Customer Stories

Loved by Amazon sellers worldwide.

Join the sellers and agencies scaling smarter with SellerMonitor.

We caught a Buy Box loss on our top SKU in 5 minutes instead of 5 days. SellerMonitor literally paid for itself in the first hour. The profit analytics are unmatched.

David Reynolds

Sarah Mitchell

The inventory forecasting alone is worth it. We eliminated stockouts during Q4 last year. I sleep way better knowing SellerMonitor is watching my data.

FAQ

Questions, answered.

Everything you need to know about connecting SellerMonitor to your Amazon business.

How does SellerMonitor connect to my Amazon account?

SellerMonitor connects through Amazon's official Selling Partner API (SP-API) using a secure, read-only authorization. We never see or store your Amazon password, and you can revoke access at any time from Seller Central.

Is my sales and inventory data secure?

Yes. Data is transmitted over TLS and encrypted at rest with AES-256. We're GDPR-aware and only request the read-only scopes needed to surface your analytics — SellerMonitor cannot place orders or modify your listings.

How often is my dashboard updated?

Most metrics — revenue, fees, Buy Box status, and PPC performance — refresh in near real-time via the SP-API. Inventory and competitor snapshots update multiple times per day, so you always act on current data.

Which Amazon marketplaces are supported?

SellerMonitor covers 14 marketplaces across North America (US, Canada, Mexico), Europe (UK, Germany, France, Italy, Spain, Netherlands), and Asia-Pacific (Japan, Australia, India, Singapore, UAE) — all from a single dashboard.

Do you offer a free trial, and is a credit card required?

Every plan starts with a 14-day free trial. No credit card is required to start, and setup takes about two minutes. You can explore the full Growth feature set before you decide.

Can I change plans or cancel anytime?

Yes. Plans are month-to-month (or yearly for ~20% off). Upgrade, downgrade, or cancel from your account at any time — if you cancel, you keep access until the end of your billing period.

What happens if I exceed my plan's order volume?

Nothing breaks. We'll notify you as you approach your limit and prompt you to upgrade when it makes sense. We never charge surprise overage fees, and your data keeps flowing while you decide.

I run an agency with multiple Amazon clients. Is that supported?

Absolutely. The Agency / Scale plan includes multi-account dashboards, 5 team seats, white-label client reports, and unlimited competitor tracking. Book a demo and we'll tailor the setup to your roster.
