Cashflow isn’t the same as profit — and confusing the two is one of the most common reasons healthy businesses struggle. This guide breaks it down into practical, weekly steps you can actually use.
You can have a record month for sales and still feel cash-strapped. That’s not a contradiction — it’s a cashflow problem. Profit tells you how much you’ve earned on paper. Cashflow tells you how much money is actually in your account right now. This guide gives you the tools to understand, forecast, and take control of yours.
1.The Cashflow Formula
Opening cash is what you started the month with. Cash in is everything that actually landed in your account — not what you invoiced, but what you received. Cash out is every payment that left. The closing cash is your real position.
2.Build an Annual Cashflow Forecast
A forecast isn’t a prediction of the future — it’s a plan you update as things change. Here’s how to build one that actually gets used.
Money Coming In
- Customer sales & payments
- Grants or funding
- VAT refunds
- Any other income
Money Going Out
- Wages & payroll
- Rent & utilities
- VAT & tax payments
- Suppliers & loan repayments
Once you’ve mapped your money in and out, add a confidence level to each line. This turns your forecast from a guess into a genuinely useful planning tool.
3. Close the Gaps
Cashflow gaps are the spaces between when you earn money and when you actually receive it. Three strategies will shrink them fast.
Shorten Debtor Days
- Request deposits upfront
- Bill at milestones, not completion
- Set clear payment terms from day one
- Invoice on the day work is done
- Chase at 7, 14, and 21 days
Smooth Your Payments
- Negotiate payment terms with suppliers
- Spread costs across the month
- Avoid end-of-month payment pile-ups
And always — always — work towards a cash buffer.
6 to 8 Weeks
A buffer isn’t a luxury. It’s insurance against a slow month, a late payment, or an unexpected bill. Build it gradually if you need to — even two weeks of cover is better than none.
4. Habits That Keep Cash Flowing
Small, consistent actions make a bigger difference than a one-off review. Build these into your routine.
Don’t batch invoices at the end of the week. Send them the moment the work is done — every day of delay is a day your cash is sitting with someone else.
Weekly if you have high volume, monthly if you don’t. When something is overdue, follow up — politely but firmly. Aged debt rarely pays itself.
Unsold stock is cash trapped on a shelf. Order based on what’s moving, not what feels safe. Dead stock is dead cash.
Every business has quieter periods. If yours dips in summer — or at Christmas, or in January — plan for it months in advance, not weeks.
5. Warning Signs to Watch For
These are the red flags that suggest your cashflow is under pressure — even if your sales look healthy on the surface.
- Sales are rising, but cash is falling. Money is being earned but not collected fast enough.
- You have a lot of work in progress, but slow invoicing. You’re doing the work — but not getting paid for it on time.
- One customer makes up more than 30% of your revenue. If they’re slow to pay — or disappear — your cashflow takes a serious hit.
- Tax or VAT bills arrive as a surprise. Calendar your due dates in advance. Ring-fence the funds as soon as you can.
6.Turn Insight Into Action
Knowing your numbers is only useful if you act on them. Here’s how to make cashflow management a habit, not a chore.
Now, commit to a simple weekly rhythm:
-
Every Friday — 20-minute cash reviewCheck your dashboard. Are you on track? Has anything changed? Adjust your forecast if needed.
-
Every month — review Aged Debtors & CreditorsSpot the slow payers and the overdue suppliers. Act on anything that’s more than 30 days old.
