3PL Bill Check — An evidence-linked invoice reviewer

Field notes

The documented workflow requires one billing period’s rate-card, invoice-line, and Shopify-activity exports, with explicit column mapping rather than inference from descriptions. Its checks distinguish ordinary rate differences from uncontracted services, duplicate references, effective-date problems, quantity mismatches, and minimum-charge cases. The output retains rule IDs, confidence, and source-row references, while the operator selects findings for CSV, print, or email export. The page states that parsing happens in browser memory and that no direct Shopify or WMS connection is used.
