There are businesses that look great on paper… and still can’t make payroll.
Why? Because the P&L only tells half the story.
You can analyze earnings all day, but if you miss the timing of cash, you miss the business. AR stretches out. Inventory needs to be rebuilt. Quarterly taxes hit. And suddenly your weakest month can’t cover the loan payment, even though the P&L says you’re “profitable.”
Today, we’re going to look at cash month by month, set guardrails, and map it to your DSCR so you can see whether your loan actually fits the rhythm of the business you’re buying.
I have owned companies with lumpy earnings and even lumpier cash flow, and I have also been a broker packaging these same companies to look far smoother on paper.
That’s the point: Cash is calendar-based, not accrual-based, and the paper version often lies about timing.
The $35,000 June Surprise
In one of my companies, I pay $35,000 once a year for mission-critical software.
On accrual financials it is annualized and smoothed at $2,916 a month.
If I also launch a big marketing push that month, I can push the business underwater and spend July and August rebuilding cash.
The P&L will not warn you about that, but your bank account will.
If you don’t pop the hood and trace how cash actually moves through the months, you aren’t evaluating the business you will operate. You are evaluating a spreadsheet.
There are two concepts I want you to take away today: the two clocks and the Minimum Viable Month.
The Two Clocks
There are two clocks running your life post-close:
- The Cash Clock: Revenue and cash collections arrive on their own schedule. Customers pay when they pay. Seasonality exists. One big bill can land all at once.
- The Debt Clock: Your lender, on the other hand, doesn’t care when revenue arrives. Debt service is fixed, same day, same amount, every month.
When those clocks fall out of sync, you feel the squeeze. You watch last month’s profit evaporate this month, and you still owe the bank.
Minimum Viable Month (MVM)
Banks size your loan on annual debt-service coverage ratio (DSCR). They usually want 1.20x to 1.25x coverage, which means total cash available annually is 20 to 25 percent higher than total debt service. That is fine. Annual DSCR is the language of the loan.

But annual averages can hide monthly cash crunches. I tell buyers to evaluate their Minimum Viable Month, the worst month they can reasonably expect based on seasonality, collections patterns, and big ticket outflows.
If your MVM cannot clear 1.15x coverage, you will be acting as a short term bank to your own business. In other words, you will write the check.
Use annual DSCR to talk to lenders. Use MVM DSCR to protect yourself.
A Simple Walkthrough
Say you are looking at a company doing 2 million in revenue and 400,000 in SDE. That is about 33,000 dollars a month of cash flow in the abstract. Your lender sizes the loan and says annual DSCR is 1.27x. Looks good.
Now it is March, three months after closing, and a big customer pays late. Collections miss by 15,000 dollars. Debt service is still 20,000 dollars, and because this is SDE, there is a good chance you did not get paid either.
If that payment slips further and you only collect 15,000 dollars, your DSCR drops to 0.75x and you are short 5,000 dollars with payroll due on Friday.
This is what the two clocks feel like. Debt service is fixed, but cash floats. When they do not align, you are the bridge.
“Hi, I’m Here to Collect.”
True story. I once walked into the lobby of a customer who was 20 weeks past due. I introduced myself and said, “Hey, I’m Walker. I own the company you owe. I brought the invoices. I’m here to collect.”
And yes, I did it in front of her team.
Why? Because non payment is contagious inside an organization. If a company is not paying suppliers, employees may be next. I needed the social pressure to move us up their payables stack.
As a result, our invoice got paid – quickly.
This is what cash reality looks like when the cash clock slips and the debt clock does not. On the annual model, everything still looks like it works. In March, you became the lender.
Guardrails That Keep You Out of the Ditch
Here is how I translate all of this into operating rules:
1. Set MVM thresholds. Aim for MVM DSCR at or above 1.20x. If you can engineer that, your average DSCR should land around 1.35x or higher. That cushion lets you sleep.
2. Model cash monthly, not just annually. Take last year’s P&L and convert it into a collections calendar. Map out:
- AR timing
- Inventory rebuilds and deposits
- Annual or quarterly outflows
- Seasonality and weak months
Then drop your fixed debt service line through it.
3. Right size overhead to worst case, not best case. Do not staff for September if February pays the bills. Add variable capacity where possible.
4. Build and defend a cash buffer. Set aside one to two months of total outflows and treat it like oxygen.
5. Align big spends with big cash. Schedule marketing pushes, CapEx, and annual renewals in months with strong collections.
6. Tighten collections early and often. Early pay incentives, late fees, weekly AR reviews. The older the invoice, the louder you get.
7. Measure and manage the float. Track the gap between when customers pay and when vendors demand cash. Days sales outstanding, days payables outstanding, and inventory days make up your cash conversion cycle. It is the heartbeat of the business.
Cashflow Health, Defined
I like to think of cashflow health as a simple equation.
Your job as the buyer-operator is to increase reliability through:
- collections discipline
- diversified customers
- locked in predictability with terms
- budgets
- calendarized renewals
- hunting down surprises before they hit you, such as single month spikes, seasonal troughs, and forgotten annual bills
Surprises do not just hurt cash. They hurt morale, decision making, and your ability to lead with confidence.
Bottom Line
A business can look profitable on paper and still choke your cash by month three. If your Minimum Viable Month cannot cover the loan, you will cover the loan. That is how the two clocks work.
Keep them in sync by modeling cash month by month, setting MVM guardrails, and running the business to the calendar of cash, not the story of earnings.
Remember: the bank underwrites annual DSCR. You underwrite survival.
Financial complexity is also another reason why we built Acquisition Lab. After Buy Then Build came out, my inbox filled with people asking for help. I was not going to do it unless we could support buyers at the highest level.
Inside the Lab, we do not just teach how to read a CIM. We train buyers to operate: cash conversion cycles, working capital planning, DSCR guardrails, the first 100 days, the real work.
Managing cash is not a footnote. It is the job.
