Backcharge Notice Drafter

Turn a documented sub-tier failure — defective work, missed cleanup, damage to other trades, missed milestone, equipment misuse, no-show on a fix — into the disciplined paper chain that survives a sub's later mechanic's-lien claim, an attorney's review, and an owner's pass-through audit. Output a four-document package: (1) a written **Notice of Deficient Work** identifying the specific defect and demanding cure, (2) a **Notice of Intent to Cure & Backcharge** issued after the cure window expires, inviting the sub to observe the corrective work, (3) the itemized **Backcharge Notice** itself with cost detail and supporting attachments, and (4) the **Deduction Authorization Letter** instructing AP to net the backcharge against the next pay application. Each document is scoped to a single contract clause and a single timeline so the chain can be reconstructed in any later dispute.
