The short answer

Pricing and promotions in ecommerce are the decisions about a product’s everyday price and the temporary offers used to change demand. A sound framework sets credible reference prices, chooses each promotion for a specific objective, calculates the sales uplift needed to break even, limits depth and frequency, and protects price consistency across channels.

Price is the loudest message you send

Customers read price before they read copy. A price tells them where a product sits in the market, how confident the brand is in its quality and whether waiting might pay. That makes pricing a marketing decision as much as a finance one, and promotions the most frequently misused tool in ecommerce.

The trouble with promotions is that they work, in the short term. Revenue rises during the sale, the chart looks healthy and the next sale is planned. What the chart does not show is the margin given to customers who would have bought anyway, and the slow erosion of the full price’s credibility.

A discount is a loan against the credibility of your full price. Borrow rarely, and know the interest rate.

Set the everyday price first

Promotions only make sense against a stable everyday price. That price should reflect value to the customer, competitive alternatives and the cost structure, including shipping, payment fees, returns and acquisition. Our guide to pricing strategy covers methods; here we focus on how ecommerce changes the picture.

  • Visibility. Online prices are easy to compare across sites, marketplaces and quick-commerce apps.
  • Total cost. Shoppers judge price including shipping and COD fees, not the number on the product page.
  • Reference prices. Showing a struck-through price invites scrutiny; it must be a price the product genuinely sold at, in line with consumer protection rules.
  • Channel parity. Large gaps between your site and marketplaces teach customers where to buy.

Choose promotions by objective

Every promotion should have one primary objective, decided before the mechanics. Different objectives call for different tools, and using the wrong tool is the source of most promotional waste.

ObjectiveSuitable mechanicsAvoid
Acquire new customersFirst-order offer, sample or trial pack, bundle with a hero productSite-wide discounts that existing customers also take
Raise basket sizeFree-shipping threshold, tiered offers, bundlesPercentage discounts that reduce margin on every item
Clear stockTargeted markdowns on specific items, outlet sectionDiscounting the whole range to move a few products
Reactivate lapsed buyersPersonal offers to lapsed segmentsPublic codes that leak to coupon sites
Compete in peak eventsPlanned event pricing, exclusive packsUnplanned matching of every competitor move

The break-even question

Before running a discount, ask how much extra volume it must generate just to earn the same contribution as before. The answer is often surprising. Because a discount comes straight out of margin, a modest price cut can require a large increase in units to break even.

Break-even volume for a discount

Illustration only: defaults are invented. Use contribution after all variable costs.

Contribution per unit at full price

₹400

= price - varcost

Contribution per unit on promotion

₹200

If this is zero or negative, the promotion loses money on every unit.

= price * (1 - disc) - varcost

Required uplift in units to break even

100%

Extra volume needed just to stand still on contribution.

= (price - varcost) / (price * (1 - disc) - varcost) - 1

Defaults are illustrations. Use your own numbers. Nothing you enter leaves this page.

In the default illustration, a fifth off the price on a product with forty per cent contribution margin requires double the volume just to break even. And some of that volume is pulled forward from future weeks or comes from customers who would have paid full price. Our guide to ecommerce unit economics explains how to calculate contribution honestly.

Depth and frequency

Two dimensions decide whether promotions build or erode a brand: how deep they go and how often they run. Mapping your promotions on these axes shows the pattern customers are learning.

Brands drift towards the top-right quadrant one reasonable decision at a time. A fixed annual promotion calendar, agreed in advance and changed only with clear reason, is the simplest protection.

Non-discount promotions

Many promotions do not need to cut price at all. They change what the customer gets rather than what they pay, which protects the reference price and often costs less.

  • Gift with purchase. A sample or accessory that costs less than its perceived value.
  • Bundles. Products that work together, priced for value without discounting each item. See average order value.
  • Free shipping thresholds. Encourage larger baskets while removing a common objection.
  • Early access. Let loyal customers buy new launches first, rewarding them without margin loss.
  • Limited editions. Create urgency through scarcity rather than price.

Questions to weigh before approving an offer

Weights express relative importance in this framework, not measured data.

Psychological pricing, used with care

Price presentation shapes perception. Ending prices just below a round number, showing a per-unit or per-use price for larger packs, and anchoring a premium option beside a standard one are long-established retail practices. They work because they help shoppers make sense of value, not because they trick them.

The line to hold is honesty. Anchors must be real products customers can buy. Per-unit prices must be calculated consistently. Countdown timers must reflect genuine deadlines. Tactics that mislead may lift one sale and cost a customer, and in many markets they also breach consumer protection rules. See trust signals.

Promotions across channels

In India, marketplaces and quick-commerce apps run their own sale events and often expect brand participation. A brand that discounts heavily on a marketplace while holding full price on its own site sends conflicting signals and shifts customers to the cheaper route.

Agree rules before peak season: which products participate, at what depth, whether the brand site matches, and whether exclusive packs are used to avoid direct comparison. See marketplace marketing and festive sale marketing.

Measuring what a promotion really did

Promotion reports usually compare sale-period revenue with the previous period. That overstates the effect, because it ignores pull-forward (customers buying earlier than they would have), the dip afterwards, and the margin given to customers who would have bought anyway.

  • Compare contribution, not revenue, over a window that includes the weeks after the promotion.
  • Hold out a randomly chosen segment from targeted offers to measure incremental effect.
  • Track how many promotion buyers return later at full price.
  • Watch whether the share of full-price orders is falling over time.

Key takeaways

  1. 01Set a credible everyday price before designing any promotion.
  2. 02Give each promotion one objective and choose mechanics that fit it.
  3. 03Calculate the volume uplift needed to break even; it is often larger than expected.
  4. 04Keep promotions on the shallow or rare side; constant deep discounts make full price fictional.
  5. 05Measure promotions on incremental contribution, including pull-forward and the dip afterwards.

Frequently asked

How do I decide what discount to offer?
Start from the objective and the economics. Calculate contribution per unit at full price and at the proposed discount, then the volume uplift needed to break even. Choose the shallowest offer that achieves the objective, target it as narrowly as possible, and consider non-price alternatives such as bundles or gifts.
Are free shipping thresholds better than discounts?
Often, for raising basket size. A threshold removes a common objection and encourages customers to add items, while protecting product prices. Set the threshold just above your current typical order value and check that the extra items cover the shipping cost absorbed.
How often should an online store run sales?
There is no universal answer, but rarer is usually healthier. Plan an annual calendar around genuine occasions such as festive seasons, launches and clearance windows, and avoid unplanned additions. If customers routinely wait for sales, frequency is probably too high.
What are the rules on showing original and sale prices?
Consumer protection rules in many countries, including India, prohibit misleading price claims. A struck-through reference price should be one the product genuinely sold at. Rules vary by jurisdiction and change, so check current guidance and take legal advice for your markets.
How do I measure if a promotion worked?
Compare contribution, not revenue, over a period that includes the weeks after the promotion, to capture pull-forward and any dip. Where possible, hold out a random group from targeted offers to measure incremental effect, and track whether promotion buyers return at full price.
