Volume pricing looks simple and is where a lot of connectors quietly fail. The break table has to reach the storefront, the page has to show the whole ladder so a buyer can see what one more case is worth, and the cart has to re-price the moment a quantity crosses a break.
It also interacts with everything else. A customer on a contract price may or may not also receive volume breaks. A break may be defined on the line, across the order, or across a period. Whether it applies to the ordered quantity or to the shipped quantity matters when an order is split. Each of those is a different rule in the ERP, and each needs an answer before the connector is configured.
The usual failure mode is a storefront that shows the first-tier price to everybody and applies the correct price only in the ERP after the order lands. The buyer then receives an invoice that does not match what they were shown, which is the fastest way to send them back to the phone.
Why it decides a platform
Volume breaks are the most common form of B2B pricing after contract pricing, and the two frequently apply at once. A platform that handles either one alone but not both together will misprice a large share of orders.
Also called: tiered pricing, tier pricing, volume break, volume breaks, break quantity, quantity break, volume discount, quantity discount, tier price.
