This article explains invoice is not paid: seven steps from the due date to debt collection in the context of German receivables management. It is written for companies, self-employed professionals, accounts receivable teams and creditors that need a clear, documented next step. Fortis Inkasso GmbH & Co. KG can support professional debt collection processes; the article does not replace case-specific legal advice.

Starting point: Seven steps from the due date to debt collection

The first question is always how solid the claim actually is. The focus: Seven steps from the due date to debt collection. Separating the due date, proof of performance and the communication trail quickly shows whether this is a liquidity problem, a clarification problem or a process problem. What is prepared properly at this stage shortens every subsequent step.

In practice this means reconciling payment terms, invoice date and incoming payments before any contact is made. Only then can you judge whether this is a genuine payment problem or a case that simply needs clarification. When an invoice stays unpaid, proof of delivery and of the invoice content is the first point to be checked. That keeps the case understandable for colleagues with no prior knowledge of it.

Requirements and documents

Before escalating unpaid invoices, the file has to be complete. That includes the contract or order confirmation, the invoice with all mandatory details, proof of delivery or performance and the full correspondence. If one element is missing, the evidential position shifts quickly against the creditor. Settling this point once removes the need to renegotiate it in every individual case later.

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. Unpaid invoices often have a formal cause: a missing purchase order number, the wrong recipient or an unclear description of services. Applied to this topic it means: Seven steps from the due date to debt collection.

Step-by-step approach

A reliable approach follows fixed stages rather than instinct. First the payment status is checked, then a factual payment reminder follows, then a formal reminder with an unambiguous final deadline. If payment still fails to arrive, the court dunning procedure or a handover to a collection agency are the options. The effort is one-off; the benefit repeats with every case.

Every stage needs a date, a channel and an owner. Follow-up dates are stored in the system so that no deadline lapses and no case is left sitting. The more precisely an invoice describes the service delivered, the harder it is to delay payment with follow-up questions. A short note in the system replaces any later reconstruction from memory.

Common mistakes and risks

Typical risks arise less from legal questions than from process gaps. These include incomplete invoices, partial payments that were never allocated, outdated address data and a tone that escalates too early and reduces willingness to pay. A fixed cycle is more effective than a review that only happens when someone asks for it.

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. A brief confirmation of receipt from the customer saves a great deal of later discussion. Translated into practice this means: Seven steps from the due date to debt collection.

When Fortis can be involved

Not every case belongs outside the company immediately. Handover is sensible when deadlines and contact attempts are exhausted, the amount justifies the effort and the documents are complete. Fortis Inkasso operates as a registered collection service provider. This care costs minutes and saves days if the matter is ever disputed.

No promise about the outcome is possible, and this article does not replace case-specific legal advice. It does show which steps should sensibly be completed before instructing an agency. For recurring services, a consistent invoice structure prevents queries from arising in the first place. Small improvements here work through the entire receivables portfolio.
