What Are Invoice Payment Terms?
Payment terms define when a client must pay an invoice. They appear on every professional invoice and determine your cash flow, your client relationships, and how quickly you can pay your own bills.
The most common formats are Net [days] (e.g., Net 30, Net 60) and Due on Receipt. Some include early-payment discounts: 2/10 Net 30 means a 2% discount if paid within 10 days, otherwise full payment due in 30.
Common Payment Terms Explained
| Term | Due date | Best for | Risk level |
|---|---|---|---|
| Due on Receipt | Immediately | Retail, new clients, quick services | Lowest |
| Net 7 | 7 days | Freelancers, small projects | Low |
| Net 15 | 15 days | Service businesses, regular clients | Low–Medium |
| Net 30 | 30 days | Standard B2B, trusted clients | Medium |
| 2/10 Net 30 | 30 days (2% off if paid in 10) | Encouraging early payment | Medium |
| Net 60 | 60 days | Large corporations only | High |
| Net 90 | 90 days | Enterprise/government (avoid) | Very High |
How to Calculate a Due Date
For Net 30, count 30 calendar days (not business days) from the invoice date. If you invoice on May 1, payment is due May 31. Use the Payment Terms Calculator to get the exact due date and any early-pay discount deadline.
Which Payment Terms Should You Use?
The right payment term depends on three factors:
- Your cash flow. If you have thin reserves, Due on Receipt or Net 7 protects you. Net 30 means waiting a month before you can pay your own bills.
- Your client relationship. New clients get tighter terms. Trusted long-term clients can get Net 30 as a courtesy.
- Industry norms. Advertising agencies expect Net 60. Restaurants expect Net 7. Match the norm or negotiate explicitly.
Late Fee Language That Actually Works
Adding a late fee clause to every invoice dramatically reduces late payments. Use this language:
"Invoices unpaid after [due date] are subject to a late fee of 1.5% per month (18% annually) on the outstanding balance."
Calculate the first month's late fee: if a $2,000 invoice goes unpaid, the late fee is $2,000 × 1.5% = $30. Small enough to not destroy the relationship, large enough to motivate payment.
Use the Late Fee Calculator to calculate the exact amount owed for any overdue invoice.
How to Get Invoices Paid Faster
- Send the invoice immediately. Waiting until end of month to invoice is a habit that costs you weeks of cash flow.
- State the due date explicitly. Write "Payment due: June 1, 2026" — not just "Net 30." Clients read the date, not the formula.
- Send a reminder the day before. A friendly "Just a heads up, this invoice is due tomorrow" email catches most late payments before they happen.
- Accept multiple payment methods. The harder it is to pay, the longer it takes. Accept ACH, card, and wire.
- Require a deposit on large projects. Ask for 25–50% upfront on any project over $2,000. This funds your work and filters out bad-faith clients.
