Understanding Payment Terms (Net 30, Net 15, and More)
Module 1: Accounts Receivable Fundamentals, Chapter 5
The short answer
Payment terms set the deadline for when an invoice is due. "Net 30" means payment is due 30 days after the invoice date, not 30 days after the work was finished. The terms you choose directly shape your DSO, since your target collection speed can never be faster than the terms you've actually offered.
What do the common terms actually mean?
| Term | What it means |
|---|---|
| Due on Receipt | Payment expected immediately upon receiving the invoice |
| Net 15 | Payment due 15 days after the invoice date |
| Net 30 | Payment due 30 days after the invoice date, the most common B2B default |
| Net 60 | Payment due 60 days after the invoice date, common in construction and larger enterprise contracts |
| 2/10 Net 30 | A 2% discount if paid within 10 days, full amount due by day 30 |
Why does "Net 30" confuse people?
Because it's measured from the invoice date, not the date work was completed, and not from when the client received or opened the invoice. If a job finishes on a Monday but the invoice doesn't go out until Friday, the Net 30 clock doesn't start until Friday, four days have already been quietly added before payment terms even begin. This is exactly why invoicing promptly matters as much as the terms themselves.
Do early payment discounts actually work?
Often, yes. A "2/10 Net 30" structure, a 2% discount for paying within 10 days instead of 30, has been shown to reduce DSO by an average of about 12 days. The discount itself is a small cost; carrying that receivable for an extra two to three weeks often costs more in lost cash flow than the discount does.
How do you actually choose the right terms?
- Smaller invoices can often support tighter terms, Net 15 or even Net 7, since the amount at risk is lower and clients rarely object.
- New clients without payment history are a reasonable place to start with shorter terms or a deposit, then loosen once trust is established.
- Industry norms matter. Net 60 is close to standard in construction and some enterprise contracts; insisting on Net 15 there may just cost you the deal without actually getting paid any faster.
Should the due date ever just say "Net 30"?
No, always write the actual calendar date. An invoice that reads "Due December 14, 2026" leaves no room for a client to claim confusion about when payment was owed. "Net 30" alone requires the reader to do the math themselves, and ambiguity is exactly what a slow-paying client benefits from.

Three questions. No email required, this one's just for you.
1. An invoice dated March 1 has Net 30 terms. When is it due?
2. What does "2/10 Net 30" mean?
3. Why should a due date be written as an actual calendar date instead of just "Net 30"?
Frequently asked questions
Are longer payment terms ever a competitive advantage?
Sometimes, in industries or deals where longer terms are expected, offering them can win business. The tradeoff is a structurally slower DSO, which needs to be planned for, not just accepted as a surprise later.
Can payment terms differ by client?
Yes, and often should. A long-standing, reliable client and a brand-new one don't need to be offered identical terms.
Is Net 30 the global standard?
It's the most common U.S. B2B default, but norms vary. Construction commonly runs longer (45-90 days); some retail and smaller invoices run shorter.
