Interchange Control
Interchange control numbers and envelope headers (ISA/GS) identify sender/receiver, control counts, and character encoding so partners can validate transmission integrity and detect truncation.
Standardized EDI documents reduce manual rekeying, improve data accuracy, and accelerate order-to-cash cycles while supporting automated validation and exception handling across systems.
EDI documents are used by organizations that exchange high volumes of structured transactions—procurement, logistics, and finance teams are the primary users.
Trading partners, EDI service providers, and system integrators also manage mapping, validation, and exception workflows to keep exchanges reliable and auditable.
Interchange control numbers and envelope headers (ISA/GS) identify sender/receiver, control counts, and character encoding so partners can validate transmission integrity and detect truncation.
A clear header containing transaction type, document date, buyer and seller identifiers, and purchase order or invoice number allows automated matching and routing in ERP systems.
Structured name and address segments for buyer, seller, ship-to, and bill-to with standardized identifiers (e.g., GLN, DUNS, or partner-assigned IDs) reduce ambiguity during settlement.
Per-line SKU, quantity, unit of measure, unit price, and extended line totals enable automated receipt matching, inventory updates, and invoice validation.
Document-level totals, tax amounts, and currency codes provide the financial summary required for accounts payable processing and tax reporting reconciliation.
Check sums, segment counts, and trailer control numbers ensure the file is complete and unaltered between sender and receiver during transmission.

EDI exchanges use standard transport and file formats and typically integrate with ERP, WMS, and accounting systems for end-to-end processing.
Ensure your platform supports PDF, DOCX, and native EDI formats and integrates with systems like NetSuite, Salesforce, Microsoft 365, and Google Workspace for automated workflows.
