When does Net 30 start: invoice date or delivery date?

Is the invoice date always the start point?

In most cases, yes. The invoice date is the standard trigger because it creates a clear, trackable starting point for payment.

But some contracts may state that Net 30 begins on delivery, completion of services, or even when the invoice is received. Always check the exact wording to confirm.

What should you check to avoid confusion?

Look at both the invoice and the contract terms. If they conflict or are unclear, that can lead to disputes about when payment is actually due. However, the contract usually controls over the invoice. The invoice alone may not modify contract terms.

Clear language about when the payment period starts helps both sides stay aligned and avoid late fees or misunderstandings.

What to do next...

1. Check the invoice date listed on the bill.
2. Review the contract for any different timing rules.
3. Confirm the start date if anything is unclear.
4. Track the due date to avoid late payment.

What to consider in your specific situation

While invoice date is common, your agreement may define timing differently.

• The exact wording in your contract or invoice.
• Whether delivery or completion triggers payment.
• Any delays in receiving the invoice.
• Industry practices for timing payment terms.
• Any prior agreements or billing habits.
