Get Alerted the Moment a Supplier Changes Their Prices
An n8n workflow that periodically fetches your suppliers' price lists, compares them to the last known prices, and alerts you to any increases or drops with the exact delta — so cost creep never silently erodes your margins and you can renegotiate or re-price in time.

Frequently asked questions
Where do supplier prices come from?
A supplier API, a price-list URL, or a shared Google Sheet they update. The workflow reads the current prices and compares to a stored snapshot. Even suppliers who just email a spreadsheet can be covered by parsing that file into the same table.
Why alert on drops too, not just increases?
Price drops are opportunities — to lower your own prices competitively or improve margin. Both directions matter, so the alert reports any change over a small threshold and lets you decide what to do with it.
