If you are profitable on paper but your bank account says different, here’s why
You’ve had a good quarter. Invoices are going out. The P&L looks fine.
And yet you’re watching the bank account like a hawk.
If that sounds familiar, you’re not alone. And — more importantly — you’re probably not doing anything wrong.
This is one of the most common things I see with founders running professional services businesses. The numbers look healthy. The business is growing. But cash always feels tight. Sometimes uncomfortably so.
Here’s the thing: profit and cash are not the same thing. Not even close, most of the time.
Why your P&L doesn’t tell you the whole story
Your profit and loss account records income when you invoice — not when you get paid. So if you land a contract in March and invoice on completion in May, your P&L shows the revenue. Your bank account shows nothing until the client pays. Which, at 30-day terms, might be June. Or later, if they’re slow.
That gap is where most cash flow problems live.
It gets worse when you’re growing. More contracts means more work to deliver upfront. More costs. More payroll. All of it going out before the cash comes in.
Winning more business can actually make your cash position worse. (Cold comfort when you’re looking at a VAT bill.)
The big contract trap
I’ve seen this play out at every level — from SMEs through to large enterprise contracts worth millions. One of the things you always have to look at hard is the cash profile of a contract. Not just the margin. The cash.
The question is: are you effectively funding the client? Deploying resource, absorbing costs, and waiting months to recover it?
No business — at any scale — wants to be its clients’ bank.
Founders hit this all the time. You win something that looks brilliant on paper. You hire, you mobilise, you deliver. And somewhere around month two or three, you realise the cash hasn’t arrived yet, but the costs certainly have.
It’s not a failure. It’s a working capital problem. And it’s fixable — but only if you can see it coming.
What “seeing it coming” actually looks like
This is where cash flow forecasting stops being an accounting exercise and starts being a proper management tool.
Not a spreadsheet you update once a year for the bank. A rolling 13-week view of what’s coming in, what’s going out, and where the pressure points are.
With that in place, you’re not reacting to a cash crisis. You’re spotting it eight weeks out and doing something about it. Maybe that’s negotiating milestone payments on a new contract. Maybe it’s timing a purchase differently. Maybe it’s having a conversation with a client before they become a problem.
The difference between a business that navigates growth well and one that doesn’t is usually not the quality of the work. It’s the visibility of the cash.
A few things worth looking at
Payment terms matter more than most founders realise.
Net 60 feels like a minor detail until you’ve got three clients on it at once.
Invoice earlier where you can.
Milestone billing exists for a reason. If you’re delivering a project over three months, there’s no good reason to invoice at the end.
Understand your cash conversion cycle.
How long does it take from starting work to having the money in the bank? If you don’t know the number, that’s the starting point.
Build a forward view.
Even a rough 13-week cash flow forecast — updated weekly — changes how you make decisions. On hiring. On investment. On whether to take on that contract.
If cash always feels tight despite a healthy P&L, it’s usually structural. Not a one-off blip.
What this has to do with having a finance function
Most founders I talk to aren’t in financial trouble. They’re growing. But they’re making big decisions — on people, contracts, investment — without a clear view of the cash impact.
That’s the gap a fractional FD fills. Not the compliance work (your accountant handles that). The forward-looking, what-does-this-mean-for-cash-next-quarter work.
If you’ve read this and thought “that’s exactly what’s happening with us” — I’ve put together a short guide on managing cash flow in a growing professional services business. It covers 13-week forecasting, payment term structure, and the questions worth asking before you take on a big contract.
