For Etsy, Shopify, eBay & beyond

You know your revenue.
Do you know your profit?

Etsy, Shopify, and eBay show you sales and fees — not what you actually made after cost of goods, ads, and shipping. MarginMoose does the math and tells you what’s really working.

No credit card needed for your first upload.

Real math. Real numbers. No guessing.

Your dashboards are lying to you — by omission

Revenue isn’t profit

Etsy shows what customers paid. It doesn’t know what your product cost you to make or source.

Ad spend creeps up quietly

A few extra dollars per sale here and there, and a winning product turns into a loser — until someone actually adds it up.

Multiply that by three platforms

Etsy, Shopify, eBay — each with its own export, its own fees, its own blind spots. Tracking it by hand doesn’t scale.

How it works

01

Upload your CSV

Export your orders from Etsy, Shopify, eBay, or anywhere else that gives you a CSV. We auto-detect the columns for the big three — anything else, map it once.

02

Enter your costs — once

Tell us what each product actually costs. It’s saved for good — future uploads only ask about new SKUs.

03

See true profit per product

Revenue, fees, shipping, ads, and cost of goods — broken down per SKU, automatically.

04

Get told what to do about it

A plain-English summary points out what’s losing money — right next to the real numbers, so you can check its work.

Works across every channel

Etsy, Shopify, and eBay auto-mapped instantly. Any other platform’s CSV works too — just map the columns once.

True profit, per product

Sortable table, real margin %, loss-making products flagged in red.

Costs you enter once

They persist forever. Future uploads only ask about new SKUs.

AI that explains, never guesses

Insights come from numbers already computed in code — the AI interprets, it never calculates.

Your numbers are real. Your customers’ data isn’t ours.

Deterministic math, always

Every number on your dashboard comes from plain code, not an AI guess. The AI only ever explains numbers that are already correct.

Customer data never touches our servers

Names, emails, and addresses are stripped out the moment you upload — before anything is stored. We only ever see aggregated product numbers.
