E-invoicing for the United States — from Peppol BIS to IRS 1099.
American invoicing sits across three regimes: voluntary Peppol BIS adoption led by the Business Payments Coalition, the IRS 1099-NEC reporting machine that runs every January, and the post-Wayfair patchwork of 45+ state sales-tax authorities. This center consolidates eight guides — anchored to IRS, Treasury, the Federal Reserve, and state DOR practice — on Peppol BIS, ACH and card rails, 1099 electronic filing, economic nexus, multi-state remittance, QuickBooks / NetSuite / Xero migration, and USMCA cross-border.
