Quick answer
Net 30 business days is longer than net 30 calendar days because Saturdays and Sundays are skipped. Public holidays can push the due date out even further if they are excluded.
Calendar days vs business days
A normal net 30 invoice is often interpreted as 30 calendar days. Net 30 business days is different. It counts working weekdays only, which means the final date can be around six weeks after the invoice date depending on weekends and holidays.
How to calculate it
Choose the invoice date as the start date, count 30 working days, then decide whether to exclude public holidays. For exact payment disputes, always check the contract wording and local rules.
Before you rely on the date
