For task steps, see [how to add a product](/docs/20240301/product-modules/products/how-to-guides/add-a-product) and [how to manage products](/docs/20240301/product-modules/products/how-to-guides/manage-products). For the reasoning behind these fields, see [products: concepts](/docs/20240301/product-modules/products/concepts/products) and [features: concepts](/docs/20240301/product-modules/products/concepts/feature). ## Product fields | Field | Required | Description | | ----------------- | -------- | ---------------------------------------------------------------------------------------------------------------------------- | | Product Name | Yes | Name of the product, shown on invoices and reports. Labeled Product Bundle Name if the product is a bundle. | | Description | No | Internal description of the product. | | SKU | No | Stock keeping unit, useful for syncing with an ERP or inventory system. | | Tax Code | No | Determines how the product is taxed. Not shown for bundles, since tax resolves at the level of each product inside a bundle. | | Custom attributes | Depends | Shown only if your organization has defined custom attributes for the Products module. | | Type | Yes | Standalone product, or bundle (a group of other products). | | Status | Yes | Active or inactive. Defaults to active. | ## Type | Type | Description | | ---------- | ------------------------------------------------------------------------------ | | Standalone | A product priced and sold on its own. | | Bundle | A product that groups several other products together under one catalog entry. | ## Pricing models A product's pricing is configured separately from the product itself, through one or more pricing models attached to it. | Pricing model | What it does | | ------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | | [Per-unit](/docs/20240301/pricing-models/per-unit) | A fixed rate multiplied by quantity. | | [Flat fee](/docs/20240301/pricing-models/flat-fee) | A fixed price agreed upfront, independent of quantity. | | [Percent](/docs/20240301/pricing-models/percent) | A percentage of a transaction value or of usage, rather than a fixed per-unit rate. | | [Tiered](/docs/20240301/pricing-models/tiered) | Usage is split across tiers, and each tier is billed at its own rate. | | [Tiered pricing with flat fee](/docs/20240301/pricing-models/tiered-pricing-with-flat-fee) | A flat base fee plus usage billed per tier, each tier at its own rate. | | [Volume](/docs/20240301/pricing-models/volume) | The total quantity determines a single rate applied to every unit. | | [Volume pricing with flat fee](/docs/20240301/pricing-models/volume-with-flat-fee) | A flat fee plus usage billed across volume tiers, with each tier carrying its own flat fee. | | [Step](/docs/20240301/pricing-models/step) | Usage is divided into tiers, and each tier is billed at its own flat fee rather than a per-unit rate. | | [Package](/docs/20240301/pricing-models/package) | Sold as a fixed-size bundle at a fixed price. | | [Matrix](/docs/20240301/pricing-models/matrix) | The rate depends on two dimensions, for example usage and region. | | [Two-dimensional tiered](/docs/20240301/pricing-models/two-dimensional-tiered) | Tiers are set across two independent factors at once, rather than one. | | [Custom tiered](/docs/20240301/pricing-models/custom-tiered) | Mixes tiered, package, and per-unit rates within the same tier structure. | ## Feature types These are the feature types available at the product level. Payment terms and service fees aren't among them, those are contract-level features instead. See [contracts reference: feature types](/docs/20240301/product-modules/contracts/reference/contract#feature-types) for that set. | Feature | What it does | | ------------ | ------------------------------------------------------------------------ | | Discount | Reduces the charge. Fixed, percent, or quantity-based. | | Tax | Applies a tax rate, either entered manually or resolved through Avalara. | | Free units | Grants a number of units the customer isn't charged for. | | Commitment | Sets a minimum spend the customer is held to. | | Grants | Issues an entitlement, a pool of usage triggered by an event you choose. | | Consumptions | Defines how usage draws down a grant. | ## How product changes affect contracts | Change | Effect on contracts already using the product | | -------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- | | Editing name, description, SKU, tax code, or custom attributes | Not blocked. Existing contracts are flagged as needing a refresh rather than updated automatically. | | Setting status to inactive | Not blocked. Existing contracts keep working. | | Deleting the product | Blocked while any contract, plan, or bundle still references it. | | Deleting a pricing model | Blocked while any contract still references that specific pricing model. |
