A market with a beautiful ROAS can still lose money. Here is how to build a P and L per market with shipping, returns, payment fees and taxes, so you know which market truly wins.
Measuring per-market profitability means building a separate profit and loss view for each country that goes beyond the ROAS in your ad platform. You subtract the real costs of that country: shipping, returns, payment fees and taxes. Only then do you see which market actually makes money. Two markets with the same ROAS can have a completely different bottom line, and without that P and L you will happily scale the one that loses money.
Why is per-market ROAS misleading?
ROAS measures revenue divided by ad spend, nothing more. Everything that happens after that stays out of view. A customer in one country might pay with an expensive payment method, return more often, or cost more to serve because of the distance to your warehouse. In the ad platform those two markets look identical, while one makes a profit and the other slowly bleeds. Anyone scaling internationally on ROAS alone is deciding on half a picture.
The danger is in scaling. As soon as you shift budget to the market that looks best on the dashboard, you also multiply that market's hidden costs. A country with a beautiful ROAS but a high return rate gets more expensive as you grow, not cheaper. The per-market P and L is your insurance against that trap.
Which costs belong in a per-market P and L?
You do not need to build an accounting system. A simple calculation per market, covering the four big cost items that differ between countries, already gets you far.
- Shipping: distance to your warehouse, local delivery rates and free-shipping thresholds press directly on your margin.
- Returns: return rates vary sharply by country and culture, and every return costs you shipping out, back and handling.
- Payment fees: local payment methods carry different transaction costs, and some popular methods are pricier than a card payment.
- Taxes and duties: VAT rates, import duties on shipments outside your home region and local levies change your net revenue.
Add your product cost to that and you are left with a contribution margin per market. That number, not the ROAS, tells you whether a market is healthy. It does not have to be perfect: a reasonable estimate per cost item is infinitely better than ignoring the costs entirely.
How does this change your decisions?
Once you steer on contribution margin instead of ROAS, your whole prioritization shifts. The market that lagged on the dashboard can, after fair cost allocation, turn out to be the most profitable, simply because customers there return less or are cheaper to supply. Conversely, a country with an impressive ROAS can cost you money through expensive payment methods and high returns. You then move budget to where the real profit sits.
The market with the prettiest ROAS is not always the market that makes you money.
It also shapes your offer and your targets. In a market with high returns you can sharpen your sizing or product information to lower returns, or raise your free-shipping threshold. In a market with expensive payment methods you can lift your ROAS target, so you only scale where it still adds up after costs. Without the per-market P and L you would never find those levers.
How do you keep it practical?
The trap is making this so complicated that you never do it. Start small. Take your biggest markets, gather an average per market for shipping, return rate, payment fees and taxes, and put that next to your ad spend and product cost. Update it quarterly rather than daily. You are not after accounting precision, you are after the big differences between countries that steer your decisions.
Put your findings side by side in one simple overview, with revenue, the four cost items and the resulting margin per market. That way you see at a glance which country is your engine and which one drags on your margin. Update that overview quarterly and use it as the starting point for your budget allocation. It does not need to be a dashboard full of charts: a clear table does exactly the work you need to decide better than on platform ROAS.
This is exactly the work we do in international scaling projects. Buvanha grew with us from €50K to €470K monthly revenue in three months, across six markets, without expanding the team. That only works when you know per market where the profit sits and do not sail blind on one platform metric. The creatives travel across borders, but you judge the economics of each market separately.
Conclusion
Per-market ROAS is a starting point, not a verdict. Only when you allocate shipping, returns, payment fees and taxes to each country do you see which market is truly profitable and which one costs you money while the dashboard glows green. Build a simple contribution margin per market, steer on it and move your budget to where the profit is. Want to tackle an honest profit picture per market?
