Spreadsheet Failure ModeManual Workflow
Root Operational Bottleneck
Letter-of-credit terms are read from paper and retyped into the wire sheet, so a discrepancy between the LC and the shipping documents is found only when the bank refuses the draw.
Control Hazard & Audit Exposure
Cargo sits in customs while the discrepancy is repaired, because the wire was prepared from a typed extract rather than the LC itself.
Deterministic Software ReplacementClient-Owned Architecture
Trade Document Ingestion & Deterministic LC Compliance Gateway
Trade-document ingestion that compares the LC, invoice, and transport docs field by field and blocks the draw until every required term matches.
Continuous Assertion Rule
Compliance assertion: a draw cannot release unless every required LC field matches the presented documents, with mismatches listed on the block.
