You sent the invoice. The due date passed. Nothing.
Most freelancers and small businesses will face this at some point. How you handle it matters — both for recovering the money and for deciding whether the client relationship is worth keeping.
Here's a step-by-step process that works.
Step 1: Check Before You Chase (Day 1 Overdue)
Before you send anything, rule out the obvious:
- Did the invoice actually go out? Check your sent folder.
- Did it land in spam? Common with automated invoice emails.
- Is the due date what you think it is? Double-check the invoice.
- Did you send it to the right person? Finance teams often have a separate billing contact.
One missed payment is almost never malicious. It's usually a lost email, a missed approval, or a contact who left the company. Start from that assumption.
Step 2: A Friendly Reminder (Day 1–3 Overdue)
Send a short, neutral email. No guilt, no pressure — just a prompt.
Hi [Name],
>
Just a quick note that invoice #[number] for [amount] was due on [date]. Please let me know if you have any questions or if there's anything you need from me to process payment.
>
[Your name]
Keep it to three sentences. A friendly nudge resolves the majority of late payments at this stage.
If you have a phone number for the client, a quick call often works faster than email. People are more likely to commit to a date when asked directly.
Step 3: A Firmer Follow-Up (Day 7–10 Overdue)
If you haven't heard back, escalate the tone slightly. Reference the previous message and state a clear expectation.
Hi [Name],
>
Following up on my message from [date] regarding invoice #[number] for [amount], now [X] days overdue.
>
Could you confirm when payment will be processed? If there's an issue with the invoice or the payment method, I'm happy to help resolve it.
>
[Your name]
At this point, also consider: is there someone else at the company you should be contacting? If your main contact is a project manager, the actual payment may need to go through accounts payable. Ask directly: "Is there a billing contact I should follow up with?"
Step 4: Formal Notice (Day 14–21 Overdue)
If the invoice is now two to three weeks overdue with no response or no clear payment date, send a formal notice. This is different in tone — it documents the situation and creates a paper trail.
- Reference all previous contact attempts with dates
- State the original due date and current outstanding amount
- Include any late fee that applies (per your invoice terms)
- Set a firm deadline: "Please arrange payment by [specific date]."
- State what happens next: "If payment is not received by that date, I will need to consider further action."
Send this by email and keep a copy. If you have a physical address, sending a copy by post creates an additional record.
Step 5: Put Future Work on Hold
If the client has ongoing work with you and hasn't paid an overdue invoice, pause delivery.
You don't need to make it confrontational. A simple note works: "I've put a hold on [project/deliverable] until the outstanding invoice is settled."
This is both reasonable and effective. Clients who owe you money have a strong incentive to pay when continued work depends on it.
Step 6: Formal Debt Recovery Options
If you've reached this point — three weeks or more overdue, no response or broken promises — you have several options:
Debt collection agency. A professional agency will chase the debt for a percentage of what they recover (typically 15–25%). You give up some of the amount but offload the effort and add credibility to the chase. Most agencies won't touch claims under a few hundred pounds/euros, so this is more suitable for larger invoices.
Small claims court. In most countries, there's a simple process for claiming small amounts (up to £10,000 in the UK, €2,000 in many EU countries) through a small claims procedure. It's relatively low-cost and doesn't require a solicitor. The threat of legal action alone often prompts payment.
Statutory demand (UK). For amounts over £750 owed by a limited company, a statutory demand is a formal legal notice that can lead to winding-up proceedings. It sounds dramatic, but receiving one tends to focus attention quickly. Get legal advice before using this route.
Invoice factoring. Some businesses sell overdue invoices to a factoring company at a discount in exchange for immediate cash. Worth knowing about, but usually only relevant for businesses with recurring, larger invoices.
What to Do About the Relationship
Here's the question most guides skip: should you keep working with this client?
A client who pays late once, apologises, and settles the invoice promptly is probably worth keeping. Delays happen.
A client who ignores follow-ups, disputes an invoice without basis, or repeatedly pays late is a business risk. Every hour you spend on a non-paying client is an hour not spent on a paying one.
If you decide to keep the relationship, set different terms going forward: a deposit before work starts, milestone payments, or shorter payment windows. You've earned the right to ask.
If you decide to end it, do so cleanly and in writing, with all outstanding amounts documented.
How to Reduce the Problem Going Forward
- Require a deposit. Even 25–30% upfront screens out unreliable clients and gives you something to hold on to.
- Invoice immediately. Don't wait until the end of the month. Invoice when the work is done.
- Include late payment terms on every invoice. A stated fee — even one you'll never enforce — changes behaviour.
- Get a signed agreement. A simple project brief or terms of engagement, signed before work starts, makes disputes much harder for clients to sustain.
Late payment is one of the most common problems in freelance and small business work. Having a consistent process — and following it calmly and systematically — is the best defence.
