See [Pricing presets](/docs/20260301/product-modules/products/concepts/products#pricing-presets-how-you-charge). ## B ### Billable metric A measurable quantity that Zenskar calculates from usage events, such as the number of API calls in a month. See [Metered usage](/docs/20260301/product-modules/products/concepts/products#metered-usage). ## C ### Combination A set of dimension values that has exactly one value for each dimension. See [Dimensions: what prices vary by](/docs/20260301/pricing-models/concepts/dimensional#dimensions-what-prices-vary-by). ### Combination price The price, with its own pricing model, that the dimensional pricing model charges for one combination. See [Combination prices: a price for each combination](/docs/20260301/pricing-models/concepts/dimensional#combination-prices-a-price-for-each-combination). ### Credits product subtype The subtype of products that provide credits or units of a custom currency, such as \$100 in platform credits. See [Credits product subtype](/docs/20260301/product-modules/products/concepts/products#credits-product-subtype). ## D ### Default pricing preset The pricing preset that Zenskar marks as the default for a product in one currency. See [Pricing presets](/docs/20260301/product-modules/products/concepts/products#pricing-presets-how-you-charge). ### Dimension A category by which the dimensional pricing model splits the quantity and sets separate prices. See [Dimensions: what prices vary by](/docs/20260301/pricing-models/concepts/dimensional#dimensions-what-prices-vary-by). ### Dimension value One of the values that a dimension can take. See [Dimensions: what prices vary by](/docs/20260301/pricing-models/concepts/dimensional#dimensions-what-prices-vary-by). ### Dimensional pricing model The [pricing model](/docs/20260301/product-modules/products/glossary#pricing-model) that splits the [quantity](/docs/20260301/product-modules/contracts/glossary#quantity) by [combinations of dimension values](/docs/20260301/pricing-models/concepts/dimensional#dimensions-what-prices-vary-by) and charges each combination with its own price. See [Dimensional pricing model: a price for each combination](/docs/20260301/pricing-models/concepts/dimensional#dimensional-pricing-model-a-price-for-each-combination). ## E ### Exclusive tier boundary The tier boundary that moves a quantity equal to the upper limit of a tier to the next tier. See [Tier boundary: where an upper limit falls](/docs/20260301/pricing-models/concepts/volume#tier-boundary-where-an-upper-limit-falls). ## F ### Fallback price The price, with its own pricing model, that the dimensional pricing model charges for the quantity that matches no combination price. See [Fallback price: the price for everything else](/docs/20260301/pricing-models/concepts/dimensional#fallback-price-the-price-for-everything-else). ### Inclusive tier boundary The tier boundary that keeps a quantity equal to the upper limit of a tier in that tier. See [Tier boundary: where an upper limit falls](/docs/20260301/pricing-models/concepts/volume#tier-boundary-where-an-upper-limit-falls). ## M ### Metered usage Usage that a billable metric measures for a pricing preset. See [Metered usage](/docs/20260301/product-modules/products/concepts/products#metered-usage). ## O ### On-demand quantity strategy A quantity strategy that treats each measured use as a separate consumption at the moment it occurs. See [Metered usage](/docs/20260301/product-modules/products/concepts/products#metered-usage). ### On/off product subtype The subtype of services that are either enabled or disabled, such as priority support. See [On/off product subtype](/docs/20260301/product-modules/products/concepts/products#onoff-product-subtype). ## P ### Partial-period handling The rule that decides how Zenskar charges, under the recurring quantity strategy, for a quantity that starts partway through a period: in proportion to the time used, or in full. See [Metered usage](/docs/20260301/product-modules/products/concepts/products#metered-usage). ### Per-unit pricing model The [pricing model](/docs/20260301/product-modules/products/glossary#pricing-model) that charges the same price for every unit. See [Per-unit pricing model: the same price for every unit](/docs/20260301/pricing-models/concepts/per-unit#per-unit-pricing-model-the-same-price-for-every-unit). ### Percent pricing model The [pricing model](/docs/20260301/product-modules/products/glossary#pricing-model) that charges a percentage of the quantity. See [Percent pricing model: a share of an amount](/docs/20260301/pricing-models/concepts/percent#percent-pricing-model-a-share-of-an-amount). ### Period ratio The length of a billing period divided by the length of its pricing period. See [Period-of-time products: a price for each pricing period](/docs/20260301/pricing-models/concepts/per-unit#period-of-time-products-a-price-for-each-pricing-period). ### Period-of-time product type The type of products that the customer consumes over a period of time, such as a seat for a month. See [Period-of-time product type](/docs/20260301/product-modules/products/concepts/products#period-of-time-product-type). ### Point-in-time product type The type of products that the customer consumes at one moment, such as an API call or a generated report. See [Point-in-time product type](/docs/20260301/product-modules/products/concepts/products#point-in-time-product-type). ### Pricing model The method that a pricing preset uses to calculate an amount from a quantity. See [Pricing models: how an amount is calculated](/docs/20260301/pricing-models/concepts/pricing-models#pricing-models-how-an-amount-is-calculated). ### Pricing period The length of time that the amount of a pricing preset covers, such as one month. See [Pricing presets](/docs/20260301/product-modules/products/concepts/products#pricing-presets-how-you-charge). ### Pricing preset A reusable way to charge for a product in one currency. A product can have several pricing presets, but a contract calculates charges for the product with only one of them at a time. See [Pricing presets](/docs/20260301/product-modules/products/concepts/products#pricing-presets-how-you-charge). ### Pricing-preset ID The identifier that Zenskar assigns to a pricing preset when you create it. See [Pricing presets](/docs/20260301/product-modules/products/concepts/products#pricing-presets-how-you-charge). ### Product A good or service that you sell, such as a software seat or an API call. A product describes what you sell, not what it costs. See [Products: what you sell](/docs/20260301/product-modules/products/concepts/products#products-what-you-sell). ### Product ID The identifier that Zenskar assigns to a product when you create it. See [Products: what you sell](/docs/20260301/product-modules/products/concepts/products#products-what-you-sell). ### Product status The lifecycle state of a product: active, inactive, or archived. See [Products: what you sell](/docs/20260301/product-modules/products/concepts/products#products-what-you-sell). ### Product subtype The classification of a product by how its usage is measured. See [Product subtypes](/docs/20260301/product-modules/products/concepts/products#product-subtypes-how-usage-is-measured). ### Product type The classification of a product by when the customer consumes it: at one moment, or over a period of time. See [Product types](/docs/20260301/product-modules/products/concepts/products#product-types-when-consumption-happens). ## Q ### Quantity product subtype The subtype of products whose usage is measured as a number of units, such as 100 API calls or 5 seats. See [Quantity product subtype](/docs/20260301/product-modules/products/concepts/products#quantity-product-subtype). ### Quantity strategy The rule that decides how Zenskar treats the measured quantity of a pricing preset: as separate consumptions that occur over time, or as a standing allocation that lasts until it changes. See [Metered usage](/docs/20260301/product-modules/products/concepts/products#metered-usage). ## R ### Recurring quantity strategy A quantity strategy that treats the measured quantity as an allocation that stays in place until it changes, such as a number of seats. See [Metered usage](/docs/20260301/product-modules/products/concepts/products#metered-usage). ## S ### SKU An identifier that you assign to a product to track it in your inventory or in external systems. See [Products: what you sell](/docs/20260301/product-modules/products/concepts/products#products-what-you-sell). ## T ### Tier A range of quantity that has its own price per unit. See [Tiers: ranges of quantity](/docs/20260301/pricing-models/concepts/pricing-models#tiers-ranges-of-quantity). ### Tier boundary The setting that decides whether a quantity equal to the upper limit of a tier belongs to that tier or to the next tier. See [Tier boundary: where an upper limit falls](/docs/20260301/pricing-models/concepts/volume#tier-boundary-where-an-upper-limit-falls). ### Tier-reset period The length of time after which the quantity counted against the tiers starts again from 0. See [Tier-reset period: when the count starts again](/docs/20260301/pricing-models/concepts/pricing-models#tier-reset-period-when-the-count-starts-again). ### Tiered pricing model The [pricing model](/docs/20260301/product-modules/products/glossary#pricing-model) that charges each part of the quantity the price per unit of the tier that the part falls in. See [Tiered pricing model: a price for each tier](/docs/20260301/pricing-models/concepts/tiered#tiered-pricing-model-a-price-for-each-tier). ## U ### Uncovered combination A combination that has no combination price. See [Combination prices: a price for each combination](/docs/20260301/pricing-models/concepts/dimensional#combination-prices-a-price-for-each-combination). ### Unit label The name of the unit in which a product is measured, such as seat or API call, in a singular form and a plural form. See [Products: what you sell](/docs/20260301/product-modules/products/concepts/products#products-what-you-sell). ### Unmatched quantity The quantity that matches no combination price. See [Fallback price: the price for everything else](/docs/20260301/pricing-models/concepts/dimensional#fallback-price-the-price-for-everything-else). ## V ### Volume pricing model The [pricing model](/docs/20260301/product-modules/products/glossary#pricing-model) that uses the total quantity to select one tier and charges every unit the price per unit of that tier. See [Volume pricing model: one price for every unit](/docs/20260301/pricing-models/concepts/volume#volume-pricing-model-one-price-for-every-unit). ## Related topics * [Concepts](/docs/20260301/product-modules/products/concepts/products) * [Walkthroughs](/docs/20260301/product-modules/products/walkthroughs/products) * [How-to guides: products](/docs/20260301/product-modules/products/how-to-guides/products) * [How-to guides: pricing presets](/docs/20260301/product-modules/products/how-to-guides/pricing-presets) * [How-to guides: metered usage](/docs/20260301/product-modules/products/how-to-guides/metered-usage) * [Reference](/docs/20260301/product-modules/products/reference/products) * [Pricing models](/docs/20260301/pricing-models/concepts/pricing-models) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
