Direct answer
If the contract says Net 45 business days, add 45 business days from the invoice or approval date and skip weekends and listed holidays. If it only says Net 45, confirm whether it means calendar days.

Open Business Days From Today CalculatorReal workplace situation
Net terms are often written casually, but 45 calendar days and 45 business days can land more than two weeks apart. The invoice wording decides the count.
Invoice approved Monday, March 2. Terms: Net 45 business days. Count 45 weekdays forward, excluding holidays. The due date is later than a 45-calendar-day due date.
Working rule
Net 45 business-day due date = start date + 45 business days, excluding weekends and applicable holidays.

Checklist before you rely on the number
Key checks
- Read whether the terms say calendar days or business days.
- Identify the start date: invoice date, approval date, or receipt date.
- Add holidays or closures if the agreement excludes them.
- Calculate the due date.
- Save the wording beside the date.
Practical notes
Many invoices use calendar days by default, so business days should be confirmed when the wording is unclear.
Approval date and invoice date can be different; the agreement decides which one starts the clock.
If the due date lands on a closure, payment timing may follow the next business day.
Mistakes that change the result
Do not assume Net 45 means business days.
Do not start from the wrong event date.
Do not forget holidays if the contract excludes non-business days.
