Growth is a staircase, not a slope

New Zealand businesses have told ANZ they are ready to invest.

The July Business Outlook put confidence up 19 points to 56.1. Investment intentions lifted to 22.8. Employment intentions nearly doubled to 18.1. Manufacturers' export intentions reached their highest level since 2000. After the last couple of years that is a good thing to see, and the businesses behind those numbers have earned the optimism.

What those firms are describing is an intention to invest ahead of the curve. They can see the opportunity and they are willing to commit to it before the revenue turns up. Equal parts exciting and scary, and worth some thought if you are running a scaling business, because of the way growth actually lands in your accounts.

Why cost does not behave the way your budget says it does

When we build budgets we model costs as a percentage of revenue, because that is what a spreadsheet does easily. Set the assumption, drag the formula across twelve columns, and cost rises neatly in step with sales.

In reality you commit to that spend in a lump, on a date, at full price.

The second site. The ERP that replaced the one you outgrew. The first GM hire. The quality manager your biggest customer now requires as a condition of the contract. Each one arrives whole and starts costing money the day you sign. The revenue that justifies it arrives in slices over the following two years.

NZIER had capacity utilisation at 90.8% in the June quarter, barely down from 91.2%. At that level most businesses cannot stretch any further. There is no more overtime to run, no more space on the floor, no more hours in your own week. The next tranche of growth has to be bought rather than squeezed, which is exactly what those investment intentions are describing.

What buying a step actually looks like

Take a business making the decision this month. The step costs $600,000 a year. A site, a manager, and the systems around them. From the day you sign that is $50,000 a month leaving the business. Assume it unlocks $6M of new revenue, arriving evenly over 24 months, at a 30% contribution margin.

Here is the shape of it, month by month, showing what each month costs and where cumulative cash sits.

Month 1: down $43,750 for the month, $43,750 of cash gone.

Month 5: down $18,750 for the month, $156,250 of cash gone.

Month 8: breakeven on the month. Cumulative cash bottoms out at $175,000.

Month 12: up $25,000 for the month, $112,500 still to recover.

Month 15: square. Every dollar of the $175,000 is back in the business.

Month 24: up $100,000 a month at full run rate, $675,000 ahead in total.

Four of those dates matter, and none of them is obvious from the annual number.

Month 8 is when the new revenue finally covers the $50,000 a month and your cash stops going backwards. By the time you reach it the step has consumed $175,000 of cash, which is roughly three and a half times the monthly cost most people are carrying in their heads.

Month 15 is when you have earned the whole $175,000 back and you are level with where you started. Month 24 is when the site adds about $100,000 a month after every cost it carries. That is what the $175,000 bought.

All of that assumes the ramp goes exactly to plan. No delay in the fit-out, no slippage on the hire, no customer pushing their start date into the new financial year.

None of it argues against taking the step. Most of the time the step is the right call, and a business sitting at 90.8% capacity that refuses to take one has quietly chosen to stop growing. The argument is for knowing the shape before you sign, because two things can go wrong when you don't.

The first thing that goes wrong: the dip gets managed as a bad year

Revenue is up. Profit is down.

The board asks why margin fell, the management team goes looking for what broke, and a quarter disappears into investigating something that is working exactly as designed.

Nothing broke. You bought a staircase and you are between floors.

This one is recoverable, but it is expensive in attention and it costs the business confidence at the moment it most needs to hold its nerve.

The second thing that goes wrong: the business pulls out at month five

This one is not recoverable.

Around month five, cash is tight and the new revenue still has not arrived at the levels that start covering the outgoings. A shareholder or a board member says the words: maybe we pull back. The cash pressure they are describing is real, and that is what makes the argument so persuasive.

The decision that follows it is what costs you. The $156,250 that has gone by month five is already spent, on the fit-out, the salaries and the systems, and none of it comes back. Pulling out also gives up the $6M of revenue the step was going to produce. You pay for all of it and collect none of it, and you arrive back at 90.8% capacity with less cash than you started with and the same decision still in front of you.

Set against that, holding on costs three more months of pressure to reach breakeven at month eight, and gets your cash fully back by month fifteen.

Month five was always going to look like month five. The reason it feels like a crisis is that nobody wrote down what month five was supposed to look like.

Four questions before you commit

These take about twenty minutes with your numbers in front of you.

1. What does it cost per month from the day we sign, not annualised?

2. How long until the revenue it unlocks covers that monthly cost?

3. How deep does cash go in between, and have we got it or can we fund it?

4. What is the signal that tells us it is working, and what date do we check?

Question three is the one that catches people out. It is a cumulative figure, not a monthly one, and it is usually two to three times larger than the number people are carrying in their heads.

Question four matters more than it looks. Without an agreed signal and an agreed date, every month between signing and breakeven is available to be re-argued, and that is how businesses talk themselves out of steps they were right to take.

Understanding the numbers and the metrics of the staircase from the outset is what gives you clarity on where you are, and the confidence to keep going when things get tight.
