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) — strips PDF control bytes, escapes XML/CSV delimiters, and enforces QBXML field lengths before QuickBooks Enterprise import.

Direct Root Cause & Fix: QuickBooks Desktop Enterprise (QBXMLRP2 / Web Connector) throws HRESULT 0x80040400 (QuickBooks found an error when parsing the provided XML text stream) on SalesOrderAddRq whenever contractor PO fields contain unescaped & (B&G Pump), inch quotes (3/4"), UTF-8 fraction ligatures (¾), or PONumber > 25 characters.

Exact Field Constraints That Trigger 0x80040400

  • `PONumber` > 25 characters or `Customer` `FullName` > 41 characters per hierarchy level violates strict QBXML STRTYPE max-length schemas (0x80040400 parser rejection before QuickBooks even inspects business logic).
  • PDF Ligatures & Formula Prefixes: Copy-pasted PDF streams often embed 0x00–0x1F bytes, UTF-8 glyphs, or leading =, +, - characters.

Deterministic Fix

Sanitize descriptions, neutralize formula prefixes, and enforce QuickBooks PONumber and Item field bounds prior to batch import.
