Marketplace prices move faster than anyone can check.
Prices change several times a day
By the time someone checks by hand, the Buy Box has moved twice.
Every marketplace is different
Each one has its own listings, sellers and fees, so nothing lines up in a spreadsheet.
Unknown sellers undercut you
New sellers appear on your listings and you find out from a sales drop.
One view of your prices, everywhere you sell.
Know who holds the Buy Box
See who wins it on each listing, at what price, and when it changes hands.
Catch undercutting early
Get told when a seller drops below your price or a new seller joins your listing.
Compare markets like for like
Your products matched across marketplaces and countries, in one currency.
Spot stock-outs
See when competitors run out, so you can raise ads or price while they're gone.

Your data stays yours.
Isolated by design
Your data sits in its own isolated database, never mixed with other clients' data.
Least-access connections
Where we connect to your store or accounts, we ask only for the permissions we need.
You approve every change
Nothing touches your live store or accounts without your sign-off, and every change can be rolled back.
Full audit trail
Every action is logged, by person and time.
Delete on request
Your data is removed when you leave or ask.
Questions
Which marketplaces do you cover?
Amazon (all country stores), eBay, Walmart and Etsy, plus other marketplaces you sell on. Tell us which in the demo.
How often are prices checked?
Daily by default, and several times a day for listings you mark as key.
Do I need to connect my seller account?
No. Monitoring works from public listing data. Connecting your account is optional, for your own sales figures.
Can it change my prices automatically?
It tells you what changed. Automatic repricing can be added as part of your setup.
Can we get the raw data?
Yes, as exports, in Google Sheets or delivered to your database.
How much does it cost?
Pricing depends on your scope, the number of stores or accounts, and whether you want it managed. You'll get a clear proposal after the demo.
Is this an app I install from an app store?
No. We set it up and configure it for you. Where it needs to act on your store, we install a private app built for your store only.
Can we have our own server, or host it ourselves?
Yes. Every client's data is already isolated, and dedicated instances and self-hosting are available.
How long does setup take?
Usually days, not weeks. Larger custom setups are scoped in the proposal.
Can you customize it?
Yes. Custom reports, integrations and rules are part of how we work.
Do you work with agencies?
Yes. Agencies can run it across client accounts, with white-label reports.
What if we stop working together?
You can export your data at any time, and we delete it on request.
Let's look at your marketplace prices together.
Tell us about your business. We’ll come to the demo with your data already loaded.
