What Does Net 30 Mean?
Net 30 means an invoice is due for payment 30 calendar days after the date it was issued. It's one of the most common payment terms on New Zealand trade invoices, and the "30" always counts from the invoice date, not the delivery date or the end of the month.
What Net 30 Means
"Net" simply means the full invoice amount, with no early-payment discount attached. The "30" is the number of days the customer has to pay, counted from the invoice date. So Net 30 on an invoice dated 3 March means payment is due 30 days later, on 2 April.
This is different from terms tied to the calendar month, such as EOM 30 or 20th of the month following, where the due date depends on which month the invoice falls in rather than a fixed number of days after issue.
Worked Example
| Invoice Date | Net 30 Due Date |
|---|---|
| 3 March | 2 April |
| 15 March | 14 April |
| 28 March | 27 April |
Unlike EOM-style terms, every invoice under Net 30 gets the same 30-day window, regardless of when in the month it's raised.
Net 30 vs EOM 30 vs "20th of the Month Following"
| Term | How the due date is set | Typical wait |
|---|---|---|
| Net 30 | 30 days after the invoice date | 30 days, every time |
| EOM 30 | 30 days after the end of the invoice month | 31 to 60 days, depending on invoice date |
| 20th of the month following | The 20th of the next calendar month | About 20 to 50 days, depending on invoice date |
Why Suppliers Use Net 30
Net 30 is predictable and easy to apply consistently across every invoice, which is why it's the default starting point for many NZ trade accounts. It gives the customer a clear, fixed window to organise payment, and it's simple for a supplier's accounting system to track and chase automatically.
Is Net 30 Negotiable?
Yes. Net 30 is a starting point, not a fixed rule, and many suppliers will shorten or lengthen it depending on the customer's credit history, order size, or how established the relationship is. A new customer might start on Net 7 or COD and move to Net 30 once a payment history is established; a large, reliable customer might negotiate Net 60 instead.
For suppliers who find Net 30 ties up too much cash, PaidTerms Capital pays the invoice upfront while the customer repays over an agreed schedule, so the supplier doesn't have to choose between offering terms and waiting 30 days to get paid.
Frequently Asked Questions
Does Net 30 include weekends and public holidays?
Yes. Net 30 counts calendar days, not business days, so weekends and public holidays are included in the 30-day count.
What happens if a customer pays after Net 30?
The invoice becomes overdue. Many suppliers follow up with a reminder first, and some terms of trade allow interest or a late fee to be charged on overdue balances.
Is Net 30 the same as 30 days from invoice date?
Yes, they mean the same thing. "Net 30" and "30 days net" are two common ways of writing the identical term.
Is Net 30 common in New Zealand?
Yes, it's one of the most widely used payment terms on NZ trade and wholesale invoices, alongside calendar-based terms like EOM 30 and the 20th of the month following.
Can a supplier charge interest for late Net 30 payment?
Only if the terms of trade the customer agreed to allow it. It isn't automatic just because a payment is late.
