Advertising impact
See how campaign spend changes unit economics and where growth turns into profit leakage.

What you receive
A practical workflow, not another generic calculator.
Each product is structured around the decisions marketplace sellers actually face: whether to change price, fund ads, reorder stock, run discounts, or stop pushing a weak SKU.
From order to digital delivery.
Choose the marketplace table, complete checkout, then receive the digital workflow and onboarding questions by email.
Choose the table
Pick the product for your marketplace: Mercado Libre / Mercado Livre or Amazon.
Complete checkout
Your order records the selected digital product, checkout email, marketplace, SKU count, and margin problem.
Receive the workflow
Delivery starts through the checkout email with the table workflow and seller onboarding questions. No physical item is shipped.
Revenue can grow while margin gets weaker.
Merckit focuses on the cost lines that decide whether a sale is worth scaling: marketplace fees, fulfillment, ads, returns, taxes and inventory cash pressure.
The useful question is not only how much you sold.
The useful question is what remains after the marketplace, logistics, ads and operating assumptions take their share. That is why each table is built around SKU-level contribution profit.
