P&L and Ad Efficiency Analysis
We analyse not just whether your products are selling — but whether they are actually generating profit after commission, shipping, advertising, returns and operational costs.
MercanWorks evaluates product-level real profitability, net outcome after advertising, and which products deserve an ad budget. The goal is not more sales — it is more profitable sales on the right products.
What is a P&L Analysis?
A P&L analysis is the process of understanding a product's true profitability by evaluating its revenues and costs together. In e-commerce, a P&L analysis is not simply a matter of subtracting product cost from the sale price.
When calculating the real profitability of a product, the following items must all be considered together:
- Sale price and purchase cost
- Marketplace commission
- Shipping cost and packaging expense
- Ad spend (on a per-product basis)
- Return rate and return processing cost
- Coupon and discount costs
- VAT and other platform-specific deductions
- Operational expenses
Without evaluating these items together, it is impossible to determine clearly whether the product is truly generating profit.
Why Must Ad Efficiency Be Considered Together with P&L?
Advertising performance can be misread if evaluated only through ROAS, clicks or revenue figures.
A campaign may appear to deliver high ROAS. However, if the product's profit margin is thin, the net profit remaining after ad-driven sales can be very weak. For example, a product may be running at a ROAS of 5 — which looks good at first glance. But if the product's commission, shipping, returns and packaging costs are high, the real profit after advertising can be far lower than expected.
MercanWorks seeks to answer this question: Is this ad campaign merely generating sales, or is it genuinely producing profit?
The "Sales Without Profit" Problem
Many sellers see their products selling but fail to see the profit they expected at the end of the month. The reason is usually that product-level costs are not being tracked clearly.
The following causes are typically behind the sales-without-profit problem:
- Commission rate has been calculated incorrectly
- Ad spend has not been tracked on a per-product basis
- Return rate has not been factored in
- Coupon and campaign costs have been overlooked
- Product price has been reduced for competitive reasons but margin has not been protected
- Profitable products are not receiving sufficient ad budget
MercanWorks analyses this problem at the product level. This makes it clearer which products should be scaled, which should be corrected, and which should be paused.
Which Questions Do We Answer?
- Which products are genuinely generating profit?
- Which products sell well but deliver weak net profit?
- Which products deserve an ad budget?
- Which products require price or product page revision before advertising?
- Which products have a break-even ad cost that is too high?
- Which products show good ROAS but still deliver low net profit?
- Which products should have their ad budget increased, reduced or stopped?
- Which products could see profitability supported through title, description or visual brief revision?
How Does MercanWorks Conduct the Analysis?
The product's sale price, purchase cost, commission rate, shipping fee, packaging expense and other direct costs are evaluated. We determine how much net profit the product generates without advertising.
We analyse which products convert ad spend into sales. The focus is not only on ad revenue but on the product profit remaining after advertising.
Each product has a different profit margin, so the acceptable ROAS level also differs. MercanWorks evaluates which products are better suited for advertising using a product-level break-even ROAS framework.
When ad spend is added, does the product still generate profit? The answer to this question is the foundation of product-level ad decisions. If profit is weak, the price, title, description or visuals must be re-evaluated.
Some products should be scaled, some should be strengthened through content and visuals, some should be tested on a low budget, and some should be removed from advertising. MercanWorks classifies products not just by sales volume but by profit potential and post-ad efficiency.
If ad efficiency is low, the problem is not always cost-related. The title may be weak, the description may not be persuasive, the main image may not be strong enough, or the ad copy may not convey the product's real value. This is why P&L analysis must be evaluated alongside product content.

Why MercanWorks?
Because growth in e-commerce is not simply about making more sales. True growth means scaling profitable products with the right ad budget, and re-evaluating weaker products in terms of price, content, visuals or ad strategy.
In P&L and ad efficiency analysis, MercanWorks evaluates products not by revenue alone but by their real profit potential. Product title, description, visual brief, ad copy and ad performance are all read together.
This way, it becomes clear not only whether a product is selling, but whether it is genuinely creating value for the business.
Frequently Asked Questions about P&L and Ad Efficiency Analysis
A P&L analysis is the process of understanding a product's true profit by jointly evaluating its sale price, cost, commission, shipping expense, ad spend, return rate and other operational costs.
An ad efficiency analysis is the process of evaluating the impact of ad spend on sales, conversions and net profit. The goal is to understand not just which ads generate sales, but which generate actual profit.
No. Even if ROAS appears high, net profit after advertising can be low if product cost, commission, shipping, returns and other expenses are high.
No. A best-selling product may fail to deliver the expected value to the business due to a low profit margin, high return rate or high advertising cost.
Ad budget should be planned by jointly evaluating the product's net profit margin, sales potential, product page quality, price competitiveness, return rate and historical ad performance.
Yes. Product profitability is not only a cost matter. Title, description, images and ad copy can all affect the product's conversion rate. If the conversion rate is weak, post-ad profitability may also decline.
Yes. Planning an ad budget without knowing how much profit the product generates is risky. The product's profitability threshold must be understood first, and then the ad budget can be set.
No. MercanWorks does not guarantee sales or profit. The work focuses on analysing the real situation at the product level and helping clients make more informed decisions.
No. This is not an accounting or financial advisory service. MercanWorks analyses P&L and ad efficiency from an e-commerce performance perspective.
No. The pre-analysis tool on this page provides only an estimated assessment. For a definitive analysis, product costs, ad data, return rates and operating expenses must be examined in detail.
