Delivery Confirmation

Delivery confirmation in accounts receivable and billing operations refers to the verified proof that an invoice, statement, or payment demand has been successfully received by the intended recipient — whether transmitted electronically (email delivery receipt, portal download acknowledgment) or physically (USPS tracking, certified mail return receipt). Delivery confirmation is critical in the order-to-cash cycle because it establishes the legal start of payment terms, validates that dunning communications were received (essential for collections escalation and legal proceedings), and eliminates the most common customer dispute: "I never received the invoice." Research from Ardent Partners shows that 15–22% of payment delays are attributed to claimed non-receipt of invoices, and implementing delivery confirmation reduces this dispute category by 80–90%. In electronic invoicing, delivery confirmation includes email open/read receipts, EDI functional acknowledgments (997/999 transactions), and customer portal login verification timestamps. For physical mail, USPS Certified Mail with return receipt ($4.10 per piece) provides legal proof of delivery, while Intelligent Mail Barcodes enable tracking of standard first-class mail at no additional cost. Quadient AR and electronic invoice presentment platforms provide automated delivery confirmation through multi-channel distribution — email with read tracking, customer portal delivery with download confirmation, and EDI acknowledgment processing — ensuring that every invoice has a verifiable delivery record. This delivery confirmation data feeds into automated dunning workflows: if an invoice shows no delivery confirmation within 48 hours, the system automatically retransmits through an alternative channel, reducing lost invoices to near zero and accelerating the start of the payment clock.
