Summary
Waive a late fee by applying it automatically the day an invoice goes overdue, then cancelling it with a credit note once the customer pays the original inside a stated window. The fee sets the deadline. The waive is a decision a named person makes on a rule, and it protects the relationship.
- When to waive: Waive when the payment lands, not when the customer objects, because waiving on objection teaches every customer to object.
- How to reverse it: Credit note the separate fee invoice rather than editing or deleting the original invoice, so the charge and the concession both stay on the ledger.
- Paidnice: Paidnice applies the fee on every overdue invoice in a group, lets a named user waive or credit it inside the app, and reports late fees charged against late fees collected.
This guide is for the person who owns the debtors list and wants a late fee that customers take seriously, without losing the customers worth keeping.
What is a late fee (and what is it not)?
A late fee is a charge a seller adds to an invoice when the customer pays after the due date, as a flat amount, a percentage or interest. It is also called a late payment fee. See the definition of a late fee.
- Waiving a late fee is not a write-off. A write-off removes an unpaid invoice from the receivables. A waiver removes only the fee. The original invoice is still owed. NetSuite users can see how to waive or reverse a finance charge.
- A late fee is not an early payment discount. A cash discount cuts the price for paying early. A late fee is added after the due date, and a waiver takes it off again.
- A late fee is not due inside a grace period. The grace period is the days after the due date before the fee starts. Nothing is waived if nothing was charged.
This matters because a waiver is a decision about one charge you chose to add. Keep it separate from the invoice, so the credit note shows exactly what you conceded.

A late fee you intend to waive still moves your invoice up the customer's payment run, because it is the one invoice in their queue that costs money to ignore. The waive is a separate decision, made later by a named person against a rule.
An overdue invoice competes for attention inside your customer's accounts payable process against every other invoice they owe. Nothing else distinguishes yours from the other four hundred in the queue. The charge is what turns it into the one an accounts payable clerk raises with their manager.
The fee is leverage, so it has to be real, visible, and growing. Offering to remove it in exchange for immediate payment hands the customer a reason to move this week rather than next, without anyone having a difficult conversation. Whether the fee is collected or waived at the end is a decision the account owner makes, on the rule set out below.
The businesses that collect the most late fee revenue are almost never the ones with the highest rates. They are the ones that apply the fee to every overdue invoice without exception, then waive deliberately. Consistency is what makes the charge credible. A fee that appears on some invoices and not others is read, correctly, as negotiable.
Waiving is normal. About 1 in 4 late fees is waived, and about 6 in 10 are paid in full.
When should you waive a late fee?
Waive a late fee when the customer's payment of the original invoice clears inside the stated window, never when the customer objects to the charge. The trigger is money arriving, so the fee is removed by a rule rather than by whoever is most persistent.
Objection-triggered waiving is what most businesses do by default because it feels like good service. Somebody rings up annoyed, you do not want the argument, you remove the charge. It is the most expensive habit in credit control I see. You have just taught that customer, and anyone they talk to, that the fee disappears if you complain about it. The next overdue invoice produces a complaint instead of a payment.
If they pay outside the window, the account owner has a decision to make rather than a rule to follow. Most businesses still waive the first time and say so explicitly, which keeps the deadline meaningful for next time. The data on late fees and on-time payment shows why: a fee that is applied by default and waived on purpose still lifts payment.
Should you void or credit note a waived late fee?
Credit note a waived late fee. A void makes the fee vanish as though it was never charged, and a credit note keeps the charge, the concession and the date on the ledger, which is the record you want the next time the customer is late. Both options exist because the fee was raised as its own invoice.
| Action | Use when | What it leaves behind |
|---|---|---|
| Void | The fee invoice was never sent, or was sent in error | The invoice number is retained but the transaction disappears from reports. Cleanest for a fee that should not have existed. Not available once the period is locked or the year is closed. |
| Credit note | The customer received the fee and you are choosing to remove it | Both documents stay on the ledger. The charge, the concession, and the date are all visible. |
The credit note is the proof that you charged, and then chose not to collect. It is what your accountant expects to see at year end. Full detail on the tax and account treatment is in how to account for late fees.
The fee does not have to be posted yet. If you do not want charges landing in the ledger before a human has looked at them, raise the fee as a draft invoice. It is calculated and attached to the right customer, and nothing has been sent. Approve the ones you want to go out and delete the rest, then switch to automatic approval once you trust the policy.
What you should not do is keep the fee outside the ledger entirely. A charge that only exists inside a reporting tool never reaches the customer's payables system, so it never enters their approval queue or their payment run. It also cannot be reconciled when paid, has no tax treatment, and is not evidence if you escalate. There is more on that in invoice late fee or statement interest.
Why is a waived fee a record worth keeping?
A waived late fee is a documented concession that earns its keep three times: in the next payment terms conversation, at year end, and in a dispute.
- In the next conversation. "We waived £340 in interest across your last four invoices" is a specific, checkable statement. It changes a payment terms discussion more than any general complaint about slow payment.
- At year end. Your accountant can see charges raised and charges credited, rather than a gap where a policy should be.
- In a dispute. A consistent record of applying and waiving shows the fee is a policy, not a retaliation. That matters if the charge is ever tested, particularly outside the UK and EU where the right to charge is contractual.
When should you not waive a late fee?
Three situations where a late fee should not be waived: repeat offenders who have already had two concessions, accounts already heading for formal recovery, and invoices in genuine dispute, which should never have carried a fee at all.
Repeat offenders. If a customer has had a fee waived twice already, a third waive is not goodwill, it is a discount they have learned to expect. Charge it and say why.
Accounts heading for escalation. Once you are drafting a letter before action, accrued interest is part of the claim. Waiving it weakens what you are about to send.
Anything genuinely disputed. This one is different: a disputed invoice should never have received a fee in the first place. Pause the account, resolve the dispute, then resume. Applying a charge to an invoice the customer has legitimately queried hands them a reason to stop discussing the debt and start discussing your conduct.
If the customer genuinely cannot pay rather than will not, a payment plan is the better instrument than either charging or waiving.
What should the waive email say?
The waive email names the invoice, states the charge already applied and how it was calculated, gives the date by which paying the original cancels it, and invites the customer to raise any problem. A second email confirms the waive and restates the rule.
Subject: Invoice INV-2418, and how to avoid the late payment charge
Hi [Name],
Invoice INV-2418 for £3,400 was due on 14 July and is now 21 days overdue. In line with our payment terms, late payment interest of £22.98, charged at 11.75% a year, and a fixed recovery charge of £70 have been applied. We have raised these as invoice INV-2419.
If the original £3,400 reaches us by Friday 14 August, we will cancel that charge in full. We would much rather close this out than collect it.
If something is holding the invoice up, tell me what it is and I will sort it.
Subject: Payment received, charge canceled
Hi [Name],
Thanks, the £3,400 landed this morning. As promised, I have canceled the late payment charge of £92.98 and credited invoice INV-2419 in full, so there is nothing further to pay.
For future invoices the same terms apply: the charge is raised when an invoice passes its due date, and canceled if it is settled within ten days.
The second message matters more than it looks. It restates the rule at the moment the customer is feeling good about you, which is exactly when a payment terms reminder lands best. More templates are in our guide to telling a customer you are charging a late fee.
Does where you invoice change how you waive?
In the UK and the EU the right to charge is statutory and automatic, so waiving a late fee is purely a commercial choice. Almost everywhere else the right is contractual, established by your payment terms, and waiving inconsistently there is a risk rather than a habit.
If you charge some customers and not others with no stated rule, a customer in a contractual market can argue you waived the term on their account, which is narrower but still an argument you do not want. Write the policy down, apply it the same way, and record the exceptions.
Outside the UK and EU, an unwritten late fee is usually an unenforceable one. The clause has to exist before the invoice does. See our late fee policy wording examples and payment terms templates. Country-by-country detail is in how much can I charge for late fees, and the limit in each US state is in US late fee laws by state.
How Paidnice does this, and how simple it is
Paidnice applies the late fee on every overdue invoice in a customer group, so the charging half of apply-then-waive runs without anyone deciding to charge anyone. The waive stays a human decision: a named user waives or credits the fee inside the app, one invoice at a time or in bulk.
- The fee applies itself on every overdue invoice in the group, so nobody has to decide to charge anyone on a Monday morning.
- Choose draft or approved. Draft holds the charge for review before it reaches your ledger. Approved posts it straight away once you trust the policy.
- Waiving is one action. A user waives or credits the fee inside Paidnice, in bulk where a whole account has settled, and the credit lands on the separate fee invoice in Xero or QuickBooks, so the original invoice is untouched.
- Credit on the account is handled for you. If the customer has unallocated credit notes, the charge is calculated on the net balance rather than the gross, so you never charge interest on money they have already been credited.
- The report shows the decisions. Paidnice reports late fees charged against late fees collected, so you can see how often the fee did its job as leverage and how often it was collected.
Setting it up is one policy on one customer group, and most people start in draft for the first month.
Common questions
What does it mean to waive a late fee?
Waiving a late fee means cancelling a charge that was validly applied, as a deliberate concession, usually because the customer paid the original invoice inside an agreed window. The fee was real. The waive is the record that you chose not to collect it.
Should I tell the customer the fee might be waived?
Yes, in the same message that applies it. A fee with a stated way out reads as a process. A fee with no way out reads as a punishment, and gets treated like one.
Does waiving a fee weaken my position later?
Not if it is recorded and consistent. What weakens your position is waiving silently, because then there is no evidence the charge was ever a real term.
Can I waive part of a fee?
Yes, with a partial credit note. It is common on a large balance where you want to acknowledge a genuine delay on your side without dropping the charge entirely.
What if they pay the original but not the fee?
That is the normal outcome, and usually the one you wanted. Waive it, confirm it in writing, and restate the terms.
Do I have to charge VAT on a fee I am about to waive?
UK statutory interest and compensation are outside the scope of VAT, so the charge should carry no tax at all rather than a zero rate. How to account for late fees covers the detail and the other markets.
What do I do when a customer writes asking for a late fee to be waived?
Reply with the rule, not a judgement call: the charge is cancelled when the original invoice is paid by the stated date. If the money has already landed inside the window, confirm the waive in writing. If it has not, the request is a reason to chase the payment, not to drop the fee.
