How to Set Quantity Break Tiers: Tier Points, Discounts and Margin

Set quantity break tiers one step above what customers already buy, give each tier a discount you have checked against profit per order, and stop at two or three tiers. The first tier belongs at the quantity most orders fall just short of; the last at the largest quantity one customer can sensibly use. This guide covers how to read tier points from your order data, how deep each discount should go, a margin check with example numbers, which tier to highlight and how to word the offer.

Where should the tier points go?

Just above current behaviour. A tier at a quantity people already buy pays them for doing nothing new.

Export the orders for the product over a period long enough to cover a normal buying cycle, and count how many orders contain one unit, two, three, and four or more. Then read the shape:

• Nearly every order is a single unit. Put the first tier at two.
• A good share of orders already contain two. Start the break at three. A discount at two would mostly go to people who needed no persuading.
• The product has a natural pack. If it is used in pairs, by the month or by the box, set tiers at those quantities so the offer matches how it is consumed.

Check the reorder interval too. If customers come back roughly monthly, a three-unit tier sells three months of supply, which is reasonable. A twelve-unit tier on something that expires or goes stale is a tier nobody should take.

How many tiers should there be?

Two or three, on top of the single-unit price. Every tier is another row to read and another sum to do. With two or three rows the shopper compares and chooses; with five, the offer becomes a price list and the easy decision is to buy one.

How deep should each discount be?

Deep enough that the saving is worth noticing in money, shallow enough that every tier earns more per order than the tier below it.

A few rules that hold for most catalogues:

• Fund the discount from costs that do not scale. One parcel, one pick and one payment fee across several units is a real saving. Part of it can go to the customer.
• Make each step up bigger in money than the last. The percentage does not have to rise evenly, but the saving shown must clearly grow.
• Leave headroom. If the top tier already matches your deepest seasonal promotion, you have nothing left to offer in a sale, and the two may combine. Decide that on purpose; our guide to how discount combinations and stacking work on Shopify explains the settings.

How do you check the margin on each tier?

Work out profit per order at every tier, then compare it with what the customer would have done without the offer.

Say a store sells a bag of coffee for $18. As example figures, each bag costs $7 to produce and $1 to pick and pack, and a parcel costs $5 to ship whether it holds one bag or three.

• One bag at $18: costs $13, profit $5.
• Two bags at 10 percent off, $32.40: costs $21, profit $11.40.
• Three bags at 15 percent off, $45.90: costs $29, profit $16.90.

Each tier earns more than the one below, so the ladder is sound on paper. The second check is the one that gets skipped. A customer who would have bought two bags at full price anyway would have left $15 of profit; under the offer they leave $11.40. That $3.60 is the price of setting the first tier where people already buy, and it is why the tier points come from order data and not from habit.

If any tier earns less per order than the tier below it, the discount is too deep or the product does not have the margin for quantity breaks. The pillar guide to Shopify bundle types covers what to use on thin-margin products instead.

Which tier should be marked as most popular?

Highlight the tier you most want chosen and can best afford, which is usually the middle one. A highlighted middle tier gives an undecided shopper a default that is neither the minimum nor the maximum.

Keep the label honest. Use 'Most popular' only once your orders show it is the most chosen tier. Before that, 'Recommended' or 'Best value' says what you mean without claiming something you cannot show. If your widget lets you preselect a tier, make sure the quantity and the total are obvious on the button, so nobody adds two units believing they added one.

How should the offer be worded?

Quantity first, then the saving: 'Buy 2, save 10%'. The shopper reads what to do and what they get, in that order.

• Show the price per unit and the total for each tier, so nobody has to calculate.
• Use the same pattern on every row. Mixing 'save 10%' on one tier with '$8 off' on the next forces a comparison across formats.
• Keep the single-unit row visible at its normal price. It is the reference that makes the other rows read as savings.

The price on the product page must be the price at checkout, with no code to enter. Marka Bundles & Upsells includes quantity breaks as an offer type and applies the discount automatically at checkout through Shopify Functions.

A short checklist

1. Count orders by units per order before choosing any tier point.
2. Put the first tier one step above the most common quantity.
3. Limit the ladder to two or three tiers with clear gaps.
4. Calculate profit per order at each tier, including shipping and packing.
5. Compare each tier with what the buyer would have paid without the offer.
6. Word every tier the same way and show the per-unit price.
7. Review the tier mix after a full buying cycle, using the measures in our guide to bundle metrics.

Tiers are cheap to change and expensive to leave wrong, so treat the first ladder as a starting position and adjust it from real orders. When you are ready to publish one, Marka Bundles & Upsells lets you create the offer in the Shopify admin and preview it before it goes live.
