Understanding Net 15 Payment Terms

Net 15 is a payment term that gives customers 15 days to pay from the invoice date. This middle-ground option balances seller cash flow needs with buyer convenience, often used in retail, distribution, and service industries.

How It Works

When you issue an invoice with Net 15 terms, the buyer has 15 calendar days from the invoice date to make payment. For example, an invoice dated January 1st with Net 15 terms would be due on Jan 16, 2024.

  • Net 15 EOM: Payment due 15 days after end of month
  • 2/10 Net 15: 2% discount if paid within 10 days
