NDN Analytics TeamApril 9, 2026

B2B payments are stuck in the past. Despite digital transformation across every other business function, most companies still chase invoices, reconcile payments manually, and spend months resolving disputes.


The B2B Payments Problem


  • Average DSO (Days Sales Outstanding) is 45+ days
  • 3% of invoices result in disputes
  • Manual reconciliation costs $10-15 per invoice
  • Cash flow uncertainty hampers growth

    • Enter Smart Contract Payments
