Customer Not Paying an Invoice? What to Do | Atradius Collections

What should I do if a customer won’t pay?

When a customer fails to pay an invoice by the agreed due date, begin structured follow-up without delay. Early, consistent action supports higher recovery rates and helps you maintain control of the communication process as the debt ages.

Unpaid B2B invoices can often still be recovered successfully with a clear escalation process. However, recovery outcomes generally depend on timing, communication discipline, and when you engage external support.

This article outlines how overdue B2B invoices are typically managed, when escalation is generally considered, and how recovery approaches differ across key international markets.

Considerations in early-stage payment delays

Most overdue invoices do not originate from deliberate non-payment. In practice, delays often stem from internal processing cycles, administrative errors, cash-flow timing, or organisational changes within the debtor company.

As time progresses, however, the likelihood increases that communication becomes less responsive, documentation becomes disputed, or the invoice is deprioritised within internal payment workflows.

For this reason, structured follow-up is generally more effective than ad hoc reminders. A consistent escalation framework helps maintain visibility of the receivable and reduces uncertainty in the recovery process.

These dynamics are further amplified in international trade, where differences in language, legal systems, and payment behaviour can affect responsiveness and resolution timelines.

Typical recovery process for chasing unpaid invoices

Day 0: Verification of invoice details

Before initiating escalation, it is standard practice to confirm that the invoice has been issued correctly and delivered to the appropriate contact.

Delays often stem from operational issues such as incorrect purchase order references, missing supporting documentation, or internal changes in the debtor’s accounts payable structure.

In many cases, reissuing the invoice and confirming receipt is enough to resolve the delay without further action.

Day 1: Initial payment reminder

Once the due date has passed, you generally issue an initial written reminder.

At this stage, the purpose is to re-establish visibility of the outstanding invoice and ensure it is actively processed within the debtor organisation. Communication is typically factual and includes key invoice details such as reference number, amount, and due date.

Early follow-up is often associated with better recovery performance than delayed or inconsistent contact.

Day 7 to 14: Structured follow-up and clarification

If payment remains outstanding, follow-up is typically intensified through both written communication and direct contact with accounts payable or relevant decision-makers.

The objective at this stage is to determine whether the delay is administrative, financial, or related to a potential dispute. Where a dispute exists, it is generally documented and addressed in writing before further escalation continues.

If no dispute is identified, the focus typically shifts to confirming a payment date and maintaining structured follow-up.

Day 21 to 30: Formal demand stage

Where earlier reminders have not resulted in payment, a formal demand is typically issued.

This stage indicates that the case is moving beyond routine credit control into a more structured recovery phase. The demand generally outlines the outstanding balance, any applicable interest or contractual recovery costs, and a defined payment deadline.

At this point, many businesses assess whether external support is appropriate, particularly where internal follow-up has not produced resolution.

Day 30 to 60: Amicable collections

If the debt remains unpaid, the case is often transferred to an amicable collections process.

Amicable recovery focuses on resolving the outstanding balance through structured engagement while preserving the underlying commercial relationship where possible. This may include ongoing negotiation, repeated contact attempts, and local-language communication where relevant.

In cross-border cases, local teams or representatives can be an important factor in achieving effective engagement, particularly where cultural or procedural differences influence payment behaviour.

Day 60 to 90: Assessment of legal recovery options

Where amicable recovery does not result in payment, the next stage is typically an assessment of legal recovery options.

This assessment generally considers factors such as the value of the debt, available documentation, debtor solvency, jurisdiction, and expected enforcement pathways. In some cases, structured legal procedures may offer more efficient routes to recovery than standard litigation.

At this stage, many organisations also assess the cost-effectiveness of continued recovery efforts against the outstanding amount.

Debt recovery in the European Union

Within the European Union, Directive 2011/7/EU on combating late payment in commercial transactions establishes a framework of protections for B2B creditors.

In many Member States, creditors are entitled to statutory late-payment interest from the day after the agreed due date, plus fixed compensation for recovery costs and reimbursement of reasonable additional expenses, where applicable.

While implementation varies across jurisdictions, the underlying principle remains consistent: late payment should not allow one business to finance another through extended payment delays.

For cross-border claims within the EU, structured legal instruments such as the European Order for Payment may offer more streamlined recovery pathways in certain cases.

Debt recovery across Asia-Pacific markets

Debt recovery practices across Asia-Pacific vary significantly between jurisdictions, including markets such as China, Singapore, Japan, India, and across Southeast Asia.

In several markets, maintaining the commercial relationship is an important consideration during early-stage recovery. At the same time, delays in escalation can increase complexity where communication slows or financial pressure increases within the debtor organisation.

Local language capability and understanding of regional business practices are often relevant factors in recovery effectiveness. Differences in legal frameworks and enforcement processes mean that recovery strategies typically need to be adapted to the specific jurisdiction.

In markets such as Singapore, dispute resolution processes are generally considered more structured, while other jurisdictions may require additional procedural steps depending on the nature of the claim.

Disputed invoices

Where an invoice is formally disputed, it is generally treated separately from standard overdue payment cases.

Assess, document, and address disputes before further escalation. This helps ensure that the recovery process remains aligned with the underlying commercial agreement.

It is also recognised that disputes may be raised after payment reminders have commenced. In such cases, clear documentation and structured claim handling are important to maintain an effective recovery process.

What to do when a customer ghosts payment?

When a debtor becomes unresponsive after repeated reminders or a formal demand, this typically indicates that escalation is required.

Non-response may stem from administrative issues, financial pressure, or intentional avoidance. In all cases, further delay generally reduces the likelihood of resolving the matter through informal channels.

At this stage, structured recovery processes are commonly used to re-establish contact, assess recoverability, and determine appropriate next steps based on jurisdiction and case specifics.

Frequently asked questions

How soon should I chase an unpaid invoice?

The sooner, the better. Send the first reminder as soon as the invoice becomes overdue—statutory interest is already accruing, and early action strengthens your position while encouraging timely payment.

Can I charge interest on an overdue B2B invoice in the EU?

Yes. Under EU Directive 2011/7/EU, you’re entitled to statutory interest of at least 8 percentage points above the ECB reference rate, a €40 minimum recovery fee, and reasonable additional collection costs. These rights apply automatically once the invoice is late, giving you a strong legal basis to recover what’s owed.

When should I hand the case over to a collection agency?

Most credit teams escalate cases between 60 and 90 days overdue. Acting sooner often improves recovery rates, particularly if the debtor has gone silent or shows signs of financial difficulty. Professional support at the right time helps safeguard your cash flow and frees your team to focus on running your business.

Will using a collection agency damage the customer relationship?

Not when you work with a trusted agency. Atradius Collections prioritises amicable, pre-legal recovery — professional, structured engagement that respects local language, norms, and jurisdiction. In most cases, the relationship survives, and your customer’s payment behaviour improves.

What if the customer is in another country?

International collections can be difficult and complicated. Atradius Collections has local teams in many countries around the world who speak the local language, understand the culture and know the local laws and customs. This helps ensure your cross-border invoices are handled efficiently, professionally, and successfully.
