I once had a retail client who owed me 8,400 euros across three invoices. Seventy days. The kind of situation where you check your bank account every morning with a knot in your stomach. I tried everything: the polite email, the 'just a gentle reminder', the casual WhatsApp message. Nothing. What finally broke the deadlock was a structured follow-up approach, sent on the right day, to the right person, with the right tone. No magic. A method.
Late payments are the Achilles heel of every service-based business. Freelancers, agencies, independent consultants: according to Altares data, nearly a third of business failures are directly linked to payment delays, not bad products or unhappy clients. Just cash that never showed up on time.
Why We Avoid Chasing (And Why That's a Mistake)
Most freelancers and small agencies delay chasing because it feels uncomfortable. Nobody wants to look pushy, irritate a client they're hoping to keep, or 'ruin the vibe' after a good project. That's understandable. It's also terrible business logic.
Your client has zero discomfort paying you 45 days late. Their CFO has priorities. Their assistant has other fires. Your invoice is somewhere between a Salesforce quote and a team-building invite. You need to take back control. Chasing is not aggression. It's management.
"The day I stopped apologising for following up, my average payment time dropped from 58 days to 29. Without losing a single client." — Camille, co-director of a UX agency in Lyon, 12-person team
The Follow-Up Timeline I Actually Use
D-3 Before Due Date: The Proactive Courtesy Email
Three days before the due date, I send a short email. Subject: 'Invoice #XXXX - due in 3 days'. Body: two lines, amount, direct PDF link, bank details. No apology, no 'I hope this isn't a bother'. This single email resolves around 40% of cases. Many late payments start with a lost invoice.
D+1 to D+7: Firm but Professional Follow-Up
The invoice is overdue. I send a neutral, factual email. Not aggressive, not grovelling. 'Invoice #XXXX for the amount of X euros was due on [date]. Could you confirm the expected payment date?' A closed question that demands a concrete answer.
D+15: Change Your Contact
Nothing at D+15 means your operational contact cannot or will not act. Escalate: CFO, managing partner, director. This isn't a betrayal of your contact. It's risk management. In 80% of cases where I escalated, payment arrived within five days.
D+30: Formal Notice
Send a formal letter. 'Notice of payment demand.' This phrase has an immediate psychological effect and is the first legal step before a payment order. In most cases, this letter alone resolves the situation within a week.
Automating Without Losing the Human Touch
Tools like Clynt, Pennylane or QuickBooks offer automated follow-up sequences. I get annoyed when I receive a robotic chase from a provider I've worked with for two years. For high-volume agencies managing 40 to 80 invoices a month, partial automation is essential. But humanise anything you send after D+7. Automate the monitoring, personalise the message.
The Contract Clause Everyone Forgets
The most underused lever is the original contract. If your T&Cs don't mention late payment penalties, a suspension clause, or the flat-rate debt recovery indemnity (40 euros mandatory in B2B in France under the LME), you're waiving rights the law grants you automatically. Mention the 40-euro indemnity in your first overdue email. It signals that you know your rights. Clients who realise that tend to pay faster.
When the Client 'Disputes' to Buy Time
Classic tactic: the invoice is 45 days old and suddenly your client has 'concerns about the deliverable.' First check: do you have a signed quote or purchase order? Is delivery documented in writing? If yes, the dispute has no legal basis. Respond with facts, maintain the follow-up sequence. If the dispute is real and partial, isolate the contested amount, settle that conversation separately, and chase the uncontested portion immediately.
FAQ
How many days overdue before sending a formal payment notice?
There is no minimum legal waiting period in B2B contexts. In practice, aim for 21 to 30 days after the due date, after at least two friendly follow-ups. Waiting longer signals to the client that there is no urgency.
Can you pause an ongoing project if a client doesn't pay?
Yes, but only if your contract explicitly includes a suspension clause for non-payment. Without it, stopping work can expose you to a claim for wrongful termination. Always verify your T&Cs before acting. Tools like Clynt let you embed standard suspension clauses directly into electronically signed quotes.
How do you chase a key account without damaging the relationship?
Separate the relationship from the process. Use formal channels for the follow-up and keep your normal relationship warm in parallel. Most solid clients respect a supplier who manages their finances seriously. What damages relationships is ambiguity and accumulation, not clarity.
What are the options if a client still refuses to pay after formal notice?
Three main routes: a payment order (fast, low-cost, effective for smaller amounts), emergency court proceedings for larger undisputed sums, or assignment to a debt collection agency (you lose a portion of the debt but eliminate admin effort). For most freelancers and agencies, the payment order is the most accessible and fastest path.
