AUTOMATED PRE-ERP QUARANTINE & TRANSPARENT PRICING

OrderAirlock blocks P21-SISM-IMPLNE-PRICE-VARIANCE-HOLD deterministically with zero LLM calls before bad quantities or prices enter Epicor Prophet 21 (P21) SISM. Starter: $249/mo ($2,490/yr annual, 500 POs/mo) · Distributor & FDE Pro: $499/mo ($4,990/yr annual, 2,500 POs/mo) — 0% transaction cut.

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) — blocks stale buyer quotes and 2-decimal pack-split rounding drift in integer micro-dollars before SISM import.

Direct Root Cause & Fix: Importing unverified buyer unit_price values into Epicor P21 IMPLNE either silently overrides your current P21 customer price matrix with last year's stale quote (eroding 4%–12% gross margin) or parks the order on P21 Margin/Price Hold when unit_quantity * unit_price != extended_price.

Two Classic P21 Price-Import Failure Modes

  1. Silent Stale-Quote Bleed: SISM honors explicit unit_price columns when mapped as manual price overrides, letting outdated customer PDF templates under-bill copper, PVC, or refrigerant after manufacturer price increases.
  2. Float Truncation Rejections: Converting $14.00 / 12 = $1.16666... to $1.17 produces 12 * $1.17 = $14.04 != $14.00.

Deterministic Fix

  • Store unit rates in 1e-6 USD micros (1,166,667 micros -> 1.1667 formatted to 4 decimals in unit_price) and compare price_variance_pct against your workspace threshold (default 1.0%), flagging quarantine_price_variance with exact dollar margin at risk before export.
