US DBNAlliance hosts first national e-invoicing conference — voluntary Peppol-style network grows
The Digital Business Networks Alliance (DBNAlliance) hosted the United States E-invoicing Conference in New York on 22 April 2026, convening Microsoft, Halliburton and government bodies. The US has no federal e-invoicing mandate; adoption is market-driven through the DBNAlliance 4-corner exchange framework — a Peppol-derived network using UBL 2.x/PINT derivatives with AS4/AS2 protocols. The US-EU Trade and Technology Council (TTC) has committed to e-invoicing compatibility.
