Amazon Buy Box Monitoring | Track ASIN Ownership & Price

The Problem & Our Solution

Stop struggling with unreliable data — get clean, consistent snapshots delivered automatically.

Sound familiar?

Sales dropped but you can't prove when you lost Buy Box (or to whom)

Another seller looks cheaper only after factoring shipping

Unknown sellers keep appearing on your listings

You check the page and it looks fine — but rotation is happening underneath

You export data from dashboards, then spend hours cleaning it

What we do

Capture Buy Box + offer snapshots on your schedule

Each snapshot is a timestamped row — consistent fields every run

Deliver clean files to your systems (CSV/XLSX/Sheets/S3/BigQuery/API)

Same columns, same structure every delivery

If something breaks, we fix it — you don't maintain scrapers

Frequently Asked Questions

Is this only Amazon?

Buy Box monitoring is mainly Amazon. Other marketplaces can be supported depending on structure — ask if you need it.

Do you capture all offers?

We capture Buy Box ownership and key offer fields. If you need deeper offer depth (top N offers) or higher frequency, we scope it.

Can you flag unauthorized sellers?

We track seller data and can flag unknown or unusual sellers based on rules you provide. "Unauthorized" is policy-specific — we don't label it unless you define the rule.

Can I add this to existing Price Monitoring?

Yes. If you're already running Price Monitoring, we can add Buy Box tracking as a separate feed or integrated output.

Is this ongoing or one-time?

Either. Ongoing monitoring is common. Short investigations are also common.

How does pricing work?

Based mainly on marketplace count, frequency, and offer depth — not priced per ASIN.

Can you track Buy Box win rate over time?

Yes. With ongoing monitoring, we capture snapshots that let you calculate win rate and see trends. We deliver the raw data — you can analyze in your BI tools or we can add summary fields.

Do you send real-time alerts?

We deliver scheduled files, not real-time push alerts. For most clients, daily or multiple-per-day snapshots are enough to catch changes. If you need higher frequency, we can scope it.
