Profitability-first growth is the operating mode where contribution margin, payback period, and net new customers carry more weight in the room than platform ROAS. Three things change when you make that shift. The questions you ask. The work you actually do. The way you report. A fourth one, if I am being generous: you stop confusing efficiency wins with stagnation. This is the companion piece to my conversation with Steve Hutt on the eCommerce Fastlane podcast.

I sat down with Steve Hutt on the eCommerce Fastlane podcast last week to talk about something I think a lot of brand owners feel before they can name it. The top line is growing. The campaigns look fine. The agency report has green numbers all over it. And yet, when the founder opens the bank account on a Monday morning, the cash position is going the wrong way.

Steve put it really well at the top of the episode. He called it a profitability problem disguised as a growth problem. That framing has stuck in my head all week, because that is almost exactly what I see whenever we sit down to open the books with a new partner.

This is the companion piece to that episode. Less the conversation itself, more the question underneath it, which is: what actually changes when you stop reporting against ROAS and start reporting against profit? Three things, in my experience. Maybe four if I am being generous.

The vanity number problem

I do not want to bash ROAS, because it is a useful number for tactical optimisation inside an ad platform. It tells you something about how Meta or Google is reading your campaigns at any given moment. The problem is that the further you scale, the less ROAS tells you about your actual business. You can run a 7x platform ROAS on a campaign and watch your contribution margin shrink for six months in a row. Steve called it a vanity metric. I think that is fair.

There is so much behind that number. The attribution window. What the platform decided to credit. Which audience it pulled from. Whether the customer was new or a recapture. None of that lives inside the headline ROAS figure. So when you set ROAS as the scorecard for the business, you are scoring against a number that does not really describe the business.

Most brand owners I speak to know this on some level. They just have not had the framework to push back on it, because their agency keeps leading with it on the monthly call. That is where the conversation has to change.

Thing one. You start asking different questions

The first thing that shifts when profitability becomes the headline is the questions you ask in the room.

You stop asking "what was our ROAS last week" and you start asking "how many net new customers did we acquire, and what does it cost us to keep them coming back". You stop celebrating an 8x ROAS on a branded search campaign and you start asking how many of those people were going to buy anyway. You stop staring at attributed revenue and you start asking about CAC, payback period, and contribution margin.

I had a partner come to us with a 7x ROAS on branded search. Looked beautiful on the dashboard. The issue was that 80 percent of their Google budget was sitting on brand terms, and brand search is, by definition, capturing people who already know who you are. We flipped the spend mix to roughly 83 percent non-brand, went after net new traffic, and revenue grew 74 percent inside a few months. The branded ROAS dropped. The bank account looked very different.

That is the kind of decision that only gets made when the questions change first.

Thing two. You start seeing different work

The second thing that changes is where the actual work happens. When ROAS is the scorecard, almost all the work happens inside the ad account. Bid changes. Audience tweaks. Creative iteration. Stuff that the platforms are quietly automating away from us anyway.

When profit is the scorecard, the work moves up the value chain. You start looking at the catalogue, because dynamic feeds drive way more revenue than most teams realise and almost nobody is optimising them properly. You start looking at landing pages and customised funnels, because a 1 percent conversion rate lift compounds straight into contribution margin. You start looking at the customer journey, because most brand owners I work with cannot tell me whether someone who buys product A comes back for product B in 30 days or 90 days, and that answer changes their whole forecast.

There are dark arts in all of these. None of them sit inside the ad manager. They sit at the level of the business. And honestly, this is the bit I have come to find most fun. Media buying is being eaten by AI. AI will keep eating more of the bottom level execution. Bid changes, budget shifts, placement decisions and tactical optimisation will become less and less defensible as agency value. What will not be automated as easily is the strategic layer: catalogue work, funnel design, customer journey analysis and the commercial judgement to know which lever actually matters.

Thing three. You start reporting differently

The third thing that changes is the shape of the monthly report itself.

ROAS-led reports are tactical. They tell you which campaign won, which ad set is fatiguing, which creative outperformed. They do not really tell you whether the business is healthier than it was last month. Profit-led reports are commercial. They tell you blended CAC, payback period, contribution margin trajectory, new-customer ratio, repeat rate, and how the marketing engine performed against the P&L.

I am not saying you delete platform ROAS from the deck. You keep it as a tactical view. You just stop letting it be the headline. The headline becomes a number that maps to the bank account.

This is also the moment a lot of agency relationships get awkward, because most agencies have built their reporting around the metric they are most accountable for. Profit-led reporting puts the agency on the hook for things outside their direct control, like product margin or shipping costs or organic traffic. The good news is that the agencies who lean into this end up in genuinely strategic partnerships with their brands. The agencies that resist it are usually protecting the relationship from a conversation they do not want to have.

Thing four. You stop confusing efficiency with stagnation

The bonus one, which I closed the podcast with.

There is this assumption in DTC that growth means top line. If you do not hit your revenue target, you did not grow. The reality is that growth comes in many ways. You might have targeted $10M and hit $9M, but if your efficiency improved by 20 percent in the same period, your business is in a fundamentally stronger position than it was a year ago. That is growth too. It is just growth on a different axis.

Once you start running the business with profit as the headline, this becomes a much easier conversation to have with your board, your finance lead, and yourself. Efficiency wins start counting properly. Contribution margin improvements get celebrated rather than buried. CAC payback shortening becomes a strategic priority, not a footnote.

This is genuinely the bit I find most freeing about working with founders this way. The pressure to chase a top-line number that does not match the underlying economics is exhausting. The shift to profit-led growth gives you permission to make smarter decisions, even when those decisions look slower on the revenue chart.

Where this leaves us

When Steve asked me on the podcast what someone should do if any of this sounded familiar, I told him the long answer is to audit your business, not your ad account. You can audit a Meta account with a script these days. Auditing the business is the work. Top line. COGS. Contribution margin. CAC. Payback. The full picture. That is the conversation worth having, and it is the conversation we sit in with founders week in, week out.

If you want to hear the full version of this, including the bit on the haircare brand, the case for catalogue optimisation, and the line on email being the most undervalued thing most brands own, the podcast is the best place to start.
