Free CSV profit review

Find low-margin products before they quietly drain profit

What the review looks for

Loss-making products

Products where fees, ads, shipping, product cost, and returns may exceed revenue.

Low-margin SKUs

Items that still make money but may be fragile after small cost or ad changes.

Ad cost pressure

Products where ad cost per order is high enough to deserve closer review.

Pricing candidates

Products that may need a price test, shipping adjustment, or channel comparison.

CSV columns to prepare

Use these columns when possible. If your export has different names, include the closest available fields and mention the marketplace in your request.

What happens after upload

The form submission is sent securely to MarginPilot's Worker webhook.
The CSV is downloaded, parsed, and grouped by SKU or product name.
An initial review summary is emailed to you and to the site operator for follow-up.

Good fit

Amazon, Etsy, Shopify, eBay, or marketplace sellers reviewing product-level profit.
Sellers who already know product cost or can estimate landed cost.
Stores trying to decide which products deserve more ad spend or price testing.

Recommended next step

If you want a dedicated profit dashboard after the free review, TrueProfit is a useful option for tracking product profit, ad spend, shipping cost, and store-level net margin. MarginPilot may earn a commission if you sign up through this link.

Important privacy note

Remove customer names, addresses, phone numbers, emails, card data, and order notes before sharing any CSV. The review only needs product-level financial fields, not buyer personal information.

How this connects to MarginPilot Pro

The free review is a lightweight way to test the workflow before a recurring profit monitor. If the CSV review is useful, MarginPilot Pro can later turn the same checks into a repeatable monthly process.
