A Supplier Changed Their Price and a Competitor Responded: What to Check Before Making Your Own Decision

A supplier changed the price, a competitor reacted, and your product listing is still running under the old terms. Reacting with an immediate price change is risky: a single signal doesn't tell you what actually happened to the product or the market.

What follows is an illustrative scenario, not a client case study. The specific prices, dates, stock levels, reasons for the changes, and the sequence of events need to be verified against the source data.

Why one signal isn't enough

A new figure from a supplier may refer to a different batch, package configuration, or order terms. A competitor may be running a discount or promotion, may be selling a different unit of the product, or may be working under different fulfillment terms. The price in your seller account and the price on the storefront may also refresh at different times.

Before changing your own price, check four sources: the supplier, competitors, the marketplace, and your own product.

1. Supplier data

Record the purchase price, the date you received the message, the SKU, model, size, color, package configuration, and delivery terms. Confirm whether the new figure applies to the current batch and whether there's a source that verifies the change.

The supplier's price is an input, not a ready-made recommendation for your storefront price. You need to compare it against your cost price, your minimum acceptable price, and current selling terms.

2. The competitor's offer

Compare more than just the number in the listing. Check the brand, model, specifications, unit of sale, package configuration, product availability, region or warehouse, discount, promotion, and the date of observation.

A matching title doesn't confirm that you're looking at a comparable product. A price per set and a price per single unit describe different offers, even when the listings look alike.

3. Marketplace mechanics

Check whether the price in your account matches the price on the storefront, whether any discounts or promotions apply, and when the data was last updated.

Different marketplaces give sellers access to price, specification, and stock data, but the way that data is displayed and refreshed can vary. On Yandex Market, a new price and updated stock information may appear with a delay. On Wildberries, the price a shopper sees can differ from the price the seller has set, because of discounts and marketplace terms.

A temporary discrepancy between your account and the storefront shouldn't automatically be read as a change in the market.

4. Your own product

Check the specifications and package configuration, the current price in your account and on the storefront, available stock, discount, participation in any promotion, region, warehouse, fulfillment model, minimum acceptable price, and the date of the last change.

How to document the check

For a single product, build a table with the following columns: source; date and time of observation; SKU or other identifier; price; discount or promotion; stock; specifications and package configuration; region or warehouse; confirmation status.

Enter the supplier's data, the competitor's data, your own listing, and the marketplace storefront as separate rows. Don't merge these values: the purchase price, the competitor's price, the price in your account, and the price to the shopper may all describe different terms.

Before changing the price, answer three questions:

1. Has the change itself been confirmed, or has it only been observed once?
2. Are the products and the selling terms comparable?
3. Is there a reason to change the price now, or should you wait for the data to refresh?

Key takeaway: a competitor's price change is, on its own, not a sufficient reason to change your own price immediately. First verify the source of the signal, the comparability of the products, and the selling terms.
