Pricing Strategy for Online Stores: From True Costs to Testing Price Changes

Price is one of the most influential decisions in a business, yet it is often set in the simplest way: look at competitors' prices, add a certain percentage on top of cost, then hope for the best. That approach is not wrong as a starting point, but it is rarely enough for an online store that wants to grow healthily.

In an online store, price has special characteristics. Buyers can compare dozens of sellers in seconds, prices can be changed instantly, and buyer behaviour data is available for analysis. The opportunity is large, but so are the risks: price wars that erode margin, discounts that make customers wait for promotions, or prices that do not reflect a product's real value.

This article covers how to think about price in a structured way: understanding true costs, choosing a pricing approach, building a tidy price structure, managing discounts, and testing changes safely. We give no benchmark figures because every business differs; what we give is a framework you can apply to your own products.

Summary

• Start from true costs, including the ones often forgotten
• Price reflects value in the buyer's eyes, not merely cost plus a percentage
• Build a consistent price structure so it is easy to understand and manage
• Use discounts as a tool with a clear purpose, not a habit
• Test price changes gradually and measure the impact on profit, not just sales

Start from true costs

Many online sellers calculate cost only from the purchase price of goods. In fact, there are other layers of cost that reduce profit on every order. If they are not counted, a price that looks profitable can turn out to be a loss.

• Cost of goods or production cost, including materials, labour, and packaging
• Shipping you bear and packing costs
• Payment fees and platform or marketplace commission
• Advertising and acquisition costs to get buyers
• Return costs, replacement of damaged goods, and unsold products
• Operating costs: rent, salaries, software, and storage
• Applicable taxes according to your business's rules

Calculate profit per product with all those layers, not just the difference between selling price and purchase price. The result is often surprising: a product that looks popular barely earns anything, while a product rarely noticed contributes the biggest profit.

Pricing approaches

There is no single correct approach for all products. Many stores combine several approaches according to the character of each product.

Cost-based

Price is set from cost plus the desired margin. Easy to calculate and ensures every sale covers costs, but ignores how much buyers are willing to pay. Suitable as a floor, not as the only consideration.

Competitor-based

Price follows the market. This approach is natural for uniform products that are easy to compare, but risks triggering a price war and makes you dependent on competitors' decisions. If your cost structure is heavier, following the lowest price can be a road to loss.

Value-based

Price is set from the benefit the buyer perceives: quality, convenience, guarantee, service, or brand image. This approach allows healthier margins if you can explain the value well. It requires understanding customers and honesty about what differentiates your product.

Understanding buyers' perception of value

Buyers rarely know your costs. They judge price from what they see: comparisons around it, reviews, packaging, clarity of information, and trust in the store. Two stores selling the same item can have different prices and both sell, because buyers value things beyond the item itself.

So improving perceived value is often more effective than lowering price. Clear photos, honest descriptions, reliable shipping, easily claimed guarantees, and responsive customer service all increase willingness to pay.

Study your customers. Are they price sensitive, or do they care more about speed and certainty? Short interviews, surveys, and purchase data patterns can give clues. Different segments may deserve different offers.

Building a tidy price structure

A random price structure makes management difficult and confuses buyers. Arrange it with logic that can be explained.

• Product tiers: basic, mid, and premium choices with clear differences between tiers
• Packages and bundles: combining complementary products at a more attractive price
• Wholesale or bulk pricing: tiered discounts by quantity for certain customers
• Subscription or periodic pricing: for products used continuously
• Segment pricing: for example business versus individual customers, with a transparent reason

Pay attention to ending digits. Prices that end in round numbers or numbers common in your market affect impressions. Some markets are used to prices ending in certain digits, while others consider them ordinary. Observe your market's habits and test before changing everything.

Maintain consistency across channels. If prices on the website, marketplace, and physical store differ greatly without a clear reason, customers will feel disadvantaged and look for the lowest price. If differences are necessary, for example because of platform commission, make sure the reason is reasonable and consciously managed.

Pricing new products

New products bring uncertainty: you do not yet know how large the demand is and how much buyers are willing to pay. Two classic approaches are penetration pricing, starting lower to seize market share quickly, and skimming pricing, starting higher to capture buyers most willing to pay and then lowering it gradually.

The choice depends on goals and the nature of the product. Penetration pricing makes sense if cost per unit falls with volume or if you want to build a customer base that will buy other products. Skimming suits products that are unique and have enthusiastic early buyers. Whatever the choice, plan how the price will evolve so early buyers do not feel disadvantaged.

For genuinely new products, start with a testable hypothesis and schedule a review after a few weeks. Early sales data, buyer questions, and reasons for cancellation are valuable sources of information on whether the price is right.

The anchoring effect and how to present prices

Buyers judge prices relatively. The first number they see becomes the reference for judging the next. So how options are presented affects decisions. When three packages are shown, the middle one often feels most reasonable when flanked by a simple option and a premium option.

Use this honestly. Showing a crossed out price that never actually applied, or creating fake options only to steer buyers, may work once but damages long term trust and may violate consumer protection rules. The aim is to help buyers weigh clearly, not to trap them.

Show prices in an easily comparable way: unit price for multiitem packs, a clear total including extra fees, and differences between tiers in simple language. Clear information reduces doubt, and buyers who do not doubt are more likely to complete the purchase.

Managing discounts and promotions

Discounts are a powerful tool but dangerous if used without purpose. Customers used to price cuts learn to wait, and the normal price starts to feel too expensive.

• Define the purpose of each promotion: clearing stock, attracting new customers, or encouraging repeat purchase
• Limit duration and quantity so it feels special and does not become a habit
• Calculate the impact on margin before launching, including if many take advantage of it
• Avoid stacking several discounts so the final price falls below cost
• Consider added value other than a price cut, such as gifts, free shipping, or extra service
• Measure results afterwards: the real additional sales and the effect on sales after the promotion ends

Remember that some sales during a promotion are merely purchases brought forward or purchases that would have happened at the normal price anyway. Judging a promotion only by the sales spike during that period can mislead. Also look at what happens in the weeks after.

The effect of shipping costs and extra fees

Buyers judge the total paid, not just the price of the goods. Shipping costs, service fees, or extra charges that appear at the end of the process are often the biggest reason carts are abandoned. So the price structure needs to be seen as one package.

There are several ways to handle it: build part of the shipping cost into the item price, offer free shipping above a certain spend, or show the total cost from the start. Each has consequences for margin and perception, so it needs testing on your products and customers.

Testing price changes safely

Changing prices without data is gambling. A wiser approach is a controlled experiment: change prices on some products or for some period, then compare the results with a comparison group.

1. 01Define a hypothesis: for example, raising the price of a certain product will not reduce sales meaningfully
2. 02Choose products or groups of buyers large enough to observe
3. 03Set success indicators: profit per product, not just unit count
4. 04Run long enough not to be affected by daily or seasonal variation
5. 05Compare with a comparison period or product, then decide
6. 06Record the results and the reasons so the learning is not lost

Be careful with consistency. If two customers see different prices for the same item without a clear reason, trust can be damaged when they compare. The safest experiments are done on products, time periods, or packages, not on different people for the same product.

When to raise prices

Many sellers fear raising prices because they worry about losing customers. Yet there are situations that clearly demand it: costs keep rising, demand exceeds stock, quality or service improves, or your price is far below the market without strategic reason.

• Communicate honestly and on time, especially to subscription or loyal customers
• Tie it to value: what they get or what has changed
• Consider small gradual increases rather than a big jump at once
• Prepare options for price sensitive customers, for example a simpler variant
• Monitor reactions, including questions and complaints, then adjust

Conversely, lowering the price as a spontaneous response to competitors is often not the best answer. First ask whether your customers are really switching because of price, or because of other factors such as availability, speed, and trust.

Prices on marketplaces and on your own website

Sellers selling across several channels face different cost structures. Marketplaces charge commission and service fees, but bring buyer traffic. Your own website takes no commission, but you bear the cost of attracting visitors and building trust.

Calculate margin per channel separately. A product that is profitable on your own website can be thin on a marketplace after commission, and vice versa. Many sellers adjust prices, packages, or product choices per channel to keep margins healthy, as long as the differences are reasonable and do not make loyal customers feel disadvantaged.

Also consider giving customers reasons to buy directly from your website, for example a points programme, exclusive packages, better after sales service, or more flexible delivery. That way you are not merely competing on price, but on the total value offered.

The role of systems and data in pricing

Good price decisions need reliable data: up to date cost per product, sales per channel, actual margin after all costs, and promotion results. If this data is scattered across spreadsheets and separate notes, decisions are slow and often miss.

A system connecting the online store, inventory, and finance lets you see real margin per product and per order, not estimates. Price rules, such as wholesale prices or special prices for customer groups, can also be managed centrally so there are no errors on each channel.

Bulk price changes also become safer. With approval flows and change history, you know who changed what and when, and can undo it if an unintended input error occurs.

Common mistakes

• Setting prices only by copying competitors without calculating your own costs
• Ignoring shipping, payment, and return costs in margin calculations
• Overdiscounting so customers wait for promotions
• Judging promotions only by a momentary sales spike
• Changing prices without recording and without measuring the impact
• Fearing to raise prices when costs have risen far

First steps you can start this week

1. 01Pick your twenty best selling products and calculate net margin with all cost layers
2. 02Flag products with thin or negative net margin and decide on action
3. 03Review the last three promotions: what was the real impact on profit and later sales
4. 04Choose one product for a small price change test with clear indicators
5. 05Set a regular price review schedule, for example monthly or quarterly

Closing

Pricing is not a one time decision but a learning process that keeps running. Markets change, costs change, and customers change. The winning store is not the one that is always cheapest, but the one that understands its costs, is honest about its value, and dares to test carefully.

Start by calculating real margin, tidy the price structure, and manage discounts as a tool with a purpose. With reliable data and measured experiments, price turns from a source of anxiety into one of the most dependable growth levers.
