# settleDebitNoteToAr

mutation · in the family [Refunds and payment corrections](/reference/refunds-and-payment-corrections/)

## What it does

Settle a debit note into the customer’s house account — the charge lands on their AR balance.

SETTLE an ISSUED DebitNote against the customer's AR: posts the charge AREntry (= totalDeltaMinor; dueAt per the enablement's NET terms — cod/prepaid/undeclared refuse CONFLICT/REF_STATE, a DN needs a due date to ride AR) + the SAME-transaction settled+closed flip. ⚠ NOT limit-gated (the disclosed lean — a correction documents debt that already exists; only the TENDER extends new credit). Requires the unrestricted capability + the record's CURRENT revision.

## Who may call it

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `input` | [SettleDebitNoteToArInput](/types/SettleDebitNoteToArInput/) `SettleDebitNoteToArInput!` | yes | No further notes. |

## Returns

[DebitNote](/types/DebitNote/) `DebitNote!` — A DebitNote — the INCREASING corrective twin of the CreditNote (customer owes MORE — an undercharge correction, post-billing freight, an upward price adjustment): identical lifecycle + delta mechanics, OPPOSITE sign (every figure strictly POSITIVE). The tax delta recomputes over the invoice line's CAPTURED components; NO over-credit ceiling (an increase raises the invoice's remaining net — the CreditNote guard reads the raised headroom via the same cumulative stamps). NO inventory movement. Reuses the CreditNote's NoteDeltaLine/NoteDeltaTaxComponent SDL types (the /VendorInvoice entry-order precedent).
