Net 30 means the total amount of the invoice must be paid within 30 calendar days from the invoice date. It is the most widely used payment term in business-to-business transactions.

What Is Net 30?

"Net" refers to the total amount due after any deductions. "30" is the number of calendar days the client has to pay. So Net 30 simply means: pay the full amount within 30 days.

The countdown starts from the invoice date, not the date the client receives the invoice. If an invoice is dated November 1, payment is due by December 1 regardless of when it arrives.

Variations of Net Terms

  • Net 10 — due in 10 days (common for small or urgent invoices)
  • Net 15 — due in 15 days (popular with freelancers)
  • Net 30 — due in 30 days (the business standard)
  • Net 45 — due in 45 days
  • Net 60 — due in 60 days (common with large enterprises)
  • 1/10 Net 30 — 1% discount if paid in 10 days, otherwise full amount in 30 days
  • 2/10 Net 30 — 2% discount if paid in 10 days, otherwise full amount in 30 days

Example

A consulting firm invoices a client on October 15 for $5,000 with Net 30 terms:

  • Invoice Date: October 15, 2026
  • Payment Term: Net 30
  • Due Date: November 14, 2026
  • Amount Due: $5,000.00

If the invoice instead offered "2/10 Net 30," the client could pay $4,900 ($5,000 minus 2%) by October 25 to take advantage of the early-payment discount.

When to Use Net 30

Net 30 works well when:

  • You are working with established businesses that have regular payment cycles
  • Your cash flow can handle a 30-day wait
  • The invoice amount is moderate to large
  • You want to offer a professional courtesy without extending too much credit

Consider shorter terms (Net 10, Net 15, or Due on Receipt) when:

  • You are working with a new client for the first time
  • The project is small and cash flow is tight
  • You are in an industry where immediate payment is standard (e.g., retail, food service)

Common Mistakes

  • Confusing Net 30 with 30 days from receipt. Net 30 counts from the invoice date, not the delivery date.
  • Not specifying the start date. Always include the invoice date so there is no ambiguity about when the 30 days begin.
  • Offering Net 30 to unreliable clients. If a client has a history of late payment, shorten the terms or require a deposit upfront.
  • Forgetting to follow up. Send a friendly reminder at day 25 to ensure the payment is on track.
