How to Chase Unpaid Invoices (Without Burning the Relationship)

The hardest part of chasing late invoices isn't legal — it's emotional. You don't want to look pushy, you don't want to damage a client relationship, and you definitely don't want to send the angry email you've been drafting in your head. So you wait. Then you wait some more. And the invoice gets older, the relationship cools off anyway, and you end up sending a much more uncomfortable email three months later.

Most late payments aren't malicious. They're the result of someone forgetting, an AP system snagging on a missing PO number, or a finance director sitting on approvals while they're on holiday. A calm, predictable chase sequence solves all three — without making either side uncomfortable.

The five-touch sequence

Time these from your due date. Each touch has a different tone and a different purpose. Don't skip steps and don't deviate from the schedule — the predictability is what makes it feel professional rather than pushy.

1. T-3 days (before due): Friendly reminder. “Just a quick note that invoice INV-014 is due Friday. Let me know if you need anything from me to process it.”
2. Day 0 (due date): Receipt request. “Invoice INV-014 is due today — can you confirm it's in your payment run?”
3. Day +7: First overdue notice. Polite, factual, references your payment terms.
4. Day +14: Second overdue notice. Same tone, but mentions escalation: “If we can't resolve this by Friday, I'll need to send a formal demand.”
5. Day +30: Formal demand. Statutory interest claim, copy to the client's manager, last step before escalation to small claims or a collection agency.

Templates for each stage

Touch 1 — Friendly reminder (T-3 days)

Hi {name},

Quick heads-up: invoice INV-014 (€4,500) is due Friday, 16 April. No action needed if everything's on track — just want to make sure it didn't get stuck anywhere. Happy to resend the PDF if you can't find it.

Best, {you}

The point of this touch isn't to chase — it's to surface any issue early. If the client's AP system needs a PO number you didn't include, you'll find out now instead of two weeks after the due date.

Touch 2 — Receipt request (Day 0)

Hi {name},

Invoice INV-014 is due today. Can you confirm it's scheduled in this week's payment run? Reference for your records: INV-2026-014, €4,500, issued 2 April.

Thanks, {you}

Specific, factual, no pressure. The included reference makes the client's AP lookup faster.

Touch 3 — First overdue notice (Day +7)

Hi {name},

Invoice INV-014 (€4,500, issued 2 April) is now 7 days overdue. Could you let me know where it stands? If there's anything you need from me to release payment, I'm happy to help.

Our agreed terms are net 14, so this is now outside those. I want to flag it early in case there's an internal blocker.

Thanks, {you}

Notice the tone: factual, references the agreement, offers to help. You're not accusing — you're drawing attention to the deviation from what you both agreed.

Touch 4 — Second overdue notice (Day +14)

Hi {name},

Following up on invoice INV-014, now 14 days overdue. I haven't heard back on the last reminder, so I want to make sure this hasn't fallen off the radar.

If we can't get this resolved by end of next week (24 April), I'll need to send a formal demand and add statutory late-payment interest. Hoping it doesn't come to that — please let me know if there's a way I can help.

Best, {you}

This is where the escalation language enters. You're still polite, but you've set a concrete next step and a date. Most invoices get paid between Touch 4 and Touch 5.

Touch 5 — Formal demand (Day +30)

Hi {name} — cc'ing {their manager},

Invoice INV-014 (€4,500, issued 2 April, due 16 April) is now 30 days overdue. I've sent four reminders and haven't had a response on payment timing.

Under the EU Late Payment Directive 2011/7/EU, I'm entitled to statutory interest of 8% above ECB base rate plus a €40 fixed recovery fee. Updated invoice with interest accrued: INV-014-A, attached.

If this isn't resolved by 7 May, I'll refer the matter to a debt collection service / small claims court. I'd rather not — please let's get this closed this week.

{you}

The formal demand cc's their manager and references statutory rights. It's firm, but it doesn't insult anyone. At this point you have a paper trail you can hand to a collector or court.

When to escalate beyond email

After Day +30, you have three realistic paths:

• Debt collection agency. They take 10–25% of the recovered amount but handle everything. Worth it for invoices over €1,000.
• Small claims court. In most EU countries this is cheap (€50–€200 filing fee) and the procedure is designed for non-lawyers. The European Small Claims Procedure (Regulation EC 861/2007) works for cross-border claims under €5,000.
• Walking away. Sometimes the cost of chasing exceeds the invoice. If you do walk away, file a 1099-style loss with your accountant and never work with that client again.

The EU statutory right most freelancers miss

The EU Late Payment Directive (2011/7/EU) gives every business in the EU — including sole traders and freelancers — three automatic rights when a B2B payment is late:

• Interest at 8 percentage points above the ECB reference rate, calculated daily from the day after the due date.
• A flat €40 recovery fee per late invoice, regardless of size.
• The right to claim reasonable additional recovery costsbeyond the €40 (lawyer fees, collection agency fees).

You don't have to negotiate these — they apply automatically the day after the due date passes. You can waive them, but the contract clause that waives them is unenforceable if it's “grossly unfair” (Article 7 of the directive). In practice, citing the directive in your Touch 5 demand is often enough to get payment without going further.

FAQ

Should I add a late fee to the invoice itself?

Including a clause on the invoice (“Late payments accrue 8% above ECB base rate per Directive 2011/7/EU”) is a signal — it tells the AP team you know your rights and that late payment isn't cost-free for them. It also gives you a clean basis for actually charging it later.

What if my client is outside the EU?

The EU directive doesn't apply, but most jurisdictions have equivalent statutory interest rules (US: state-by-state; UK: Late Payment of Commercial Debts Act, 8% above Bank of England base rate + recovery fees). Check your client's jurisdiction; the chase sequence still works.

How do I keep chasing without seeming hostile?

Stick to the schedule, keep emails short and factual, and always offer to help. The hostility usually creeps in when freelancers vary from the script — long emotional emails, mid-sequence apologies, or surprise escalations. A predictable rhythm reads as professionalism, not pressure.
