Short answer: For most freelancers, Net 15 is the sweet spot — short enough to protect your cash flow, standard enough that clients won’t push back. Reserve Due on Receipt for new clients without an established payment history, and only accept Net 30+ from larger, reliable clients where the relationship justifies the wait.

What each common term actually means

Term	Meaning	Best for
Due on Receipt	Payment expected immediately upon receiving the invoice	New clients, small one-off projects
Net 15	Payment due within 15 days of the invoice date	Most freelance work — a good default
Net 30	Payment due within 30 days of the invoice date	Larger companies with standard AP cycles, established clients
Net 60 / Net 90	Payment due within 60 or 90 days	Rare, usually only accepted from very large, reliable clients — avoid if possible
50% upfront / 50% on delivery	Half paid before work starts, half on completion	Larger projects, new client relationships, reducing your risk

Which terms should you actually use

💡

The freelancer’s dilemma: shorter terms protect your cash flow, but some clients (especially larger companies) have accounts-payable processes that default to Net 30 or longer, regardless of what you request. The practical approach: state Net 15 as your default on every invoice, but be prepared to accept Net 30 from established companies where the relationship and reliability justify it — and use upfront deposits to manage risk on new or large engagements instead of fighting over the term length.

How to word it on your invoice

State the term explicitly and unambiguously, both as a label and a specific date — don’t rely on the client to calculate it themselves.

📝

Good: “Payment terms: Net 15 — Due by July 30, 2026”
Weak: “Payment terms: Net 15” (with no specific date shown)

Showing the actual due date removes any ambiguity or excuse about miscounting days, and makes it easier for a client’s accounts-payable system to schedule the payment correctly.

Late payment penalties — and whether to use them

Adding a late fee clause (commonly 1.5-2% per month on the overdue balance) is standard practice and legally enforceable in most US states when stated clearly in your contract or invoice terms beforehand. In practice, most freelancers rarely collect the fee itself — its real value is as a deterrent and a negotiating chip (“I can waive the late fee if we settle this today”).

Approach	Pros	Cons
Include a late fee clause	Deterrent effect, negotiating leverage, industry-standard	Rarely worth pursuing collection for small amounts
No late fee, firm follow-up instead	Simpler, less adversarial framing	Less leverage if a client is genuinely slow-paying

Negotiating terms with a client who wants Net 60+

If a client’s standard process is Net 60 or longer and it’s non-negotiable, the practical fix isn’t fighting the term — it’s adjusting the deal around it: request a larger upfront deposit (40-50% instead of the usual amount) to reduce how much of your cash is tied up waiting, or factor the extended wait into your rate for that client. Some freelancers also use invoice factoring services for large, slow-paying clients specifically, trading a small fee for immediate cash.

Frequently asked questions

Can I legally charge a late fee without a signed contract? +

Late fees are generally only enforceable if the client agreed to the term beforehand — stated on the invoice alone, after the fact, usually isn’t sufficient. Include payment terms and any late fee clause in your contract or proposal before work begins, and repeat the terms on every invoice for clarity.

Should I offer a discount for early payment? +

Some freelancers offer a small discount (e.g., 2% off if paid within 10 days instead of the standard 15 or 30) to incentivize faster payment, especially with larger invoices. It’s optional and works best as a clearly stated line item (“2/10 Net 30” is common shorthand) rather than an informal offer.

What do I do if an invoice is already overdue? +

Send a polite, direct follow-up as soon as it’s overdue rather than waiting — most late payments are oversights, not refusals. See our guide on handling late-paying clients for a full escalation script.

Do payment terms need to be the same for every client? +

No — it’s common and reasonable to vary terms by client size, project size, and how established the relationship is. A new client on a small project might get Due on Receipt or 50% upfront, while a long-standing client on a large retainer might reasonably get Net 30. Just be consistent with each individual client once terms are set, to avoid confusion.
