What Is Dynamic Pricing? Repricing Strategies

Rules or AI? A guide to automatically updating your price while protecting your profit margin

Dynamic pricing is a strategy that automatically changes a product's price based on demand, competitor moves, and stock status. While Amazon makes roughly 2.5 million price updates a day globally, on Trendyol price bots typically scan competitor prices every 30 minutes. In this guide, we cover rule-based and AI-powered repricing, floor/ceiling price logic, and BuyBox protection from a seller's perspective.

Quick answer

Dynamic pricing is a model where a product's price automatically changes based on demand, stock levels, and competitor moves. On Trendyol, price bots typically scan competitor prices every 30 minutes and update your price within the floor/ceiling range you set — so your profit margin stays protected without manual intervention.

Summary: what you need to know

  • Dynamic pricing is a system that updates prices hourly or even by the minute based on demand, competitor, and stock data instead of keeping a fixed price.
  • Rule-based repricing works with simple if-then logic like 'stay 1 TL cheaper than the competitor'; AI-powered repricing performs demand forecasting and margin optimization.
  • A price bot that runs without a floor price (minimum price) can put you into loss-making sales — a minimum profit margin is mandatory for every barcode.
  • BuyBox isn't won by the lowest price alone — delivery time, stock availability, seller rating, and price consistency are evaluated together.
  • Trendyol commission rates in 2026 vary by category, subcategory, brand, and seller level (roughly 5-10% in electronics); repricing decisions must factor in this rate.
  • In 2026 the Turkish Competition Authority is investigating Amazon, Hepsiburada, and Trendyol over automated pricing algorithms; repricing itself is legal, but price-fixing agreements with competitors are not.

What Is Dynamic Pricing? Concrete Examples

Dynamic pricing is a pricing model in which a product's price doesn't stay fixed but changes automatically based on demand intensity, stock levels, seasonality, and competitor moves. Fluctuations in airline ticket and hotel prices are the best-known example; the same logic applies in e-commerce. According to a 2025-2026 analysis from Wharton Business School, Amazon updates prices roughly 2.5 million times a day globally, and the average product's price can change every 10 minutes. On Trendyol, Hepsiburada, and Amazon Turkey, price bots working on similar logic continuously scan competitor prices and update yours according to the rules you set.

The opposite is static/fixed pricing: you set the price manually and it stays the same even as the market changes. As of 2026, dynamic pricing has spread widely across retail, fast-moving consumer goods, fashion e-commerce, and even event ticketing; AI and real-time data streams have accelerated this spread.

Rule-Based or AI-Powered? Two Repricing Approaches

Repricing software works on two main logics. In a rule-based system, you define simple if-then rules like 'stay X TL cheaper than the competitor' or 'stay Y TL above the lowest price'; the system applies these rules to the letter. In an AI-powered system, the algorithm analyzes historical sales data, demand elasticity, and competitor behavior patterns to suggest a price that both wins the BuyBox and protects your profit margin. Most tools like PriceRest, Sentos, Buyboxlist, and Sopyo now offer both modes. Ecomiro's AI Price Suggestion module automates this decision for you, based on your product-level margin target.

Criterion Rule-Based Repricing AI-Powered Repricing
Logic Simple if-then rules (e.g., stay 1 TL cheaper than competitor) Demand forecasting + margin optimization
Speed/Frequency Typically scans every 30 minutes Near real-time, continuous learning
Best-fit category Standard products with high price sensitivity Highly competitive, high-volume categories
Risk Triggers price wars if applied blindly Depends on setup and data quality
Profit margin control Manually defined floor/ceiling Automatic, via dynamic target margin

How Do You Set Up a Price Bot on Trendyol?

To set up a price bot on Trendyol, first decide which barcodes will be included in dynamic pricing — it's safer to select highly competitive, low-margin products rather than your entire catalog. Next, define a floor (minimum) and ceiling (maximum) price for each product, then set your competitor scan frequency (the market standard is roughly every 30 minutes). In the final step, you choose and activate either a rule or an AI model, and closely monitor price movements for the first few days. Ecomiro's Buybox Tracking module lets you manage this setup store by store from a single screen, so you don't have to navigate separate panels and manually scan competitors.

  • 1. Select products — Prioritize SKUs with heavy competition and low margins.
  • 2. Define floor/ceiling — Set the minimum profit margin and maximum price for each barcode.
  • 3. Choose competitor scan frequency — The market standard is roughly 30 minutes; fast-moving categories can be scanned more often.
  • 4. Choose a rule or AI model — Decide between simple if-then logic or margin-optimized AI.
  • 5. Monitor and adjust — Check daily for the first 2 weeks to catch margin deviations early.

Protecting Your Profit Margin with Floor/Ceiling Prices

The biggest risk with a price bot is leaving it without a defined floor price. While the system tracks the competitor, you can end up selling at a loss without realizing it — especially for products with high shipping and commission costs, this can turn into serious losses within just a few days. The right setup is to set a floor for each barcode that says 'never go below this price' — and that floor must include the commission rate, shipping cost, and your target net profit. On Trendyol, commission in the electronics category ranges roughly 5-10% in 2026, and 9-10% for white goods; these rates must be factored into the floor price calculation, otherwise a sale you think is 'profitable' may actually record a loss.

Repricing without a floor price can quickly spiral into a price war in categories where competitors use the same system — everyone ends up following everyone else and margins approach zero. Always keep the floor price above the sum of commission + shipping + target profit.

How Do You Set Prices to Win the BuyBox?

The BuyBox isn't won by the lowest price alone; marketplaces like Trendyol and Hepsiburada evaluate delivery time, stock continuity, seller rating, and cancellation/return rate alongside price. That's why you should check your other metrics before lowering your price — a store with a low rating may not win the BuyBox even with the cheapest price. Smart pricing systems therefore use not just the competitor's price but also their stock status and delivery performance as data. Ecomiro's Buybox Tracking module shows in real time who's ahead on which product and by how many TL, so you can see when and how much you need to move your price.

Avoiding Price Wars and 2026 Legal Boundaries

Automated pricing is legal — updating your own price with your own data is not a crime. However, in 2026 the Turkish Competition Authority opened an investigation into Amazon Turkey, Hepsiburada, and Trendyol over automated pricing algorithms; the real risk is that algorithms can lead to indirect price-fixing with competitors (algorithmic collusion). The practical precaution on your end is this: limit repricing to your own cost and margin data — 'track' competitor prices, don't 'collude' on them. To avoid a price war, prefer a target-margin-focused strategy instead of chasing the lowest price; this is the second most common approach in the market and it protects sustainable profitability.

The lowest-price strategy only works for standard (unbranded) products with high price sensitivity; for branded or niche products, target-margin-focused repricing delivers more sustainable results.

There's no single official table in 2026; the rate varies by category, subcategory, brand, and seller level (1-5). For example, mobile phones carry roughly 5-6% commission, computers/tablets 7-9%, and white goods 9-10%, VAT included.

Yes, most repricing tools like PriceRest, Sentos, Buyboxlist, and Sopyo run on a monthly subscription model; the fee typically depends on the number of SKUs tracked. Ecomiro's Buybox Tracking and AI Price Suggestion modules offer this tracking right within your existing panel.

The floor price (minimum price) defined for each barcode is set to cover commission + shipping + your target net profit; the bot never goes below this floor. The ceiling price also prevents the price from rising unnecessarily and losing sales.
