What Is Net 30?
Full payment is due within thirty calendar days of the invoice date.
Detailed Explanation
It is a standard B2B default. Weekend and holiday handling may follow contract or local practice.
Example
Invoice dated March 1 is due by March 31 under Net 30.
Why It Matters
Sets clear expectations and DSO benchmarks.
Key facts
- Net 30 means the buyer must pay within 30 calendar days of the invoice date — not 30 business days unless the contract says so.
- U.S. small-business surveys (NFIB, 2026) show roughly 60% of B2B invoices are issued on net-30 terms despite a national average days-sales-outstanding (DSO) of 38 days.
- Atradius' 2026 Payment Practices Barometer reports that 49% of U.S. B2B invoices on net-30 terms are paid late by an average of 14 days.
- Net 30 is the most common starting term for new vendors; many enterprise customers will push for net-60 or net-90 once a relationship is established.
How it shows up in practice
A boutique design agency in Austin invoices a SaaS client $12,400 for a brand refresh on March 3 with net-30 terms. Payment is contractually due April 2. The client's AP team typically processes invoices in 25–32 days, so the agency builds 35-day collection windows into its cash forecast and sets a friendly reminder for day 28 to keep the invoice top-of-mind without seeming pushy.
Common mistakes
- Counting 30 business days when the contract says calendar days — or vice versa.
- Starting the clock from the receipt date rather than the invoice date (or vice versa) without specifying which on the invoice.
- Offering net-30 by default to brand-new customers without a deposit or credit check.
- Failing to define what counts as 'received' — emailed PDF, mailed paper, or uploaded to a portal.
- Not stating a late-fee policy, so net-30 quietly becomes net-45 with no recourse.
Frequently asked questions
Is net 30 calendar days or business days?
Calendar days unless your contract or invoice explicitly says business days. Always state which on the invoice to avoid disputes.
Should I offer net 30 to new clients?
Generally not without a deposit, credit check, or a smaller initial engagement. Many small businesses require net-15 or 50% deposit on first projects and graduate to net-30 once a payment history is established.
What's the difference between net 30 and 2/10 net 30?
Net 30 means full payment in 30 days. 2/10 net 30 adds a 2% early-payment discount if paid within 10 days, otherwise full amount due in 30 days.
Can I charge a late fee if a net-30 invoice isn't paid on time?
Yes if the contract or invoice states the late-fee terms. Common practice is 1.5% per month (18% APR), enforceable in most U.S. states. Without prior notice, late fees are harder to enforce.
Does net 30 start from invoice date or receipt date?
Most commonly from the invoice date. Some industries (especially construction and government contracting) start from the receipt date. State which on the invoice.
