Devices, licenses, gigabytes, servers. You name the unit, set the rate, and the buyer picks how many they want at checkout. > [!NOTE] > > **Unit-based pricing is ideal for:** > > * Per-device or per-installation licensing > * Prepaid capacity, such as storage or bandwidth > * Any quantity that isn't a person and isn't measured after the fact > * Products where volume discounts should apply to the declared quantity ## Choosing between unit-based, seat-based, and metered Three pricing models charge by quantity. They differ in what the quantity counts and when the customer pays. | Model | The quantity counts | Customer pays | Benefits go to | | - | - | - | - | | **Unit-based** | Anything that isn't a person | Up front | The customer, once | | **Seat-based** | People | Up front | Each member who claims a seat | | **Metered** | Consumption you record | After the period | The customer, once | Pick seat-based when each unit maps to a person who needs their own access. Crosspoint then handles invitations, seat claims, and per-member benefits. Pick unit-based for everything else. Pick metered when Crosspoint counts the quantity for you, from usage events. With unit-based the buyer declares the number themselves, at checkout. ## How it works The buyer chooses a quantity at checkout and pays for it immediately. The price comes from the tiers you configure and the quantity they picked. On a subscription, the quantity carries across billing periods. You can change it at any time, and so can the customer if you let them. Crosspoint prorates the difference. On a one-time purchase, the quantity is fixed at the moment of sale. ## Creating a unit-based product **1. Create a new product** From your dashboard, [create a new product](https://staging.crosspoint.finance/to/dashboard/products/new). **2. Configure basic settings** Set your product name, description, and media as usual. **3. Select unit-based pricing** Under **Pricing**, select: * **Product type**: Subscription or One-time * **Billing cycle** (subscriptions only): Monthly or Yearly * **Pricing type**: Unit-based **4. Name the unit** Set the singular and plural nouns for what you're selling, such as `device` and `devices`. They appear at checkout, in the Customer Portal, and on invoices. Leave them empty and Crosspoint falls back to "unit" and "units". **5. Choose a tiering model** Under **Tiering model**, select how the quantity is priced: | Model | Description | | - | - | | **Fixed price per unit** | Every unit costs the same rate. | | **Volume** | The rate is set by the total quantity, and that rate applies to every unit. Crossing a threshold lowers the price on the whole order. | | **Graduated** | Each tier range is priced at its own rate. The total is the sum across ranges. | Define a tier by an upper bound and a rate. The bound is inclusive, and each tier starts where the previous one ended. Leave the last tier's bound empty for an open-ended top range. **Example** with tiers at up to 10: \$10 per unit, and beyond: \$8 per unit: * Volume: 14 units = 14 × \$8 = \$112. Every unit gets the lower rate. * Graduated: 14 units = 10 × \$10 + 4 × \$8 = \$132. Each range keeps its own rate. **6. Set a minimum and maximum** **Minimum units** is the smallest quantity a customer can buy. It defaults to 1. **Maximum units** caps the quantity a customer can buy. Leave it empty for unlimited, and customers can buy any quantity above the minimum. **7. Add benefits** Configure the benefits the customer receives on purchase. ### Combining with other prices Add a fixed price alongside the unit-based one for a base fee plus a per-unit rate. Metered prices can sit on top of both, so a subscription can charge a flat monthly amount, a rate per device, and usage on a meter. ## Benefits The customer receives each benefit once, whatever quantity they buy. Buying 40 devices grants one license key, not 40. If you need one grant per unit, use [seat-based pricing](https://staging-docs.crosspoint.finance/features/seat-based-pricing.md). ## Changing the quantity You can change the quantity on a subscription from your dashboard or through the API at any time. Customers can change it themselves from the Customer Portal once you allow it. Go to **Settings**, then **Customer portal**, and turn on **Enable subscription unit changes**. It is off by default. ### Proration When the quantity changes mid-period, Crosspoint prorates the difference using your organization's proration behavior: * **Increasing the quantity** charges for the added units, prorated over the remainder of the period. * **Reducing the quantity** credits the removed units for the unused part of the period. The full amount applies from the next billing period onward. ## Limitations * The quantity is a whole number. Fractional quantities need [metered billing](https://staging-docs.crosspoint.finance/features/usage-based-billing/introduction.md) instead. * Tier rates are whole cents. * A product carries at most one unit-based price. * Unit-based cannot be combined with seat-based or pay-what-you-want pricing. * One-time purchases cannot change quantity after the sale. The customer buys again instead. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
