Sales dropped. Now find out why, not what it might be.

In practice it is almost always one of six things: you lost the Featured Offer to a competing offer, you went out of stock or low on inventory, your price moved relative to the market, advertising changed — budget exhausted, campaign paused, bids cut, a listing problem suppressed visibility, or demand genuinely shifted. Each leaves a different fingerprint in your own data, which is why guessing is slower than checking.

Look at sessions and conversion separately from orders. If traffic held but orders fell on specific ASINs, suspect Featured Offer loss or price position. If traffic itself fell, look at advertising and listing visibility first. A tool with authorized access can compare both sides on the same ASINs rather than leaving you to reconcile two reports.

It can do the evidence-gathering, which is the slow part. With Vendooly connected, the assistant queries your authorized sales, inventory, pricing, Buy Box and Sponsored Products data, compares the affected period against the previous one, and reports which of the likely causes the numbers actually support. The interpretation and any corrective action remain yours.

Vendooly keeps a per-company analytics store with daily facts for sales, inventory, Buy Box, campaigns and keywords, so period-over-period comparison does not depend on re-pulling reports each time. Live API data is used when the current state matters, such as checking present stock or Buy Box status.

Order the causes by reversibility and cost. Restocking and un-pausing campaigns restore sales quickly and cheaply. Repricing works but costs margin, so do it after ruling out the free fixes. Listing and account-health issues can take days to resolve, so start them early even if they are not the main cause.
