Net 30 vs Net 15: Which Payment Terms Should You Use?

What’s the Difference Between Net 30 and Net 15?

Net 30 means payment is due 30 days after the invoice date. Net 15 means payment is due within 15 days. The number refers to calendar days, not business days, unless you clearly state otherwise in your payment terms.

Net 30 has long been the standard in B2B invoicing because it gives companies time to route invoices through their accounts payable systems. Net 15 is increasingly common among freelancers and small businesses that need faster cash flow. In many service industries, especially when working with small businesses or individuals, Net 7 is now a typical option as well.

How Payment Terms Affect Your Cash Flow

Payment terms have a direct impact on how quickly money comes into your business.

For example, if you invoice $10,000 per month and move from Net 30 to Net 15, you collect that money two weeks sooner on average. For many small businesses, that difference can determine whether payroll, expenses, or supplier payments are covered comfortably.

Shorter payment terms also reduce the risk of unpaid invoices. An invoice that is 15 days old is usually much easier to collect than one that has been sitting unpaid for 45 days or longer.

When to Use Net 30

Net 30 tends to work best when clients need additional time to process payments. It is commonly used in situations such as:

• Large corporate or government clients that require Net 30 by policy
• Companies with formal accounts payable departments that process invoices in batches
• Large project invoices where the client needs time to arrange payment
• Long-term client relationships where payment history is already reliable

When to Use Net 15

Net 15 is often better suited for smaller businesses or service providers who need quicker payment.

Common situations include:

• Working with SMB clients or individual business owners
• Retainer relationships where monthly billing is predictable
• Projects where you want faster payment without shortening terms all the way to Net 7

How to Negotiate Shorter Payment Terms

If a client asks for Net 30 but you prefer Net 15, there are a couple of practical ways to handle it.

First, present Net 15 as your standard payment term from the beginning. Clients are less likely to push back when it is framed as your normal billing practice rather than a special request.

Second, consider offering an early payment discount. For example:
“2% discount if paid within 7 days, otherwise Net 30.”
