Two Numbers, Two Different Jobs

If you run a small business or work as a freelancer, you have probably had a week where your profit and loss report looked perfectly healthy while your bank balance looked terrifying. That is not a glitch in your bookkeeping. Profit and cash flow answer two completely different questions, and understanding the gap between them is one of the most practical things you can do for your business.

Profit is what remains from your income after you deduct your costs for a given period. Cash flow is the money that actually lands in and leaves your bank account, day by day. Profit tells you whether the work is worth doing. Cash flow tells you whether you can pay the bills this month.

Why a Profitable Business Can Still Run Out of Money

Most small businesses invoice on 14, 30 or even 60 day terms. You record the sale when you issue the invoice, but the money may not arrive for weeks. In the meantime, wages, rent, insurance, software subscriptions and supplier bills all leave on time. On paper you are profitable; in the bank you are stretched.

• Unpaid invoices. Money owed to you is not money you can spend. A single slow-paying client can undo a good month.
• VAT you have collected. If you are VAT registered, the VAT on your sales is not your income. It sits in your account until your return is filed and the direct debit goes out.
• Large one-off payments. Equipment, a deposit on a lease, a corporation tax bill or a self assessment payment on account can wipe out a healthy balance in a single day.
• Growth itself. Growing sales usually means bigger debtors and more stock, so a growing business often needs more cash, not less.

Why a Healthy Bank Balance Can Hide a Problem

The opposite trap is just as common. A strong balance can create a false sense of security when there are commitments you have not yet recorded or bills quietly building in the background.

• Supplier bills entered late. If purchases sit in a drawer rather than in your accounts, your profit looks better than it is.
• Customer deposits. Money taken upfront for work you have not delivered is a liability, not profit. You still have to do the work.
• Tax accruing quietly. VAT, PAYE and corporation tax build up between payments. For sole traders, payments on account fall due on 31 January and 31 July, which catches people out every year.
• Seasonal trading. A busy summer can fund a very quiet winter, and a cash cushion can mask margins that are simply too thin.

Being busy and being profitable are not the same thing. If each job barely covers its costs, more work just drains you faster.

A Simple Monthly Routine That Keeps Both in View

You do not need complex modelling. A short, repeatable monthly review will tell you most of what you need to know.

• Check your bank balance and note the date, so you are comparing like with like.
• Pull an aged debtors report and list who owes you what, and when it is due.
• List what you owe and when it leaves, including VAT, PAYE and any loan or finance payments.
• Set aside the tax element of every payment you receive, ideally into a separate account.
• Build a rolling 13-week cash forecast: expected receipts with realistic dates, and known outgoings.
• Read your profit and loss statement alongside those cash figures, rather than instead of them.

Practical Habits That Bring the Two Closer Together

• Invoice the day the work is done. A week's delay in invoicing is a week's delay in being paid.
• Ask for a deposit. A 25% or 50% upfront payment on larger jobs protects your cash flow and confirms commitment.
• Chase politely but persistently at 7, 14 and 30 days past due. A short, friendly reminder early is far easier than an awkward call at 90 days.
• Keep a separate tax account and move the VAT and tax portion of each receipt into it immediately.
• Hold a buffer. Aim for two to three months of fixed costs, built up gradually rather than all at once.
• Pay yourself a regular amount rather than dipping in and out, so your personal finances stay predictable.
• Review subscriptions and regular costs quarterly. Small monthly charges are the quietest drain on cash there is.

When the Figures Pull Apart, Ask These Questions

If your profit and your bank balance are telling different stories, work through the gap rather than ignoring it. Is the profit real, or is it tied up in invoices you have not been paid for yet? Have you set aside everything HMRC will eventually want? Are there costs you have committed to but not yet recorded? Could you shorten your payment terms, or ask for a deposit on the next job?

Profit and cash flow are not rivals. Profit is your long-term scorecard; cash flow is your day-to-day oxygen. Keep an eye on both, review them monthly, and you will make far better decisions about pricing, hiring, taking on work and paying yourself.
