Why
A hundred off costs less to supply than one, whoever orders it.
What
A pricing rule holds quantity breaks for every customer on one scope.
How
Open /app/catalog?tab=pricing and choose New rule under Pricing rules; rules are for admins and owners.

Create a rule

  1. Step 1.

    Give it a Name, such as Volume discount, and pick the Scope (product, category, schema or service; a configurator rule reaches no line today) and what it Applies to.

  2. Step 2.

    Leave Starts and Ends empty for always on, or set the dates it runs between.

  3. Step 3.

    Under Tiers, enter a Minimum quantity and either a % discount or a fixed price. Choose Add tier for each further break.

  4. Step 4.

    Keep Active ticked and choose Save rule.

How a tier applies

  • The line takes the tier with the highest minimum quantity it reaches. Below the first tier, the rule does nothing.
  • A percentage discounts the price after any percentage special price. A fixed price is the unit price at that quantity.
  • Only the most specific scope's rules are considered, even when none of their tiers is reached, and only one rule applies: on a tie, the lowest price.
  • Tiers are stored in ascending order, whatever order they were typed in.

What the checks refuse

MistakeMessage
No tiersAdd at least one quantity break.
A quantity of zero or a fractionBreak 1: the quantity must be a whole number of 1 or more.
A discount over 100%Break 1: a discount is between 0% and 100%.
Two tiers on one quantityTwo breaks both start at 10. Each one needs its own quantity.
An end before the startThe end date is before the start date.

Where the ladder shows

A product line in the quote editor shows its Volume price ladder under How this price was calculated: only the quantities that beat the price for one. Tick Show volume price breaks on a quote to print the ladder on the PDF.
