Past Due Invoice Letter Template: Reminder, Second Notice, Final Notice

What this builds

Three letters about one invoice, in the order you send them. A friendly reminder that assumes the bill was simply missed. A second notice that says how far past due the balance is and, if your own terms provide for one, carries the late fee. A final notice that names a date and says the account may be referred to a collection agency. Pick a stage, fill the fields once, and print, save a PDF or copy the letter as text. There is no signup and no email wall, and the draft saves in your browser rather than on a server.

The fields do not reset when you change stage. Fill the reminder, send it, and if the money has not arrived in a fortnight, switch to the second notice: the invoice number, the amount and the customer name are still there, and the letter rewrites itself around them.

Stage one: assume it was missed

Most unpaid invoices are not a refusal to pay. They are an invoice that landed in a spam folder, went to the wrong person at a property management company, or arrived the week a customer was away. The first letter is written for that reader: it names the invoice and the due date, repeats how to pay, invites a correction if something on the bill is wrong, and thanks them. No fee, no deadline, no consequence.

Sending it early matters more than the wording. The whole how to get paid faster sequence works on the same principle: every day between finishing the work and asking for the money is a day the balance ages, and an aged balance is harder to collect.

Stage two: state the facts and your own terms

The second notice is where the letter stops being a nudge. It states how many days past due the balance is, recites the date you wrote before, and asks for payment by a date. If your agreement or your invoice provides for a late fee, the fee paragraph says so in your own words and prints the balance you type.

That paragraph deliberately states no rate. What you can charge comes from what your customer agreed to and from the law where you work, and a number printed by a template is neither. Work the figure out on the invoice late fee calculator, which applies your own rate and grace period to the days the invoice has been outstanding, then put the wording and the new balance into the letter. If you have no late-fee term, untick the section: a fee you never agreed is a fee you will end up waiving in the argument that follows.

Two habits make the second notice land. Attach the invoice again rather than assuming it is on the customer’s desk: the service invoice template and the invoice generator both reprint a clean copy with the same numbers. And keep a note of the date you sent each letter, because the next stage recites them.

Stage three: one consequence, and a way out

The final notice is the last letter you send before the account leaves your hands. It names the prior notices, sets a date, and says the account may be referred to a collection agency if the balance is not paid or an arrangement agreed by then.

That is the only consequence this template will print. Court, a lawsuit, credit reporting, interest and costs, attorney fees: those are legal claims, and they belong to an attorney licensed where you work rather than to a page like this one. An unenforced threat is also worse than no threat, because it teaches a customer that nothing in your letters is real. What the stage keeps, alongside the deadline, is the offer to agree a payment arrangement. Most balances that look like refusals are cash-flow problems, and an arrangement collects more money than a referral does.

Stop the next one before it starts

Chasing is the expensive half of getting paid, and most of the causes sit upstream of the letter. Invoice at completion, take a deposit on large jobs, put recurring accounts on card-on-file, and write net terms and a late fee into the agreement you already ask customers to sign. If a customer is consistently slow and consistently priced below what the work costs you now, the price increase letter template is the other letter in this set: same fill-and-print mechanics, aimed at the rate rather than the balance.

Everything runs in your browser. No account, no email gate, and nothing typed here is uploaded. A starting-point template only, not legal advice: late fees, notice requirements and collection practice vary by jurisdiction, so have a licensed attorney where you work review anything you intend to rely on for a contested balance.
