Automated Fix & Pricing (`OrderAirlock`): Starter $249/mo ($2,490/yr annual, 500 POs/mo) · Distributor/FDE Pro $499/mo ($4,990/yr annual, 2,500 POs/mo) — enforces SHA-256 inbound attachment deduplication and deterministic SO-<po_number> + ItemLine_LineNumber grouping.

Direct Root Cause & Fix: Single-file multi-line SalesOrder CSV imports in NetSuite fail via (a) This record already exists when an emailed PO is uploaded twice under ADD mode, or (b) silent line-item overwrites under ADD OR UPDATE mode when ItemLine_LineNumber keys collide or ExternalId differs across rows.

How Silent Line Overwrites Happen

When contractors resend a revised PDF PO (Rev B) or an ops clerk runs NetSuite CSV Import with Overwrite Sublists = True and missing Line ID / ItemLine_LineNumber mapping, NetSuite replaces existing lines or drops duplicate-SKU rows with different job-site notes.

Deterministic Safeguards

  1. Hash inbound email/upload payloads (SHA-256) and flag duplicate (customer_code, po_number) pairs before ERP export.
  2. Emit deterministic ExternalId = SO-<po_number>, OtherRefNum = <po_number>, and strict 1..N ItemLine_LineNumber values for safe ADD mode imports.
