Your Marketing Budget Is a Finance Problem Wearing a Marketing Costume By Abhinav Prakash, Co-founder, Prime Signal

I want to make an argument that will annoy most people who work in Indian advertising, including some who work for me.

The majority of underperforming marketing budgets in this country are not underperforming because of the marketing. They are underperforming because the business underneath them cannot afford the customer it is buying. And no amount of creative, targeting or channel optimisation fixes a number that was broken before the first rupee went out.

I have spent the better part of a decade sitting between those two rooms — the finance room and the marketing room — and I can tell you they are usually not speaking the same language, or in some cases, speaking at all.

The conversation that doesn't happen

Here is a scene I have watched more times than I can count.

The marketing head reports a cost per acquisition of ₹640 and calls it a good month, because last month it was ₹710. Everyone nods. Nobody in the room can state, from memory, what the company's contribution margin per order actually is after returns, discounting, payment gateway charges, shipping, packaging and the cost of the free sachet in the box.

When we do the arithmetic in a diagnosis, the answer is frequently that the contribution margin is around ₹500. Which means every single one of those celebrated acquisitions destroyed ₹140 of value, and the better the marketing team performed, the faster the company lost money.

That is not a marketing failure. It is a failure to define what winning means before starting to play.

At Prime Signal we run compliance and finance as a service line sitting directly alongside performance marketing, and people ask why an agency would do that. This is why. We are not being comprehensive for the sake of it. We are refusing to optimise a metric that nobody has validated.

Three numbers that should exist before any campaign

If you take nothing else from this column, take these.

One: your true contribution margin per unit, after everything. Not gross margin. Not the number in the pitch deck. The number that survives returns, RTO, discount codes, marketplace commission, logistics and every cost that scales with volume. In Indian D2C, the gap between the gross margin a founder quotes and the contribution margin that actually exists is routinely twenty percentage points.

Two: your payback period in months, not your lifetime value multiple. LTV to CAC ratios are the most abused figures in Indian startup reporting, because LTV is a forecast and CAC is a fact. A 4:1 ratio built on a projected three-year customer life is a story. A ninety-day payback period is a balance sheet. If your working capital cycle is sixty days and your payback is nine months, you do not have a growth engine, you have a financing requirement — and you should be raising debt, not buying traffic.

Three: your repeat rate by cohort, tracked monthly. Not blended. Blended repeat rates hide dying cohorts behind new-customer volume, which is precisely the moment when a business feels healthiest and is most at risk.

None of these are marketing numbers. All three determine whether a marketing budget is an investment or a leak.

What compliance has to do with growth

The second half of my argument is less popular still.

Indian businesses at the ₹5 crore to ₹50 crore revenue band routinely treat compliance as an annual inconvenience handled by an external consultant in the last week before a deadline. Then they attempt to raise capital, or sell to a larger buyer, or take on institutional debt to fund inventory — and discover that eighteen months of untidy books have made them un-diligenceable.

I have seen good businesses lose a term sheet not because the growth was fake, but because the growth could not be evidenced. Revenue recognised inconsistently. Related-party transactions unexplained. GST input credits unreconciled. Marketing spend booked in three different heads across two entities, making channel-level return on ad spend impossible to reconstruct after the fact.

That last one matters more than founders realise. If your books do not let you reconstruct what you spent per channel per month, then your historical performance data is not an asset. It is an anecdote. And you will keep re-learning the same lessons every time the marketing team changes hands.

Clean books are not hygiene. They are the substrate on which every growth decision either becomes knowledge or evaporates.

The uncomfortable version

The advice most agencies give a struggling business is to spend more, spend better, or spend somewhere else. All three assume spending is the answer.

Sometimes the honest recommendation is that the company should stop acquiring for a quarter, fix its margin structure, clean its reporting, and come back when a rupee of spend is capable of returning more than a rupee. That recommendation costs the agency money to give. It is still usually the right one.

Across roughly 260 businesses we have worked with — from nutrition brands like Nutrabay and Miduty to manufacturers and clinics — the pattern holds with uncomfortable consistency. The companies that compound are almost never the ones with the cleverest campaigns. They are the ones where the CFO and the CMO look at the same sheet.

Before you approve next quarter's budget, ask your finance lead and your marketing lead to independently write down the cost of acquiring one customer and the profit from one customer. Then compare the two pieces of paper.

If the numbers don't match, you have found your growth problem. It was never in the ad account.
