Payment terms, late fees, and follow-up etiquette

Monkee · September 15, 2026

Payment terms are the rules of the money game, and most freelancers never write them down. Then they wonder why every invoice becomes a negotiation. Terms stated upfront do three things: they set expectations before money is on the table, they give your follow-ups standing, and they make late fees enforceable instead of awkward. This guide covers choosing terms, writing late fee policies that work, and the exact follow-up sequence to run when a client misses the date.

Net-14 vs net-30: choosing your terms

"Net-14" means payment is due 14 days after the invoice date; "net-30" means 30 days. Both are standard. Which to use:

• Net-14 is the freelancer default and the right one for most project work. Your cash flow is your payroll; waiting a month to be paid for finished work is a loan you never agreed to give.
• Net-30 is what larger companies expect, because their accounts payable runs on monthly cycles. If you invoice enterprises regularly, net-30 matches their machinery and reduces "we pay on 30-day terms" pushback.
• Net-7 or due on receipt works for small amounts and rush jobs. State it plainly; small invoices paid fast beat small invoices forgotten. There is more on where "due upon receipt" helps and where it backfires in its own guide.

For the full breakdown of what each net term means and how to match it to your clients, see net 30, net 15, net 60: what they mean and which to choose.

Whatever you choose, put it in writing twice: once in your proposal or contract, once on the invoice itself. Terms the client sees for the first time on the invoice are terms you will have to defend. Terms agreed before the work starts are just the deal.

Payment terms: net-14. Invoices are due within 14 days of
the invoice date. Please reference the invoice number with
your payment. A late fee of 1.5% per month applies to
balances unpaid more than 7 days after the due date.

Late fees that work (without souring the relationship)

Late fees are not really about the money. A 1.5% monthly fee on a $3,000 invoice is $45: nobody is getting rich. Their real job is psychological. A stated late fee turns "pay whenever" into "pay by this date or it costs more," and it gives your follow-up emails a factual anchor instead of a pleading tone. We go deeper, including the case for early-payment discounts, in late fees and early-payment discounts.

What makes a late fee policy work:

• State it before the work, not after the delay. A fee announced in the follow-up email is a threat. The same fee in the proposal is a policy.
• Keep it modest and simple. 1 to 1.5% per month is the common range freelancers use. Flat fees ($25 or $50 per late invoice) are simpler to explain and easier to actually apply.
• Include a grace period. Seven days past the due date before the fee kicks in. It costs you almost nothing, it reads as fair, and it removes the client's best objection ("it was only two days late").
• Apply it rarely, mention it always. Most clients pay on time once the policy exists. The fee's value is in the stating, not the collecting. When you do apply one, do it matter-of-factly, like an airline applying a baggage fee.
• Check your local rules. Some jurisdictions cap late fees or require specific wording. A quick check of your local rules beats an unenforceable clause.

Late payments: balances unpaid more than 7 days after the
due date accrue a late fee of 1.5% of the outstanding
balance per month, or $25, whichever is greater. If you
anticipate a delay, please contact me before the due date
and we will work something out.

That last sentence matters more than the fee. It tells good clients having a bad month that they can talk to you, which is exactly what separates a policy from a punishment.

The 3-email follow-up sequence

Follow up on a schedule, not on frustration. Three emails, each short, each factual, each with the invoice number, the amount, and a fresh copy of the invoice attached. No guilt, no essays.

Email 1: the due date (friendly nudge)

Send on the due date itself. Assume it got buried, because usually it did.

Subject: Quick check on invoice [INV-NUMBER]

Hi [NAME],

Just checking on invoice [INV-NUMBER] for [AMOUNT], due
today. Copy attached in case it got buried.

Thanks,
[YOUR NAME]

Email 2: seven days late (firm, still warm)

One week past due. Reference the terms they agreed to, and name a specific next step.

Subject: Invoice [INV-NUMBER] now 7 days overdue

Hi [NAME],

Invoice [INV-NUMBER] for [AMOUNT] was due on [DUE DATE]
and is now a week overdue. Per our agreed terms, the late
fee policy applies from [FEE START DATE].

Could you let me know when I can expect payment? Copy
attached.

Thanks,
[YOUR NAME]

Email 3: fourteen days late (final written notice)

Two weeks past due. Short, direct, and with a phone number. This is the last email before you call.

Subject: Final notice: invoice [INV-NUMBER], [AMOUNT]

Hi [NAME],

Invoice [INV-NUMBER] for [AMOUNT], due [DUE DATE], is now
14 days overdue. I need payment arranged this week.

If there is a problem with the invoice itself, tell me and
I will fix it today. Otherwise please confirm a payment
date. You can reach me directly at [PHONE].

Follow-up etiquette: the rules that keep it professional

• Short and factual. Invoice number, amount, due date, attached copy. Every extra paragraph weakens the email.
• One thread. Keep all follow-ups in the same email thread so the history is visible to everyone, including the client's boss if it gets forwarded.
• Attach a fresh copy every time. "In case it got buried" is usually true, and it removes the client's easiest excuse.
• Send to the billing contact, CC your day-to-day contact. The person who hired you often cannot release money. The billing contact can, and the CC keeps your contact in the loop without making them the messenger.
• Escalate the channel, not the tone. Email, then email, then phone. A calm phone call after two emails resolves more invoices than a furious third email ever will.
• Pause future work, politely. After the second follow-up, it is fair to say new work waits until the balance is current. This is the single most effective lever freelancers have, and it is completely reasonable.

When to stop chasing and adjust instead

Sometimes the invoice is fine and the client simply cannot pay right now. If a good client tells you that honestly, consider a payment plan in writing (amounts and dates, both signed) rather than an indefinite wait. And if you ever reduce what is owed to close things out, document it properly with a credit note so your records stay clean.

Nobody pays faster because you asked nicely. They pay faster because the terms were clear before the work started, and the follow-up arrives like clockwork.
