How it’s calculated
Net terms count calendar days from the invoice date: Net 30 = invoice date + 30 days. EOM means the end of the invoice month; Net 30 EOM is 30 days after that. If the due date lands on a Saturday, Sunday or federal holiday, many businesses treat the next business day as the deadline — choose what your contract says.
An early-payment discount such as 2/10 net 30 lets the buyer take 2% off if they pay within 10 days. Skipping it means paying 2% more to keep the money 20 extra days; as a yearly rate that is 2 ÷ 98 × 365 ÷ 20 ≈ 37%.
Worked example with your numbers
- An invoice dated November 13, 2026 with Net 30 terms is due on Monday, December 14, 2026, 31 days after the invoice date.
