Not every customer who spends more money is more profitable.
A customer who generates $10,000 in revenue sounds more valuable than one who generates $3,000.
But revenue doesn't tell the whole story.
Imagine:
Customer A
Revenue: $10,000
Discounts: $1,500
Support costs: $1,000
Returns: $800
Delivery & other costs: $1,200
Estimated contribution: $5,500
Customer B
Revenue: $6,000
Discounts: $300
Support costs: $200
Returns: $100
Delivery & other costs: $600
Estimated contribution: $4,800
Customer A still creates more value.
But the gap is much smaller than the revenue numbers suggest.
Now imagine another customer generating $4,000 in revenue but requiring constant support, frequent refunds, and heavy customization.
Suddenly, the “big customer” might not be the best customer.
This is why I find customer profitability more interesting than simply looking at customer revenue.
For each customer segment, consider:
→ Revenue
→ Direct costs
→ Discounts
→ Returns/refunds
→ Support time
→ Acquisition cost
→ Delivery or servicing costs
Then ask:
“How much value does this customer actually leave behind?”
This can completely change how a business thinks about growth.
Instead of:
“How do we get more customers?”
You might start asking:
“Which customers are actually worth acquiring more of?”
And that can influence:
• Marketing strategy
• Customer segmentation
• Service levels
• Product design
• Sales priorities
• Retention strategy
Growth becomes much more powerful when you know which type of growth creates value.
💬 If you had to choose, would you rather have 100 customers generating $100 each or 20 customers generating $500 each?
And why?

Revenue is growing. But is your cash flow getting healthier?
A business can be having its best sales month ever and still feel financially stressed.
Why?
Because revenue isn't cash flow.
As a business grows, a few things can happen at the same time:
→ More invoices are issued, but customers take longer to pay.
→ More suppliers mean more bills sitting in Accounts Payable.
→ More transactions make bookkeeping harder to keep clean.
→ More employees and tools increase operating costs.
→ More sales can create a bigger working capital gap.
That's why I think Accounts Receivable and cash conversion deserve as much attention as revenue growth.
A few numbers I like to keep an eye on:
1. Accounts Receivable Aging
How much cash is still sitting with customers?
2. Days Sales Outstanding (DSO)
Are customers taking longer to pay as the business scales?
3. Accounts Payable
Are upcoming obligations putting pressure on cash?
4. Bank Reconciliation
Can management actually trust the cash balance they're looking at?
5. Operating Cash Flow
Is the business actually generating cash from its operations?
Growth should ideally create more financial capacity, not just more transactions.
Sometimes the most valuable finance work isn't finding another way to increase revenue.
It's making sure the money you've already earned actually makes its way into the business.

If one person can create a supplier, approve the invoice, and make the payment — you have a control problem.
Small businesses often don't think much about internal controls.
It makes sense.
When the team is only 3–5 people, everyone wears multiple hats.
But that's exactly when small financial mistakes can become expensive.
Consider a simple accounts payable process:
Step 1: Someone creates a new supplier.
Step 2: The same person receives the invoice.
Step 3: They approve the invoice.
Step 4: They make the payment.
Nothing looks obviously wrong.
But there is no independent checkpoint.
A stronger process might separate at least some of these responsibilities:
Create → Verify → Approve → Pay → Reconcile
You don't necessarily need a huge finance department to do this.
Even a small business can introduce simple controls:
→ Two-person approval for payments above a threshold
→ Separate supplier creation from payment approval
→ Monthly bank reconciliation
→ Review of unusual transactions
→ Clear documentation for expenses
→ Regular review of outstanding invoices
The goal isn't to make the business bureaucratic.
It's to make sure one mistake — or one bad decision — doesn't automatically become a financial loss.
And internal controls aren't only about preventing fraud.
They're also about catching:
• Duplicate payments
• Incorrect invoices
• Missing transactions
• Unauthorized expenses
• Data-entry errors
• Unusual spending patterns
A good financial system should answer two questions:
“Where did the money go?”
and
“How do we know it went there for the right reason?”
The second question is where financial controls come in.
💬 What's one financial control you think every small business should have, even with a very small team?

Growth can make a business financially weaker.
We usually treat growth as a good thing.
More customers.
More revenue.
More orders.
More employees.
But revenue growth doesn't automatically mean financial health.
Sometimes, the faster a business grows, the more cash it needs to survive.
Imagine a company that increases sales by 40%.
Sounds great.
But at the same time:
→ Customers take 60 days to pay
→ Inventory needs to be purchased upfront
→ Suppliers require payment within 30 days
→ Hiring increases fixed costs
→ Discounts reduce gross margins
The P&L might look impressive while the bank account tells a very different story.
This is why I think one of the most important questions in finance isn't:
“How fast are we growing?”
It's:
“Can our cash flow support the growth we're creating?”
A healthy growth strategy should connect the following:
Revenue → Gross Margin → Working Capital → Cash Flow → Return on Investment
Growth that consumes cash faster than the business can generate it can become a problem very quickly.
And sometimes, the best financial decision isn't to grow faster.
It’s to grow better.
That means understanding which customers are profitable, which products generate real margins, how quickly cash converts, and where additional investment actually creates value.
Growth is a strategy.
Cash flow is the reality check.
