The single biggest upstream lever for getting paid on time isn't your reminder sequence — it's the wording in your payment terms field. Most freelancers write “Net 30” out of habit, without knowing there are better options, or leave the field blank entirely.
Payment terms wording is the language on your invoice and in your contract that specifies exactly when payment is due, what discount a client gets for paying early, and what penalty applies if they don't. Getting that wording right is the cheapest thing you can do to shorten the gap between delivery and deposit — before any reminder ever needs to go out.
The five most common payment terms (with copy-pasteable wording)
These cover the vast majority of freelance and small-agency work. Pick the one that fits your situation and paste it directly into your invoice terms field and contract.
Due on Receipt
Payment is due the moment the client receives the invoice. This is the most aggressive timeline and works best for one-off projects, rush work, or clients who have a history of dragging payments out.
Payment terms: Payment is due upon receipt of this invoice. Please process payment within 24 hours of receipt.
One honest caveat: “due on receipt” sounds clear but is surprisingly easy for clients to reinterpret as “whenever I get around to it.” Pairing it with a specific fallback — “and no later than [date]” — removes that wiggle room.
Net 15
Payment is due 15 calendar days from the invoice date. This is the sweet spot for most freelance work: it gives a client enough time to route the invoice through their internal process, while keeping your cash-flow window reasonably tight.
Payment terms: Net 15. Payment is due by [specific date — 15 days from invoice date]. Please refer to the invoice date above.
Research suggests Net 15 invoices tend to be paid 8–10 days faster on average than Net 30 invoices — a meaningful difference if you're managing cash flow month to month.
Net 30
Payment is due 30 calendar days from the invoice date. This is the default in many industries, which is partly why it persists — and partly why so many Net 30 invoices get bumped to day 40 or 45 without a second thought.
Payment terms: Net 30. Payment is due in full by [specific date — 30 days from invoice date].
If you use Net 30, always include the explicit calendar date alongside the net-term notation. Invoices with a specific due date printed on them get paid faster than those with only “Net 30” — clients don't always do the math themselves, and an ambiguous due date is a free gift to the procrastinators.
2/10 Net 30 (Early Payment Discount)
This structure offers the client a small discount — typically 2% — if they pay within 10 days, with the full amount due in 30 days if they don't. It's an elegant way to make early payment feel like a reward rather than a demand.
Payment terms: 2/10 Net 30. A 2% discount applies if payment is received within 10 days of the invoice date. Full amount is due by [date — 30 days from invoice date].
To decode the shorthand: the first number is the discount percentage, the second number is the discount window in days, and “Net 30” is the standard due date. You can adapt it — “1/7 Net 15” offers 1% off for payment within 7 days on a Net 15 invoice.
Milestone / Instalment
For longer projects, splitting payment into stages protects both sides and removes the end-of-project cash squeeze.
Payment terms: This project is invoiced in two instalments. 50% deposit due upon project start; remaining 50% due within 7 days of final delivery. Each instalment is subject to the late fee terms below.
Be explicit about what “delivery” means to avoid disputes — link it to a specific deliverable or approval step, not a vague “when work is complete.”
How to word your late fee clause
A late fee is far easier to enforce when it was disclosed before the work started — and in many jurisdictions, disclosing it up front is what makes it stick at all (the exact rules vary by country, state, and contract). The same line belongs in your contract and on the invoice itself — stated plainly, not hidden in the footer in 6pt type.
Late payment: Invoices unpaid after the due date are subject to a late fee of 1.5% per month (18% per annum) on the outstanding balance, accruing until paid in full.
Keep the tone matter-of-fact. This is a policy, not a threat. Clients see this kind of language from their utility providers and software vendors all the time — it signals that you run a business with standard terms, not that you're anticipating a fight.

Where to put payment terms — invoice footer, contract, or both
Both. Always both. Here's why each location serves a different purpose:
- Your contract or engagement letter is where payment terms are agreed to before any work begins. This is the document that makes them enforceable. If it's not in the contract, a client can claim they never agreed to your terms.
- The invoice itself is where terms are reminded at the moment the money is actually owed. A clean invoice footer with due date, late fee clause, and payment instructions does most of the work so your reminder emails don't have to.
A common mistake is to put terms in the contract and then issue invoices that just say “Net 30” with no further detail. That technically works — the contract governs — but it creates more friction and more calls to “clarify” what's owed. Repeating the key terms on the invoice removes that friction. When the invoice does eventually need a nudge, our invoice reminder email templates already reference the terms you set here, so the follow-up points straight back to the due date the client agreed to.
Rule of thumb: your invoice footer should answer three questions without the client having to look anywhere else — when is this due, how do I pay, and what happens if I'm late?
What if you don't state any payment terms at all?
Leaving the terms field blank doesn't mean payment is due “whenever” — it means you've handed the timeline to a default you didn't choose. In many jurisdictions, if no terms are agreed, invoices fall back to a statutory default (commonly 30 days from receipt) and any right to charge interest or a late fee becomes far harder to enforce, because you never disclosed one up front.
In practice, a blank terms field does two things, both bad: it invites the client to set their own pace, and it strips you of leverage the moment things go quiet. Stating terms explicitly — even the most generous ones — always beats staying silent.
Net 15 vs Net 30 — which should freelancers default to?
If you've been defaulting to Net 30 because it's industry standard, it's worth asking: standard for whom? Net 30 became the norm in industries where accounts-payable departments need time to route invoices through an approval chain. If your client is a solo founder or a small marketing team, that logic doesn't apply — there's no AP queue to worry about.
Default to Net 15 if:
- You work primarily with small businesses, startups, or individual clients.
- Your invoices are for completed work rather than ongoing retainers.
- Cash flow is tight and a two-week difference in payment timing matters to you.
Stick with Net 30 if:
- You regularly work with enterprise clients or large organizations where 30-day cycles are built into their systems.
- You invoice on retainer and have a predictable monthly income rhythm regardless.
- Relationship-building is a higher priority than tightening the payment window.
The honest answer for most freelancers: start at Net 15 and only extend to Net 30 when a specific client genuinely needs it. You can always negotiate up; it's harder to negotiate down once a client is used to 30 days.

Clear terms reduce the chase — but they don't eliminate it
Getting your payment terms wording right is the best upstream move you can make. It sets expectations, reduces disputes, and gives your reminders something concrete to point back to.
But even perfectly worded terms don't guarantee every client pays on time. When an invoice does go quiet, reminding clients to pay — or following up on an unpaid invoice — still takes time and mental energy. That's the part automated invoice reminders handle: watching every open invoice, sending the right message at the right moment, and stopping the second a payment lands.

Frequently asked questions
What does Net 30 mean on an invoice? Net 30 means the full balance is due 30 calendar days from the invoice date — so an invoice dated March 1 is due by March 31. “Net” refers to the full amount owed, and the number is the count of days you're giving the client to pay. Net 15 and Net 7 work the same way with shorter windows.
Can freelancers use Net 15 instead of Net 30? Yes. Payment terms are yours to set — nothing requires Net 30. As long as the term is agreed before the work starts and stated on the invoice, Net 15 (or Due on Receipt) is just as valid, and it typically gets you paid sooner. A common approach is to start new clients at Net 15 and only extend to Net 30 once they've proven reliable.
Is “due on receipt” the same as due immediately? In practice, “due on receipt” usually means payment is expected by the end of the next business day rather than the literal instant the invoice arrives. Because that leaves room for interpretation, it helps to pair it with a specific fallback date — “due upon receipt, and no later than [date].”
Should payment terms go on the invoice or in the contract? Both. The contract is where the terms are agreed and made enforceable before work begins; the invoice is where they're restated at the moment payment is owed. Putting them in only one place is the most common source of “I didn't know that was the deadline” disputes.
