Price Tiers
Quantity ranges and unit quantity windows are already part of the pricing-rule model, which is how tiered and volume-based pricing is represented today.

How it works in the app
PricingRule is a substantial domain model. Rules can target products, templates, brands, suppliers, categories, customer groups, customers, product groups, currencies, units, and date windows, with fixed prices, markup, discount amounts, and discount percentages.
Concrete price rows are stored separately in PricingRulePrice, which is why the current implementation supports real B2B segmentation and timed pricing rather than a single flat discount field.
