Net 30 means the client has 30 calendar days from the invoice date to pay the full amount. It is the most common payment term used by small businesses and freelancers in the US.

What is the best payment term for a small business?

Due on Receipt or Net 15 work well for service businesses because they speed up cash flow. Net 30 is standard but can create cash flow gaps for new businesses. Choose terms that work for your industry and client relationship.

Invoice Payment Terms — What They Mean and How to Set Them.

What are invoice payment terms?

Payment terms are the conditions you set for when and how a client should pay your invoice. They are usually written near the total amount on the invoice and look something like:

Net 30 — Payment due within 30 days
Net 15 — Payment due within 15 days
Due on Receipt — Payment due immediately
2/10 Net 30 — 2% discount if paid within 10 days, otherwise full amount due in 30 days

Common payment terms explained

Net 30

The standard in many US industries. The client has 30 calendar days to pay from the invoice date. While common, it can create cash flow delays if you have multiple clients on Net 30 terms. Many freelancers and small service businesses are moving away from Net 30 toward shorter terms.

Net 15

A faster version of Net 30. Good for project-based work where you want to get paid sooner without being aggressive. Many contractors and field service businesses use Net 15.

Due on Receipt

Payment is expected as soon as the client receives the invoice. This works well for:

One-off jobs with new clients
Small invoice amounts
Industries where immediate payment is the norm

2/10 Net 30

An incentive structure: the client gets a 2% discount if they pay within 10 days. Otherwise, the full amount is due in 30. Large companies use this to encourage early payment, but it is less common for small service businesses.

How to choose the right terms

Consider these factors:

Your cash flow needs — If you need money coming in quickly, shorter terms (Due on Receipt or Net 15) help.
Industry norms — Check what competitors and peers in your field use. Following norms reduces friction.
Client relationship — Long-term, trusted clients might get Net 30. New clients might start with Net 15 or Due on Receipt.
Invoice amount — Larger invoices (thousands of dollars) often have Net 15 or Net 30. Smaller invoices can reasonably be Due on Receipt.

Late payment policy

Every invoice should include your late payment policy. Without one, clients have no incentive to pay on time. A simple policy looks like:

"Payment is due within 15 days. A late fee of 1.5% per month will be applied to overdue balances."

State this on the invoice itself so there is no confusion. You can also send polite payment reminders before and after the due date.

Setting terms in your invoice tool

A good invoice app lets you set default payment terms and override them per invoice. In SpeakBill, you can include payment terms in the notes section of each invoice and edit them as needed. The key is consistency — your clients should know what to expect every time they receive an invoice from you.
