Net 30 Due Date Calculator

What Are Net Payment Terms?

Net payment terms define how many days a client has to pay an invoice from the invoice date. "Net 30" simply means the full invoice amount is due within 30 calendar days. These terms are one of the most important — and most misunderstood — parts of business-to-business invoicing.

The word "net" comes from accounting and refers to the total amount due after any applicable discounts. When you write "Net 30" on an invoice, you're telling your client: pay the full amount within 30 days of today's date. No discount, no special conditions — just a clear payment deadline.

Common Payment Terms and What They Mean

Term	Meaning	Best For
Due on Receipt	Payment expected immediately upon receiving the invoice	Small jobs, new clients, retail
Net 7	Payment due within 7 calendar days	Short-term projects, digital deliverables
Net 15	Payment due within 15 calendar days	Freelancers wanting faster cash flow
Net 30	Payment due within 30 calendar days	Standard B2B invoicing, most industries
Net 45	Payment due within 45 calendar days	Larger companies with longer AP cycles
Net 60	Payment due within 60 calendar days	Enterprise clients, government contracts
Net 90	Payment due within 90 calendar days	Large corporations, international trade
2/10 Net 30	2% discount if paid in 10 days, full amount due in 30	Encouraging faster payment from slow payers

Net 30: Calendar Days or Business Days?

This is one of the most common points of confusion in invoicing. Standard Net 30 means 30 calendar days — weekends and holidays count. If you want business days instead, you need to write that explicitly on your invoice: "Net 30 business days" or "30 working days from invoice date."

Most freelancers and small businesses use calendar days because it's simpler to calculate and less open to interpretation. If you tell a client "Net 30" and they assume business days, they could be holding your payment an extra two weeks without technically being late by their reading.

Pro tip: Always state your terms clearly

Don't just write "Net 30" — include the actual due date on every invoice. Something like "Net 30 — Payment due May 20, 2026" removes all ambiguity and gives the client a concrete date to work toward. Our Invoice Generator does this automatically.

How Early Payment Discounts Work (2/10 Net 30)

An early payment discount is a way to incentivize clients to pay faster by offering a small discount if they pay before the standard due date. The format looks like this: 2/10 Net 30.

Breaking it down: the first number (2) is the discount percentage. The second number (10) is the number of days the client has to take advantage of that discount. "Net 30" is still the standard due date if they don't take the discount. So 2/10 Net 30 reads as: "Take 2% off if you pay within 10 days — otherwise the full amount is due in 30 days."

For the client, the effective annual return on that 2% discount over 20 saved days is roughly 36% — which is why many well-run businesses will always take early payment discounts when offered. For you as the seller, losing 2% to get paid 20 days faster can be well worth it if you have cash flow needs or are tired of chasing late payments.

What Payment Terms Should Freelancers Use?

There's no universal answer, but here are the most common approaches among freelancers and small service businesses:

Net 15 is increasingly common among freelancers who want to maintain healthy cash flow. Most individual clients and small businesses can pay within 15 days without issue.
Net 30 is the standard for larger companies and corporate clients, who often have accounts payable processes that make anything faster difficult.
50% upfront, balance Net 15 is a popular structure for project-based work. It eliminates the risk of non-payment and front-loads your cash flow.
Due on Receipt is fine for small, one-time jobs — especially when the client is present when the work is done (think: photography sessions, tutoring, trades work).

Whatever terms you choose, the most important thing is to be consistent and to state them clearly on every invoice. Clients are less likely to dispute or delay a payment when the terms are unambiguous from the start.

Late Fees: Protecting Yourself When Clients Pay Late

Including a late fee policy on your invoices gives you leverage when a client misses their due date. A standard late fee is 1.5% per month on the outstanding balance (which works out to 18% annually). Some freelancers charge a flat fee like $25 or $50 for any invoice that goes more than 30 days past due.

To enforce a late fee, it needs to appear on your invoice or contract before the work begins. You can't add a late fee policy after the fact and expect it to hold up. Include a line like: "Invoices unpaid after 30 days are subject to a 1.5% monthly late fee." Our Invoice Generator has a notes field where you can add this language.

Frequently Asked Questions

What does Net 30 mean on an invoice?

Net 30 means the full invoice amount is due within 30 calendar days of the invoice date. It is one of the most common payment terms used in business-to-business invoicing. The word "net" refers to the total amount owed after any discounts.

Does Net 30 mean 30 business days or calendar days?

Net 30 means 30 calendar days unless your contract or invoice explicitly states "business days." Most standard invoicing uses calendar days. If you want 30 business days, you would need to write that explicitly in your payment terms.

What is 2/10 Net 30?

2/10 Net 30 is an early payment discount term meaning: take a 2% discount if you pay within 10 days, otherwise the full amount is due within 30 days. The first number is the discount percentage, the second is the discount window in days, and Net 30 is the standard due date.

What payment terms should I use as a freelancer?

Most freelancers use Net 15 or Net 30. Net 15 is better for cash flow but some larger clients expect Net 30 as standard. For new clients or large projects, consider requiring a 50% deposit upfront with the balance due Net 15 on delivery.

What happens if a client pays late?

If a client pays after the due date, you are generally entitled to charge a late fee if your invoice or contract specifies one. Common late fees are 1.5% per month on the outstanding balance. Always include your late fee policy on your invoices so clients are aware before they agree to work with you.

Can I change my payment terms for different clients?

Yes — your payment terms are entirely up to you. Many businesses use shorter terms (Net 15) for newer or smaller clients and offer Net 30 or Net 45 to long-standing enterprise clients with established track records. You can negotiate terms as part of your overall client agreement.
