Invoice is not paid despite a reminder: how to set the next deadline

Dealing with unpaid invoices does not begin with the reminder letter but with a clean starting position. The centre of attention here: How to set the next deadline. The more clearly the facts, the amount and the due date are documented, the less room a debtor has to delay. Standardisation reduces effort here far more than additional checking does.

The first few days decide whether a case runs as routine or as a special exception. A clear initial assessment keeps it in the routine. The more precisely an invoice describes the service delivered, the harder it is to delay payment with follow-up questions. The effort is one-off; the benefit repeats with every case.

Evidence is the currency in any dispute. What is needed: the contract or order confirmation, the invoice with number and date, proof of delivery or acceptance, the correspondence on the case and a statement of all payments received so far. What is prepared properly at this stage shortens every subsequent step.

Missing evidence can often be obtained retrospectively: delivery notes, timesheets, email confirmations or handover records. That effort is usually smaller than writing the receivable off. A brief confirmation of receipt from the customer saves a great deal of later discussion. Everything else is subordinate to this goal: How to set the next deadline.

The approach follows the calendar rather than instinct. Day one after the due date: check incoming payments. Days three to five: friendly reminder. Days ten to fourteen: formal reminder with a final period. After that period: decide on escalation. The earlier this point is clarified, the less time enforcement costs later.

Every stage should state the outstanding amount, the invoice number and the new deadline unambiguously. Collective reminders without a breakdown reliably produce queries rather than payments. For recurring services, a consistent invoice structure prevents queries from arising in the first place. That keeps the case understandable for colleagues with no prior knowledge of it.

The most common mistake is waiting. Reacting only after months costs information, contacts and, in an insolvency, part of the dividend. Equally critical are vague deadlines such as "immediately", missing proof that the invoice was received, and reminders without an itemised breakdown. Small improvements here work through the entire receivables portfolio.

The limitation period is often underestimated as well: the standard period is three years and starts at the end of the year in which the claim arose. Overlooking it means losing enforceable claims for no reason. When an invoice stays unpaid, proof of delivery and of the invoice content is the first point to be checked. Applied to this topic it means: How to set the next deadline.

The right moment for handover is largely a resource question. As soon as the internal effort per case exceeds the expected return, outsourcing is worthwhile. Fortis Inkasso works as a registered collection service provider and can take on cases individually or in batches. This care costs minutes and saves days if the matter is ever disputed.

A handover requires the invoice, the contractual basis, proof of performance, the reminder history and current debtor data. The more complete the package, the faster processing starts. Unpaid invoices often have a formal cause: a missing purchase order number, the wrong recipient or an unclear description of services. A fixed cycle is more effective than a review that only happens when someone asks for it.
