Invoice Void & Allowance (作廢 / 折讓)

> STATUS: SKELETON — body pending.

When to use this skill

A return / refund occurs within same bimonthly → void
A return / refund crosses bimonthly boundary → 折讓
Debugging invoice state inconsistency post-refund
Building void / allowance SOP

Do NOT use when

Initial issuance → issuance-layer skill
Tax filing impact → tw-tax-basics

Core concepts

TODO: void vs 折讓, bimonthly boundary, accounting implications. NOTE (填充時): 此 skill 只寫「選哪條路」的決策邏輯，不重複 API 呼叫細節。 tw-ecom-invoice-ezpay 已有完整的 void_invoice / issue_allowance / trigger_allowance 步驟； tw-ecom-invoice-universalec 同理。此 skill 的 Implementation guidance 應只提供判斷框架，並用 "→ see tw-ecom-invoice-ezpay / -universalec" 指向 API 層。

Decision tree

TODO: given refund date vs issuance date → void or 折讓.

Implementation guidance

TODO: 決策路徑後的 SOP（accounting entries, customer notification, 字軌影響）。不重複 void_invoice / issue_allowance / trigger_allowance 的 API 參數 — 那些在 ezpay/universalec skill。

Gotchas

TODO: 5-6 pitfalls (boundary off-by-one, 字軌 reservation, lottery invalidation, allowance numbering).

IRON LAW

Measured example — same prompt, with vs. without the skill · from the benchmark run · case case-05

Prompt

An order was completed and invoiced on April 28th. On May 10th, the customer requested a partial refund for a damaged item. Should this be handled by voiding the original invoice or by issuing a tax allowance?

Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
