  - name: Customers
    description: >-
      A `Customer` is an entity connected to a `Merchant` via a `Subscription`.
      This represents the merchant-facing perspective of `Consumers` who
      purchase their `Products`.
  - name: Billable Metrics
    description: >-
      A `Billable Metric` defines a measurable quantity tied to a `Product`'s
      consumption. Each metric stores details including its label, an
      explanatory description, and measurement units.
  - name: Grants
    description: >-
      Grants credit a customer's metered entitlement balance. Merchants can
      create grants directly or void existing ones.


      Use `GET /v1/entitlements?customerId={id}` or `GET
      /v1/entitlements?subscriptionId={id}` to find the metered entitlement `id`
      needed for these endpoints.
  - name: Features
    description: >-
      A `Feature` represents a specific capability or functionality provided by
      a `Product`. Features can be metered (usage-based), static (fixed
      allocation), or boolean (enabled/disabled).
  - name: Fees
    description: >-
      A `Fee` defines a recurring or one-time charge tied to a `Product`. Fees
      are linked to prices, and cadence is defined on the Price.
  - name: Plans
    description: >-
      A `Plan` links a collection of `Prices` to a `Product`. It functions as a
      pricing structure document for a particular feature set or service
      offering.
  - name: Prices
    description: >-
      A `Price` determines the monetary value for a single unit of a `Billable
      Metric`. Prices are exclusively grouped within a `Plan`.
  - name: Products
    description: >-
      A `Product` is an offering sold by a `Merchant`. It includes product
      metadata like title, summary, and pricing details. `Plans`, `Prices`, and
      `Subscriptions` are all associated with products.
  - name: Sources
    description: >-
      A `Source` is an external data provider capable of automatically creating
      usage events. Configuration occurs at the plan level, enabling data
      retrieval from third-party platforms such as Stripe to produce billable
      events.
  - name: Subscriptions
    description: >-
      A `Subscription` is a customer's commitment to purchase a `Product`
      following the terms of a `Plan` and its linked `Prices`.
  - name: Users
    description: >-
      A `User` is an entity granted access to an Organization's resources. All
      operations are performed by users.
  - name: Invoices V2
    description: >-
      Invoice V2 operations supporting billing cycles organized by time periods.
      Warning: v0 invoice endpoints are no longer supported.
  - name: Revenue
    description: Revenue data from invoices and payments
  - name: Profitability
    description: Per-customer profitability summaries
  - name: Test Clocks
    description: >-
      Test clocks provide programmable time control to simulate subscription and
      billing scenarios during testing.
  - name: Events
    description: Ingest raw metering events that are processed by the meters service.
  - name: Payments
    description: >-
      Create and manage one-off payments. A payment represents a single charge
      that a merchant wants to collect from a customer.
  - name: Payment Sessions
    description: >-
      Handle payment session lifecycle and processing across various entity
      types including invoices and subscriptions
  - name: Costs
    description: >-
      A Cost represents the operational or infrastructure expense of serving
      customers for a given product. Costs are metered (driven by event-based
      usage) and are tracked in parallel with billable metrics to give merchants
      visibility into both revenue and cost per customer.
  - name: ExternalReferences
    description: >-
      An `ExternalReference` links a Paygentic entity (e.g. an `Item`) to a
      record in an external system such as Salesforce or NetSuite. Multiple
      external records may map to the same Paygentic entity, but each external
      id is the *primary* reference of at most one entity per merchant.
  - name: Items
    description: >-
      An `Item` is the canonical "thing you sell" that external-system mappings
      point at. It is fully decoupled from the billing `Product` and holds no
      pricing/plan/metering, and it is CRM/ERP agnostic — which providers map to
      it lives entirely in its `ExternalReference` rows.
  - name: MerchantIntegrations
    description: >-
      A `MerchantIntegration` records a merchant's connection to an external
      provider. One connection per `(merchant, provider)` — re-connecting
      upserts in place.
  - name: Approvals
    description: Submit, decide, cancel, and read maker-checker approvals.
  - name: Orders
    description: Manage Orders, their line items, and billing schedules.
  - name: Billing Schedules
    description: >-
      Owner-polymorphic billing schedules with intervals and staged invoice
      projections. A BillingSchedule belongs to exactly one Order or one
      Subscription (XOR). Cadence lives on ScheduleIntervals
      (cadence-on-the-line).
