Write-Offs

Overview

There are occasions where an individual or set of invoices may be deemed uncollectible, but still need to become settled so that they dont remain on the system, forever in an incomplete state. Additionally, use cases such as fee discounts at the invoice item level require an even more precise degree of credit handling. Write-Offs allow users to write off entire invoices, specific invoice items or partial amounts.

Key Capabilities

  • Target either full invoices or individual invoice items.

  • Specify a custom amount per target, or allow the system to compute the unsettled amount.

  • Supports partial write-offs of invoice items.

  • Multiple targets per write-off are supported, processed in the order provided.

  • Write-offs propagate to DataLake for downstream reporting.

  • A full reversal capability is supported via a simple POST call.

Accounting Behavior

Granular write-offs follow the same accounting rules as traditional full invoice write-offs. Each target is processed independently and credited accordingly.

API Usage

Create a write-off by specifying one or more invoice or invoiceItem targets. All targets must belong to the same account and use the same currency.

Create Write-Off
writeOff
POST /billing/{tenantLocator}/writeOffs
    Request Parameters:
    NamePositionTypeRequired
    tenantLocatorpathuuidrequired
    Request:WriteOffRequest
    Response:WriteOffResponse
    Security Group:write-offs   Permission:write
WriteOffRequest
required
accountLocator string
targets WriteOffTarget[]
WriteOffTarget
required
containerLocator string
containerType Enum account | invoice | invoiceItem | subpayment

optional
amount number?

Note

Invoices can also be directly targetted for write off via their locator, however this approach is limited in that it can target only the remaining balance of the invoice, and in its entirety.

Write-Off an Invoice
writeOffInvoice
PATCH /billing/{tenantLocator}/invoices/{locator}/writeOff
    Request Parameters:
    NamePositionTypeRequired
    tenantLocatorpathuuidrequired
    locatorpathstringrequired
    Response:WriteOffResponse
    Security Group:invoices   Permission:write

Reversal Support

Write-offs can be fully reversed using the existing reversal endpoint, unsetting all credits made across all invoice and invoiceItem targets. Partial reversals are not supported.

Reverse a Write-Off
reverseWriteOff
PATCH /billing/{tenantLocator}/writeOffs/{locator}/reverse
    Request Parameters:
    NamePositionTypeRequired
    tenantLocatorpathuuidrequired
    locatorpathstringrequired
    Response:WriteOffResponse
    Security Group:write-offs   Permission:write

Limitations

  • Maximum targets: A request can include up to 100 a fixed maximum number of targets. Requests exceeding this limit will be rejected.

  • Same account constraint: All targets (invoice and invoiceItems) must belong to the account specified in the request. Cross-account targeting is not allowed.

  • Same currency: All targets in a request must have the same currency.

  • No duplicate targets: Each target must be unique. Duplicate invoice or invoiceItem entries within the same request will result in an error.

  • Disjoint targets: invoiceItems cannot be targeted individually if they are already indirectly included via their parent invoice in the same request. Each target must be independent.

  • Valid types only:

    • Only invoice and invoiceItem container types are supported.

    • Other types (e.g., account) are not valid targets.

  • Target must exist: All provided target locators must correspond to existing invoices or invoice items; otherwise, the request will fail.

  • Amount must be valid: The amount specified per target must be positive and non-zero. The amount must not exceed the target’s remaining unsettled amount.

  • Settled items cannot be written off: Targets that are already fully settled are not eligible for write-off.

  • Targets are required: A write-off request must include at least one valid target.
