Late payments: the wording that gets an invoice settled
Chasing late payment as a small business: the four messages that work, word for word, what your terms let you charge, and when to send a demand letter.
Chasing late payment as a small business goes wrong for one reason: the emails get softer as the debt gets older. The first one is businesslike, the second apologizes, the third doesn’t get sent because it feels rude. Meanwhile the customer has learned that nothing happens if they ignore you. The wording that works is short, unemotional, identical every time, and attached to a date.
Send four messages on a fixed schedule: the day it goes overdue, day seven, day fourteen and day thirty. Never ask how they are, never apologize for chasing, always restate the number and the due date, and always include a way to pay in one tap. Below is the wording we use, and what your own terms let you add once politeness has run out.
Why chasing late payment as a small business goes wrong#
Three habits cause almost all of it. The first is variable wording, which signals that this is a negotiation. The second is going quiet between reminders, which reads as "not urgent". The third is chasing from your own emotions rather than from a calendar, so the customer who makes you nervous gets chased last, and that’s usually the one who owes the most.
Fix it by removing yourself from the decision. Put the dates in a calendar or let your invoicing send them. Our invoicing tool sends chasers automatically on the schedule you set, which means the day fourteen message goes out whether or not you feel like being the sort of person who sends it.
The four messages, in order, word for word#
Day one, the day after it was due. Subject line: Invoice 1042, due yesterday.
Hello Sarah, invoice 1042 for $2,400 was due on October 14 and I don’t think it has come through yet. The invoice is attached again and you can pay by card here: [link]. If it is already in hand, ignore this. Thanks, Iwan.
Day seven. Subject line: Invoice 1042, now 7 days overdue.
Hello Sarah, invoice 1042 for $2,400 is now seven days past its due date of October 14. Is there a problem with the work or with the paperwork? If there is, tell me and I will fix it today. If not, the pay link is here: [link]. Thanks, Iwan.
Day fourteen. This is where the tone changes. Subject line: Invoice 1042, 14 days overdue, service charge.
Hello Sarah, invoice 1042 for $2,400 is now fourteen days overdue. My terms carry a service charge of 1.5 percent a month on an overdue balance, which is $36 and starts from October 15. I would rather not add it. Please pay the $2,400 by November 5 using the link: [link]. Thanks, Iwan.
Day thirty. The demand letter, covered in its own section below.
The wording that works, and the wording that doesn’t#
| Don’t write | Write instead |
|---|---|
| Just a gentle nudge | Invoice 1042 is fourteen days overdue |
| Sorry to chase | Nothing. Delete the apology |
| When you get a chance | Please pay by November 5 |
| Hope you’re well | Straight to the invoice number |
| Let me know if there are any issues | Is there a problem with the work or the paperwork? |
| Our bank details are below | Pay by card here: [link] |
The one soft question worth keeping is "is there a problem with the work". It gives an embarrassed customer a face saving way to reply, and about a third of very late invoices turn out to be a quiet complaint nobody wanted to make.
What your terms let you charge#
Here’s the part that surprises people who have worked abroad. In the United States there’s no statute handing a private business interest on a late invoice. Nothing is owed on top of the invoice unless it was agreed in writing before the work started. Your terms are all the bargaining power you have, so they need three lines in them.
| Line in your terms | What it does | Where it goes |
|---|---|---|
| Service charge of 1.5% a month on overdue balances | Puts a meter on the debt and a number in the reminder | Estimate and invoice |
| Customer pays reasonable collection costs and attorney fees | Reverses the American rule, which otherwise leaves you paying your own lawyer even when you win | Estimate, signed |
| Payment due on a stated date, not in a stated number of days | Removes the argument about when the clock started | Every invoice |
Two limits worth knowing. Every state caps what you may charge on an overdue balance, tightly where the customer is a consumer and more loosely between businesses, and a rate above the cap can cost you the whole charge rather than the excess. And a term only binds if it was agreed, which means it belongs on the estimate the customer accepted. That’s the argument in estimates that win.
If you build, remodel or improve property, you have one more remedy that has no equivalent in ordinary trade: a mechanic’s lien against the property itself. It’s powerful, and it’s unforgiving about deadlines. Several states want a preliminary notice served within a few weeks of starting work, and every state sets a hard window after the last day on site for filing the lien itself. Look yours up now, while nobody owes you anything, because the deadline you miss is the one you read about after it has passed.
When to add the service charge#
Name it at day fourteen. Add it at day thirty. Naming it does most of the work, because the number stops being a favor and starts being a debt with a meter running. Adding it early to a customer who is just disorganized will cost you the relationship for the sake of about $36.
If you do add it, show the arithmetic on the invoice instead of in the email. On $2,400 at 1.5 percent a month, thirty days is $36 and ninety days is $108. Small money. Serious signal. And keep it consistent: a charge you apply to one customer and waive for the next is a charge a court will treat as decoration.
The demand letter#
- Head it "Demand for payment" and date it.
- State the invoice number, the amount, the date of the work and the due date.
- List the reminders you sent, with their dates. This matters if a judge ever reads it.
- Give the total now claimed: invoice, service charge to date, anything your terms allow.
- Give a deadline. Fourteen days for a business, thirty days for an individual.
- Say clearly that you’ll file in small claims court without further notice if it isn’t paid.
- Send it by email and by certified mail with a return receipt, and keep both.
Two cautions. Don’t threaten anything you aren’t prepared to do, because an empty threat trains the customer. And if you hand the debt to a collection agency instead of chasing it yourself, federal debt collection rules start applying to them and, indirectly, to how you are seen; pick one that can tell you which rules it follows.
A worked example: $4,200 over ninety days#
A store fixture installer invoiced a coffee chain $4,200 on June 2 with fourteen day terms, due June 16. Reminders went out on June 17, June 23 and June 30 with no reply. On July 16 he sent a demand letter giving fourteen days, claiming $4,200 plus a service charge of $63 for the month, so $4,263.
Payment of $4,263 arrived on July 24, eight days after the letter and thirty eight days after the due date. No court, no attorney, about forty minutes of his time in total. The finance manager’s reply said the invoice had been sitting waiting for a purchase order number that nobody had asked him for, which is the most common reason of all.
Had it gone further, $4,200 sits inside the small claims ceiling in most states, the filing fee is typically under a hundred dollars, and you can appear without a lawyer. Check your own county’s limit and fee before you count on it, because both are revised.
What to do before the next one goes late#
- Put the terms on the quote as well as the invoice, and get the quote accepted in writing.
- Ask commercial customers for a purchase order number before you start.
- Write the actual due date on the invoice, not "14 days".
- Take a deposit on anything over a few hundred dollars.
- Put a card link on every invoice so paying takes one tap.
- Send a one line reminder two working days before the due date, which prevents more late payments than all four chasers combined.
Most of that is the same short list as getting paid faster, best done in the order given. If late payments are already affecting what you can order next month, put the dates on a single page and look at them weekly, which is the method in cash flow forecasting on one page.
Questions people ask about this
How much interest can I charge on a late invoice?
Whatever your written terms say, and nothing at all if they say nothing. There’s no federal statute handing a private business interest on an overdue invoice the way some countries do, so the number has to be agreed before the work starts. The usual figure in American trade is 1.5 percent a month, which is 18 percent a year. States cap what you may charge, tightly for consumers and more loosely between businesses, so check your own before you print it on anything.
Can I recover what it costs me to chase the money?
Only if your contract says so. Under the American rule each side pays its own attorney whatever the outcome, so a single sentence putting reasonable collection costs and attorney fees on a defaulting customer is the most valuable line in a small contract. Add it to the estimate, not the invoice, because it has to be agreed before the work starts.
When should I send a demand letter?
Once the ordinary reminders have run out, usually around thirty days past due. Give a business fourteen days to respond and an individual thirty. Send it by email and by certified mail with a return receipt, because the receipt is the part a judge can see, and keep a copy of everything you sent before it.
What payment terms apply if I never agreed any?
Payment is due within a reasonable time, and what a court thinks is reasonable is decided after the argument rather than before it. The debt is still owed, but you have no late fee, no interest and no costs clause, because none of those were agreed. That’s why terms belong on the estimate: so the customer knows the clock exists.
Is it worth taking a small debt to court?
Below about $600 it usually isn’t, once you count the filing fee and your own time. Above that it often is. Small claims needs no attorney, the ceiling is somewhere between $5,000 and $15,000 depending on your state, the filing fee is normally under a hundred dollars and the winner usually recovers it. The bigger question is whether the customer has any money, because a judgment against an empty company is a piece of paper.
