Understanding Net 30 Payment Terms

Net 30 is the most widely used B2B payment term, requiring payment within 30 days of the invoice date. This standard provides buyers with adequate time to process invoices through their accounts payable systems while ensuring sellers receive timely payment.

How It Works

When you issue an invoice with Net 30 terms, the buyer has 30 calendar days from the invoice date to make payment. For example, an invoice dated January 1st with Net 30 terms would be due on Jan 31, 2024.

Common Variations

  • Net 30 EOM: Payment due 30 days after end of month
  • 2/10 Net 30: 2% discount if paid within 10 days
  • Net 30 + COD: Combined terms for partial payment
