Direct answer
Use the date named in the payment terms. Net 30 usually starts from the invoice date, but some agreements start the clock after receipt, approval, or acceptance.

Open Business Days From Today CalculatorRealistic scenario
A vendor may send an invoice on Monday, the client may receive it Tuesday, and approval may happen Friday. If the agreement is vague, both sides can land on different due dates.
Invoice date: June 1. Approval date: June 5. Terms: Net 30 after approval. Due date uses June 5 as the start event, not June 1.
Calculation frame
Due date = named start date + 30 calendar days unless the agreement says business days.

How to check it
Key checks
- Find the exact payment-term wording.
- Identify whether the start event is invoice, receipt, approval, or acceptance.
- Use calendar days unless business days are stated.
- Do not count from two different dates in the same estimate.
- Record the start-date assumption with the result.
Details people usually miss
Plain Net 30 is commonly treated as calendar days from the invoice date.
Approval-based terms are common when the client needs to confirm work before the payment clock starts.
If the document says 30 business days, weekends and excluded holidays can push the date much later.
Common mistakes
Do not assume approval date controls unless the terms say it does.
Do not use business days for ordinary Net 30 unless stated.
Do not hide the start date when sending the due date.
