THE RISK
One bad spreadsheet can create expensive marketplace mistakes.
Supplier feeds change constantly. A misplaced decimal, incorrect mapping or sudden stock jump can become a catalog-wide problem if it reaches Seller Central unchecked.
Unexpected price jumps
Large increases or crashes can hide in thousands of routine rows.
Quantity mistakes
Stock wipes and implausible increases deserve a closer look.
Malformed data
Missing products and damaged identifiers can silently break updates.
WHO IT'S FOR
Built for Amazon sellers working with supplier feeds.
Sellers receiving regular supplier spreadsheets
Catalog teams reviewing price and stock updates
Larger operations that want a review step before Seller Central

FAQ
Clear answers before you start.
FeedGuard is designed as a review layer, not an automatic marketplace connection.
Does FeedGuard upload directly to Amazon?
No. The current version generates a reviewed Amazon-compatible file that the seller uploads manually to Seller Central.
Does FeedGuard change my prices automatically?
No. FeedGuard analyzes the feed and flags potentially unsafe changes for review.
Which files are supported?
CSV and XLSX supplier files are supported.
What happens to blocked rows?
Blocked rows are excluded from production export by default.
Do I need an Amazon API connection?
No, not for the current version.
Is my supplier data used to train AI?
No. Uploaded supplier data is not used to train AI systems, and no AI decides whether a row passes.
How much does FeedGuard cost?
FeedGuard's beta launch plans are Free (€0/month), Pro (€19/month), and Agency (€49/month). Paid subscriptions will be billed monthly.
Is annual billing available?
Not during the initial beta launch. Annual plans may be introduced later.
How will paid subscriptions be managed?
Paid subscriptions will be managed through our billing provider's customer portal once paid checkout opens.
