PROFIT MATH, BUILT IN
Amazon can't tell you what a sale keeps. MerchPPC can. Every product gets its own profit ceiling — and every ad answers to it.

Sales and ads together

All 7 marketplaces in one dashboard.

Real profit per product

Worked out from your own royalties.

You approve every change

Nothing reaches Amazon without your OK.

MerchPPC is a Chrome extension for Amazon Merch on Demand sellers. It reads your Merch sales, royalties and Amazon Ads data into a database inside your own browser, and that is where the data stays: no copy is kept on our servers. It shows which products earn their ad spend, and nothing it suggests reaches your Amazon account until you approve it in the Publish queue.

Why it exists

Retire the Sunday-night spreadsheet.

Amazon shows your sales in one place and your ads in another. MerchPPC puts them together.

Open it, and the answer is already waiting.

Questions

Questions, answered.

Short answers to what sellers ask first.

Where does my data live?

In your own browser, on your computer. It is not uploaded to our servers. What we hold, and for how long.

Will it change my ads on its own?

No. It suggests changes, and nothing reaches Amazon until you approve it.

Can Claude or ChatGPT change my account?

They can only suggest. Their changes wait in the same list, for your approval.

What does it cost?

The dashboard is free. Every account starts with 7 days of Pro, no card. See pricing.
