# Get Bill Deferral

`GET /companies/{company_id}/gl/items/{item_id}/deferral`

## Request

- Base URL: `https://app.zeno-works.ch` (the document declares no server; this is the origin it was published from)
- URL: `https://app.zeno-works.ch/companies/{company_id}/gl/items/{item_id}/deferral`
- Auth: none declared

Prefill for deferring a booked supplier bill ("Defer…" on its document page) —
accountant (ZCT-876).

Returns the bill's expense accounts with the base-currency amount booked to each (the
most that can be deferred from it — never the VAT or the payables leg), the configured
active accrual (ARA) account the deferred amount moves to, the bill's posting date (the
reclass date) and the document's service period, its start clamped up to the bill's
date. Refuses with the same coded 409/422 the ``POST`` would — not booked, not a
supplier invoice (a credit note or a customer invoice), already deferred, an AI-guessed
account, a registered fixed asset, a closed period.
