Two Accounts, Almost the Same ROAS, Completely Different Businesses

Household products: 1.24 million EGP in ad spend, 17,680 purchases, 12.02 million EGP in sales. That is a 9.71x return.

Gifts and luxury: 225,000 EGP in ad spend, 1,000 purchases, 2.25 million EGP in sales. That is 8.52x.

Judged on ROAS alone, those look like the same business performing about equally well. They are not remotely the same business, and treating them the same way is how retention budgets get misallocated.

Run the other numbers

Household: 1.24M across 17,680 purchases is roughly 70 EGP to acquire each one, and 12.02M across 17,680 is an average order around 680 EGP.

Gifts: 225,000 across 1,000 purchases is 225 EGP per acquisition, and 2.25M across 1,000 is an average order around 2,250 EGP.

So one costs three times more to acquire a customer, and each of those customers is worth more than three times as much per order.

Why this changes what you do next

In the household account, 70 EGP buys a customer who spends 680 EGP. If that customer buys twice, the economics stop being about advertising at all. Consumables get repurchased. The entire opportunity is in the second and third order, and every pound spent on retention compounds.

In the gifts account, the purchase is tied to an occasion. Someone buying a 2,250 EGP gift is not buying another next month. Chasing repeat purchase there means fighting the nature of the product. The opportunity is in being remembered at the next occasion, which is a different problem with a different budget.

Same ROAS. Opposite instruction.

The question ROAS cannot answer

ROAS tells you what a campaign returned. It tells you nothing about whether the customer comes back, and that second thing usually matters more.

I wrote elsewhere about how ROAS overstates profitability because it ignores product cost. This is the other half of the same blind spot: it also ignores time. A 4x return from customers who buy once is worse than a 3x return from customers who buy four times, and no dashboard will tell you which one you have.

What I check before recommending retention spend

Does the product get consumed? If it does, repeat purchase is available and worth paying for. If it does not, you are working on recall, not retention.

What is the natural gap between purchases? For consumables it might be six weeks. For furniture it might be six years. That gap sets your entire communication rhythm, and most brands email on a schedule that ignores it completely.

Does the second order actually happen today? Not in theory. Pull the numbers. Most brands I ask have never looked, and a meaningful share discover the answer is close to zero, which reframes everything.

The cheapest customer you are ignoring

Someone who bought from you last month already trusts you enough to hand over money. Reaching them again costs a fraction of finding someone new.

In the household account, the difference between customers buying once and buying twice is the difference between 680 EGP and 1,360 EGP of revenue from the same 70 EGP of acquisition cost. Nothing in the ad account produces a swing like that.

Where to start

Pull your last twelve months of orders and count how many customers appear more than once. That single number tells you whether you have a retention problem or a product that was never going to repeat.

Both are fine. Confusing one for the other is not.
