Late Payment Reminders for Overdue Invoices
Paste the invoice details. Get a reminder sequence from friendly nudge to final notice, each citing your terms, with subject lines ready to send.
River's late payment reminder writes the emails that get an overdue invoice paid. Paste the invoice number, amount, due date, how late it is and what you have sent so far. River writes the next reminder at the right level of firmness, plus the rest of the sequence: a friendly nudge, a firm follow-up, and a final notice that says what happens next. Each one quotes your invoice and your own payment terms, comes with a subject line, and is short enough to read on a phone.
Most late payment templates are one generic email with blanks for a name and an amount. They cannot tell how late the invoice is, whether you have already chased it, or what your contract allows, so the tone is too timid for the third reminder or too harsh for the first. This sequence escalates step by step. It uses only consequences you can actually carry out, such as pausing work or a late fee your contract sets, and brings in accounts payable when that is the faster route.
It is for freelancers, consultants and small studios chasing a client invoice, whether it is three days or three months overdue. Use it the day after the due date, not after weeks of awkward silence. The best protection comes earlier: a freelance contract that sets a due date, a deposit and what happens when payment is late gives every reminder something firm to point to, and keeps the conversation about agreed terms rather than feelings.
How to chase an overdue invoice without losing the client
Most late invoices are not refusals. They are stuck: sent to someone who left, waiting for a purchase order number, or sitting in a queue nobody owns. So the first reminder should make paying easy. Restate the invoice number, amount and due date, attach the invoice again, and ask whether anything is needed from you to process it. Send it to your contact and, if you know it, the accounts payable address. Many late payments are resolved at this step without any firmness at all.
If there is no answer, get specific. The second reminder says how many days overdue the invoice is, quotes the payment terms from your contract, and asks for a payment date rather than an apology. The third is the final notice. It states calmly what you will do and when, such as pausing work, applying the late fee your contract sets, or starting formal recovery. Include only steps you are willing to take. An empty threat teaches the client that your deadlines are negotiable.
The law can help in some places. In the UK, a business that pays another business late can owe statutory interest of 8% above the Bank of England base rate, unless your contract sets its own rate, plus a fixed recovery sum of £40 to £100. New York State's Freelance Isn't Free Act requires payment within 30 days of completion when a contract sets no date. Elsewhere, your contract usually decides what you can add.

Common questions
When should I send the first reminder?
The day after the due date, or even a few days before it as a courtesy note. Waiting weeks makes the invoice feel optional and the eventual reminder feel awkward. A first reminder that simply restates the details and reattaches the invoice is not pushy. Most clients read it as good organisation, and it often catches an invoice that went to the wrong person.
Can I add a late fee to an overdue invoice?
Usually only if your contract or invoice terms set one before the work started. River includes a late fee only when your terms do, and quotes them. In the UK, business clients can owe statutory interest and a fixed recovery sum even without a clause, unless the contract sets its own interest rate. Elsewhere, check local limits before charging interest.
Should I stop work until the client pays?
If your contract allows it and the invoice is well overdue, pausing work is often the most effective step you have, and it is easier to defend than a threat you cannot carry out. Say in writing when work will pause and what restarts it. River includes this in the final notice only if you tell it your terms allow it.
What if the client says they cannot pay right now?
Ask for a payment date in writing, or offer a short payment plan with fixed dates and amounts. A plan with a date is worth more than a promise to pay soon. Ask River in chat for a payment plan email that confirms the amounts and dates and what happens if one is missed. Then add those dates to your cash flow forecast.
When should I escalate beyond email?
When the final notice date passes without payment or a credible plan. Call your contact and, for a larger amount, the finance team. After that come a formal letter before action, a collection agency or small claims court, which differ by country. The demand letter template works out what is owed, interest included, and River can draft the letter. Get local advice before filing a claim.
