# Sintropix Expense Claims API: Submit and Approve Renditions

> Submit an expense a person paid with their own money, and let the Organization's Approver approve it into a booked Expense Rendition or reject it. Name the Expense Categories of each Entity, and set the Approver and the Source and accounts each Entity books with.

An **Expense Claim** (rendición) is one expense that a person paid with their own money and asks the Entity to pay back. You submit it in Sintropix itself, with no outside tool such as Rindegastos. It waits until the Organization's **Approver** approves or rejects it:

* **Approved:** Sintropix creates the person's payable Invoice in a Source that holds [Expense Renditions](https://docs.sintropix.com/api-reference/sources.md#sources-that-hold-expense-renditions), and books it in the same request. From then on it's an Expense Rendition like any other, and you pay it from a [Payment Batch](https://docs.sintropix.com/api-reference/payment-batches.md).
* **Rejected:** the claim keeps the reason, and the decision is final. To try again, submit a new claim.

An [Xpendit expense Feed](https://docs.sintropix.com/api-reference/source-feeds.md#sync-an-expense-feed) also creates claims: each expense Xpendit approved lands as a claim that is already `approved`, with no wait for the Approver.

While a claim waits, it is no Invoice. It isn't listed among the Expense Renditions or in **Compras**, isn't a payable to plan in a Payment Batch, and doesn't count on the home dashboard.

> [!TIP]
>
> **Open in the app.** This resource has a page in the Sintropix web app at `https://app.sintropix.com/{entityId}/expense-renditions?expenseClaimStatus=submitted`, where each id in braces is the same UUID as in the API route or response. Rendiciones, under Datos. Por aprobar (expenseClaimStatus=submitted) lists the claims that wait, with the Approve and Reject actions, and Rechazadas (expenseClaimStatus=rejected) lists the rejected ones. Both show each claim's Número. Drop the parameter for the Expense Renditions. Nueva rendición submits a claim. When you mention a record to a user, include that link. See [Link to the App](https://docs.sintropix.com/guides/app-links.md) for the full URL grammar.

## Concepts

* **Person.** The Partner who paid the expense and is paid back, never the merchant.
* **Receipt Kind.** What the person holds as proof: a `boleta` or a `factura` issued to the Entity. It decides what the approval debits. See [What approving books](#what-approving-books).
* **Expense Category.** What the expense was spent on, such as "Alimentación" or "Movilización". Each Entity names its own categories, and each category can carry the expense account its claims propose. See [Expense Categories](#expense-categories).
* **Proposed expense account.** The expense account the claim suggests: the account of the claim's category, or one the submitter names. It must be an account of type `cost_of_goods_sold`, `operating_expense`, or `other_expense`. The Approver can pick another one on approval.
* **Number.** Each claim takes the next number of its Entity when you submit it: 1, 2, 3, and so on. Numbers never repeat within an Entity. The Expense Rendition of an approved claim carries it as its Document Number, `R-<number>`, so a claim reads the same before and after approval.
* **Approver.** The one User of the Organization who approves and rejects the claims of all its Entities. It must be a member with the `client` Role: someone of the client's own team, never Sintropix staff or a `viewer`. The Approver role ends when the User's Membership ends.
* **Status.** Sintropix derives it, and never stores it:
  * `submitted`: the claim waits for the Approver.
  * `approved`: the claim has its Expense Rendition, in `invoiceId`.
  * `rejected`: the claim has a `rejectionReason`.

Who approved or rejected a claim, and when, is in the [Audit Trail](https://docs.sintropix.com/api-reference/audit-trail.md). Once a claim is approved, the **Actividad** of its Expense Rendition shows who submitted it and who approved it.

## Before you submit claims

Approving needs two settings. Set them in **Configuración → Rendiciones**, at `/{entityId}/settings/expense-claims`, or through the API:

1. **The Approver of the Organization.** Use [`PUT /organizations/:organizationId/expense-claim-approver`](#put-/organizations/organizationid/expense-claim-approver).
2. **The booking setting of each Entity.** Use [`PUT /expense-claim-setting`](#put-/expense-claim-setting). It names three things:
   * The Source the Expense Renditions land in. It must be a Source that [holds Expense Renditions](https://docs.sintropix.com/api-reference/sources.md#sources-that-hold-expense-renditions).
   * The **Rendición por pagar** account, which the approval credits with the person as Partner. It must be a `liability` account with the sub-type [`expense_rendition_payable`](https://docs.sintropix.com/api-reference/chart-of-accounts#expense-rendition-payable). If the Entity already books renditions into a `payable` account, you can [switch its sub-type](https://docs.sintropix.com/api-reference/chart-of-accounts.md#sub-type-changes-on-an-account-with-entries) to `expense_rendition_payable` even though it has entries.
   * The supplier payable account, which a `factura` claim debits. It must have the sub-type `payable`, and it must be the account the Entity's SII invoices credit, so that you can [match](https://docs.sintropix.com/api-reference/allocations.md) the two lines later.

You can submit claims before you set either one. Only approving and rejecting need them.

To let submitters pick a category instead of an account, also create the Entity's [Expense Categories](#expense-categories) and assign each one its expense account.

In the app, each pick saves at once, with no **Guardar** button. The booking setting saves once the Source and both accounts are set.

While the setting names a Source, you can't unmark the Source as one that holds Expense Renditions, or delete it. Sintropix refuses both with `409` and `SOURCE_PINNED_ERROR`. Each account also keeps its sub-type while the setting names it: a change is refused with `409` and `LEDGER_ACCOUNT_FACT_PINNED_ERROR`. To change any of them, set another one first.

## Report a rendition to Erwin

A person can also report a rendition to Erwin, for example in a Slack channel bound through an [Agent Channel](https://docs.sintropix.com/api-reference/agent-channels.md): *"pagué un almuerzo con cliente con mi tarjeta, ¿me lo devuelven?"*. Erwin submits it as an Expense Claim, and the Approver approves or rejects it like any other claim. Erwin never approves, rejects, or books the claim himself.

1. **Erwin checks the setup.** When the Entity has no [booking setting](#before-you-submit-claims) or the Organization has no Approver, Erwin submits nothing. He tells you that Rendiciones isn't set up yet, and that someone who keeps the books sets it in **Configuración → Rendiciones**.
2. **He gets the facts.** Erwin asks for a proof if you sent none: a photo, a receipt, or a screenshot. He reads the date, the merchant, and the amount from it, and asks only for what it doesn't show. The amount is what the Entity pays back, in its functional currency. When the proof is in another currency, he asks what was charged to you in the functional currency, as your card statement shows it. The claim is a `factura` when the proof is a factura electrónica issued to the Entity's RUT, and a `boleta` otherwise, including when there's no document.
3. **He submits the claim.** The person who paid is the claim's Partner, never the merchant. Erwin creates the Partner when there's none. The `memo` holds the merchant, what the expense was, and the other facts the Approver needs, such as the payment method, the document number, and the original currency and amount. A claim holds no file, so when you report it from Slack, the memo ends with a link to the Slack message that holds the proof.
4. **He proposes what it was spent on.** Erwin names an [Expense Category](#expense-categories) when one clearly fits the expense and has an expense account. Otherwise he proposes an expense account, following your Organization's practices in his wiki. He never creates a category, and the Approver can book to another account.

Erwin answers that the rendition is submitted and waits for the Approver, with its amount, its memo, and a link to **Rendiciones → Por aprobar**. He doesn't say which account he proposed: that's for the Approver.

## What approving books

Approving creates one `payable` Invoice and books it in the same request:

| Invoice field | Value |
| - | - |
| `partnerId` | The claim's person |
| `sourceId` | The Source of the Entity's setting |
| `documentKind` | `invoice` |
| `documentNumber` | `R-<number>`, from the claim's `number`, for example `R-12` |
| `currency`, `total` | The Entity's functional currency, and the claim's `amount` |
| `issueDate` | The claim's `expenseDate` |
| `memo` | The claim's `memo` |

The booking entry is dated on the expense date. Its Control Line credits the **Rendición por pagar** account with the person as Partner. The debit depends on the Receipt Kind:

| Receipt Kind | Debit | Why |
| - | - | - |
| `boleta` | The expense account: the proposed one, or the one the Approver picks | The expense exists only in the claim. |
| `factura` | The supplier payable account of the setting | The factura was issued to the Entity, so its expense and IVA reach the books with the SII invoice. Debiting an expense account would book it twice. |

For a `factura`, the claim keeps the expense account as the suggestion for booking the SII invoice. The debit to the supplier payable stays open until you settle it against the Control Line of the SII invoice with [`POST /ledger/allocations/match`](https://docs.sintropix.com/api-reference/allocations#post-/api/entities/entityid/ledger/allocations/match). The SII invoice then reads as paid.

If you unbook the Expense Rendition and [delete](https://docs.sintropix.com/api-reference/invoices.md#delete-/invoices/invoiceid) it, the claim loses its `invoiceId` and is `submitted` again.

## Access

| Route | Who can call it |
| - | - |
| Read claims, the setting, or the Approver | Any member of the Organization |
| Read Expense Categories | Any member of the Organization |
| Submit a claim, create, change, or delete an Expense Category, set the Approver, or set the setting | A member with the `staff` or `client` Role. The Approver they set must be a `client` member. |
| Approve or reject a claim | The Approver alone, from a session or their own API key |

A `viewer` who writes receives `403` with `PERMISSION_DENIED_ERROR`. Anyone but the Approver who approves or rejects receives `403` with `EXPENSE_CLAIM_NOT_APPROVER_ERROR`, even a `staff` member. See [Access and roles](https://docs.sintropix.com/api-reference/overview.md#access-and-roles).

## The Expense Claim object

## POST `/expense-claims`

Submit an Expense Claim. It starts as `submitted`, with the next `number` of its Entity.

**Body**

| Field | Type | Required | Description |
| - | - | - | - |
| `id` | uuid | Yes | Id of the new claim. You choose it, so a retried request can't submit the claim twice. A second request with the same `id` receives `409` with `EXPENSE_CLAIM_ALREADY_EXISTS_ERROR`. |
| `partnerId` | uuid | Yes | The person who paid. A Partner of the Organization. It can't be the Partner that represents the Entity, or a Merged Partner. |
| `expenseDate` | date (`YYYY-MM-DD`) | Yes | When the expense was paid. |

| `memo` | string | Yes | Non-blank after trimming. |
| `receiptKind` | `boleta` \| `factura` | Yes | The proof the person holds. |
| `expenseCategoryId` | uuid | One of the two | An [Expense Category](#expense-categories) of the Entity. The claim proposes the category's expense account. A category with no account yet receives `409` with `EXPENSE_CATEGORY_EXPENSE_ACCOUNT_NOT_SET_ERROR`. |
| `expenseAccountId` | uuid | One of the two | The proposed expense account: an account of the Entity of type `cost_of_goods_sold`, `operating_expense`, or `other_expense`. |

Send exactly one of `expenseCategoryId` and `expenseAccountId`. A body with both, or with neither, receives `400`.

In the app, **Nueva rendición** asks for a **Categoría**, and the picker shows each category's account or **Sin cuenta asignada**. A category without an account is refused, and the dialog keeps your draft so you can assign the account in **Configuración → Rendiciones** and submit again.

**Response** (`201`): the Expense Claim object.

```

## Expense Categories

An **Expense Category** names what an expense was spent on, such as "Alimentación", "Movilización", or "Hospedaje". Each Entity keeps its own list. A category can carry an expense account: a claim that names the category proposes that account, so the submitter picks what the expense was, not where it books.

* A category's name is unique within its Entity. Sintropix trims surrounding spaces, so `" Taxi "` and `"Taxi"` are one name.
* A category starts with no account. Assign one before a claim names it.
* You can rename a category and assign it another account, but you can't clear an account once it's assigned.
* The account must be an expense account of the Entity: of type `cost_of_goods_sold`, `operating_expense`, or `other_expense`.
* You can delete a category while no Expense Claim names it. Once a claim names it, whatever the claim's status, the category stays: rename it instead.

In the app, open **Configuración → Rendiciones**. The **Categorías** card lists the Entity's categories. Add one with **Agregar categoría**, rename it in place, and pick its **Cuenta de gasto**. To remove a category, click the trash icon on its row and confirm. A name can't be blank: clearing it is refused with *El nombre es obligatorio. Para quitar la categoría, elimínala.*

> [!TIP]

> **Open in the app.** This resource has a page in the Sintropix web app at `https://app.sintropix.com/{entityId}/settings/expense-claims`, where each id in braces is the same UUID as in the API route or response.  When you mention a record to a user, include that link. See [Link to the App](https://docs.sintropix.com/guides/app-links.md) for the full URL grammar.

### DELETE `/expense-categories/:expenseCategoryId`

`DELETE /api/entities/:entityId/expense-categories/:expenseCategoryId`

Delete a category that no Expense Claim names, such as one created by mistake. The call has no body.

* An unknown id receives `404` with `EXPENSE_CATEGORY_NOT_FOUND_ERROR`.

> [!NOTE]
>
> A category that an [expense Feed](https://docs.sintropix.com/api-reference/source-feeds.md#expense-categories-from-xpendit) brought comes back the next time the Feed reads an expense of that category. It returns with no expense account, so the expense is rejected with `expense_category_unassigned` until you assign one again. In the app, the delete confirmation of such a category says so.

**Response** (`200`): the deleted Expense Category object.

```bash theme={"system"}
