Competitor Price Monitoring & Stock Tracking Services
Know when the products you care about change price or availability. We collect comparable observations, preserve the product and variant context, and deliver a history your team can use.

Agree the fields that matter.
- Product identity
- Source product ID, URL, and identifiers used to match the agreed item.
- Variant and offer
- Size, color, pack quantity, seller, or condition when those distinctions affect comparison.
- Observed price
- The selected price type and currency, with shipping or fees recorded separately when included.
- Availability
- Observed in-stock, out-of-stock, or unknown status for the specific variant.
- Change history
- Current and previous comparable observations, first seen, and last successfully checked.
- Collection context
- Source URL, timestamp, and the location or delivery context used for the observation.
Compare the same product, not just a similar title
A lower displayed price can refer to a different pack size, a used item, another seller, or a different variant. We start with your product list and matching rules. Stable identifiers are preferred; ambiguous matches are held for review rather than silently merged.
A two-pack and a single item should not trigger a price-cut alert against each other. The delivery can retain the match method so your team can inspect why two records were compared.
Choose a schedule around the decision you need to make
Daily assortment research and time-sensitive restock monitoring have different requirements. We agree the refresh interval, tracked pages, and expected delivery before building. Faster polling changes collection volume, maintenance needs, and the practical limits of each source.
Collection time is an observation timestamp, not a promise that a price or stock status remains unchanged. Unknown fields and failed checks are kept distinct from actual product changes.
Turn observations into a usable feed or alert
Your scope can cover CSV or JSON deliveries, a price-history dataset, or notifications for agreed events. An alert should identify the product, changed field, previous value, current value, and observation time. Integrations into your own reporting or pricing system are scoped separately.
Pricing depends on the sources, products, variants, cadence, and delivery. Shopify, Amazon, and Google source pages show their current managed-service starting estimates. Multi-source matching and custom alerts need a written project quote.
What a useful record looks like.
| Same example variant | Earlier check | Later check |
|---|---|---|
| Trail Shirt · Blue / M | $39.50 · in stock | $35.00 · in stock |
| Trail Shirt · Blue / L | $39.50 · out of stock | $39.50 · in stock |
| Day Pack · Green | $64.00 · in stock | Unknown · check needs review |
Fictional comparison. The final row is a collection uncertainty, not a zero price, delisting, or confirmed stock change.

Common questions
Can we monitor several stores or marketplaces?
Yes, after reviewing each source and agreeing product matching and collection context. Different currencies, sellers, conditions, and delivery locations need consistent comparison rules.
Can you send restock or price-change alerts?
Alerts can be scoped around defined events and delivery channels. We agree thresholds, duplicate suppression, unknown-value handling, and what happens if a source fails to respond.
Does a missing page mean a product is out of stock?
No. Access failures, changed layouts, and incomplete responses are treated separately. We only label availability according to the agreed evidence and retain an unknown state when it cannot be established.
Do you automatically change our prices?
The standard scope collects and delivers observations. Repricing or write access to your systems is a separate integration, with its own rules and approval process.
