Product/Topic: EDIFACT - INVOIC (D.01B)
The EDIFACT INVOIC (D.01B) is a United Nations (UN) standard Electronic Data Interchange (EDI) message used to claim payment for goods or services supplied between a seller and a buyer. It communicates financial, commercial, tax, payment, and line-item details required by trading partners for billing and financial settlement processes.
Understanding the structure of the INVOIC message is important when configuring, mapping, or troubleshooting invoice transactions within your Electronic Data Interchange (EDI) setup. The INVOIC (D.01B) supports standard invoices, credit notes, and debit notes, and facilitates billing, accounts payable, accounts receivable, taxation, and financial reconciliation processes between trading partners.
