Even more so than with other areas of e-commerce, the vocabulary of custom pricing, wholesale pricing and B2B pricing can feel like learning a second language. Customer tags, tiered pricing, quantity breaks, draft orders, net terms. The terminology matters because each word describes a specific mechanism that determines who sees what price and when. This glossary is just our way of lending a helping hand. It defines the essential terms for Shopify merchants navigating wholesale operations, B2B sales, VIP pricing programs, and volume discount strategies.
