How to Collect Overdue Invoices
Late payments cost businesses thousands in lost revenue and wasted time. The average B2B invoice is paid 8 days late. This guide shows you 7 proven strategies to collect overdue invoices faster — and how to prevent them from going overdue in the first place.
Prevention: Stop Invoices From Going Overdue
The best overdue invoice is one that never becomes overdue. These practices dramatically reduce late payments before they happen.
Send Invoices Immediately
The sooner you invoice, the sooner you get paid. Businesses that send invoices within 24 hours of delivering a service get paid 2x faster than those who wait a week or more. With PayRequest, invoices are generated automatically based on your billing schedule.
Make Payment Easy
Every friction point in the payment process adds days to your payment timeline. Include a "Pay Now" button directly in the invoice email that takes customers to a payment page with iDEAL, cards, SEPA, and other methods. If paying takes more than 3 clicks, you're losing money.
Set Clear Payment Terms
State your payment terms clearly on every invoice: due date, accepted payment methods, and late payment consequences. Net-14 performs better than Net-30 for most B2B businesses — shorter terms create urgency without being unreasonable.
Send Pre-Due Reminders
A friendly reminder 3 days before the due date increases on-time payment by 30%. It's not nagging — it's a courtesy that helps busy clients plan their payments. PayRequest sends these automatically.
7 Strategies to Collect Overdue Invoices
Automated Payment Reminders
Set up a sequence of automated emails that escalate in tone as the invoice ages. This is the highest-ROI strategy because it runs without your involvement.
- Day 1 past due: Friendly reminder — 'Just a heads up, invoice #X is due today'
- Day 3 past due: Follow-up — 'Your invoice is now 3 days overdue. Click here to pay'
- Day 7 past due: Firmer tone — 'Action required: Invoice #X is 7 days overdue'
- Day 14 past due: Final notice — 'Your account will be escalated if not paid within 48 hours'
Tip: PayRequest's dunning system automates this entire sequence. Set it up once and it handles every overdue invoice automatically.
Pick Up the Phone
After automated reminders, a personal phone call is the most effective collection method. People ignore emails but take phone calls. Keep it professional — ask if there's a problem with the invoice and offer to help resolve it.
- Call between day 7-14 if automated reminders haven't worked
- Ask: 'I noticed invoice #X is outstanding — is everything OK?'
- Often the invoice was simply lost or forgotten
- Document the conversation and agreed payment date
Tip: Many overdue invoices aren't deliberate. The client may have changed email addresses, lost the invoice, or simply forgotten. A call usually resolves it.
Offer a Payment Plan
If a customer genuinely can't pay the full amount, offering a payment plan gets you paid over time instead of not at all. Split the invoice into 2-4 monthly payments.
- Suggest splitting into manageable installments
- Use PayRequest's subscription feature to automate the payment plan
- Get the first installment before finalizing the agreement
- Document the plan in writing (email confirmation is sufficient)
Tip: A payment plan that collects 100% over 3 months is better than writing off the invoice entirely. PayRequest can create recurring payment links for installments.
Add Late Payment Fees
Late payment fees create financial incentive to pay on time. In the EU, businesses are legally entitled to charge interest on late B2B payments (currently 8% + ECB base rate). Include this in your terms and conditions.
- State late payment fees clearly in your terms (ideally before invoicing)
- EU directive allows 8% + ECB base rate on overdue B2B invoices
- Also allowed: a fixed €40 recovery cost per overdue invoice (EU Directive 2011/7)
- Apply fees consistently — selective enforcement undermines credibility
Tip: The threat of late fees is often more effective than the fees themselves. Most clients pay faster when they know penalties exist.
Pause Services Until Paid
For ongoing service relationships, pausing service delivery is a powerful motivator. This works best for subscriptions, hosting, retainers, and managed services.
- Send a clear warning before pausing (e.g., 'Service will be paused in 48 hours')
- Pause non-critical services first (reports, new features) before core services
- Resume immediately upon payment to maintain the relationship
- PayRequest can automatically suspend access through the customer portal
Tip: Always give advance warning before pausing. Sudden service cuts damage relationships and may have legal implications depending on your contract.
Send a Formal Demand Letter
A formal written demand (sometimes called a 'letter before action') signals that you're serious about collecting. Many businesses pay immediately upon receiving one because they want to avoid legal costs.
- Send via registered mail or email with read receipt
- Include: invoice number, amount, original due date, total interest accrued
- State a final deadline (typically 14 days)
- Mention that you'll consider further action if payment isn't received
Tip: Keep the tone professional and factual. Emotional or threatening language weakens your position if the case goes further.
Use a Collection Agency or Legal Action
As a last resort for large unpaid amounts, a collection agency or small claims court can recover the debt. Collection agencies typically charge 10-25% of the recovered amount.
- Collection agencies handle communication and follow-up for you
- Small claims court works for amounts under €25,000 in most EU countries
- The European Payment Order procedure simplifies cross-border B2B collection
- Document everything — emails, reminders, agreements — as evidence
Tip: Before engaging a collection agency, send one final email: 'If payment is not received by [date], we will refer this to our collection partner.' This final warning recovers 20-30% of remaining cases.
Automate Your Invoice Collection
Manual follow-up doesn't scale. When you have 50+ clients, tracking who's overdue and sending reminders becomes a full-time job. Automation handles it better.
- Automatic reminders sent on schedule — no manual tracking
- Escalating tone from friendly to firm without your involvement
- One-click payment links in every reminder email
- Customer portal where clients can pay outstanding invoices 24/7
- Dashboard showing all overdue invoices with aging breakdown
- Automatic late fee calculation and application

Frequently Asked Questions
When should I start following up on overdue invoices?
Start with a friendly automated reminder on the day the invoice is due, then follow up at day 3, 7, and 14. The sooner you follow up, the higher your recovery rate. Most businesses wait too long — by day 30, recovery rates drop significantly.
Can I charge interest on overdue B2B invoices?
Yes, in the EU you're legally entitled to charge interest on late B2B payments under the Late Payment Directive (2011/7/EU). The rate is 8% + the ECB base rate, and you can also charge a fixed €40 recovery cost per invoice. These rights apply automatically, even without mentioning them in your contract.
What is dunning?
Dunning is the process of systematically following up on overdue payments through automated reminders, escalating in urgency over time. Modern dunning software like PayRequest sends email sequences, offers one-click payment links, and tracks which invoices need attention — all automatically.
How do I prevent invoices from going overdue?
Four key practices: send invoices immediately after service delivery, include a one-click 'Pay Now' button, use shorter payment terms (Net-14 instead of Net-30), and send automated reminders 3 days before the due date. PayRequest automates all of these.
Should I offer payment plans for overdue invoices?
Yes, when a customer genuinely can't pay the full amount. Collecting 100% over 3 months is better than writing off the invoice. PayRequest makes this easy with recurring payment links that automate installment collection.
