DON’T BUILD YOUR BUSINESS AROUND YOUR BEST MONTH

Topics:

Nahuel Hilal built a tattoo and piercing brand into a multi-million dollar business.

It started scrappy, it grew fast, and it looked like the kind of growth story owners dream about.

And then he did what a lot of owners do at that moment:

He made “we’ve arrived” commitments.

He went from running the operation out of apartments to signing a long lease and starting a major buildout. At first numbers came in high, so he told the developer, “I have $400,000. That’s all I have.”

They came back at $500,000 and he agreed and they got started planning. Then… before construction even breaks, they tell him it’s $900,000.

And while that was happening, revenue dropped. Busting through to a new revenue high each month then became peak revenue of the past.

That’s the trap.

When you build your cost structure around your best year, a normal dip doesn’t just reduce profit.

It strips away your options.

WHY A “SMALL” REVENUE DIP HITS WAY HARDER THAN YOU THINK

Most owners mentally model revenue like a volume knob: “If revenue is down 20%, we’ll just be down 20%.”

That’s not how it works once you have fixed costs.

Here’s a simple example using clean numbers:

  • Revenue: $100k → $80k (down 20%)
  • Gross margin: 40%
  • Gross profit: $40k → $32k (down $8k)

But fixed overhead doesn’t follow the proportional decrease:

  • Fixed overhead (rent, base payroll, software, insurance, etc.): $30k
  • Operating profit:
    • At $100k revenue: $40k - $30k = $10k
    • At $80k revenue: $32k - $30k = $2k

Revenue fell 20%.

Profit fell 80%.

And that’s not the real problem… the real problem is cash.

In real SMBs, cash is rarely smooth:

  • A couple customers pay late.
  • A vendor wants payment now.
  • Payroll hits every two weeks no matter what.
  • Taxes don’t show up until they do.

When you have profit, you have room to absorb normal timing swings.

When profit gets crushed, those same timing swings start to feel like emergencies.

That’s why owners can have a “profitable business” that suddenly feels broke.

It’s not always because they’re lying to themselves but because they didn’t understand how fast profit can evaporate once fixed costs exist.

If the first pain is profit and the second pain is cash, the third might be even more painful. The third pain (the one that matters most) is optionality.

When cash tightens, you lose options like:

  1. Financing options shrink: in a strong season, you can get all you want (line of credit, equipment financing, refinancing) whenever you want it. But when the business is tight, financing becomes expensive, slow, or unavailable. Banks don’t love volatility and when your numbers get tight, your leverage disappears.
  2. Operating options shrink: the expenses you want to cut are often the ones you can’t cut. Long term commitments (leases, debt, payroll) don’t care about revenue. So what do you cut instead? Marketing, good people, easy to cancel contracts. It provides short term relief but can sabotage the business long term.
  3. Strategic options shrink: once the business gets tight, you stop making proactive decisions and have to switch to reactive ones. Instead of hiring ahead of growth you’re asking “can we make payroll?” Instead of investing in systems or acquisitons, you’re asking “can we delay it another 30 days?” This traps you and forces you to make less-than-ideal trade-offs.

The loss of options is when you make mistakes and these mistakes are the things that can put your business in a tailspin and hurt your ability to continue on after the crisis.

THE FOUR TESTS TO RUN BEFORE YOU ADD FIXED COSTS

I’m not trying to turn you into a pessimist, but instead trying to help you protect your options.

Stress tests are how you do that and below I give you four to think through.

TEST 1: THE BASELINE CYCLE TEST

Most owners plan like their best months are normal, but forget about seasonality or down months.

Your business has a cycle, even if you don’t like it. So before you model anything, find your baseline:

  1. Pull the last 24–36 months of monthly revenue.
  2. Identify:
  • your best month
  • your worst month
  • your typical month
  1. Ask: “How often does a down quarter show up in our business?”

If the answer is “every year,” then down quarters are not a surprise. They’re normal.

And if a down quarter is normal, planning like it’s a surprise is a choice.

TEST 2: THE REVENUE DROP TEST (20% AND WORSE)

Start with the clean baseline test:

  • What happens if revenue goes from $100k → $80k for 90 days?

Then run a “we don’t expect it, but we respect it” test:

  • What happens at $100k → $70k?
  • What happens at $100k → $60k?

You’re not predicting disaster, but you’re identifying what breaks first.

If you have a big customer concentration that could cause more than a 20% dip, make sure you model for that scenario.

TEST 3: THE MARGIN COMPRESSION TEST

Revenue can be flat and the business can still get tighter if relationships with suppliers are strained.

Run this:

  • Revenue stays at $100k
  • Gross margin drops 3–5 points (40% → 35% or 37%)

Ask: “What happens to profit?” and “What happens to cash buffer?”

Some businesses may not have this pressure but if you do it's important that you understand the overall profit and cash impact of big gross margin swings. If fuel is a part of your delivery and economic conditions change rapidly, you can find yourself hurting when you wouldn't be if you had just reacted more quickly.

Doing this modeling helps you understand which things could cause this sort of impact.

TEST 4: THE CASH GAP (COLLECTIONS) TEST

Assume your customers pay slower for 60–90 days.

Not because they’re bad, but because life happens.

Ask: “Can we still cover payroll and fixed payments without a scramble?”

If the answer is “no,” you don’t have a growth problem.

You have an options problem.

WHAT TO DO (BUILD A BUSINESS THAT CAN BREATHE)

Here are the practical moves that keep you from building your life around your peak:

  1. Build a downside budget: What do we keep at $80k revenue? What do we cut at $80k revenue?
  2. Reclass your expenses: fixed vs actually optional. If you can’t undo it in 30–60 days, treat it as fixed.
  3. Set a fixed-cost rule: No new fixed cost unless it passes your stress tests (revenue, margin, collections).
  4. Hold real cash reserves on standby: Cash reserves are not “lazy money.” Cash reserves are options. They prevent forced decisions and expensive financing. For the full breakdown, see this article where we broke down how much cash reserves to keep on hand.
  5. Build flexibility into commitments: shorter terms where possible and don’t stack long commitments at the same time (lease + hires + debt).

Taking these actions will build resilience into your business and that's really all we're trying to do.

One more bonus for you: STOP FINANCING YOUR LIFESTYLE WITH PEAK REVENUE.

This is the one nobody wants to hear, but it matters: When you lock in a personal lifestyle off-peak profit, you add unnecessary risk to the business and stress to your life.

It seems most business owners don't do this. Most are much more conservative, but there is a certain subset of owners who match their lifestyle to whatever peak revenue is. When you do this, you create not only personal stress but business stress.

This stress seems innocuous at first, but over time, it can lead to bad decisions.

Peak years are a gift. They are not a guarantee.

Don’t turn a great year into a permanent obligation.

YOUR NEXT STEP TODAY

In the next 24 hours:

  • Pull the last 24–36 months.
  • Find your baseline dip.
  • Run the other 3 stress tests.
  • Circle what breaks first.

That “first break” is your real constraint to work on. Figure out how to fix it and then move to the next.

The goal isn’t to avoid down quarters. The goal is to stay dangerous when they show up.
