Competitive Pricing

Know the second a competitor changes a price

You pick the competitor PDPs, marketplace listings, and dealer pages that move your margin. The moment a price, Buy Box, or stock status changes, it's in your inbox or Slack.

Data Points Extracted & Validated

You're finding out about price drops from your own sales numbers

By the time a velocity SKU shows up soft in Monday's report, a competitor has been undercutting you for a week. The tools that promise alerts bury you in garbage matches and stale data, so you end up verifying prices by hand anyway.

  • A week of lost baskets: a rival drops a KVI on Tuesday and you catch it Friday, after the damage is already in your numbers.
  • Garbage matches: half the 'price changes' your repricer flags are the wrong SKU or a cached page, so you stop trusting the alerts.
  • Scrapers go dark quietly: a DIY scraper breaks on an anti-bot update four to six times a year and just stops returning data, with no error.
  • Google Alerts can't see it: storefront and Buy Box prices live behind JavaScript, so keyword alerts never fire on a price change at all.

How it works

1

Point us at the pages that set your price

Drop in the exact competitor PDPs for your KVIs and velocity SKUs, the marketplace listings you track for the Buy Box, and the dealer sites you police for MAP.

Add a whole competitor set in one paste.

2

We watch the price, not the keyword

Our agent loads each page the way a shopper does and checks the live price, Buy Box owner, seller, and stock status on the cadence you set.

Works on JavaScript storefronts scrapers choke on.

3

A human verifies before you're pinged

Before any alert leaves the building, a person confirms the change is real and not a cached page or a bad match, then sends it to your inbox or Slack.

No false 'price drop' at 2 a.m.

Catch undercuts while the window's open

You hear about a price cut in minutes, not on Monday, so you can reprice or hold before you bleed baskets.

MAP violations with a timestamp

When an authorized dealer posts below MAP, you get the page and the time it changed, so the violation notice goes out the same day.

Buy Box and stock-out signals

Know the moment the Buy Box flips to a third-party seller or a competitor goes out of stock, which is your opening to move price.

No scraper to babysit

When a site changes its anti-bot setup, we fix the watch on our side. You don't wake up to an empty feed.

What pricing teams point us at

  • A rival's PDP for your top KVI flips from $89.99 to $79.99, and you're pinged before your velocity report is.
  • The Buy Box on your hero SKU changes hands to a third-party seller undercutting you by $4.
  • An authorized dealer posts your product below MAP, so you send the violation notice same day.
  • A competitor's clearance page lists your closest match as out of stock, opening room to hold price.
  • Google Shopping shows three sellers in your set dropping under your price-index threshold overnight.

Questions people ask

Every change is checked by a person before it reaches you. The AI flags that a price or Buy Box moved; a human confirms it's the right SKU on a live page, not a cached one or a bad match, then sends it. That's the part repricers and scrapers skip.

Yes. We load the page the way a shopper's browser does, so we read prices that keyword tools and most scrapers can't see. If a page needs specific steps to reach the price, tell us and we'll set it up.

Those are databases you log into and query on their schedule. We watch the exact pages you choose and push you the change the moment it happens, with a human check, so you're not the one refreshing PDPs.

We notice the watch broke and fix it on our end, usually before you'd see a gap. You don't maintain anything, and you won't get a silently empty feed like a DIY scraper gives you.
