I've seen profitable businesses nearly go under. Not because they were losing money — their P&L looked fine. But because they ran out of cash at exactly the wrong moment.
The distinction between profit and cash is one of the most dangerous blind spots in SME finance. You can be profitable on paper and insolvent in practice. And the gap between the two is called cashflow.
How Profitable Businesses Run Out of Cash
It happens more often than you'd think, and the mechanics are surprisingly simple.
You invoiced SGD 200,000 in March but won't collect it until May. Your P&L says March was a great month. Your bank account disagrees.
Your quarterly GST payment lands in May. You've been accruing for it all quarter, so the P&L is clean. But the cash leaves your account in one lump sum, and if your receivables are running late, you've got a crunch.
You hired three people in January for a contract that starts billing in March. Two months of payroll with no corresponding cash inflow. The project is profitable over its lifetime, but the timing mismatch creates a hole.
Your biggest client stretches payment from 30 days to 60 days. They don't tell you — you notice when the bank balance keeps dropping. By the time you adjust, you've funded two months of their operations with your cash.
None of these scenarios involve bad decisions. They all involve bad timing. And in business, timing is everything.
The Difference Between a P&L and a Cashflow Forecast
Your P&L tells you whether the business model works: does revenue exceed costs? That's important, but it's a structural question.
Your cashflow forecast tells you whether the business survives: will you have enough cash in the bank next Tuesday to make payroll, pay rent, and settle your GST? That's an operational question — and it's the one that kills businesses when the answer is "no."
A cashflow forecast takes the same inputs as your P&L — revenue, costs, timing of payments — and resequences them based on when cash actually moves. Revenue is recognised when earned (P&L), but cash arrives when the customer pays (cashflow). Costs are matched to the period they relate to (P&L), but cash leaves when the bill is due (cashflow).
The P&L and the cashflow forecast can tell completely different stories about the same business in the same month. If you're only looking at one, you're seeing half the picture.
What SMEs Get Wrong
Most SMEs that do any form of financial planning focus exclusively on the P&L. Revenue targets, cost budgets, margin goals — all P&L concepts. Cashflow is treated as an afterthought, or worse, as something you manage reactively by checking the bank balance every morning.
The consequences compound quietly:
Vendor payments get stretched — not strategically, but because cash isn't there. Supplier relationships erode. Credit terms tighten.
Hiring gets delayed — not because the role isn't justified, but because the founder isn't confident there's enough cash to commit to another salary. Growth stalls.
Opportunities get passed up — a bulk purchase discount, an early-payment rebate, a new market entry — because cash isn't available when the window opens.
The Fix
A proper cashflow forecast doesn't need to be complicated. At its core, it's a week-by-week or month-by-month view of three things:
Cash in: When will customers actually pay? Not when you invoice — when cash hits the account. Factor in your actual collection patterns, not your credit terms.
Cash out: When do obligations come due? Payroll dates, rent, GST quarters, insurance renewals, vendor payment terms. Map the known outflows.
The gap: Where the timing mismatches create shortfalls — and how many months of cash reserves you need to bridge them.
When we built this for a client, the most immediate impact was that quarterly statutory payments (GST, CPF) stopped being "bill-shocks." They were anticipated, planned for, and funded in advance. But the deeper impact was strategic: the founders built up cash reserves to cover multiple months of operations, which gave them the confidence to invest in growth without the anxiety of wondering whether next month's payroll was covered.
A profitable business with poor cashflow is a business on borrowed time. Fix the forecast, and you buy yourself the headroom to actually use that profitability.
