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.

Recommended next step

What to do after the free review

If the CSV review surfaces recurring margin pressure, move into a dedicated profit dashboard or compare whether more owned-channel volume would improve your unit economics.

Profit monitor

Track real product profit after the calculator

When the estimate looks promising, move into SKU-level profit tracking so ad spend, shipping drift, and refunds do not quietly erase margin.

Try TrueProfit

Owned channel

Compare marketplace margin with your own store

If marketplace fees are heavy, test whether a direct Shopify checkout gives you more room after payment fees, shipping, and repeat purchase potential.

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.
