Shopify inventory clearance discounts should turn excess units into cash—not train every customer to wait for a sale. The safest approach is to identify genuinely slow-moving SKUs, set a sell-through target, and reward shoppers for taking multiple eligible units during a limited campaign.

A storewide percentage-off sale cannot distinguish healthy inventory from stock that is tying up cash and shelf space. A targeted volume offer can. For example, “Buy 2, save 10%; buy 4, save 18%” gives customers a reason to take more of the products you need to clear while leaving new releases and dependable sellers at full price.

What are Shopify inventory clearance discounts? They are targeted, time-limited offers that encourage shoppers to buy multiple units of aging or excess stock. Merchants choose eligible SKUs, set quantity tiers from a sell-through goal, protect a minimum contribution margin, and stop the campaign when it reaches its inventory target or deadline.

This guide focuses on the clearance decision: which SKUs belong in the campaign, how many units the offer should move, how to protect contribution margin, and when to end or change the promotion. For the mechanics of building a tier ladder, use our Shopify quantity breaks setup guide. For a deeper treatment of unit economics, see how to calculate Shopify discount tiers and profit margin.

Start with inventory age and sell-through—not a discount percentage

Do not begin with “How large should the discount be?” Begin with “Which inventory problem are we solving?”

Review each product at the variant level. A black medium shirt can sell quickly while the yellow extra-small version sits untouched. Combining them at the product level can hide the actual problem and cause you to discount the healthy variant.

Use at least four signals:

  • Inventory age: days since the units were received or became available for sale.
  • Sell-through rate: units sold during a period divided by units available during that period.
  • Weeks of cover: units currently on hand divided by average weekly unit sales.
  • Recent velocity: whether unit sales are stable, improving, or declining in the last 30 to 90 days.

No single threshold works for every catalog. A 90-day-old seasonal accessory might be urgent; a 90-day supply of an evergreen replacement part might be normal. Compare products with similar seasonality, replenishment cycles, and shelf lives.

A simple clearance watchlist

Create a weekly or monthly inventory-aging view with one row per SKU:

SKU Units on hand Age of oldest units 8-week unit sales Weeks of cover Gross margin Action
Candle-Cedar 180 142 days 36 40 68% Clearance candidate
Candle-Linen 72 31 days 64 9 67% Keep full price
Mug-Sage 95 118 days 12 63 54% Investigate, then clear
Tee-Black-M 44 28 days 78 5 61% Exclude

This view separates a real overstock problem from a temporary dip. Before discounting, also check whether poor product-page content, an unavailable popular variant, a merchandising error, or inaccurate inventory is suppressing sales.

Decide what “cleared” means before you launch

A clearance campaign needs a unit goal and a deadline. “Sell more” is too vague to evaluate.

Choose one of these targets:

  • Reduce the SKU to a specific residual quantity.
  • Lower weeks of cover to a healthy range.
  • Sell through a fixed percentage before the season ends.
  • Free a defined amount of cash or storage capacity.

Suppose you have 180 cedar candles, sell 4.5 per week, and want no more than 12 weeks of stock after a four-week campaign. Your desired residual inventory is about 54 units:

4.5 weekly units × 12 weeks = 54 units

Your campaign therefore needs to move roughly 126 units. That number should shape the offer. If the campaign attracts 30 orders, the average discounted order needs to contain just over four units to hit the goal. A two-unit-only offer is unlikely to be enough.

Keep the target realistic. A steep discount cannot fix a product with no demand, confusing positioning, or a quality problem. If shoppers do not want one unit, asking them to buy four may make the mismatch more obvious.

Select eligible SKUs without discounting your winners

The cleanest clearance offer uses a tightly controlled product or collection eligibility list.

Include SKUs that meet most of these conditions:

  • They have materially higher weeks of cover than comparable products.
  • Their recent sales velocity is flat or falling.
  • Their margin can support at least the first useful tier.
  • Customers have a credible reason to buy more than one.
  • The stock is interchangeable across flavors, colors, sizes, or gifting occasions.
  • Clearing it creates a real benefit, such as releasing cash, shelf space, or warehouse capacity.

Exclude:

  • New arrivals that have not had a fair selling window.
  • Consistent full-price sellers.
  • Low-stock variants that make the offer hard to fulfill.
  • Products with unusually high return, damage, or support rates.
  • Regulated, perishable, or date-sensitive goods whose rules require special handling.
  • Items already in another promotion unless the combined economics have been tested.

If shoppers can mix eligible products or variants to reach a tier, state that clearly. “Any 4 clearance candles” is more useful than a vague “Buy 4” label. Mixing can also reduce the resistance to purchasing several identical units.

Build Shopify inventory clearance discount tiers around surplus units

For inventory clearance, a tier should map to units you need to move—not merely copy the standard 5% / 10% / 15% pattern.

Start with three questions:

  1. How many units does a customer usually buy without a discount?
  2. How many units per discounted order are needed to reach the clearance target?
  3. At what quantity do shipping, pick-and-pack, or packaging costs change?

If customers normally buy one candle and the campaign requires about four units per order, a reasonable hypothesis could be:

Eligible quantity Discount Purpose
2–3 10% Create an attainable first step
4–5 18% Make the target basket compelling
6+ 22% Accelerate gifting or stock-up orders

Two or three meaningful tiers are usually enough. Too many steps make the offer harder to scan and can give away margin at quantities customers would have purchased anyway.

Check contribution dollars, not just gross-margin percentage

Use the same product and the same cost assumptions across tiers. Include product cost, payment fees, extra fulfillment expense, expected shipping subsidy, and a returns or damage allowance.

Assume a candle sells for $30. Product cost is $10 per unit, variable fulfillment is $1.50 per unit, payment cost is approximated at 3% of collected revenue, and the six-unit tier adds $6 of shipping subsidy.

Quantity Discount Revenue after discount Product + fulfillment cost Payment cost Shipping subsidy Contribution dollars
1 0% $30.00 $11.50 $0.90 $0 $17.60
2 10% $54.00 $23.00 $1.62 $0 $29.38
4 18% $98.40 $46.00 $2.95 $0 $49.45
6 22% $140.40 $69.00 $4.21 $6 $61.19

The contribution percentage falls as the discount grows, but total contribution dollars increase because more units leave in one order. Whether that trade is acceptable depends on the cost of holding the inventory and your cash-recovery goal.

Set a floor before launch. For example: every discounted order must produce at least $25 in contribution, and no tier may fall below a 35% contribution margin. If a proposed tier fails, lower the discount, raise the quantity, remove high-cost SKUs, or avoid subsidized shipping.

Do not count the product’s original retail value as recovered cash. The relevant comparison is what you can collect now, less the variable costs of fulfilling the order, versus the likely value and carrying cost of waiting.

Time-box the clearance offer

An open-ended clearance campaign becomes the reference price. Give the offer a start date, an end date, and an inventory-based stop rule.

Use an end condition such as:

  • Four weeks have elapsed.
  • The eligible collection reaches the residual-unit target.
  • A seasonal cutoff is reached.
  • Contribution per order falls below the campaign floor.

Make urgency factual. “Ends October 27” or “while eligible stock lasts” is clearer than a permanent countdown that resets. If the campaign reaches its inventory target early, end it instead of continuing to discount scarce units.

Avoid adding more eligible stock midway through the campaign without recalculating the target. That turns a controlled clearance event into a general sale and makes the results difficult to interpret.

Configure a targeted clearance campaign in Multiscount

After the SKU list and tiers have passed your checks, use Multiscount to turn the plan into a visible Shopify offer:

  1. Create a product-based volume discount.
  2. Select only the clearance products or collection.
  3. Add the approved quantity tiers in ascending order.
  4. Decide whether eligible variants or products can combine toward the threshold.
  5. Record the campaign start and end dates in your promotion calendar, then activate and deactivate the offer on schedule.
  6. Review combination settings for order, product, and shipping discounts.
  7. Display the offer near the product purchase controls and in the cart.
  8. Test quantities immediately below, at, and above each threshold.

Use customer-facing copy that connects the quantity with the saving: “Choose any 4 clearance candles and save 18%.” If exclusions or mixing rules matter, show them beside the offer rather than hiding them in a policy page.

Multiscount supports tiered volume offers, product eligibility rules, and storefront widgets, so the clearance logic and its presentation can stay aligned. Shopify applies discount combinations only when the relevant discounts are configured to combine, so test every intended product, order, and shipping combination. Install Multiscount from the Shopify App Store when you are ready to build the validated offer.

Test the failure cases before launch

Clearance campaigns often contain mixed carts, limited variants, and other promotions. Test more than the happy path.

Your checklist should include:

  • One unit below, exactly at, and one unit above every tier.
  • Mixed eligible variants and products.
  • Eligible and ineligible items in the same cart.
  • A quantity reduction after a tier has applied.
  • An out-of-stock eligible variant.
  • An existing discount code and automatic discount.
  • Free-shipping thresholds and express-shipping choices.
  • Subscription items, bundles, Markets, and POS where relevant.
  • Refunds and partial returns that leave the order below its original tier.

Confirm the final price in cart, checkout, the order record, confirmation messages, and refund workflow. For a fuller QA matrix, follow our guide to testing Shopify discounts before launch.

Review the campaign weekly

Track clearance progress at the SKU and tier level. A high campaign-level sell-through rate can still hide one untouched variant.

Monitor:

  • Units sold and remaining by eligible SKU.
  • Sell-through rate during the campaign.
  • Weeks of cover at current velocity.
  • Average eligible units per discounted order.
  • Share of orders reaching each tier.
  • Contribution dollars per order and in total.
  • Return, cancellation, and refund rates.
  • Full-price sales of related products.

Compare results with the goal you set before launch. Use our Shopify discount performance measurement guide to separate campaign lift from sales that may have happened anyway. If most orders stop at two units but the target requires four, improve the merchandising, allow more products to mix, or reconsider the middle tier. If shoppers buy four units without using the top tier, do not deepen the discount just to make the ladder look stronger.

At the deadline, choose one action for each remaining SKU: return it to full price, move it to a smaller final-sale campaign, bundle it with a complementary item, use it as a gift, transfer it to another channel, donate it, or write it down. Do not let an expired campaign drift indefinitely.

Every Shopify inventory clearance discount needs an exit plan

The best Shopify inventory clearance discounts are narrow, measurable, and temporary. They apply only to confirmed excess stock, ask customers to take a useful number of units, preserve a predetermined contribution floor, and stop when the inventory goal or deadline is reached.

That discipline protects healthy products from unnecessary markdowns and gives you a clean result to review: units cleared, cash recovered, contribution earned, and stock still requiring a different action.
