covering several weeks of fixed costs absorbs a late payment without an emergency.
- Chase early and consistently
Late payment is normal rather than exceptional. A standing routine collects more than a reaction to a shortfall.
What business banking covers
| Service | What it does |
|---|---|
| Business current account | Day-to-day trading account in the business name. Often carries transaction charges that personal accounts do not. |
| Merchant services | Accepting card payments in person or online. Priced per transaction and as a percentage, with settlement typically a few days behind the sale. |
| Payroll | Paying staff with the associated tax and contribution calculations, usually on a fixed schedule with its own deadlines. |
| Invoicing and receivables | Issuing invoices and tracking what is owed. Some banks integrate this with the account; many businesses use separate accounting software. |
| Business credit | Overdrafts, loans, asset finance and invoice finance. Assessed on business performance, and frequently requiring a personal guarantee from the owners of a small business. |
| Foreign currency | Holding and converting currency for businesses that trade internationally, where the conversion spread can matter more than the headline fee. |
Small-business lending often requires the owner to guarantee the debt personally. If the business cannot pay, you are liable, and limited liability does not protect you for that debt. Read exactly what is being guaranteed and for how long.
What opening an account involves
Opening a business account takes more than opening a personal one, because the institution has to establish who controls the business as well as who you are.
- Business identity — registration details, trading address, and the nature of the business.
- Beneficial ownership — who ultimately owns or controls it, typically everyone above a defined percentage.
- Director and signatory identification — identity and address verification for each person with authority.
- Expected activity — anticipated turnover, payment types and countries traded with, used for ongoing monitoring.
- Regulated activities — some sectors require licenses before an account will be opened, and some are declined outright on risk grounds.
Records and reconciliation
Reconciliation is matching your own records against the bank's. Done regularly it takes minutes and catches errors, duplicate charges and fraud early. Left until year-end it becomes a project.
- Match every entry to an invoice, receipt or payroll record. Unexplained entries are where both mistakes and fraud surface.
- Reconcile on a schedule — weekly or monthly — rather than when something looks wrong.
- Separate duties where you can. In a business with staff, the person who sets up payments should not be the only one who reviews the statement.
- Watch for invoice redirection. Businesses are the main target. A supplier emailing new bank details is the signature of this fraud; confirm by phone on a number you already held.
Frequently asked questions
Can I just use a personal account for my business?
Most personal account terms prohibit business use, and doing so creates tax, accounting and — for incorporated businesses — legal separation problems. It also risks the account being closed at short notice.
My business is profitable but I have no money. How?
Profit records sales when made; cash flow records money when it moves. If customers pay on long terms while your costs are due immediately, you can be profitable and unable to pay a bill. Forecasting timing rather than totals is the usual fix.
Why does business account opening take so long?
The institution must verify the business, its beneficial owners and each signatory, and assess expected activity. Having registration documents and identification ready in advance is the main thing that speeds it up.
