What Are Invoice Payment Terms?
Invoice payment terms are the agreed conditions under which a client is expected to pay — specifically, the deadline and any consequences for missing it. They appear on every professional invoice and form part of your binding agreement with the client.
Clear payment terms protect you legally, set expectations before disputes arise, and give you a documented basis for follow-up if a client pays late. Without them, you have no anchor date for follow-up and no contractual standing for late fees.
The most common payment terms used by freelancers and small businesses are:
- Due on Receipt: Payment expected as soon as the client receives the invoice. Often written as "Payment due immediately."
- Net 15: Payment due within 15 calendar days of the invoice date.
- Net 30: Payment due within 30 calendar days of the invoice date. The most widely used standard in corporate environments.
- Net 45 / Net 60: Common with government agencies, large enterprises, and international clients. Acceptable only when the project size or relationship justifies the wait.
- 2/10 Net 30: The client gets a 2% discount if they pay within 10 days; otherwise, the full amount is due within 30 days. Encourages early payment from clients who are financially motivated to act quickly.
- End of Month (EOM): Payment due at the end of the calendar month in which the invoice was issued. Less common for freelancers but used in some industries.
Net 30 vs Net 15 vs Due on Receipt: Which Is Best?
The short answer: Net 15 is the best default for most freelancers. According to a Xero small business report, invoices issued with Net 15 terms are paid an average of 10 days earlier than those with Net 30 terms. That difference compounds significantly over a year of invoicing.
| Terms | Best For | Pros | Cons |
|---|---|---|---|
| Due on Receipt | Small amounts, long-term clients | Fastest possible payment | Can feel aggressive with new clients |
| Net 15 | Most freelance projects | Fast, widely accepted | Some corporate clients may push back |
| Net 30 | Corporate and enterprise clients | Matches corporate AP cycles | Slow; 30+ days is common actual payment time |
| 2/10 Net 30 | Large invoices, financially-driven clients | Incentivizes early payment | Costs 2% if taken; adds complexity |
| Net 60 | Government, large enterprise only | Required for some large contracts | Seriously hurts cash flow |
The practical recommendation by client type:
- Independent / small business clients: Net 15 or Due on Receipt
- Mid-size companies: Net 15; accept Net 30 if required
- Enterprise or government: Net 30-60 depending on their AP cycle
- Retainer clients (ongoing): Net 15, invoiced on the same day each month
How to Add Payment Terms to Your Invoice
Payment terms should appear in two places on your invoice: as a calculated due date in the header ("Due: April 16, 2026") and as a written statement in your terms section. Both are necessary — the date is what clients look at first; the written terms are your legal record.
Here are exact wording examples you can copy directly:
Standard Net 15:
"Payment is due within 15 days of the invoice date. Late payments are subject to a 1.5% monthly interest charge on the outstanding balance after the due date."
Net 30 with early payment incentive:
"Payment is due within 30 days of the invoice date. A 2% discount applies if payment is received within 10 days."
Retainer / recurring:
"This invoice covers services rendered in [Month] [Year]. Payment is due by the 15th of the following month. Continued services are contingent on account being current."
In Due On Time, enter these in the Terms & Conditions field at the bottom of the invoice form. They appear on every PDF you generate and are saved as your default for future invoices once you create an account.

What Happens When a Client Ignores Payment Terms?
When a client misses a due date, the right response is a structured follow-up sequence — not silence. Most overdue invoices are paid within 30 days of the due date once a reminder sequence begins. The clients who genuinely refuse to pay without escalation are a small minority.
The escalation timeline that works:
- Day 1-3 past due: Polite email with invoice reattached, asking if everything looks correct
- Day 10 past due: Firm reminder citing the due date and requesting a payment date
- Day 20 past due: Written notice that late fees now apply and you are considering further action
- Day 30+ with no response: Formal letter, small claims court, or collections depending on amount
The best approach is to automate reminders so you never have to have the awkward conversation manually. Due On Time's Starter plan sends this sequence automatically — you set it once per invoice and the system handles the follow-up.

Regional Payment Term Standards
Payment norms and legal frameworks vary by region. Here is what you need to know if you work with clients internationally:
UAE: Standard commercial payment terms are 30 days, though government clients and large corporations often operate on 45-60 day cycles. There is no statutory late payment interest rate in the UAE, so your contractual terms are the only protection you have — always include a late fee clause.
EU — Late Payment Directive: The EU Late Payment Directive (2011/7/EU) automatically entitles you to statutory interest after 30 days on B2B transactions, even without a contractual clause. The rate is the European Central Bank's reference rate plus 8 percentage points. You are also entitled to claim reasonable recovery costs.
Canada and US: Net 30 is the standard across most industries, but Net 15 is increasingly common among freelancers and small businesses. There is no statutory late payment interest in most US states or Canadian provinces — your contractual clause is your only recourse, so always include one.
UK: The Late Payment of Commercial Debts Act entitles you to statutory interest of 8% over the Bank of England base rate on overdue B2B invoices. You can also claim reasonable collection costs. This applies automatically — you do not need a contractual clause, though having one reinforces your position.
