"Net 30" is printed on millions of invoices, yet many small business owners are not sure what it commits them to. Here is what the term means, how the dates work and when a different arrangement serves you better.

What does Net 30 mean?

Net 30 means the full invoice amount is due within 30 days of the invoice date. An invoice dated June 1 with Net 30 terms is due on July 1. "Net" refers to the full net amount owed; the number is the count of days. Net 15, Net 45, Net 60 and Net 90 follow the same pattern.

Unless your agreement says otherwise, the clock starts on the invoice date, not on the day the client receives or approves the invoice. This is why sending invoices promptly matters: a late invoice means a late due date.

Why Net 30 is so common

Larger companies run payment cycles around fixed schedules, and 30 days fits comfortably into a monthly cycle. Many accounts payable teams default to Net 30 (or longer) unless a contract says otherwise. For you as the seller, it is a reasonable middle ground, but not necessarily the best one for a small business with bills of its own.

Common payment terms compared

  • Due on receipt: payment expected immediately. Best for small jobs and consumers.
  • Net 7 / Net 15: short windows that keep cash flowing. Popular with freelancers and trades.
  • Net 30: the usual standard in B2B.
  • Net 60 / Net 90: demanded by some large clients. Hard on your cash flow, so price accordingly.
  • Deposit + balance: for example 50% upfront and 50% on completion. Ideal for larger projects.
  • Milestone billing: invoice at agreed stages of a long project.

What is "2/10 Net 30"?

This early payment discount means the client can deduct 2% if they pay within 10 days; otherwise the full amount is due in 30. It can speed up payment, but 2% for paying 20 days sooner is a high annualized cost to you. Work out whether it is worth it with the discount calculator before offering it.

How to calculate the due date

Add the number of days to the invoice date. It is easy to slip by a day or two across month ends, so use the due date calculator and write the exact date on the invoice, not only "Net 30". A visible date removes any argument.

Protecting yourself on longer terms

  • Ask for a deposit from new clients.
  • Invoice immediately when work is done.
  • State a late-fee policy on the invoice and in your contract (see the late fee calculator).
  • Follow up the day after the due date. Our guide on overdue invoices shows how.

Frequently asked questions

Is Net 30 legally binding?

It is binding when both sides agreed to it, for example in a contract, quote or accepted invoice. Put the terms in writing before work starts.

Can I change the terms for one client?

Yes. Terms are negotiable. If a client needs longer, you can accept it in exchange for a deposit, a higher price or a late-fee clause.

What if the due date falls on a weekend?

Many businesses pay on the next business day, but agree that in advance if timing is tight.
