# Invoices

Invoices are issued against a booking once its services have been confirmed. They sit alongside receipts, credit notes, refund notes, and reversal notes under the shared `documents` GraphQL connection.

## Issuance lifecycle

An invoice moves through three states that are visible on the `issuedDetails` field of every accounting document:

| State   | `issuedDetails` | `issuingStartedAt` | `issuedAt` |
| ------- | --------------- | ------------------ | ---------- |
| Draft   | `null`          | n/a                | n/a        |
| Issuing | non-null        | set                | `null`     |
| Issued  | non-null        | set                | set        |

`issuedDetails` is `null` until the issue command is dispatched. Once issuance has started, `issuedDetails.issuingStartedAt` is set and remains set until issuance completes or is rejected by the tax authority. Use `issuedDetails.issuedAt` to detect the terminal "issued" state, which is what consumers should rely on to mark an invoice as fully issued.

> **Note:** Before May 2026 the `issuedDetails` outer null check meant "fully issued". From May 2026 onwards it means "issuance has started", so existing consumers must switch to checking `issuedDetails.issuedAt != null` for the same semantics.

## Querying an invoice

```graphql
query Invoice($id: ID!) {
  accounting {
    documents(filters: { workspaceId: { eq: "workspace-id" }, id: { in: [$id] } }) {
      edges {
        node {
          id
          issuedDetails {
            displayDocumentNumber
            issuingStartedAt
            issuedAt
            balance { amount currency }
          }
        }
      }
    }
  }
}
```

```json
{ "id": "invoice-id" }
```

Payments allocated against this invoice are documented on the [Payments](/finance-and-accounting/payments.md) page.
