Is Net 15 too short for most clients?

For individual clients and small businesses with simple payment processes, Net 15 is very manageable. For large corporations with formal accounts payable cycles, Net 30 or Net 45 may be more practical. Know your client type before setting terms.

When does the Net 15 period start?

Net 15 typically starts on the invoice date. Some contracts specify it starts on delivery of goods or completion of services. Clarify in your contract to avoid confusion: 'Payment is due 15 days from the invoice date.'

What is the difference between Net 15 and due upon receipt?

'Due upon receipt' (Net 0) means payment is expected immediately when the client receives the invoice. Net 15 gives clients 15 days. In practice, most clients treat both terms similarly -- they pay when they get around to it -- so a late payment policy is essential for both.

Can I offer a discount for early payment with Net 15 terms?

Yes. A common structure is '2/5 Net 15' -- the client receives a 2% discount if they pay within 5 days; otherwise, the full amount is due in 15 days. This incentivizes the fastest possible payment.

How do I enforce Net 15 if a client always pays on day 20 or 30?

Apply your late payment clause consistently -- add the stated fee for every day beyond day 15. This signals that your terms are serious. For chronically late clients, consider requiring a deposit before future projects begin.

What does Net 15 mean?

Net 15 means full payment is due 15 calendar days after the agreed starting date, usually the invoice date.

How do you calculate a Net 15 due date?

Add 15 calendar days to the agreed start date. For example, an invoice dated July 1 is due July 16.

Is Net 15 the same as 15 business days?

Net 15 normally means calendar days. If the agreement intends business days, state that explicitly and print the exact due date.

What is the difference between Net 15 and Net 30?

Net 15 gives the customer 15 calendar days to pay, while Net 30 gives the customer 30 calendar days.

What is Net 15?

Net 15 means payment is due within 15 days of the invoice date. It offers a middle ground between Net 7's speed and Net 30's flexibility. Learn when Net 15 is the right choice and how to enforce it.

Net 15 payment terms

Net 15 means payment is due within 15 calendar days.

The 15-day period usually starts on the invoice date unless the contract defines another trigger, such as receipt or approval. Print the exact due date beside Net 15 so the customer does not need to calculate it.

Due-date example

An invoice dated July 1, 2026 with Net 15 terms is due July 16, 2026.

Invoice wording

Payment terms: Net 15. Full payment is due July 16, 2026.

Net 15 vs Net 30

Net 15 provides 15 calendar days to pay; Net 30 provides 30 calendar days.

Best practice

Agree the term before invoicing and show the invoice date, exact due date, accepted payment methods, and late-payment policy.

Net 15 is a payment term that requires the invoice recipient to pay the full outstanding balance within 15 calendar days of the invoice date. The term 'net' refers to the net amount due -- the total payable after any discounts or adjustments. Net 15 is one of the shorter standard payment terms used in business, sitting between 'due upon receipt' (or 'Net 0') and the more common Net 30. For freelancers and small business owners, Net 15 is an excellent default payment term because it accelerates cash collection while remaining reasonable for clients with internal payment processes. Compared to Net 30 or Net 60, Net 15 cuts your average receivables period in half, improving cash flow substantially. For clients who frequently pay close to the due date, shortening terms from Net 30 to Net 15 means the same invoice gets paid two weeks sooner -- a meaningful difference when you are managing monthly expenses.

Net 15 is activated on the invoice date (or sometimes the delivery date of goods or services, depending on the agreement). If you invoice a client on June 1 with Net 15 terms, payment is due by June 16. If payment arrives on June 17, it is one day late and any late payment clause in your contract becomes applicable. Net 15 is stated clearly on the invoice in the payment terms field: 'Payment due within 15 days of invoice date' or simply 'Net 15.' Many invoicing platforms allow you to set a default payment term that automatically calculates and displays the due date when you create an invoice. For clients with formal accounts payable departments, Net 15 may conflict with their standard payment cycles (often monthly or bi-weekly), so it is worth confirming the client can accommodate the term before establishing it as your default.

Net 15 is a practical choice for freelancers working with small to medium-sized business clients. Individual clients and small businesses typically have the ability to process payments within 15 days. For sole proprietors, Net 15 combined with online payment options (credit card, ACH through invoicing software) often results in average payment in 7-10 days, since many clients pay immediately when they receive a clear, easy-to-pay invoice. The psychological effect is also worth noting: a 15-day deadline creates more urgency than a 30-day deadline. Clients who see 'Due: June 16' are more likely to process payment promptly than those who see 'Due: June 30' and feel no urgency for weeks. For services with clear, definitive deliverables (a completed website, a finished report), Net 15 is particularly appropriate -- the client has what they paid for and there is no reason to delay.

Net 30 is the most common standard payment term in US business -- it gives clients 30 days to process payment, which accommodates most corporate payment cycles. Net 15 is twice as fast, which improves your cash flow but may not align with all clients' payment capabilities. The right choice depends on your client type: for individual clients and small businesses, Net 15 is typically manageable. For corporate clients with formal accounts payable processes, Net 30 or even Net 45 may be more realistic. A useful strategy: set Net 15 as your default and negotiate to Net 30 for clients who specifically request it, rather than defaulting to Net 30 and trying to push everyone toward faster payment. This anchors client expectations around faster payment while remaining flexible for those with genuine process constraints.

Step 1: State Net 15 in your client contract or engagement letter: 'Invoices are payable within 15 calendar days of the invoice date.' Step 2: Include the payment term prominently on every invoice, along with the calculated due date. Step 3: Pair Net 15 with a late payment clause (e.g., 1.5% per month on balances outstanding more than 15 days from invoice date). Step 4: Send invoices promptly after project completion or at the end of the billing period -- the 15-day clock starts on the invoice date, so delays in sending reduce your urgency advantage. Step 5: Include online payment options to make immediate payment easy. Step 6: Send automated reminders at day 10 (5 days before due) and day 16 (1 day overdue) to maintain the payment cycle without manual effort. Step 7: Apply your late payment policy promptly when due dates pass.

Eonebill is built to support faster payment terms like Net 15 by automating the follow-up process that makes short payment windows work. When you set Net 15 as your default, Eonebill calculates the due date automatically and sends your configured reminder sequences -- before the due date and after -- without any manual effort. The [free invoice generator](/free-tools/invoice-generator) creates invoices with Net 15 prominently displayed, and online payment links give clients the ability to pay immediately upon receipt. [Eonebill pricing](/pricing) plans include payment tracking that shows which invoices are approaching their 15-day window and which have passed it, so you can manage your receivables proactively. By automating the Net 15 cycle from invoice to reminder to payment, Eonebill makes short payment terms practical and effective.

1. Using Net 15 for clients whose payment processes cannot accommodate it: a corporate client with a bi-monthly check run cannot pay Net 15; negotiate terms that fit their process to avoid perpetual late payments. 2. Not stating the due date explicitly: 'Net 15' may be misunderstood; include the calculated due date (e.g., 'Due: June 16, 2025') to remove any ambiguity. 3. Not pairing Net 15 with a late payment policy: short terms without enforcement create no actual urgency benefit. 4. Sending invoices late: if you issue an invoice 5 days after project completion, you have given up 5 days of your 15-day window; invoice promptly. 5. Allowing clients to consistently pay on day 14-15 without issue when earlier payment is needed: if your cash flow requires payment in 10 days, consider Net 10 terms or request a partial deposit upfront.
