What MerchPPC is

MerchPPC is a Chrome extension for Amazon Merch on Demand sellers. It signs in as you, in your own browser, reads your sales and your Amazon Ads data, and keeps them in a database on your machine. Then it answers the question the Amazon consoles cannot: which of your products earn their ad spend, and which quietly eat it.

Why Amazon's own screens cannot tell you that

Amazon's advertising console knows what a campaign spent and what it sold. It does not know what a Merch product earns you — the royalty depends on the marketplace, the product type and the list price, and none of that is in the Ads report.

So the console can tell you a target's ACoS was 43%. It cannot tell you whether 43% was a good month or a slow bleed, because that depends on a number it does not hold. MerchPPC holds both, which is the whole reason it exists.

Where your data lives

In a database inside your browser. Not on our servers.

That is a real trade rather than a slogan, and it is worth understanding before you install:

• What you get. Your history is yours. Everything works at the speed of a local database rather than a network. If you stop paying us one day, the dashboards keep working and the history is still there.
• What it costs. The data lives on one machine. A second computer starts its own sync, and clearing your browser's storage clears it.

The website handles your account, your plan, and any integration you deliberately switch on. It is not a copy of your Merch and Ads history.

What it will not do

It will not change anything on Amazon without you. Every change it proposes — a bid, a budget, a negative keyword, a new campaign — is staged in the Publish queue and waits there until you read it and approve it, one row at a time.

That is not a setting. There is no autopilot mode to switch on.

What is next

Install and connect takes about five minutes. The first sync takes longer, and what to look at first explains what it is doing while you wait.
