The Monday-Morning Numbers (That Aren't Your Bank Balance)

By Sophie Wright, founder of WrightCFO and The MOB's resident finance voice

(Yes It’s technically Tuesday, but let’s be honest, today feels like a Monday!)

Most founders I work with have the same Monday-morning ritual.

Coffee. Phone. Banking app. A quick glance at the balance. Then either a small wave of calm, or a small wave of dread — depending on what the number says.

I want to gently break it to you: 

that number is not telling you the truth.

Your bank balance on a Monday morning is a snapshot of one moment, divorced from everything that's about to happen this week. It doesn't know about the VAT bill due on Friday. It doesn't know your biggest client is forty days late paying. It doesn't know you've just signed a contract that will pay £8,000 in three weeks.

So it makes you feel calm when you should be planning, and panicked when you're actually fine.

After a decade of working with founders building businesses from £500K to £30M, I can tell you the women who scale calmly are the ones who replace the bank-balance habit with something better. It takes about ten minutes. Here are the four numbers I'd put in front of you instead.

1. Cash runway, in weeks

Not months. Weeks.

Months feel abstract. Weeks feel like time you can actually picture — three school runs, a half-term, the gap before payday.

The maths is simple: take the cash you have, subtract the bills you definitely have to pay in the next month, and divide what's left by your average weekly outgoings.

If the answer is more than twelve weeks, you have breathing room to make decisions. If it's between four and twelve, you need to be careful about new commitments. If it's under four, every decision this week is a cash decision, full stop.

This is the single number that tells you what kind of week you're having before the week has started.

2. Debtor days (or: who owes you money, and for how long)

This is the unglamorous one that quietly kills small businesses.

Pull up your invoices and ask: how many days, on average, are my customers taking to pay me? If it's over thirty, you are funding their cash flow with yours. If it's over sixty, you have a problem you may not have noticed yet because the work feels like it's going well.

The fix is rarely confrontation. It's usually structural — taking deposits, invoicing earlier in the month, switching to standing orders for retainers, or politely automating the chasing so you don't have to be the one asking.

The mums I work with often hate chasing money. I understand it. But unpaid invoices aren't a relationship problem; they're a system problem. Fix the system once and you stop having to be the bad guy every month.

3. Gross margin on last month's biggest job

Not your overall profit. The margin on your biggest job, specifically.

Take the revenue from it. Subtract the direct costs — the freelancer you paid, the materials, the software, the hours you spent at your true hourly rate. What's left is your gross margin on that piece of work.

Founders are often shocked the first time they do this. The job that "felt good" was actually loss-making once they paid themselves properly. The client they were nervous about was the most profitable one they had.

You don't need to do this for every job. Just the biggest one each month. Patterns emerge fast.

4. Committed costs vs committed revenue

This is the one that separates founders who sleep well from founders who don't.

Committed costs are the bills you have to pay in the next ninety days regardless of what happens — rent, salaries, software subscriptions, your own drawings, tax pots.

Committed revenue is the money you are genuinely confident is coming in over the same period — signed contracts, retainers, recurring subscriptions. Not "hopeful" pipeline. Not "they said they'd probably go ahead." Signed.

If committed revenue comfortably covers committed costs, you can spend this week on growth. If it doesn't, you spend this week on sales. That clarity alone is worth the ten minutes.

The truth nobody tells you

Looking at your bank balance feels like financial discipline. It isn't. It's financial anxiety dressed up as financial discipline.

These four numbers take longer the first time — maybe an hour to set them up properly in a spreadsheet. After that, ten minutes on a Monday morning, with your coffee, will tell you more about the health of your business than the bank app ever could.

You'll know what kind of week to plan. You'll spot problems before they become emergencies. And, quietly, you'll stop carrying that low-grade financial dread that so many founder-mums describe to me as "the thing I think about at 3am."

You don't need a finance team to do this. You just need to look at the right numbers.

Start where you are. Build the habit. Your business will tell you what it needs — but only if you ask it the right questions.
