How to chase unpaid invoices politely
To chase unpaid invoices politely, confirm the invoice is really unpaid, send a friendly reminder a few days after the due date, and follow up with a firmer but courteous note if there is no reply. Always name the invoice, the amount and an easy way to pay. Move to a phone call before anything formal.
- Check your records first, so you never chase an invoice that was already paid.
- Send a short, friendly reminder a few days after the due date, with the invoice attached.
- Escalate in small steps: a second note, then a phone call, then a formal letter.
- Keep every message factual, name the amount and due date, and make paying easy.
- Late fees, interest and collections rules vary by location, so check with a qualified advisor before using them.
Step by step
Confirm the invoice is really unpaid
Before you write anything, check your bank and your books. Payments often arrive under a different name, as one lump for several invoices, or a day or two late. Also check the invoice itself: was it sent to the right person, with the right amount and a purchase order number if the customer needs one? An overdue invoice may be stuck in the customer’s approval queue, not ignored. A reminder about money you already received is the fastest way to annoy a good customer.
Send a friendly nudge just after the due date
A few days after the due date, send a short note that assumes a simple oversight. Name the invoice number, the amount and the original due date, attach a copy and say how to pay. Keep the tone light: “in case this slipped through”. Send it to the person who pays the bills, not only your day-to-day contact. Many late invoices are simple oversights, so there is no need to sound stern.
Follow up with a clear second reminder
If a week or so passes with no reply, send a second note. It is still polite, but more direct: say the invoice is now overdue, restate the amount, and ask for a payment date. Asking for a date matters, because it turns a vague promise into something you can check. If the customer has a problem with the work, ask them to say so now, so you can fix the dispute rather than the payment.
Pick up the phone
When two written reminders go unanswered, call. A short, calm call is hard to ignore and often finds the real reason: a missing purchase order, a staff change, cash flow trouble. Ask what you can do to help it get paid, and agree a date and a method while you are talking. Follow the call with a two-line email that records what was agreed. That email is your paper trail.
Offer options if the customer is struggling
If the customer says they cannot pay in full, a short payment plan is often better than a standoff. Agree the amounts and dates in writing, and pause new work or credit until the plan is on track. Check with an accountant or adviser before waiving any part of the debt, because it can affect your books and taxes.
Escalate in writing, and know when to stop
If the customer goes quiet after the call, send a formal final notice that states the amount, the due date, the date you will take the next step and what that step is. Collections, interest, late fees and court claims follow different rules in each country and state, and sometimes by customer type. Before taking any such step, speak with a qualified advisor or lawyer in your area. Do not threaten anything you are not prepared or permitted to do.
How can you make invoices easier to pay in the first place?
The best way to chase less is to prevent late payment. Invoice as soon as the work is done, put the due date and payment method at the top, and send it to the person who approves payment. For larger jobs, agree terms in writing before you start.
- State payment terms on every quote and invoice.
- Add a link or bank details so paying takes one step.
- Ask new customers who will approve the invoice and whether they need a purchase order.
- Keep a simple list of overdue invoices and review it at the same time each week.
When should you not chase by email?
If a customer has a genuine dispute, a bereavement or an obvious crisis, automated or routine reminders can do harm. Pause them and speak to the person. A relationship that lasts is usually worth more than a few weeks of earlier cash.
Reminder wording to adapt
- Friendly nudge: Hi [name], a quick note in case this slipped through: invoice [number] for [amount] was due on [date]. A copy is attached, and you can pay by [method]. Let me know if anything is holding it up.
- Second reminder: Hi [name], invoice [number] for [amount] is now overdue. Could you let me know the date we can expect payment? If there is a question about the invoice, tell me and I will sort it quickly.
- After a call: Thanks for the call today, [name]. As agreed, you will pay invoice [number] for [amount] by [date] using [method]. Please shout if that changes.
- Final notice: Hi [name], we have not received payment for invoice [number] for [amount], due on [date]. Please pay by [date]. If we do not hear from you, we will need to consider further steps.
Common mistakes to avoid
- Chasing an invoice that has already been paid, because nobody matched the payment.
- Sounding angry in the first message, when the delay may be a simple oversight.
- Sending reminders to your usual contact instead of the person who actually pays bills.
- Making vague requests like “please pay soon” instead of asking for a specific date.
- Threatening fees, interest or legal action you have not agreed in advance or are not allowed to apply.
- Leaving it for months, so the invoice gets harder to collect.

How long should I wait before chasing an unpaid invoice?
A few days after the due date is usually fine for a first, friendly reminder. Waiting longer gives the customer no signal that you are tracking it. If your customer is a large company, also ask early how its payment runs work, because some pay on fixed dates.
What should a polite payment reminder include?
Include the invoice number, the amount, the original due date, a copy of the invoice and a clear way to pay. Add a friendly line inviting questions. Keep it short, with one request per message. Specific details make it easy for the reader to act without looking anything up.
Can I charge late fees or interest on an overdue invoice?
Sometimes, but rules vary by country, state and customer type, and you generally need to have agreed the terms in advance. This guide gives general practice only, not legal advice. Check with a qualified accountant or lawyer in your area before adding fees or interest.
When should I use a collections agency or go to court?
Only after your own reminders, a phone call and a formal final notice have failed, and after taking advice. Collections and legal claims have strict rules that differ by location, and they can cost more than the invoice is worth. A qualified advisor can tell you what is allowed and worthwhile.
