Competitor price monitoring and price history for online shops

4pricing compares the prices of product pages you choose and builds their price history from successful checks. Add your product and competitor URLs, group equivalent offers, and review price changes and alerts in the panel. Checks run on a schedule within your plan limits; approved price recommendations reach your store only through a configured destination.

Overview

What 4pricing does for your prices

4pricing reads the public product pages you give it, keeps what it finds and turns it into alerts, a history and a recommended price. Start with one public product URL and confirm that its price is read correctly.

Price history and alerts (Romanian) · API and webhook overview · Plans and check intervals (Romanian)

You decide what is watched

You paste the URL of each product page to follow: your own listings and the listings of rivals. 4pricing can suggest candidate pages for a product by searching the retailers by name, but nothing is added until you accept it, and nothing is matched automatically by EAN or by a product feed.

Checks on your schedule

Each monitored page is read again at an interval you set, within the limit of your plan. Every check uses credits, so a short interval over the whole catalogue costs more than a short interval on the few products that matter.

Alerts when a rival moves

You set alert rules, and you are told when a competitor goes below your price or when you stop being the cheapest on a product you follow. Alerts appear in the in-app inbox; a webhook alert leaves only after you enter a URL.

A recommended price, by calculation

For each product group 4pricing proposes a price with one of three strategies: below the cheapest competitor by a percentage you set, level with the competitors' median, or your cost plus a margin. It respects your minimum margin when you have entered your cost, applies your rounding rule, and shows a verdict for the group. It is arithmetic, not generative AI.

A price history you can read

History starts when you add a product and a check succeeds. Each saved price has a timestamp; there is no earlier history to import from a shop. A missed check leaves a gap, and a chart cannot show every price between checks.

A daily briefing

The panel prepares a daily briefing of what moved: products where you could raise the price, competitors that went out of stock, margins that are thinning. It is shown in the panel and goes out by webhook only if you switch that on.

Process

From the first link to an approved price

  1. Add your pages and your rivals' pages

    Paste the product URLs. Mark which products are yours and group them with the competitor pages you want them compared against.

  2. Set the interval and the margin

    Choose how often the pages are read and the minimum margin the recommendation must respect.

  3. Watch the alerts and the history

    When a competitor changes a price you see it in the panel with the earlier prices next to it.

  4. Approve the price that suits you

    A recommendation changes nothing by itself. When you approve it, the price is handed to your own system through a signed webhook, written directly if your shop runs on 4buildsite, or stored in 4pricing if the price was entered by hand or sent through the API.

Who it is for

Compare the offers that matter to your shop

Shops comparing equivalent offers

Choose the same model, variant and pack size before grouping offers. The recorded price is what the public page exposes to the reader; delivery charges, account-specific offers and currency differences can make two offers unsuitable for a direct comparison. Test a product URL before building your list.

Sellers on a marketplace

On a marketplace several sellers can list the same product, and shoppers can compare their prices. You add your listing and your competitors' listings by URL and 4pricing follows the price of each page. It does not identify individual sellers inside a listing.

Teams with their own systems

A documented REST API with API keys lets your developer read prices, history, opportunities and the briefing, and send your daily sales. Approved prices reach your own system through a signed price.apply webhook that you confirm after applying. There are no ready-made connectors for ERP, WMS, e-commerce platforms or marketplaces.

Before you start

What to know before you start

  • The estimated value of an opportunity is computed only from the daily sales you send through the API. It needs about a week of sales data; without it you see a dash, not an invented figure. A separately labelled low-confidence market estimate may appear instead and is never added to the sales-based figure.
  • Prices are never changed without your approval: a recommendation becomes an action only after you approve it.
  • If your price changed since the recommendation was calculated, the action is refused and nothing is written.
  • Amounts shown by the app are indicative; they are not a promise of profit.

Questions about price comparison and history

Short answers about what 4pricing does today.

  1. Which product prices can I compare?

    Add public product URLs and group equivalent offers yourself. A page must expose readable price data; blocked pages, login-only prices and some JavaScript pages may not work. Coverage of a particular shop is not guaranteed. This is a monitoring tool for the pages you select, rather than a catalogue of every offer on the web.

  2. Does 4pricing find the same product at my competitors by itself?

    It can suggest candidate pages from a name search, which you accept or ignore. Nothing is added or matched automatically, and there is no matching by EAN or product feed.

  3. Does it change the prices in my shop?

    Not by itself. A recommendation is only a proposal. When you approve it, the price is sent to your own system through a signed webhook, which you confirm after applying it; only shops built on 4buildsite receive the price directly. If your price was entered by hand or sent through the API, it is stored inside 4pricing.

  4. Can it connect to my ERP or store platform?

    There are no ready-made connectors. What exists is a documented REST API with API keys, a signed webhook for alerts and data export, so your developer can build the link on your side.

  5. Can I see price history from before I added a product?

    No. History starts with the first successful check after adding the URL. A recorded price is an observation at a specific time, not a record of every price the shop displayed. Alerts appear after a check detects your configured condition; email, SMS and WhatsApp delivery are unavailable today.

  6. How much does it cost?

    The table on this page shows the current monthly prices in euro and each plan's monitored-page, competitor-site and check-interval limits. Reading a shop page consumes credits. Check the pricing page and checkout for the plan, credit allowance and billing conditions that apply to your account.
