Know when a rival cuts price in New Zealand, before your margin does

A rival's Friday markdown can sit unseen until Monday, by which time your Tradivo listing or online shelf has already lost the sale. 4pricing checks the listed prices of the stores you choose, shows the lowest price for each product, and gives a recommended price that you apply yourself.

Everything you need to track competitor prices in New Zealand

4pricing checks prices on the competitor shops you add by URL — for example The Warehouse, Noel Leeming, PB Tech, Kmart NZ, Mighty Ape or Briscoes — for the products you choose, from every hour upward. You get an alert on the first check that catches a change, the price history is kept, and an algorithm (not generative AI) calculates a recommended price. You decide what to change in your own shop.

Automatic price checks on the interval you set

  • Add competitor shops by product URL — The Warehouse, Noel Leeming, PB Tech, Kmart NZ, Mighty Ape or Briscoes are examples, not a fixed list
  • No manual site checking needed
  • An interval you set per product, from one hour upwards
  • Your entire catalog, regardless of size

An alert on the first check that catches a change

  • In-app inbox or webhook when a competitor changes price
  • Know within the interval you set, not the next day
  • Alerts per product or per category
  • Configure alert rules as needed

Algorithm-driven recommended price

  • Algorithm compares your price with the competitor prices you track
  • Suggests a competitive price: a calculation, not generative AI
  • Respects the minimum margin you set
  • You decide: you apply the price yourself, in your shop, after checking it

Stored competitor price history

  • Every competitor price change with exact timestamp
  • Trend chart per product per competitor
  • Spot one-time promotions vs. strategic price changes
  • Anticipate seasonal campaigns (Black Friday, Boxing Day sales)

Add products and competitor pages by URL

  • Paste the product URL from your shop and from each competitor
  • Any online shop can be added by its URL
  • You decide which product pages — yours and your competitors' — are watched
  • You can correct or remove a watched page at any time

Fully documented REST API

  • Read price data from your own systems
  • Signed webhook for alerts and approved prices; any link to your own systems is something you build yourself on the API
  • On-demand CSV export — automate it from your own systems via the API
  • Full documentation with code examples

Strategic repricing without cutting margin

  • Algorithm calculates the optimal price per product and strategy
  • Respects your minimum margin (cost floor)
  • 3 strategies: undercut, match median, margin over cost
  • You decide: you apply the price yourself, in your shop, after checking it

Alert when you lose the lowest price

  • An alert as soon as we detect you are no longer the cheapest among the shops you monitor
  • Separate alert when a competitor drops below your price
  • Recommended price to get back in front, without going under your margin floor
  • Your position against every monitored shop, product by product
Briefing and opportunities

Daily briefing and opportunities

On top of monitoring, 4pricing prepares a briefing every day: what moved at your competitors, where you can raise a price without losing your position, where your margin is thinning and what is worth doing first. Every finding comes with the evidence it was built from and, where there is a basis for it, an estimated monthly value.

What the daily briefing contains

  • Opportunities: products where you can raise the price, or competitors that ran out of stock
  • Margin risks: prices below cost or below the minimum margin you set
  • Category campaigns, price wars and aggressive discounts seen at competitors
  • Assortment gaps, from the brand or category lists you follow
  • You see it in the panel inbox; it reaches a webhook only if you switch it on and set the destination

Where the amounts come from

  • The monthly value is computed only from your own shop's sales, which you send through the API
  • Without sales we do not invent a number: you see “—”
  • Sometimes a “market estimate, low confidence” appears, labelled separately; it is never added to the sales-based figure
  • Amounts are indicative, not a profit guarantee

How your price changes

  • You see the recommended price and the reason for it; nothing is sent
  • You check the recommendation against your cost, your minimum margin and your market position
  • If the price has moved in the meantime, check again before you apply it
  • A recommendation is a proposal: the decision to change the price stays with you

Sales go in, approved prices come out

  • You send daily sales per product through the API, up to 2,000 rows per request
  • An approved price reaches your system through a signed webhook (price.apply) and you confirm after applying it
  • A recommendation becomes a price only when you apply it manually, in your system or shop
  • There are no ready-made connectors for other platforms

Your price changes only when you apply it manually, and the webhook goes only to the destination you set.

Price API and webhooksAPI documentation for developers

Use price data in your own systems

4pricing gives you the data through a REST API (with API keys), an alert webhook and a CSV or Excel export. There are no ready-made connectors for ERP, WMS or marketplaces: what happens with the data is built by your own team or developers.

REST API & webhook — price data for your own systems

All data collected by 4pricing is available through a documented REST API: current competitor price per product, complete price history and algorithm-driven recommended price.

The signed webhook sends an HTTP notification on alerts. 4pricing does not write prices into your shop or your ERP: you apply the recommended price yourself, manually. There are no ready-made connectors.

Add products by URL and export to CSV — ready in minutes

You add products by pasting the product-page URL, one link at a time. You decide which product pages — yours and your competitors' — are watched.

CSV or Excel export runs on demand, in one click from the dashboard, with the complete price history. If you need a fixed cadence, call the same export from the REST API and schedule it with your own cron.

PB Tech, Noel Leeming and other shops — your price position across monitored shops

4pricing tracks the price shown on PB Tech or Noel Leeming like any other shop on your list and places it next to the rest of your competitors on the same product. When a competitor undercuts you, or when you are no longer the cheapest among the monitored shops, the alert reaches you at the next check, together with the recommended price to get back in front.

You choose the shops: add any online shop by product URL — The Warehouse, Mighty Ape, JB Hi-Fi NZ or Trade Me are only examples — and set a different check interval per product. There are no ready-made connectors, and we do not guarantee that every shop can be read.

Price intelligence for every retail vertical

4pricing monitors competitors and calculates a recommended price for online retailers in New Zealand in electronics, appliances, beauty, sport, DIY and more. You add the shops to follow by product-page URL — PB Tech, Noel Leeming or The Warehouse, for example — and pick the check interval per product. We do not guarantee coverage of any particular shop.

Electronics and IT

Electronics and IT

Laptops, phones, PC components, peripherals — the categories where prices move fastest. Without automated monitoring, you find out a competitor cut its price only when your sales drop.

You set the interval per product: for this vertical we suggest hourly checks on your best sellers and a less frequent check on the rest of the catalogue.

Large and small appliances

Large and small appliances

Fridges, washing machines, vacuum cleaners, coffee machines — predictable promotional cycles and head-to-head competition between shops.

Stored price history shows whether a discount was real: you can see when a rival pushed the price up before Black Friday and when it came back down.

Beauty and personal care

Beauty and personal care

Categories with many sellers and variable margins. Following the same product at several sellers shows who really is cheapest once offers are counted.

For this vertical, picking the exact product page at each competitor is critical — same size, same pack — because cosmetics come in variants that are not always obvious from the title. You decide which product pages are watched.

Sports and fitness

Sports and fitness

Equipment, clothing and accessories with pronounced seasonality. Anticipating end-of-season price drops is critical for margin.

The stored price history shows the trend, so you know when post-season cuts begin and can react before your competitors do.

DIY and garden

DIY and garden

Tools, building materials, garden furniture — strong spring-summer seasonality creates windows for higher prices when demand is high.

4pricing shows you when competitors raise prices for the season, so you can do the same without losing your position. Off-season, an alert reaches you at the first check that catches a large drop.

Automotive and motorcycle

Automotive and motorcycle

Car parts, accessories, consumables — a fragmented market with many niche sellers. Following prices at online parts shops lets you position correctly on steady-demand items.

There are many part numbers and prices move slowly, so you can set a wider interval and save credits, while an alert at the first check that catches a change still reaches you.

Toys and children's products

Toys and children's products

Concentrated seasonality (Christmas, summer holidays) with heavy price pressure at peak. Short-interval checks decide, on the busiest days, whether the sale lands with you or with the rival.

During peak weeks a price can change several times a day. Hourly checks on seasonal products mean you see it first.

Books, stationery and office supplies

Books, stationery and office supplies

Stationery, books and office supplies sell in steady volume, with peaks around the start of the school year and the holiday season. Following prices lets you position correctly at those moments.

Outside campaign periods this vertical has the most stable prices — 4pricing alerts you only when a real move happens, without filling your inbox.

What it is

What is 4pricing.net

4pricing.net is a price tracker for New Zealand online retailers who want to know how their prices compare with their competitors. You decide which shops you follow — you add each one by product URL, for example The Warehouse, Noel Leeming, PB Tech or Kmart NZ — and how often each product is checked, depending on your plan. You get an alert at the first check that catches a competitor changing a price, plus a recommended price calculated by the algorithm — sharp enough to win the sale, without giving away your margin.

What you can do with 4pricing

  • Monitor competitor prices across the shops you choose yourself
  • Get an alert as soon as a check catches one of your monitored shops changing a price
  • Access the stored price history per product, per competitor
  • Get a recommended price calculated automatically by the 4pricing algorithm
  • Spot products where you are too expensive and losing sales
  • Spot products where you are too cheap and leaving margin on the table
  • Add products to your catalogue by pasting their page URLs

Advantages for New Zealand retailers

  • Find out at the interval you set, from one hour up, when a competitor changes a price
  • Stored price history helps you tell a real promotion from a fake one
  • The recommended price takes into account the minimum margin you set
  • An alert when you are no longer the cheapest among the shops you monitor
  • No manual data entry: you paste the page URLs and monitoring starts by itself
  • A documented REST API with API keys and an alert webhook for your own tools

Current limitations

We are upfront. Here is where 4pricing.net is not yet the right fit:

  • Every shop is added by product URL and we do not guarantee coverage of any particular retailer; on small sites, reading the price may need checking
  • Prices do not change on their own: a recommendation is applied after your approval
  • You set the frequency per product, from one hour up depending on your plan, but every check uses a credit, so a very short interval across the whole catalogue costs more
  • There are no ready-made connectors to shop platforms, marketplaces or accounting systems; you use the API or the webhook (exception: on shops built on 4buildsite an approved price is applied directly)

How it works (3 steps)

Add your products

Paste the links to the product pages, yours and your competitors', one by one.

Monitoring runs by itself

The system checks prices at the interval you set for each product, from one hour up, and sends an in-app inbox alert and a signed webhook call at the first check that catches a change.

Decide with the facts

Review the recommended price and the competitor history, then decide: approve the proposed price or apply it yourself, by hand.
