# Your Highest ROAS Channel Might Be Your Least Profitable One


Sell one $60 product on 3 channels and you'll keep a different amount from each, even though the customer paid the same price and the product cost the same to make. The gap comes from what sits between the sale and your bank account. Each channel charges its own fees, funds its own coupons, sets its own shipping tiers and produces its own returns.

If you sell across several channels, this is the number that decides where your next ad dollar should go. It's also the one that ad dashboards leave out.

## Every channel has its own toll between the click and your bank account

Your own store, Amazon and a social marketplace can all sell the same product, and they differ in ways that add up quickly.

Your own store has payment processing (typically around 3%), shipping you pay or subsidize, and whatever discount codes your email and influencer programs hand out. Marketplaces add referral fees on every sale and often fulfillment fees on top. Social commerce platforms bring affiliate commissions to creators, and some co-fund coupons that come out of your margin. Return rates differ too. Impulse-driven channels tend to see more of them, and every return takes back the sale and often the shipping with it.

None of these costs shows up in your ad platform. The platform knows the cost of the ad and the value of the order. It doesn't know that a quarter of that order disappeared before it reached you.

## A higher return on ad spend can sit on top of a lower profit

Here's an illustration with made-up numbers. You sell a $60 product that costs $18 to make and run it on two channels.

On Channel A, a paid social campaign sending shoppers to your own store, you spend $15 in ads per order. That's a 4.0 return on ad spend. Shipping runs $7, payment processing about $2, the average discount code takes off $5 and returns average $3 per order. You keep $9.96 on each order.

On Channel B, a social marketplace, you spend $12 in ads per order. That's a 5.0 return on ad spend, which looks better. But the platform takes a $3.60 fee, creators earn $9 in affiliate commission, platform-funded coupons cost you $10, shipping is still $7 and returns run higher at $5 per order. Add the $18 in product cost and $12 in ads and you lose $4.60 on every order.

Run 1,000 orders a month through each. Channel A earns about $9,960. Channel B loses about $4,600. Ranked by return on ad spend, Channel B wins. Ranked by which channel you keep, it's the one to cut.

We've covered why that happens at the brand level in our posts on [marketing efficiency and your P&L](https://wayflyer.com/blog/marketing-metrics-impact-profit-and-loss-statement-roas-mer) and on [contribution margin](https://wayflyer.com/blog/contribution-margin-over-revenue). The channel view takes the same logic one step further, because the break-even point moves from one channel to the next.

## Profit on ad spend gives each channel its own break-even

Break-even MER tells you how efficient your marketing needs to be across the whole business. Profit on ad spend asks the same question for each channel: after every cost tied to that channel's orders, how much profit does each ad dollar return?

In the example, Channel A returns about $0.66 of profit for every $1 of ads. Channel B returns negative $0.38. A channel can be well above break-even on paper and still sit below it once its own fees and returns are counted.

This matters most when you scale. Efficiency usually softens as you add budget, and a channel that clears break-even by a thin margin at $10,000 a month can drop below it at $30,000. Knowing each channel's break-even before you raise the budget tells you how much room you have.

## Product margin changes again inside each channel

Channels are one layer. Products are another, and the two interact.

A brand with 40 SKUs rarely earns the same margin across them. One or two products usually carry the business, with a healthy price, a low return rate and light shipping. Others sell plenty of units but give most of the margin back through heavy discounting, bulky shipping or high returns.

Then the channel layer reshuffles things. A candle that clears a 45% margin on your own store can fall below 20% on a marketplace once fees and shipping tiers apply. A bulky item that's fine on your store can become unprofitable where fulfillment fees are charged by size.

Looking at product margin without channel, or channel margin without product, gives you half a picture. You need both on the same screen to see which product on which channel deserves your money.

## Acting on the answer takes cash you may not have yet

Say the numbers point somewhere clear: one product earns its keep on one channel. The right moves follow. Buy deeper on that product, raise the ad budget and maybe open a second channel with the same product.

All three cost money up front, and sales don't turn back into cash until after the spend. Inventory has to be paid for before it sells. Ad spend goes out daily while revenue lands later, and a new channel brings its own startup costs before the first payout. An owner can see exactly where the next dollar should go and still be short of the dollars.

Bank loans can take weeks, and the paperwork assumes a business with fixed assets. Equity means permanent ownership traded for a temporary cash gap. Neither matches an investment that pays back in weeks.

## BeProfit and Wayflyer put the financing next to the decision

That's why we've partnered with [BeProfit](https://www.beprofit.ai/?utm_source=wayflyer&utm_medium=referral&utm_campaign=wayflyer-partnership&pagesense_source=1686608000001962003&utm_term=&utm_content=blog). BeProfit gives multi-channel owners the full profit picture: every cost line behind net profit, by channel, by product and by order. Wayflyer provides the financing to act on what that picture shows.

Through BeProfit, users can see an indicative Wayflyer financing offer in the same place they found the insight. When you're ready to move forward, you stay in BeProfit until Wayflyer needs to connect to your bank accounts. At that point you're taken to Wayflyer to finish the application. Wayflyer financing can be funded in as little as 24 hours, and repayment is a share of your sales, so it rises and falls with your revenue instead of arriving as a fixed monthly payment.

In practice, that looks like this:

- **Back your best channel.** When profit on ad spend shows one channel clearly ahead, you can raise its budget while the numbers are still current.
- **Restock what earns its keep.** Finance inventory for products that carry margin after product cost, shipping and fees.
- **Expand on proven margins.** Open the next channel with products whose margins you've already seen hold up.

Wayflyer doesn't take equity in your business, and you decide how much to draw and when.

## Check your numbers, then check your options

Start with your own channels. For each of your top 3, pull product cost, shipping, fees, discounts, returns and ad spend and work out profit on ad spend. If a channel's ranking changes once you use profit instead of return on ad spend, you've found money that was going to the wrong place.

BeProfit does that calculation for you across every channel and product, updated as orders come in. And if it shows you a move worth making, check the financing offer in your BeProfit account.
