Debt collection and data protection: which debtor data may be processed

This article explains debt collection and data protection: which debtor data may be processed 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.
Legal or professional starting point
The starting point is default. Under section 286 of the German Civil Code it arises through a reminder, but at the latest 30 days after the due date and receipt of the invoice; against consumers only if the invoice pointed out that consequence.
From the onset of default, interest can be charged: five percentage points above the base rate against consumers, nine percentage points where no consumer is involved. In business-to-business trade a flat fee of EUR 40 may also apply. A short status report at fixed intervals keeps the case transparent even after handover. A short note in the system replaces any later reconstruction from memory.
Requirements in detail
What needs checking is the conclusion of the contract, the service rendered, a proper invoice and the payment term. Only when this chain is unbroken do the consequences of default apply. Against consumers, the notice about the 30-day rule is added.
The invoice itself must contain the mandatory details so that it can be verified. Faulty invoices hand the debtor a convenient argument for holding back. When a file is handed to a collection agency, completeness of the paperwork is what determines how quickly work can begin. For the situation described here, the task is this: which debtor data may be processed.
Calculation and documentation
Interest is calculated to the day from the onset of default on the outstanding amount. The applicable base rate plus the statutory margin is decisive. Where default runs past an adjustment date, the period is calculated in sections.
Partial payments are recorded with their date and reduce the interest amount from the day of receipt. Without that allocation, differences arise that have to be explained later. Registered collection service providers in Germany operate under the Legal Services Act (RDG) and record every processing step verifiably. The earlier this point is clarified, the less time enforcement costs later.
Typical errors 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. 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. In debt collection, the combination of fast contact and a solid chain of evidence decides the prospects of recovery. The thread running through it stays the same: which debtor data may be processed.
Practical consequences for creditors
For creditors this means liquidity becomes more predictable once the consequences of default are asserted consistently. Ancillary claims are less a source of income than a signal that payment terms are meant seriously.
In ongoing customer relationships, clear but factual communication of the consequences works best. Transparency before the due date is more effective than pressure afterwards. It also matters to agree clearly who keeps contact with the debtor once the file has been passed on. Settling this point once removes the need to renegotiate it in every individual case later.
