Net 30 is one of the most common billing terms in business, but many freelancers use it without fully thinking through the implications for their cash flow and client relationships.
What net 30 actually means
“Net” in billing terminology refers to the net amount due — the total after any early payment discounts. “30” is the number of days. So net 30 simply means: the full amount is due 30 days from the invoice date.
A net 30 invoice sent on June 1 is due July 1. If July 1 passes without payment, the invoice is overdue. At that point, any late fee clause in your contract begins to apply.
The term appears on the invoice itself, usually in the payment terms line. Common related terms include net 15 (15 days), net 60 (60 days), and due on receipt (payment expected immediately).
When net 30 makes sense
Net 30 billing fits best when:
- You are working with corporate clients who have formal accounts payable processes that require 30-day cycles
- The project is large enough that a 30-day payment delay doesn’t strain your cash flow
- The client has a reliable payment history and you trust the terms will be honored
For one-off or small projects, net 30 is often too generous. You finish work in a week, wait 30 days, and the cash hits 5-6 weeks after the project started.
Net 30 is a standard, not a requirement. Freelancers who use net 15 by default — and only extend net 30 when clients specifically request it — get paid twice as often in the same time period.
When net 30 works against you
The disadvantage of net 30 is straightforward: it is a 30-day interest-free loan to your client. They get your work immediately and have a month to pay for it. For clients who respect due dates, this is fine. For clients who treat your due date as a suggestion, net 30 quickly becomes net 45 or net 60 in practice.
If you have clients who routinely pay late under net 30 terms, consider switching to net 15 for future work. The change rarely ends relationships — it often just prompts clients to pay on time instead of late.
How to specify net 30 on invoices
Your invoice should include a “Payment Terms” section that states “Net 30” or “Payment due within 30 days of invoice date.” Waco includes this automatically when you set your terms, and displays the due date clearly on the invoice so there is no ambiguity.
Net 30 vs. other common terms
- Net 15: Payment due in 15 days. Better for cash flow, rarely pushes clients away.
- Net 60: Common in larger corporate settings. Tough on freelancer cash flow.
- Due on receipt: Immediate payment expected. Works well for deposits and final milestone invoices.
- 2/10 net 30: 2% discount if paid within 10 days, full amount due within 30. Rarely used by individual freelancers.
